HP Integrity Virtual Machines 4.2.5: Release Notes

• You cannot upload or download firmware for emulated devices.
• Although HP-UX commands such as mptutil(1M) and mptconfig(1M) do not fail when run in
a guest, they do not always return the same information as they would when referencing a
physical device.
• The EFI drvcfg command does not fail when run in a guest, but it returns no useful data.
8.2.20 AVIO Limitations
The following sections describe the current limitations using AVIO.
8.2.20.1 iSCSI-Based Backing Stores Not Supported with Physical Volumes Under Certain
Circumstances
iSCSI-based backing stores are not supported with a physical volume under a logical volume that
is then exposed to guests as a virtual disk using AVIO.
8.2.20.2 iSCSI-Based Backing Stores with AVIO Require Host AVIOstor B.11.31.1009.01
If you plan to use the iSCSI-based backing stores with AVIO, you must install the HostAVIOstor
B.11.31.1009.01 driver on the VM Host.
8.2.20.3 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 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.
8.2.20.4 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.
8.2.20.5 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.
8.2.20.6 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
