This is corrected such that PCM 0 is now reported for the upper-left PCM and PCM 1 for the lower-right PCM. Old port handle can cause SYSMGR to become unresponsive. Accessing the old port handles after a node reboot can cause the SYSMGR to become unresponsive. This is resolved by clearing the cached port handles. Check health speed is improved by not flagging PDs undergoing servicemag. Check health speed is improved by eliminating some slow checks when many PDs are in the servicing state. Unreliable connections between Peer Motion arrays An unreliable connections between a source and a could lead to host issues. destination array in a Peer Motion relationship could result in delays in responding to host requests for data. Duu to this the host marks the file systems as unavailable. This is resolved. Alerts from peer motion trial licenses. When the trial period for peer motion license that is included by default with new system licenses ends, alerts are generated about being in violation of the license agreement. These incorrect alerts are removed. Lack of updates in show commands. A rare issue where show commands does not reflect changes to volumes and other objects is prevented. Missing hosts and LUNs in show commands with very large number of unused hosts. If a large number of initiators, that are not part of any host definition, are visible to the system, show commands might miss some objects, typically hosts and LUNs. This is resolved. Admstat does not handle correctly the deleted VVs. Resolved an issue where the adminstat IOCTL command does not account for a VV being deleted in the middle of the IOCTL execution. Resolved an Issue reading the TOC after a conversion using the Keepvv option. The code that read the TOC assumed that base VVs always are entered before a snapshot. However, a conversion using the keepvv option transfers a snapshot to a different base VV. The code is updated so that the TOC can properly read the VVs in this scenario. Issuing a setvvset -name command might stop Issuing a setvvset -name command to modify the event logging mechanism. the name of an existing virtual volume set can result in the termination of em_filter process. The em_filter process is responsible for event logging and alert processing. The em_filter process is stopped till the individual node on which the setvvset -name command was issued is rebooted. Get LBA Status processing with Virtual Copy. On earlier versions of the HP 3PAR OS, processing of Get LBA Status SCSI commands to exported virtual copies may not complete, consuming excessive system resources. This is resolved and it ensures that these SCSI commands complete correctly. ExposePaths with multiple InitiatorPortIDs will now result in multiple SPC's. One of the solution for issue 84384 in the HP 3PAR OS 3.1.2 MU2 Release Notes is reverted. Calling ExposePaths with multiple InitiatorPortIDs now results in multiple SPC's, same bevahavior before HP 3PAR OS 3.1.2 MU2 is retained. 54 HP 3PAR OS 3.1.2 MU3 Release Notes
