HP 3PAR OS 3.1.2 MU5 Release Notes

DescriptionItemIssue ID
Using setvv -snp_cpg on virtual volumes relying on shared logical
disks was causing a panic of the system manager. The behavior of
setvv -snp_cpg behavior with
shared logical disks corrected

setvv has been corrected: now all the virtual volumes sharing logical
disks must be specified as arguments, otherwise the command will
fail.
In prior releases SP, if one prematurely exited the GM script
replacement, the scripts may misinterpret 'abandoned' files with state
information. This is corrected in SP 2.5.1.
Disk replacement now better handles
premature closing

Incorrect reference counting in earlier versions of HP 3PAR OS may
lead to a large number of debug eventlog entries of the form

"tpds_scsi_thread 4816921 secs lapsed on entry: " on host deletion.
This issue has had no other observed impact and the reference
counting has been corrected in HP 3PAR OS 3.1.2.
Under heavy CPU load, sometimes HBA mailbox commands are
incorrectly deemed timed out, resulting in the driver taking a firmware

avoid incorrectly treating mailbox commands as timed out.
The underlying behavior that led to this potential instability has been
identified and corrected.

been seen on heavily-loaded customer systems and the additional
diagnostic information will help to identify this condition.

To avoid the system potentially going offline during a Remote Copy
resync operation, the startrcopygroup -nosync <grp> will
now return a failure in 2.3.1.MU5 if RC group is already started.
Issuing startrcopy -nosync

When setting up a virtual volume block, we allocate some memory
upfront. If the virtual volume block fails, we may not free this memory
