Altering a tape library

The Tape Library Alter panels are displayed when a storage administrator selects option 4, ALTER, on the Tape Library Application Selection panel or enters the alter line operator on the Tape Library List panel (see Figure 1 through Figure 7).

You can use the Tape Library Alter option to alter the attributes of an existing tape library. Altering a library results in updating the library definition within the specified SCDS and the attributes stored in the TCDB.

You can alter the tape library, LIB1, to change its definition in the tape configuration database by using the Tape Library Alter panel. To alter the tape library, start from the Tape Library Application Selection panel, shown in Figure 3:

Specify the name of the SCDS containing the tape library you want to change (SCDS.TEMP.PRIMARY).
Specify the tape library name (LIB1).
Select option 4, ALTER.

ISMF displays the Tape Library Alter panels shown in Figure 1, Figure 2, Figure 3, and Figure 4.

WARNING:
  When you connect a tape library to a system group rather than a system,
  you lose the ability to vary that library online or offline to the
  individual systems in the system group.  It is strongly recommended that
  the tape library be connected to individual systems only.
