Online Upgrade Considerations
This feature allows the upgrade of the OS concurrently with I/O activity on the attached hosts,
provided certain conditions are met. For further information and pre-planning of online upgrades,
refer to the latest version of the HP 3PAR OS Upgrade Pre-Planning Guide. To obtain a copy of
this documentation, go to http://www.hp.com/3par/support_manuals, select your product, and

NOTE: Direct upgrades from 3.1.1.226 to 3.1.2.322 are not supported with this release of HP
3PAR OS 3.1.2, but are expected to be supported at a future date.
Customers running 3.1.1 and wishing to upgrade to 3.1.2 will need to upgrade to the 3.1.1 MU
prior to upgrading to 3.1.2.

What's New in the HP 3PAR OS
HP 3PAR OS 3.1.2 MU1 provides support for Linux and VMWare ESX version 4 and 5 with EVA
online Import.
NOTE: Starting from HP 3PAR OS 3.1.2, the HP 3PAR OS installation and admit hardware
process does not automatically create a RAID 5 Fiber Channel CPG. RAID 5 for both HP 3PAR
Fiber Channel and SAS (10K/15K) drives is fully supported on any class of HP 3PAR array. The
creation and modification of RAID 5 on NL drives is disabled via a system parameter:
AllowR5OnNLDrives. This system parameter can be modified via the setsys command to
enable support for RAID 5 on NL drives. If this parameter is disabled, new RAID 5 CPGs cannot
be created or modified on NL drives. If this parameter is enabled, RAID 5 CPGs can be created
or modified on NL drives.
HP strongly recommends RAID 6 for high capacity NL drives. HP has no RAID level recommendation
for non-NL drives, but the use of RAID 6 is a higher availability selection.
