HP 3PAR InForm OS 3.1.1 MU1 Release Notes

DescriptionItemBug ID
Corrected signed/unsigned 32–bit overflow issue so that R5 logical disks
are now correctly checked regardless of size.

Fixed an issue in which a Node down SNMP trap is not generated if the
node with the active Ethernet connection was forcefully removed.

If a compactcpg operation results in truncating logical disks and the current
logical disk backup node fails during this operation, then the node taking

over as the logical disk backup (if there is one) will also fault, resulting in
a double node failure. This condition has been fixed by making the kernel
logical disk truncate code handle the case where the backup node is newly
assigned and not fully initialized by the system manager node down
processing.
When enumerating TPD_MemberOfStorageHardwareIDCollectionProvider,
a property string object might have a null pointer. This could cause a segfault
after being passed to underlying functions. This has been fixed.
Null pointer results in a
cimserver process failure.

On large systems, the system manager node initialization process to deliver
the physical disk, logical disk, and virtual volume information into the kernel

too lengthy.

was taking too long. This was due to the creation of Linux device entries
for each of these devices. Because these are used only for internal system
access, pushing this task to a background thread fixes this issue.
There was a potential node down issue in the R6 CRC regenerate and
re-write processing when this action occurs as part of a R6 chunklet
relocation. This issue has been resolved.

The Link Power Down event needs to be cleared to avoid node being put
in degraded state after node rejoins.

When a CPG fails to grow, an alert is issued. Previously, there was an issue
in which if the CPG could grow at a later time, the alert was not cleared
correctly. This issue has been resolved.

It was possible to exceed the maximum number of exported LUNs allowed
(16383) by extending a previously-exported VV set. Checks have been
added to ensure that this is not allowed.

a limit on memory usage when deleting snapshots.

Contact the switch vendor for help to configure the fill word. On Brocade
switches, the command to configure the fill word is portcfgfillword.
Fixed IO write credit pages merge code path, so that when LDIO flusher
flushes dirty cache pages to back end, it leaves the dirty mask in the log
entry for those credit pages in a consistent state.

A rare race condition existed in which cancelling inter-process messages
to avoid old message references were not being cleared. This has been
resolved.

The performance of SCSI-3 reservation handling has been improved,
preventing issues in which the storage system would be unable to keep up
with host requests.

In rare cases, InForm OS could process invalid intra-cluster messages due
to a hardware timing issue on T and F-series storage systems. InFormOS

has been enhanced to detect this situation and re-read the data to ensure
only messages with correct contents are processed.
