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.
To rename a disk
# 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:
# vxdisk list DEVICE TYPE DISK GROUP STATUS hdisk3 auto:aixdisk mydg01 mydg online hdisk4 auto:aixdisk mydg03 mydg online hdisk5 auto:aixdisk - - 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:
# vxdisk list DEVICE TYPE DISK GROUP STATUS hdisk3 auto:aixdisk mydg01 mydg online hdisk4 auto:aixdisk mydg02 mydg online hdisk5 auto:aixdisk - - online
