VERITAS Volume Manager 3.2 for HP-UX Release Notes

What’s in This Version

Chapter 116

used to control the root/boot disk. In HP-UX 11i, aVxVM whole disk file system only works if

the disk is 2GB or less, therefore if a volume manager is used for the root disk, it must be

LVM.

Both LVM and VxVM utilities are aware of the other volume manager, and will not overwrite

disks that are being managed by the other volume manager. As mentioned above, the

administrative utilities (SAM and vmsa) recognize and identify all disks on the system.

Although this release is targeted at new customer installations, a conversion utility,

vxvmconvert, is provided for converting LVM volume groups to VxVM volume groups. Refer

to the VERITAS Volume Manager 3.2 Migration Guide for details on using vxvmconvert.

Limitations of this Release

VERITAS Volume Manager 3.2 for HP-UX has the following limitations, which will be

removed in subsequent releases:

• You cannot use VERITAS Volume Manager 3.2 for HP-UX to control the root/boot disk. If a

volume manager is used for this purpose, LVM must be the chosen volume manager.

• Only version A.11.13 of MC/ServiceGuard and ServiceGuard OPS Edition for HP-UX 11i

will work with VERITAS Cluster Volume Manager 3.2 for HP-UX.

• Only version A.11.13 of MC/ServiceGuard for HP-UX 11i will work with VERITAS Volume

Manager 3.2 for HP-UX.

• The VERITAS Volume Manager for HP-UX does not support the HP Process Resource

Manager (PRM). If you use PRM, you will not be able to gather statistics on disks

managed by VxVM. A patch is being prepared to address this problem, but the patch

number was not known when this document was written. See “Patches and Fixes in This

Version” for instructions on finding the latest patches.

• A disk monitor integrated with the EMS framework is not yet available for disks being

managed by VERITAS Volume Manager 3.2 for HP-UX.

• You must use LVM to manage your cluster lock disk; you cannot use VERITAS Volume

Manager for HP-UX or VERITAS Cluster Volume Manager 3.2 for HP-UX to manage a

cluster lock disk with this release.

• The maximum number of nodes in a ServiceGuard cluster is 4 in this release of VERITAS

Cluster Volume Manager 3.2 for HP-UX.
