HP 3PAR OS 3.1.2 MU5 Release Notes

DescriptionItemIssue ID
while the system is powered-down, the alert still
exists upon reboot. The alert is not cleared.
The SCSI subsystem is not handling busy errors
from the Volume Layer correctly and it can result
Resolved AIX SCSI command timeouts on VV
busy errors

in SCSI commands being timed out for AIX (NACA
supported) hosts. AIX issues an ABORT when the
command timeout occurs and then retry the
command. To resolve this, return the BUSY status
back to AIX so that AIX does not issue an ABORT
prior to retrying the command.

The CLI client version on the SP is 3.1.2.278
instead of 3.1.2.422 as with other components.
CLI Client 3.1.2.278 Support89948
This is expected. These CLI client versions are
essentially the same. CLI client version 3.1.2.278
supports all connections on the storage system to
the CLI server from version 3.1.x to 3.1.2 MU2.
Known Issues with the OS
Cannot downgrade from 3.1.2.422 (MU2) to an earlier release on specific storage
systems (Bug 86680)
Downgrading from HP 3PAR OS 3.1.2 MU2 to an earlier release is not possible on the 10000
and 7000 storage systems if the Virtual Volume IDs (VVIDs) exceed the earlier OS release’s limit.
The 3.1.2 MU2 version supports up to 32K OpenVMS VVIDs and the 3.1.2 MU1 and earlier
releases support up to 12K VVIDs on the 10000 system and 8K VVIDs on the 7000 system. When
downgrading from 3.1.2 MU2 to 3.1.2 MU1 or earlier releases, the VVID must be within the
previously supported range for the system.
A message similar to this appeas if VVIDs exceed the supported limit:
One or more vv’s exist with an id greater than 12287. This not supported
by the target update version. Remove vv’s with an id greater than 12287
and try again.
Workaround: If the number of VVIDs is greater than 12K on the 10000 system and 8K on the
7000 system, reduce the number of VVIDs to less than the number supported and retry the
downgrade.
CAUTION: After the new features of HP 3PAR OS 3.1.2 MU2 are used, downgrading to an
earlier version may not be possible.
Kernel Core when performing online upgrade from 3.1.2.322 MU1 to 3.1.2.412
(Bug 89407)
During an online upgrade from HP 3PAR OS 3.1.2.322 (MU1) to HP 3PAR OS 3.1.2.422 (MU2),
a node running HP 3PAR OS 3.1.2.422 (MU2) causes data unavailability when rcopy transaction
log is converted to the new format.
