Issue ID 79816 80497 80779 81188 81544 81722 81851 81891 81905 82092 Item Description (VolSetAddr). When the Lun0SCC capability applies, LUN0 should not be used as a name for a storage LUN. EVA to 3PAR Online Migration tasks could fail if EVA to 3PAR Online Migration tasks could fail if the EVA the EVA is under load, and require restarting. is under load, and require restarting. Changes are made to improve the StoreServ's ability to deal with longer response times from the EVA during the importing phase. SCSI commands not terminating properly. This addresses issues of not terminating SCSI commands properly when those commands could not be completed by the InServ. Some commands require the use of SYSMGR. When the SYSMGR is not available to help process the commands, the commands are not terminated and the commands are stuck in the queue of the host InServ ports. Active volume removals prevents periodic synchronizations starting for volumes within the same volume family. When active volume removal is in progress, the periodic synchronization process for volumes within the same volume family does not start. An error message is displayed indicating that the volume is locked. After the volume removal is completed, the next periodic synchronization process will begin. Periodic synchronizations may suspend during an online upgrade. During an online upgrade, periodic remote copy groups may stop synchronizing. If this occurs, normal operation will resume as soon as the upgrade is completed (after the cli upgradesys -finish command is executed). There is no need to stop periodic groups before the upgrade is carried out. Synchronous Remote Copy groups are unaffected. I/O to volumes in remote copy groups is unaffected. No manual intervention is required to Remote Copy groups or volumes before, during, or after the upgrade. The only impact of this issue is the suspension of periodic synchronization process for the duration of the online upgrade. Part number and model information displayed incorrectly for DCS1, DCS2, and DCN1 cage types. Due to an issue in the routine which gathers manufacturing record from EEPROMs in the DCS1, DCS2, and DCN1 cage types, part number and model information is incorrectly displayed. This issue is resolved. Use of setaocfg command causes the SYSMGR Use of the setaocfg command to swap and change application to become unusable. tier CPGs may cause the System Management application (SYSMGR) to become unusable. This issue is resolved. Improvement to RAID-1 large block sequential write performance. The inconsistent data flusher tries to flush data in full-stripe more aggressively. This helps to decrease number of IO requests issued to physical disks, thus reducing the load on physical disks. A node down event during EVA Online Import from a heavily loaded source array could cause a transient SCSI level error to be returned to the host. A node down event during EVA Online Import from a heavily loaded source array could cause a transient SCSI level error to be returned to the host. This is resolved. Now, the destination array locally retries the commands that fail in this way, rather than presenting the error to the host for retrying. A race condition that occurs during a node integration into the cluster and which causes SYSMGR to become unresponsive and data services to become unavailable. A race condition that occurs during a node integration into the cluster and which causes SYSMGR to become unresponsive and data services to become unavailable. This issue is resolved now.
