Creating a disk group
You must associate a disk group with at least one disk. You can create a new disk
group when you select Add or initialize one or more disks from the main
menu of the vxdiskadm command to add disks to VxVM control. The disks to be
added to a disk group must not belong to an existing disk group.
You can create a shared disk group.
See “Creating a shared disk group” on page 455.
You can also use the vxdiskadd command to create a new disk group:
# vxdiskadd c1t0d0
where c1t0d0 is the device name of a disk that is not currently assigned to a disk
group. The command dialog is similar to that described for the vxdiskadm
command.
See “Adding a disk to VxVM” on page 109.
You can also create disk groups using the following vxdg init command:
# vxdg init diskgroup [cds=on|off] diskname=devicename
For example, to create a disk group named mktdg on device c1t0d0, enter the
following:
# vxdg init mktdg mktdg01=c1t0d0
