HP 3PAR StoreServ 7400 2-node HP 3PAR OS 3.1.2 Release Notes - Page 13

Issue ID Item Description to facilitate expedited synchronization post migration. This functionality was integrated into the createsv command, using the -rcopy switch. 67556 Help for createsv CLI command does createsv now alows read-write snapshot creation from read-write not reflect changes to functionality base/read-write snapshots 67913 Firmware issue could cause port resets due to mailbox command timeouts Upgraded 1G iSCSI firmware to version 3.0.1.67 in order to address a firmware issue which could cause port resets due to mailbox command timeouts under heavy I/O load. 67983 Secondary iSNS address removed Secondary iSNS address has been removed from CLI since it was from CLI never supported. 68750 tunesys - added support for AO volumes The system tuning command tunsys now supports Adavtive Optimisation (AO) configured volumes split between CPGs. 68952 New alert if a 1G iSCSI port comes up at a lower speed If a 1G iSCSI port on the array comes up at a negotiated port rate that is lower than the expected 1G rate, an alert is generated. The showport -iscsi command now displays the actual rate; previous releases used to display 1Gbps regardless of the actual rate the link came up at. 69011 Fixed manual 8Gps rate setting for RCFC & PEER ports This release fixes the controlport rate command to allow for a manual rate setting of 8Gps on rcfc and peer ports that are capable of that data rate. Previously only the rate setting of 'auto', which is the default, would achieve a 8Gps rate for those ports. 69130 Cage Inaccessible errors after master Misleading alerts indicating that a cage is inaccessible, are no longer node/sysmgr panic emitted at the time of System Manager startup. 69193 Fibre Channel driver issue Fixed a driver bug that could cause a link list break in a very rare condition. 69439 Deprecate updatevv's -anyid option The updatevv -anyid option is deprecated. In 3.1.2 we changed the volume and snapshot removal handling in System Manager. When a volume or snapshot is removed, it is not cleaned up immediately. It remains hidden until a background thread recycles the resource. That means upon removal, the id of the volume is still being occupied, so updatevv may fail. In 3.1.2, we are using a different volume id but keep the same WWN when the snapshot is updated. Now updatevv calls a modified creategroupsv command which will always use the same WWN to create the new snapshot. 69556 Promote XR3B drive FW for Moose drives The XR3B firmware will lower a temperature threshold. The patch will modify the firmware database to cause the required firmware on Moose drives to be XR3B. SN: P90 will modify the scsidb to point the current firmware for Moose to be XR3B. As this is a scripted modification the scsidb it will need to be applied after every upgrade, before admithw is run. 69606 Pinned data after growing a VV part In cases where NL drives are overloaded in the extreme, upper layers of a RC group can see this as loss of access. If multiple NL drives are in this state, this loss of access can result in volumes going into preserved state. Along with other fixes to prevent this type of overloading (as in 77976) we also now allow longer NL access times and ensure multiple retries to ensure what looks like loss of access is actually so. 70121 Network issue when node is added/removed If a network message is sent to a node that then is removed from the system, the networking infrastructure hangs. Any future network issue cannot be handled, ultimately resulting in connectivity loss to the cluster until the network interface is restarted. A fix was made so that the network interface does not hang in this situation but eventually times out instead, allowing handling of other networking changes. 70425 Improved UNMAP performance Unmap SCSI commands issued to already-unmapped logical block address ranges of thinly-provisioned volumes are handled more efficiently in HP 3PAR OS 3.1.2. This can lead to improved performance during formatting operations for some host types. Modifications to the OS 13
