HP Integrity Virtual Machines Version 4.2 Release Notes

8.2.17 AVIO Limitations
The following sections describe the current limitations using AVIO.
8.2.17.1 Modifying the Storage Adapter from scsi to avio_stor
If you attempt to modify a storage adapter from scsi to avio_stor on a port for a running
guest, the hpvmmodify command allows the change, but the change lasts only until the next
guest startup. In addition, the hpvmnet command displays incorrect port information for the
currently running guest until the guest is stopped and restarted.
8.2.17.2 GuestAVIOStor Bundle not Installed but AVIO Storage Device is Configured
If the GuestAVIOStor bundle is not installed on the HP-UX guest, any configured AVIO Stor
HBAs will not be claimed in the guest, and the LUNs configured under the AVIO Stor HBAs
will not be accessible. If the LUN is a boot disk, boot will fail with a panic indicating missing
drivers.
8.2.17.3 Longer Failure Reporting Time for AVIO Devices on 11i v2 Guests
If a backing store is not responsive due to device errors, it might take up to 30 seconds on an
HP-UX 11i v2 guest to report a failure. For example, the diskinfo command might fail after
30 seconds:
# timex diskinfo /dev/rsdk/c1t14d0:
diskinfo: can't open /dev/rdsk/c1tl4d0: No such device or address
real 0m30.26s
user 0m0.00s
sys 0m0.01s
This delay is caused by the retry of failed commands from the nonresponding backing store.
There is currently no workaround.
8.2.17.4 Online Modification of AVIO Devices Might Fail
Devices configured under AVIO Stor HBA for a guest cannot be deleted (using the hpvmmodify
command) if the guest is at EFI.
Stop the guest using the hpvmstop command and retry the hpvmmodify command.
Devices configured under AVIO Stor HBA for an HP-UX 11i v3 guest cannot be deleted (using
the hpvmmodify command) if the guest is online.
Run ioscan -kfNC tgtpath or ioscan -kfNC lunpath from the guest to obtain the
tgtpath or lunpath H/W Path for the device to be deleted. Remove the device by using rmsf
-H of the lunpath or tgtpath H/W Path from the guest and retry the hpvmmodify command
from the host.
8.2.17.5 Mapping AVIO Storage Devices on HP-UX Guests
This section explains how to map an AVIO storage device on an HP-UX guest to an hpvmstatus
display on the Integrity VM Host either at the EFI console or at the HP-UX operating system.
The following example shows the output of hpvmstatus from the Integrity VM Host:
# hpvmstatus -P aviotest
