Adding a Disk to a Disk Group
You can add a new disk to an already established disk group. For
example, the current disks have insufficient space for the application or
work group requirements, especially if these requirements have
changed.
To add an initialized disk to a disk group, use the following command:
# vxdiskadd devname
For example, to add device c1t1d0 to rootdg, use the following
procedure:
Step 1. Enter this command to start the vxdiskadd program:
# vxdiskadd c1t1d0
The vxdiskadd program displays the following message. Enter y to
continue the process.

be added or press Return to accept rootdg:
You can choose to add this disk to an existing disk
group, a
new disk group, or leave the disk available for use by
future
add or replacement operations. To create a new disk
group,
select a disk group name that does not yet exist. To
leave the
disk available for future use, specify a disk group name
of
“none”.
