Renaming a disk
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
◆
Type the following command:
# 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
c0t0d0 auto:hpdisk mydg01 mydg online
c1t0d0 auto:hpdisk mydg03 mydg online
c1t1d0 auto:hpdisk - - 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
c0t0d0 auto:hpdisk mydg01 mydg online
c1t0d0 auto:hpdisk mydg02 mydg online
c1t1d0 auto:hpdisk - - online
Reserving disks
By default, the vxassist command allocates space from any disk that has free
space. You can reserve a set of disks for special purposes, such as to avoid general
use of a particularly slow or a particularly fast disk.
