11.5 HP StoreVirtual Storage Release Notes

• Set boot from SAN using the Emulex HBA
To use boot from SAN with the Emulex HBA, use Emulex OneCommand and set the boot LUN to
5.
• Windows 2008 and Windows 2008 R2 require hot fixes to avoid volume availability issues when
using Fibre Channel
Transient errors may cause issues whereby an MPIO disk device could incorrectly be removed
from the host after a short duration Fibre Channel link failure. This can result in data unavailability
issues and possibly data loss issues. To resolve these issues, perform the following steps:
1. Install the hotfix listed in http://support.microsoft.com/kb/2460971.
HP recommends rebooting the server before installing 2522766.
2. Install the hotfix listed in http://support.microsoft.com/kb/2522766.
There is also another hotfix available for Microsoft cluster services that can supersede KB 2522766.
This hotfix addresses an issue in Microsoft clusters where a cluster resource could unexpectedly
end up in redirected state. This hotfix is not recommended unless you experience an issue similar
to what is outlined in the article found at http://support.microsoft.com/kb/2718576.
• 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.
