Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

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.
Note: Veritas Storage Foundation forOracle RAC supports shared disk groups.
Veritas Storage Foundation for Oracle Standard and Enterprise edition support
both single and multiple 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:
# /opt/VRTS/bin/vxdg -s init PRODdg PRODdg01=c1t2d0
Adding disks to a disk group
When a disk group is first created, it can contain only a single disk. You may need
to add more disks to the disk group. Before adding disks, review the following:
■ When you place a disk under VxVM control, the disk is
initialized. Initialization destroys any existing data on
the disk.
■ Disks must be under VxVM control and in a disk group
before they can be used to create volumes.
■ Disks must be online before they can be added to a disk
group.
■ Disks that already belong to a disk group cannot be added
to another disk group.
