TSM Server Redefine Tape Library & Drives

Redefining Tape Library in AIX

1. Run the following commands and save the output.
   1. tsm> QUERY STATUS (get SERVERNAME value for "<tsm_server_name>")
   2. tsm> QUERY DEVCLASS
   3. tsm> QUERY LIBRARY FORMAT=DETAIL
   4. tsm> QUERY DRIVE FORMAT=DETAIL
   5. tsm> QUERY PATH FORMAT=DETAIL
2. Run the following commands and save the output:
   1. # lsdev -Cc tape
   2. # lsdev -Cc adsmtape
   3. # lsdev -Cc library
3. Remove the drive paths:
   1. tsm> DELETE PATH <tsm_server_name> <drive_name> SRCTYPE=SERVER DESTTYPE=DRIVE LIBRARY=<library_name>
4. Delete the drive definition:
   1. tsm> DELETE DRIVE <library_name> <drive_name>
5. Delete the tape library path:
   1. tsm> DELETE PATH <tsm_server_name> <library_name> SRCTYPE=SERVER DESTTYPE=LIBR
6. Delete the library definition:
   1. tsm> DELETE LIBRARY <library_name>
7. Delete the OS devices:
   1. Delete the individual drives:
      1. # rmdev -Rdl <rmt#> (from step 2.1)
   2. Delete the library:
      1. # rmdev -Rdl <smc#> (from step 2.3)
8. Redefine the OS devices:
   1. # cfgmgr -v
9. Redefine the library definition:
   1. tsm> DEFINE LIBRARY <library_name> LIBTYPE=<library_type> SERIAL=AUTODETECT
10. Redefine the library path:
    1. tsm> DEFINE PATH <tsm_server_name> <library_name> SRCTYPE=SERVER DESTTYPE=LIBRARY DEVICE=</dev/smc#>
11. Redefine the drive definitions:
    1. tsm> DEFINE DRIVE <library_name> <drive_name> SERIAL=AUTODETECT ELEMENT=AUTODETECT
12. Redefine the drive paths:
    1. tsm> DEFINE PATH <tsm_server_name> <drive_name> SRCTYPE=SERVER DESTTYPE=DRIVE LIBRARY=<library_name> DEVICE=</dev/rmt#>
13. Verify the library and paths are online:
    1. tsm> QUERY LIBRARY <library_name> FORMAT=DETAIL
    2. tsm> QUERY DRIVE <library_name> * FORMAT=DETAIL
    3. tsm> QUERY PATH * * FORMAT=DETAIL
14. Recreate the volume inventory:
    1. CHECKIN LIBVOL <library_name> SEARCH=Y STATUS=SCR CHECKL=BARC
    2. CHECKIN LIBVOL <library_name> SEARCH=Y STATUS=PRI CHECKL=BARC
