11.5 HP StoreVirtual Storage Release Notes

• For a Fibre Channel volume, the Performance Monitor reports 0.0 for the first volume statistics
when a second volume is created and mounted on the same server
This happens because the path of first volume gets changed when the second volume is mounted,
so the Performance Monitor displays 0.0 for the older path. To solve this issue, remove the older
path and add the new path of the first volume to see the correct performance values.
• Windows Server 2012 Hyper-V cluster shows disk errors on the active node during scheduled
application-managed snapshots when using Fibre Channel
The snapshot process quiesces the volume, then takes the snapshot, then mounts the snapshot
using Fibre Channel, then unmounts the snapshot. Unmounting the snapshot breaks the Fibre
Channel connection, and this sometimes generates MPIO and disk errors in the Windows Event
log. You can ignore these errors. The snapshot completed successfully.
Hardware and platforms
• RAID 6 contains a single array when using 4 TB drives in the HP StoreVirtual 4530
All HP StoreVirtual 4530 storage systems with 4 TB drives ship with RAID 6 configured as a single
12–drive array. If more than two drives fail at the same time, the storage system must be re-imaged.
• Online upgrade to Version 11.x fails on a 32-bit Failover Manager
Older versions of the Failover Manager for VMware, such as Version 8.5 or 9.0, or a Version
9.5 Failover Manager for Microsoft Hyper-V, are 32-bit and no longer supported. To resolve this
issue, remove the older version of the Failover Manager and install the 11.x version from the HP
StoreVirtual Virtual Storage Appliance (VSA) DVD or .iso image.
• Drive status may be reported differently in the CMC and iLO if a drive is not properly seated or
is running an older version of firmware
CMC shows drive status as Active, while the same drive status in the iLO→information→System
Information→storage tab is reported as Degraded.
Try the following actions to resolve this issue:
◦ Reseat the problem drive.
◦ If the issue still exists, reboot the storage system after reseating the drive.
◦ If the drive is running older firmware, update the drive firmware.
◦ If iLO still shows the drive status Degraded, then replace the drive.
• In the HP StoreVirtual 4730, when two drives are unavailable and the hot spare is rebuilding, the
Device status is not reported properly on the RAID Setup tab in the CMC
The status remains at 0% estimating. However, you can see the updated RAID rebuilding
status, with the percentage completed and estimated time remaining, on the storage system
Hardware Information tab.
• Failed drive status in HP StoreVirtual 4730 shows as Hot spare down,Off or removed
When a drive is removed in an HP StoreVirtual 4730, that drive status is incorrectly reported as
Hot spare down,Off or removed. However, the hot spare drive status is either active or
rebuilding against the failed drive at that point in time. The removed drive is the only drive that
is off or removed.
• A P4900 G2 controller firmware mismatch event does not generate an SNMP trap
If the P410 controllers in a P4900 G2 storage system have different firmware versions, the firmware
version mismatch generates an event. However, that event does not generate an SNMP trap. This
situation could occur if a controller is replaced in a storage system and the replacement controller
is at a different firmware version.
