<p>This document provides an overview of the process to upgrade the Perforce Helix Server Deployment Package (SDP) from any older version (dating back to 2007) to the SDP 2020.1 release, also referred to as "r20.1".</p>
</div>
<div class="paragraph">
<p>If your SDP version is 2020.1 or newer, refer to the <a href="SDP_Guide.Unix.html">SDP Guide (Unix)</a> for instructions on how to upgrade from SDP 2020.1 to any later version. Starting from SDP 2020.1, the upgrade procedure for the SDP is aided by an automated and incremental upgrade mechanism similar to p4d itself, capable of upgrade SDP from the current release to any future version so long as the current release is SDP 2020.1 or newer.</p>
</div>
<div class="paragraph">
<p>This document describes the process of upgrading to SDP 2020.1.</p>

<div class="sect1">
<h2 id="_overview">1. Overview</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The Perforce Server Deployment Package (SDP) software package, just like the Helix Core software it manages, evolves over time and requires occasional upgrades to remain supported. Further, patches may be released over time.</p>
</div>
<div class="paragraph">
<p>This document discusses how to upgrade the SDP, and when in relationship to Helix Core itself.</p>
</div>
<div class="sect2">
<h3 id="_upgrade_order_sdp_first_then_helix_p4d">1.1. Upgrade Order: SDP first, then Helix P4D</h3>
<div class="paragraph">
<p>The SDP should be upgraded prior to the upgrade of Helix Core (P4D). If you are planning to upgrade P4D to or beyond P4D 2019.1 from a prior version of P4D, you <em>must</em> upgrade the SDP first. If you run multiple instances of P4D on a given machine (potentially each running different versions of P4D), upgrade the SDP first before upgrading any of the instances.</p>
</div>
<div class="paragraph">
<p>The SDP should also be upgraded before upgrading other Helix software on machines using the SDP, including P4D, P4P, P4Broker, and the 'p4' command line client on the server machine. Even if not strictly required, upgrading the SDP first is <strong>strongly</strong> recommended, as SDP keeps pace with changes in the p4d upgrade process, and can ensure a smooth upgrade.</p>
</div>
</div>
<div class="sect2">
<h3 id="_upgrading_helix_p4d_and_other_software">1.2. Upgrading Helix P4D and Other Software</h3>
<div class="paragraph">
<p>See the <a href="SDP_Guide.Unix.html">SDP Guide (Unix)</a> for instructions on how to upgrade Helix binaries in the SDP structure after the SDP has been upgraded to 2020.1 or later.</p>
</div>
</div>
<div class="sect2">
<h3 id="_sdp_and_p4d_version_compatibility">1.3. SDP and P4D Version Compatibility</h3>
<div class="paragraph">
<p>The SDP is often forward- and backward-compatible with P4D versions. However, for best results they should be kept in sync by upgrading SDP before P4D. This is partly because the SDP contains logic to upgrade P4D, which can change as P4D evolves.</p>
</div>
<div class="paragraph">
<p>The SDP is aware of the P4D version(s) it manages, and has backward-compatibility logic to support older versions of P4D. This is guaranteed for supported versions of P4D. Backward compatibility of SDP with older versions of P4D may extend farther back then officially supported versions, though without the "officially supported" guarantee.</p>

<p>There are several methods for upgrading to a new version of the SDP:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><strong>In-Place, Manual Upgrades</strong>: Manual upgrades of the SDP must be performed to upgrade from versions older than 2020.1 in-place on existing machines. This document provides details on how to do this.</p>
</li>
<li>
<p><strong>In-Place, Automated Upgrades</strong>: Automation assisted in-place upgrades can be done if your current SDP version is 2020.1 or later. and you are upgrading to 2021.1 and later. Refer to documentation in <a href="SDP_Guide.Unix.html">SDP Guide (Unix)</a> for upgrading <em>from</em> SDP 2020.1 onward.</p>
</li>
<li>
<p><strong>Migration-Style Upgrades</strong>: A migration-style upgrade is one in which the existing server machines (virtual or physical) are left in place, and brand new "green field" machines are installed fresh using the <a href="https://swarm.workshop.perforce.com/projects/perforce_software-helix-installer">Helix Installer</a> (which installs the latest SDP on a "green field" baseline machine with only the operating system installed). Then the Helix Core data is migrated from the existing hardware to the new hardware. This approach is especially appealing when upgrading other aspects of the infrastructure at the same time as the SDP, such as the hardware and/or operating system. Migration style upgrades require new hardware, and provide a straightforward rollback option because the original hardware is left in place.</p>
</li>
<li>
<p><strong>Custom with HMS</strong>: The <a href="https://swarm.workshop.perforce.com/projects/perforce_software-hms">Helix Management System</a> is used by some customers. See <a href="#_custom_hms_managed_installations">Appendix 3.A, <em>Custom HMS Managed Installations</em></a></p>

<div class="sectionbody">
<div class="paragraph">
<p>Legacy SDP upgrades require some familiarization that should be done prior to scheduling an upgrade.</p>
</div>
<div class="paragraph">
<p>The following information is useful for planning SDP in-place upgrades.</p>
</div>
<div class="sect2">
<h3 id="_plan_what_is_being_upgraded">2.1. Plan What Is Being Upgraded</h3>
<div class="paragraph">
<p>Presumably if you are reading this, you are intending to upgrade the SDP. During planning, you’ll want to decide if you want to upgrade only the SDP. Or you may want to upgrade Helix Core software in the same maintenance window.</p>
</div>
<div class="paragraph">
<p>Tactically, the SDP upgrade is done first. However, upgrading SDP and Helix Core can be done in the same maintenance window, so both upgrade tasks can be done in one upgrade session. Alternately, Helix Core can be upgraded at a later date after the SDP upgrade.</p>

<h3 id="_upgrade_duration">2.2. Upgrade Duration</h3>
<div class="paragraph">
<p>Key questions to answer during upgrade planning are:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Will p4d need to be taken offline?</p>
</li>
<li>
<p>If so, how long?</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>Most upgrades to SDP to 2020.1 will require downtime for the Helix Core (p4d) server, even if p4d is not being upgraded. The only exception to requiring downtime is if the current SDP is r2019.<em>x</em> <strong>and</strong> your SDP is <em>not</em> configured to use <code>systemd</code>, i.e. does not have <code>/etc/systemd/system/p4*.service</code> files. (Most 2019-2021 era SDP deployments use systemd, so this is a narrow exception.)</p>
</div>
<div class="paragraph">
<p>If the current SDP <strong>and</strong> P4D versions are both r2019.1 or later, the downtime can be brief. The scripts can be upgraded while the server is live, stopping p4d only long enough to change the <code>systemd *.service</code> files with new ones.</p>
</div>
<div class="paragraph">
<p>If your SDP is older than 2019.1, other changes will be needed depending on your SDP version, which will extend the downtime for p4d needed to upgrade the SDP. Read on to get a sense for what steps are required, which vary based on your SDP version.</p>
</div>
<div class="paragraph">
<p>If you are upgrading P4D along with the SDP, and your P4D version is older than 2019.1, live checkpoints are recommended after the upgrade is complete. This can significantly extend downtime required. The "to-or-thru P4D 2019.1" upgrades involve significant Helix Core database structural changes. If your Helix topology includes edge servers, you’ll want to account for taking checkpoints of the edge servers in "to-or-thru 2019.1" upgrade planning; edge checkpoints can occur in parallel with the checkpoint on the master server to reduce overall upgrade process duration.</p>
</div>
<div class="sidebarblock">
<div class="content">
<div class="title">Drivers of Downtime Duration</div>
<div class="paragraph">
<p>The big drivers of required downtime duration are:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Is SDP 2019.1+? If so, no SDP structural changes are needed, so less downtime is needed.</p>
</li>
<li>
<p>Is P4D being upgraded to-or-thru 2019.1? If yes, significantly longer downtime is needed, both for the p4d upgrade process and taking a live checkpoint after.</p>
</li>
<li>
<p>Time required to execute the SDP upgrade steps that you’ll define in detail with information from later in this document. The older the SDP version, the more steps required.</p>
</li>
<li>
<p>Sophisticated global topologies with many machines take longer for these one-time legacy upgrades, due to needing to run commands on multiple machines.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>Note that, once on the SDP 2020.1+ and using P4D 2019.1+, we do not expect any future upgrades to require extended downtime. Upgrade simplification and downtime reduction are priorities for both Helix Core and the SDP.</p>

</div>
</div>
<div class="sect2">
<h3 id="_sdp_machines_and_instances">2.3. SDP Machines and Instances</h3>
<div class="paragraph">
<p>Early in your planning, you’ll want to take stock of all server machines on which the SDP is to be upgraded.</p>
</div>
<div class="paragraph">
<p>For each machine, you’ll need to be aware of what SDP instances need to be upgraded on that machine.</p>
</div>
<div class="paragraph">
<p>For each instance on any given machine, determine what servers or services are in place. For example, a given machine might be a master p4d server for one instance, a replica for another, and a simple proxy for a third instance.</p>
</div>
</div>
<div class="sect2">
<h3 id="_mount_point_names">2.4. Mount Point Names</h3>
<div class="paragraph">
<p>You will need to be aware of the three standard SDP mount points. While referred to as "mount points" in this document, in any given installation, any or all of the three SDP mount points may be simple directories on the root storage volume, or symlinks to some other storage volume. In some installations, fewer than three volumes were used, and in some cases 4 were used (2 for metadata). In some cases the operating system root volume was used as one of the volumes. Investigate and be aware of how your installation was configured. Comparing the output of <code>pwd</code> and <code>pwd -P</code> in the same directory can be informative.</p>
</div>
<div class="paragraph">
<p>The mount points do not necessarily need to be changed during the SDP upgrade process, as the SDP structural design has always and remains flexible with respect to mount point names. However, understanding whether the "mount points" are actual mount points, regular directories or symlinks is something to be aware of for detailed planning.</p>
</div>
<div class="paragraph">
<p>In the examples below, the modern SDP mount point names are used:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><code>/hxdepots</code> - Volume for versioned files and rotated/numbered metadata journals.</p>
</li>
<li>
<p><code>/hxmetadata</code>- Volume for active and offline metadata. In some cases the single <code>/hxmetadata</code> is replaced with the pair <code>/hxmetadata1</code> and <code>/hxmetadata2</code>.</p>
</li>
<li>
<p><code>/hxlogs</code> - Volume for active journal and various logs.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>Depending on the version of the SDP, the above values may be used, or earlier defaults such as:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><code>/depotdata</code> for <code>/hxdepots</code></p>
</li>
<li>
<p><code>/metadata</code> for <code>/hxmetadata</code></p>
</li>
<li>
<p><code>/logs</code> for <code>/hxlogs</code>.</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>In some cases, custom values were used like <code>/p4depots</code>, <code>/p4db</code>, <code>/p4jnl</code>, etc. In these cases, it is important to know what standard names are referred to by the local names.</p>
</div>
<div class="paragraph">
<p>In the sample steps in this document, adapt the steps to use your local values for mount point names to the new values.</p>
</div>
<div class="paragraph">
<p>If your site uses two volumes for metadata, <code>/hxmetadata1</code> and <code>/hxmetadata2</code>, continue using those same names.</p>

DESCRIPTION:
This script obsoletes the SetDefaultDepotSpecMapField.py trigger.
It does so by following a series of steps. First, it ensures that
the configurable server.depot.root is set correctly, setting it
if it is not already set.
Next, the Triggers table is checked to ensure the call to the
SetDefaultDepotSpecMapField.py is not called; it is deleted from
the Triggers table if found.
Last, it resets the 'Map:' field of depot specs for depot
types where that is appropriate, setting it to the default value of
'<DepotName>/...', so that it honors the server.depot.root
configurable. This is done for depots of these types:
* stream
* local
* spec
* unload
* graph
but not these:
* archive
* remote
If an unknown depot type is encountered, the 'Map:' field is reset
as well if it is set.
This script does a preflight check first, reporting any cases
where the starting conditions are not as expected. These conditions
are treated as Errors, and will abort processing:
* Depot Map field set to something other than the default.
* Configurable server.depot.root is set, but to something other
than what it should be.
The following are treated as Warnings, and will be reported but
will not prevent processing.
* Configurable server.depot.root is already set.
* SetDefaultDepotSpecMapField.py not found in triggers.
* Depot already has 'Map:' field set to the default value:
<DepotName>/...
OPTIONS:
-v<n> Set verbosity 1-5 (-v1 = quiet, -v5 = highest).
-L <log>
Specify the path to a log file, or the special value 'off' to disable
logging. By default, all output (stdout and stderr) goes to
EDITME_DEFAULT_LOG
NOTE: This script is self-logging. That is, output displayed on the screen
is simultaneously captured in the log file. Do not run this script with
redirection operators like '> log' or '2>&1', and do not use 'tee.'
-p Run preflight checks only, and then stop. By default, actual changes
occur if preflight checks find no issues.
-n No-Op. No actions are taken that would affect data significantly;
instead commands are displayed rather than executed.
-D Set extreme debugging verbosity.
HELP OPTIONS:
-h Display short help message
-man Display man-style help message
-V Display version info for this script and its libraries.
EXAMPLES:
A typical flow for this script is to do a preflight first, and then
a live run, for any given instance:
clear_depot_Map_fields.sh -i 1 -p
clear_depot_Map_fields.sh -i 1
Note that if using '-n', the '-v5' flag should also be used.</code></pre>

<div class="paragraph">
<p>Modern SDP uses and requires <code>server.id</code> files in the \$P4ROOT directory. If your SDP does not have <code>server.id</code> files in the \$P4ROOT directory, you’ll need to add them before starting p4d after upgrading.</p>
</div>
<div class="paragraph">
<p>When upgrading the SDP, you may want to redo replica, replacing any existing replicas with new ones generated with the SPD <code>mkrep.sh</code> script, and ensuring the ServerID values follow the SDP Server Spec Naming Standard and replication best practices. See the <a href="SDP_Guide.Unix.html">SDP Guide (Unix)</a> to learn about using <code>mkrep.sh</code>.</p>
</div>
<div class="paragraph">
<p>If you do plan to do this, you may want to plan your overall upgrade procedure as follows:</p>

<li>
<p>Upgrade SDP (as detailed in this document).</p>

<p>Tackling the replication redo increases the benefit of the overall upgrade. However, if checkpoints take a long time in your environment, it also may significantly increase the required duration of the downtime in the maintenance window. This is due to the need for new checkpoints as needed during the replication recreation process. It is possible to defer replication upgrades to a separate maintenance operation.</p>

<p>With the familiarization and planning from the last section complete, move on to defining an upgrade procedure for your topology.</p>

<div class="paragraph">
<p>The procedure is broken into 3 phases:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><strong>Preparation</strong>: Preparation steps can be done in a non-disruptive manner on a production server ahead of the Execution, possibly days or more ahead of the target date for the actual upgrade.</p>
</li>
<li>
<p><strong>Execution</strong>: Execution steps are generally performed in a scheduled maintenance window.</p>
</li>
<li>
<p><strong>PostOp</strong>: PostOp steps are done some time after the upgrade is complete, perhaps days or weeks later. For example, some cleanup is done in PostOp. Often the upgrade procedure leaves copies of various files and directories around to support a fast abort of the upgrade. Such files are comforting to have around during the upgrade procedure, but after a time become clutter and should be removed.</p>
</li>

These procedure involves deploying new files on the Production server ahead of the actual upgrade.

The preparation steps can be safely done without affecting behavior until you are ready to execute the upgrade. However, human error is always a possibility when working on a production server.

<p>There are a variety of strategies for locking out users during maintenance. Choose what combination to apply in your environment.</p>
</div>
<div class="ulist">
<ul>
<li>
<p><strong>Protections table</strong>: Create a near-empty "maintenance mode" Protections table that references only the P4USER used by the SDP (typically <code>perforce</code>) and any replication service users (<code>svc_*</code>). As maintenance starts, save the standard Protections table, and put the maintenance one in place. At the end of maintenance, bring the original one back in place. (Be aware of whether your site has any polices or custom automation that might interfere with this method.)</p>
</li>
<li>
<p><strong>Temp Firewall Changes</strong>: Using network and/or host firewall rules can block end users out during maintenance. Be wary not to block replicas. (Warning: This can be complex and hard to get right, and may involve coordination with other teams if the Perforce admin does not have direct control over such things. Choose this option with care.)</p>
</li>
<li>
<p><strong>Temp P4PORT Change</strong>: In some environments, the P4PORT and P4BROKERPORT configured in the Instance Vars files are changed to non-production values not known to users during maintenance, and switched back when done. If there are replicas, there is a need to do <code>p4d -cset</code> commands to change replica’s P4TARGET back and forth between production and maintenance mode values.</p>
</li>
<li>
<p><strong>DFM Brokers</strong>: Down For Maintenance "(DFM)" brokers can be used for some types of upgrade. DFM brokers cannot be used if SDP structure change are needed, as all processes must be down in that case. The legacy upgrade procedure outlined in this document does not account for using DFM brokers, and for this particular upgrade we do not recommend using them. However, it is possible; see <a href="#_dfm_brokers_for_legacy_upgrade">Appendix 3.B, <em>DFM Brokers for Legacy Upgrade</em></a>.</p>

Make case-by-case decisions on what configurables you want, what values you want, and whether you want it to create <code>spec</code> and <code>unload</code> depots. If you already have such depots, remove the logic block that creates the new depots. Be sure to understand each line of the script, and ensure the logic and values set fit your environment.</p>

<h3 id="_dfm_brokers_for_legacy_upgrade">Appendix B: DFM Brokers for Legacy Upgrade</h3>
<div class="paragraph">
<p>If you desire to use DFM brokers for the legacy upgrade to SDP 2020.1 as outlined in this document, you cannot use the standard init scripts and procedures for managing the p4broker process, as those scripts and procedures will be disrupted during the upgrade process. Also, using a DFM broker will tie up the port number, creating a bit of complexity and interfering with scripts or procedures that start/stop the services. Care must be taken to avoid attempting to run the DFM broker during certain parts of the upgrade process.</p>
</div>
<div class="paragraph">
<p>With those caveats noted, if care is taken, it is possible to use a specially configured DFM broker for the legacy upgrade to SDP 2020.1. It can be done by making a copy of the new <code>p4broker</code> binary to some non-SDP-managed location (such as <code>/home/perforce</code>) and generating a disposable configuration file.</p>
</div>
<div class="paragraph">
<p>Here is a sample procedure to use a DFM broker. You will need to modify the sample configuration file to use the correct ports for your environment.</p>
</div>
<div class="literalblock">
<div class="content">
<pre>mkdir /home/perforce/dfm
cd /home/perforce/dfm
curl -s -O http://ftp.perforce.com/perforce/r23.1/bin.linux26x86_64/p4broker
chmod +x p4broker</pre>
</div>
</div>
<div class="paragraph">
<p>Here is a similar sample using a DFM broker on SSL:</p>
</div>
<div class="literalblock">
<div class="content">
<pre>mkdir /home/perforce/dfm
cd /home/perforce/dfm
curl -s -O http://ftp.perforce.com/perforce/r23.1/bin.linux26x86_64/p4broker
chmod +x p4broker
chmod 700 /home/perforce/dfm
export P4SSLDIR=/home/perforce/dfm
./p4broker -Gc</pre>
</div>
</div>
<div class="paragraph">
<p>Then, create a broker config file <code>/home/perforce/dfm/p4broker.cfg</code> with contents like this sample:</p>
</div>
<div class="listingblock">
<div class="content">
<pre class="highlight"><code> target = ssl:1666;
listen = ssl:1667;
directory = /home/perforce/dfm;
logfile = p4broker.dfm.log;
admin-email = null;
admin-phone = null;
admin-name = null;
command: .*
{
action = reject;
message = "\nPerforce Helix is Down for scheduled maintenance\n";
}</code></pre>
</div>
</div>
<div class="paragraph">
<p>The DFM broker can then be started with a simple command line like:</p>
</div>
<div class="literalblock">
<div class="content">
<pre>export P4SSLDIR=/home/perforce/dfm/p4broker
/home/perforce/dfm/p4broker -c /home/perforce/dfm/p4broker.cfg</pre>
</div>
</div>
<div class="paragraph">
<p>It can be stopped with a command like:</p>
</div>
<div class="literalblock">
<div class="content">
<pre>pkill -f /home/perforce/dfm/p4broker</pre>
</div>
</div>
<div class="paragraph">
<p>This stop command will stop only the DFM broker. (Note: The <code>-f</code> in that command is not "force", but rather "full regex matching"; see <code>man pgrep</code> for more information.)</p>
</div>
<div class="paragraph">
<p>In your planning, account for starting and stopping the DFM broker at times to avoid interfering with operations that start/stop services.</p>
</div>
<div class="paragraph">
<p>If you have multiple machines in your environment, copy the <code>/home/perforce/dfm</code> directory to all machines, and account for starting/stopping the DFM broker on all machines in your planning.</p>
</div>
</div>
<div class="sect2">
<h3 id="_upgrading_from_an_earlier_patch_of_sdp_2020_1">Appendix C: Upgrading from an earlier patch of SDP 2020.1</h3>
<div class="paragraph">
<p>If you are upgrading SDP from a prior patch of 2020.1, the procedure is the same as above, though most steps can be skipped (per details above). <strong>When upgrading from the 2020.1 GA release or any subsequent patch to the current latest patch, no Helix Core service downtime is required</strong>.</p>
</div>
<div class="paragraph">
<p>Note that customers upgrading from development DEV-PRE-RELEASE versions of SDP 2020.1 will require a small amount of downtime if the the systemd init mechanim is used, as the systemd *.services files will need to be updated.</p>

Refactored SDP Legacy Upgrade content into a separate doc. The SDP Guide will be remain comprehensive and cover how to upgrade the SDP itself forwardm from the current version (2020.1) using the new, p4d-like incremental upgrade mechanism. The content for manual upgrade procedures needed to get older SDP installations to 2020.1 is only useful until sites are on 2020.1. This content is extensive, narrowly focused, and of value only once per installation, and thus the legacy upgrade content is separated into its own document. Regenerated work-in-progress HTML files for easier review. |
