If you do not specify a VM disk name, VxVM gives the disk a default name when you add the disk to VxVM control. The VM disk name is used by VxVM to identify the location of the disk or the disk type.
# vxedit [-g diskgroup] rename old_diskname new_diskname
By default, VxVM names subdisk objects after the VM disk on which they are located. Renaming a VM disk does not automatically rename the subdisks on that disk.
For example, you might want to rename disk mydg03, as shown in the following output from vxdisk list, to mydg02: #
sdb auto:sliced mydg01 mydg online
You would use the following command to rename the disk.
# vxedit -g mydg rename mydg03 mydg02
To confirm that the name change took place, use the vxdisk list command again:
sdb auto:sliced mydg01 mydg online
sdc auto:sliced mydg02 mydg online
