CVM and VxVM Planning

You can create storage groups using the HP-UX Logical Volume Manager (LVM,

described in the previous section), or using Veritas VxVM and CVM software.

NOTE: Check the Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in Compatibility

and Feature Matrix and the latest Release Notes for your version of Serviceguard for

up-to-date information on CVM support: http://www.docs.hp.com ->High

Availability -> Serviceguard.

When designing a storage configuration using CVM or VxVM disk groups, consider

the following:

• You must create a rootdg disk group on each cluster node that will be using

VxVM storage. This is not the same as the HP-UX root disk, if an LVM volume group

is used. The VxVM root disk group can only be imported on the node where it is

created. This disk group is created only once on each cluster node.

NOTE: The VxVM rootdg is only required for VxVM 3.5 and earlier; it is not

required for VxVM 4.1 and later.

• CVM disk groups are created after the cluster is configured, whereas VxVM disk

groups may be created before cluster configuration if desired.
