HP 3PAR Upgrade Pre-Planning Guide

• HP 3PAR software applications running on the HP 3PAR StoreServ Storage must be shut down.
• Ensure that no HP 3PAR Virtual Copy promotes are in progress. To confirm, check that no
volumes are in the started, cpp state. If any promotes are in progress, wait until the
promote finishes to begin the online upgrade.
HP 3PAR Remote Copy Guidelines
When planning HP 3PAR OS upgrades where HP 3PAR Remote Copy software is configured, the
following rules apply:
• Because it may not be feasible to upgrade all storage systems participating in the HP 3PAR
Remote Copy configuration at the same time, the allowed delta between major versions of
the HP 3PAR OS release is limited to adjacent major release levels—for instance, from HP
3PAR OS 3.1.2 to 3.1.3. All maintenance update (MU) levels are considered to be in the
same major OS version. Examples:
◦ A delta of HP 3PAR OS versions 2.3.1 and 3.1.1 is supported for a period of 5 weeks.
◦ Conversely, an upgrade from HP 3PAR OS 3.1.1 to HP 3PAR OS 3.1.3 GA is not
supported, because these are not adjacent major HP 3PAR OS versions.
• All HP 3PAR StoreServ Storage systems in the HP 3PAR Remote Copy configuration must be
upgraded to the same major OS version within a 5-week period.
WARNING! For HP 3PAR StoreServ Storage systems licensed with HP 3PAR Remote Copy, direct
upgrade is not supported from 2.2.4 to 3.1.1 or later. See Table 6 (page 14)
• For systems running HP 3PAR OS 2.2.4 or later with HP 3PAR Remote Copy, only the groups
need to be stopped. Stop the remote copy groups after the synchronization has completed
via stoprcopygroup group name/s.
For details about using the stoprcopygroup command, see the HP 3PAR Remote Copy
User Guide. To obtain this document, see the HP SC website:

• HP 3PAR OS 2.2.4 systems with HP 3PAR Remote Copy cannot be upgraded directly to HP
3PAR OS 3.1.1 and later. HP 3PAR OS 2.2.4 systems with HP 3PAR Remote Copy must be
upgraded to HP 3PAR OS 2.3.1 MU5 before an upgrade to HP 3PAR OS 3.1.3. (including
offline upgrades).
• When an upgrade to HP 3PAR OS 3.1.1 is performed, HP 3PAR Remote Copy Ethernet ports
must be set to autonegotiate. If they were changed to 100 Mbs full duplex, the links may
not start The autonegotiate setting can be changed in advance of a software upgrade by
issuing the following command:
# controlport rcip speed auto <value> <n:s:p>
This should be performed on one remote-copy link at a time, making sure to check that the
link is working before setting the other link to autonegotiate.
