Deleting an XLV Object

Caution: The procedure in this section can result in the loss of data if it is not performed properly. It is recommended only for experienced IRIX system administrators. You can delete a volume or any other XLV object by using the xlv_mgr command. The procedure is:

1. If you are deleting a volume, you must unmount it first. For example:

   # umount /vol1

2. Start xlv_mgr and list each object on the system:

   # xlv_mgr

   xlv_mgr> show -long all

   VOL root_vol (complete)

   VE root_vol.data.0.0 [active]

   start=0, end=988091, (cat)grp_size=1

   /dev/dsk/dks0d2s0 (988092 blks)

   VE root_vol.data.1.0 [active]

   start=0, end=988091, (cat)grp_size=1

   /dev/dsk/dks0d2s7 (988092 blks)

   This example shows one high-level object, a volume with two plexes in a data subvolume (root_vol.data.0 and root_vol.data.1). Each plex has one volume element.

3. If the element you want to delete is not a high-level object, you must first detach it from its high-level object. For example, to delete one of the plexes in the example, it must first be detached:

   xlv_mgr> detach plex root_vol.data.1 plex_to_be_deleted

   Detached objects must be given a name, in this case plex_to_be_deleted.

4. Delete the object, in this example the plex plex_to_be_deleted:

   xlv_mgr> delete object plex_to_be_deleted

5. Confirm that the object is gone:

   xlv_mgr> show -long all

   VOL root_vol (complete)

   VE root_vol.data.0.0 [active]

   start=0, end=988091, (cat)grp_size=1

   /dev/dsk/dks0d2s0 (988092 blks)

6. Exit xlv_mgr:

   xlv_mgr> quit
