GuestAVIOStor: Instance numbers for AVIO/VIO disks fixed due to HBA type changes.<br />
GuestAVIOStor: Refer to /etc/opt/gvsd/files//gvsd.log for details.<br />
8.2.6 Agile Device Name Recommendations<br />
The <strong>Integrity</strong> VM commands supports mass storage agile device names. Use of agile device names<br />
(with the exception of attached devices using avio_stor, which uses the hardware path) for<br />
configuring storage devices is highly recommended as it provides VM Host multipathing benefits.<br />
8.2.7 Configuration Limits<br />
A guest can have up to 158 LUNs — 128 AVIO and 30 VIO. A guest can have a maximum of<br />
30 file backing stores, including both AVIO and VIO.<br />
8.2.8 Using USB CD/DVD Devices<br />
With VIO (scsi adapter type), USB CD/DVD devices are not supported for use as attachable media.<br />
AVIO (avio_stor adapter type) supports USB 2.0 DVD burners. Hardware supportability requirements<br />
for <strong>Integrity</strong> VM are described in the <strong>HP</strong> <strong>Integrity</strong> <strong>Virtual</strong> <strong>Machines</strong> Installation, Configuration, and<br />
Administration manual.<br />
To identify USB CD/DVD devices, use the ioscan -fun command.<br />
NOTE: Because <strong>Integrity</strong> VM may do four to six calls to open() on a DVD when accessing it,<br />
and hpvmcreate or hpvmmodify command might take more than a minute to complete when<br />
there is no media in the drive. Example commands that could appear to hang are:<br />
# hpvmcreate -P guest -a dvd:scsi::disk:/dev/rdisk/disk5<br />
# hpvmcreate -P guest -a dvd:scsi::null:/dev/rdisk/disk5<br />
# hpvmmodify -P guest -a dvd:scsi::disk:/dev/rdisk/disk5<br />
# hpvmmodify -P guest -a dvd:scsi::null:/dev/rdisk/disk5<br />
8.2.9 The sam Command might Display Incorrect Number of Disks and Paths on an<br />
<strong>HP</strong>-UX 11i v2 Guest<br />
The number of disks displayed by the sam command using “Sam Areas->Disks and File<br />
Systems->Disk Devices” might be incorrect. The number of paths displayed for a device might also<br />
be incorrect. This problem exists on disks configured under both SCSI and AVIO storage adapters.<br />
ioscan displays all the disks correctly.<br />
For example, the following are the sam output and theioscan output on the same <strong>HP</strong>-UX 11i v2<br />
guest:<br />
"Disk Devices" window in sam(1M) shows the following disks and number of paths:<br />
