You cannot delete the file space data unless your TSM administrator has authorized your node to do so. Authorization permits you to delete backup data, archive data, or both.

Delete processing fails with the error: ANS1126E: The file space cannot be deleted because this node does not have permission to delete archived or backed up data.

Lack of permissions from TSM to allow deletion.

WORKAROUND:
Use the DSMC QUERY SESSION command to verify your authorization. Ask your TSM administrator to provide the necessary authorization or to delete the file space for you.

NOTE: This is not a LiteSpeed error.
