Array I/O can halt after a power cycle with an HP-UX host
I/O halts after power cycling an HSV300-S enclosure connected to an HP-UX 11.23 host with HP-UX
driver versions earlier than B.11.23.08.02. To resolve this issue, either upgrade to version
B.11.23.08.02, or reset the HBAs on any server affected after an HSV300-S is power cycled.
Reboot can be required after EVA power cycle to resume access to LUNs
If an EVA4400 experiences a power cycle while the management GUI for Windows MPIO DSM is
open, the LUNs might not appear under Disk Management after they recover. This issue is seen when
the MPIO DSM Manager snap-in is open at the time of a power cycle. To reduce the probability of
this occurring, HP recommends that you close the GUI when you are not performing management
actions. HP is working to resolve this issue with the Windows MPIO DSM Manager software.
If this problem occurs, follow these steps:
1. Close the HP MPIO DSM Manager GUI.
2. Close Disk Management.
3. Stop and restart the Virtual Disk services.
4. Open Disk Management, and then rescan or Diskpart rescan to enumerate the LUNs.
If these steps are not successful, reboot the server.
