Deleting storage-related objects

6.5.6 Deleting storage-related objects To remove storage-related objects, we use variations of the delete command. To delete objects in the storage hierarchy, you must first delete objects that depend on the object you wish to delete. Suppose you want to delete a library. You must first remove any references to it. The following objects must first be removed before deleting the library: Paths to drives in the library Drives in the library The path to the library If you wish to remove all objects associated with a library, you should also remove the storage pools and device classes using the library. You do not have to delete the device class or storage pools using the library to delete the library. Tape volumes are bound to a device class; if you wish to delete the device class you must first delete all the tape volumes that are bound to it. Deleting all those tape volumes may not be desirable. However, if you wish to keep using the tapes, you will need to create a new library that uses the same device class as the one being deleted. You can only delete a storage pool if there are no storage pool volumes assigned to it. If there are storage pool volumes assigned, you need to use delete volume to remove them first. With delete volume, you can specify whether to discard any data stored on the volumes. Be very careful with this command. You can also use move data to move data from one storage pool to another. Example 6-32 shows the sequence of commands required to remove a library. Example 6-32 Library deletion command sequence tsm: ATLANTIC>del path atlantic dr00 srct=server destt=drive libr=3582lib ANR1721I A path from ATLANTIC to 3582LIB DR00 has been deleted. tsm: ATLANTIC>del path atlantic dr01 srct=server destt=drive libr=3582lib ANR1721I A path from ATLANTIC to 3582LIB DR01 has been deleted. tsm: ATLANTIC>del drive 3582lib dr00 ANR8412I Drive DR00 deleted from library 3582LIB. tsm: ATLANTIC>del drive 3582lib dr01 ANR8412I Drive DR01 deleted from library 3582LIB. tsm: ATLANTIC>del path atlantic 3582lib srct=server destt=library ANR1721I A path from ATLANTIC to 3582LIB has been deleted.

6.5.6
Deleting storage-related objects
To remove storage-related objects, we use variations of the
delete
command. To
delete objects in the storage hierarchy, you must first delete objects that depend
on the object you wish to delete.
Suppose you want to delete a library. You must first remove any references to it.
The following objects
must
first be removed before deleting the library:
±
Paths to drives in the library
±
Drives in the library
±
The path to the library
If you wish to remove all objects associated with a library, you should also
remove the storage pools and device classes using the library. You do not have to
delete the device class or storage pools using the library to delete the library.
Tape volumes are bound to a device class; if you wish to delete the device class
you must first delete all the tape volumes that are bound to it. Deleting all those
tape volumes may not be desirable. However, if you wish to keep using the tapes,
you will need to create a new library that uses the same device class as the one
being deleted.
You can only delete a storage pool if there are no storage pool volumes assigned
to it. If there are storage pool volumes assigned, you need to use
delete volume
to
remove them first. With
delete volume
, you can specify whether to discard any
data stored on the volumes. Be very careful with this command. You can also use
move data
to move data from one storage pool to another.
Example 6-32 shows the sequence of commands required to remove a library.
