Issue ID Item Description 62000 setvv -snp_cpg behavior with shared logical disks corrected Using setvv -snp_cpg on virtual volumes relying on shared logical disks was causing a panic of the system manager. The behavior of setvv has been corrected: now all the virtual volumes sharing logical disks must be specified as arguments, otherwise the command will fail. 62135 Disk replacement now better handles In prior releases SP, if one prematurely exited the GM script premature closing replacement, the scripts may misinterpret 'abandoned' files with state information. This is corrected in SP 2.5.1. 62212 Host ID shown in the CLI command showhost -agentis incorrect. Host ID shown in the CLI command showhost -agent is incorrectly showing the internally generated host ID from the HP 3PAR system and not the one reported by the Host Explorer running on the host. Workaround is to consult the Host Explorer for the ID. 62564 Do not use the SCSI-2 reservation lock when servicing the MCLP_SCSI2_SHOW mcall showrsv and the IMC retrieving reservation info will no longer cause a long block of being able to run other commands. 63214 Multiple tpds_scsi_thread eventlog entries 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. 63307 (also 43798) Improve detection of HBA mailbox timeouts Under heavy CPU load, sometimes HBA mailbox commands are incorrectly deemed timed out, resulting in the driver taking a firmware core dump and resetting the HBA. The driver has been modified to avoid incorrectly treating mailbox commands as timed out. 64109 On rare occasions a link down event The underlying behavior that led to this potential instability has been on a Remote Copy IP link can lead identified and corrected. to system unavailability 64138 Record Timing Information for Reservations System Manager has been updated to track the time taken to process SCSI-II and SCSI-3 reservation requests and to log any abnormally high processing times. Slow processing of reservation requests has been seen on heavily-loaded customer systems and the additional diagnostic information will help to identify this condition. 64497 Issue Capacity Change Notification Issue 'CAPACITY DATA HAS CHANGED' SCSI Unit Attention to hosts to HP-UX hosts which use the HP-UX host persona on VV grow. This will allow recent versions of HP-UX to detect volume resize automatically. 64814 Issuing startrcopy -nosync To avoid the system potentially going offline during a Remote Copy when a group is already resync operation, the startrcopygroup -nosync will started may lead to the system going now return a failure in 2.3.1.MU5 if RC group is already started. offline 64924 System Reporter and Adaptive Optimization Functionality System Reporter and Adaptive Optimization functionality has been added into HP 3PAR OS. 65389 Rate Limit LUNs Changed Notifications Limit the rate at which REPORTED LUNS DATA HAS CHANGED Unit Attentions are raised to a SCSI initiator. 65460 Memory leak if vv block failure occurs When setting up a virtual volume block, we allocate some memory upfront. If the virtual volume block fails, we may not free this memory which can cause a memory leak. To resolve this issue the allocated memory is now released upon virtual volume block failure. 65463 On rare occasions bad RTC battery Bad RTC battery on master node can cause system's time to set in sets PR failure timestamp way in distant past or future. That, in turn, causes battery's charge level to future ultimately degrading BBU drop to 0% due to bug in battery manager (a thread of sysmgr). It (Battery Backup Unit) charge level to also prevents battery's charge level to improve. Hence, with 0% cache 0% and preventing same from system goes in to write-through mode with 0% cache. improving We have fixed the bug in 2.3.1.MU5 which was also propagated to all the later releases. The fix makes sure that system-time is always 10 HP 3PAR OS 3.1.2 GA Release Notes
