1 HP 3PAR OS 3.1.2 GA Release Notes Online Upgrade Considerations This feature allows the upgrade of the OS concurrently with I/O activity on the attached hosts, provided certain conditions are met. For further information and pre-planning of online upgrades, refer to the latest version of the HP 3PAR OS Upgrade Pre-Planning Guide. To obtain a copy of this documentation, go to http://www.hp.com/3par/support_manuals, select your product, and then click Manuals. WARNING! Beginning with HP 3PAR OS 3.1.
What’s New in the OS HP 3PAR OS 3.1.2 enables customers to increase multi-tenant consolidation on shared infrastructure and increase agility and efficiency with several new features and enhancements. HP 3PAR OS 3.1.2 supports the new HP 3PAR StoreServ 7000 Storage. HP 3PAR OS 3.1.
Autonomic Management for Agility and Ease of Use • HP 3PAR Adaptive Optimization software has been enhanced to support all manageability and configuration using HP 3PAR management console and CLI. The data for AO is now maintained on the StoreServ Storage in an internal database. • Autonomic Rebalance capability is now available as part of the HP 3PAR OS.
Other Enhancements • Provides the ability to force the shutdown of the HP 3PAR StoreServ Storage node for maintenance if there are active tasks running without having to manually stop all the tasks before shutting down the node for maintenance. HP 3PAR Remote Copy software now leverages the HP 3PAR Thin Built-In ASIC to detect and eliminate the remote replication of zero pages during initial synchronization and ongoing synchronous replication.
Issue ID Item Description 54956 2.3.1 MU1: sysmgr panicked, system When resynchronizing a volume over 2TB in size to a rcopy secondary pending pfail recovery system, a 32bit counter used to represent the number of contiguous blocks which has ""delta"" data since the last resync may overflow. HP 3PAR OS has since been enhanced to use 64bit counters.
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.
Issue ID Item Description coherent and let the battery charge level to set to normal. On releases before 2.3.1.MU5, there's no workaround that would fix the problem without interrupting system. On such system, the only way to get the system to work normally is to restart sysmgr.
Issue ID Item Description switches, show fcns database detail will display this information. HP's SAN Visibility software will key off this information. 12 65930 Improve peer motion performance for full VVs Earlier full VVs used to be in writethru during import, and this impacted the VV performance as more regions are moved to local LDs over time. Now full VV and TPVV volumes are imported in the same way and the local LDs are no longer in writethru.
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.
Issue ID Item 70797 VV state returns to "normal" if a tune In previous HP 3PAR releases, when a VV tune is cancelled the is cancelled displayed VV state remained at ""tuning"" indicating that the tune must be completed (re-run) or rolled back in order to return the VV state to normal. This behavior changes in 3.1.2 as the VV state returns to ""normal immediately on task cancellation.
Issue ID Item Description device entry, thus the follow-up operations (e.g. LOGO) caused a host being wrongly disconnected. 78498 Sysmgr Unresponsive Fixed a defect in the sysmgr subsystem that could cause the sysmgr to be unresponsive and for host io to be blocked. Operations involving a region move (such as tunes) or a node integration could get the sysmgr into this state. Fixed the race condition between the sysmgr and kernel that caused this behavior.
Issue ID Item Description 68387 CLI command controlport rst Using CLI command controlport rst -l on a 10G iSCSI port -l can lead to fatal PCI errors under heavy host I/O can lead to fatal PCI errors and a subsequent node reboot. 68839 User guide edits Need to remove references to the MENU Driven Application from the UG if it is deprecated. 68840 Menu Driven Application deprecated Need to update RMO 4.
Issue ID Item Description The only impact this has is the suspension of periodic resyncs for the duration of the online upgrade. 81222 eventlog: Critical Cluster thermal shutdown seen during soft reset of DCN1 cages After a soft reset of the DCN1 cage's controllers, we noticed the following events being generated. 2012-10-26 09:27:41 PDT 0 Critical Cluster thermal shutdown hw_node:0 Node 0 We have not noticed any issues caused by the generation of this event.
Improving the transition time in a future release is planned. • Solaris 11 with Brocade Fabric Occasionally, Solaris hosts that are attached through a Brocade fabric lose paths after a failover or failback. In this case the host seems to have a problem with multiple FC_IDs referenced in the RSCN payload from the switch. This is an intermittent issue seen about 10% of the time. Ultimately the fix for this needs to be done on the host and is currently being investigated. • RHEL 6.
2 HP 3PAR OS CLI Release Notes Installation Notes for the OS CLI Virus Checking Virus checking is known to slow down and potentially cause issues with installation of the OS CLI.
