HP Storage Platform 2.0 Release Notes

Implementation Changes in HPSP Release 2.0
Hardware Monitoring
The following section describes implementation changes to hardware monitoring that were made
in HPSP Release 2.0:
• All of the logical (volumes) and physical (controllers, ports, drive enclosures, drives, etc.) objects
that are under the control of a storage controller or pair of storage controllers are grouped
together within a new logical STORAGE_CLUSTER component in the storage health report to
depict their relationship in the storage topology.
• On the Ibrix 9320 Storage Platform the HA_STORAGE health monitoring category has been
replaced with the new STORAGE_CLUSTER category for monitoring couplet visible storage. The
HA_STORAGE category is still supported but is being deprecated in the next release.
• A subset of all visible storage clusters can be monitored by specifying a list of storage cluster
UUIDs on the hpspmon command line. Prior to this change all storage clusters would have been
monitored.
Fixes
Firmware
The following firmware issues have been resolved:
• On the Ibrix 9730 Storage Platform, storage could become unresponsive when multiple surface
scans were launched on a single physical disk. Interaction between background surface scans
and performance has been significantly improved.
• On the Ibrix 9730 Storage Platform the controller caching policy has been adjusted to
significantly reduce the occurrence of command timeouts and aborts when running heavy
workloads with small block sizes.
• On the Ibrix 9730 Storage Platform, drive LEDs could go dark when an MDS600 storage
enclosure IO module was removed. Drive LEDs are now refreshed in this scenario.
• On the Ibrix 9730 Storage Platform, sometimes MDS600 storage enclosure IO modules were not
visible to the storage controllers after a FW flash of the IO module. This has been corrected.
• On the Ibrix 9730 Storage Platform, improved resilience against SAS topology disruptions due to
events such as booting of blades, which could lead to missing paths to storage.
Firmware management tool
See the HP HPSP_FMT User Guide, SAW document number c03598024-1. This new document
has disclosure level of HP and Customer Viewable so that services may share its contents with
customers having specific problems that can sometimes be resolved with this manual tool. In the
future, the document will be recast into a customer document and published on HP.COM.
Hardware Monitoring
The following hardware monitoring issues have been resolved:
• MDS600 and D6000 drive enclosure drawers are now reported by number: Drawer 1 for the
front-facing left drawer and Drawer 2 for the front-facing right drawer.
