Adding Disks to a Disk Group
When a disk group is first created, it contains only a single disk. You may need to add more disks to
the disk group. This section describes how to add disks to a disk group using the vxdg command
or the GUI. If you have many disks to add to the disk group, it is easier to use the vxdg command.
Usage Notes
◆ By default, the GUI assigns default disk names by appending numbers to the disk group name
so that each disk name is unique within its disk group. After the disk is under VxVM control,
you can rename it.
◆ 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.
▼ To add disks to a disk group using the command line
Use the vxdg command as follows:
# /opt/VRTS/bin/vxdg -g disk_group adddisk [disk_name=disk_device]
Example
To add disks named PRODdg02, PRODdg03, and PRODdg04 to the disk group PRODdg:
# /opt/VRTS/bin/vxdg -g PRODdg adddisk PRODdg02=
# /opt/VRTS/bin/vxdg -g PRODdg adddisk PRODdg03=
# /opt/VRTS/bin/vxdg -g PRODdg adddisk PRODdg04=
▼ To add a disk to a disk group using the GUI

2. Click the Disk group to which you wish to add a disk.
3. Choose Actions > Add Disk to Disk Group. The Add Disk to Disk Group wizard appears.
