Veritas Storage Foundation for Oracle 5.0 Administrator's Guide, HP-UX 11i v3, Second Edition, December 2008

■ Veritas Storage Foundation for Oracle only supports single disk
groups.
■ Veritas Storage Foundation for Oracle RAC supports shared disk
groups. If you are in an Oracle RAC environment:
■ Create disk groups on the shared disks from the master node.
To determine if a node is a master or slave, run the following
command:
vxdctl -c mode
■ RAID-5 volumes are not supported for sharing in a cluster.
■ New disks must be placed under VxVM control and then added to
a dynamic disk group before they can be used for volumes.
■ When you place a disk under VxVM control, the disk is initialized.
Initialization destroys any existing data on the disk.
■ For information on the vxdg command, see the vxdg(1M) manual
page.
Usage notes
To create a new disk group
◆
Use the vxdg command as follows:
# /opt/VRTS/bin/vxdg init disk_group [disk_name=disk_device]
The following is an example of creating a disk group using the vxdg command:
To create a disk group named PRODdg on a raw disk partition c1t2d0, where the
disk name PRODdg01 references the disk within the disk group:
# /opt/VRTS/bin/vxdg init PRODdg PRODdg01=c1t2d0
To create a new shared disk group in an Oracle RAC environment
◆
Use the vxdg command as follows:
# /opt/VRTS/bin/vxdg -s init disk_group [disk_name=disk_device]
Where the -s option allows the disk group to be shared.
Warning: Veritas Storage Foundation for Oracle RAC supports shared disk
groups. Veritas Storage Foundation for Oracle Standard and Enterprise
editions support single disk groups.
To create a disk group named PRODdg on a raw disk partition c1t2d0, where the
disk name PRODdg01 references the disk within the disk group:
