HP Integrity Virtual Machines Version 4.2 Release Notes

used for the volume group. As a workaround, define LVM volume groups to be used
as backing storage for VMs using legacy device files.
NOTE: This issue does not occur with disks used for VxVM volume groups. VxVM
does not yet completely support the new agile addressing, but that may change with
future versions of VxVM.
The VMMgr product V4.0 correctly excludes all LVM or VxVM volumes from the Add
Storage dialog, regardless of whether legacy or agile specifications were used to create
the volume, and correctly displays the linkages between logical volumes of either kind
to the physical storage devices used for the volume group.
These limitations will be addressed in a future release of VMMgr.
2.3.6 VxVM Device Path Not Valid Error on HP-UX 0803 Guest
Installing or updating HP-UX 0803 might result in the following VxVM error:
NOTICE: VxVM vxdmp V-5-0-34 added disk array OTHER_DISKS, datype = OTHER_DISKS
VxVM vxdisk ERROR V-5-1-5433 Device disk1_p2: init failed:
Device path not valid
* smapi listener returned "ACTION_FAILURE" for message "CREATE_GROUP"
The configuration process has incurred an error, would you like
to push a shell for debugging purposes? (y/[n]):
This error is caused by a 32–byte VxVM length limitation on disk device ID information. Integrity
VM virtual disks report back a standard T10 device ID created with the 8–byte T10 HP identifier
followed by a null terminated string of the backing store name. For example, the resource
statement, "disk:scsi::lv:/dev/vx/rdsk/lvrackA/disk1", results in the T10 device
ID, "HP /dev/vx/rdsk/lvrackA/disk1". Therefore, to avoid this error, the length of the
backing store name must not exceed 23 characters.
2.3.6.1 Installing the HP Integrity Virtual Machines Product Over the Evaluation Software
If you installed the evaluation version of Integrity VM, you must remove the evaluation software
before you install the current version of the product. For example, to remove the evaluation
version of Integrity VM, enter the following commands:
# swremove -x autoreboot=true T2801AA vmProvider
# rm -rf /opt/hpvm
# rm -rf /opt/hpvmprovider
Do not remove the directory /var/opt/hpvm. This directory contains all the virtual machine
configurations that were created with the evaluation software.
2.3.6.2 Do Not Install Applications on the VM Host System
When you install Integrity VM, HP-UX kernel parameters are changed to accommodate the
virtual machine environment. This makes the system unsuitable for running any other
applications. Regardless of whether guests are configured and running, the VM Host system is
not configured to allow applications to share system resources. You can run system management
utilities and Serviceguard, as documented in the HP Integrity Virtual Machines Installation,
Configuration, and Administration manual.
• Using backup solutions for VM Host and guest backups
Backup solutions such as HP Data Protector or Veritas NetBackup can be used on both the
VM Host system and the guest systems. Consult the support matrix of such products for
supported versions. Install the backup (client) agents on the VM Host and the guests. HP
highly recommends that the /var and /opt directories, in addition to the standard locations,
