IBM TotalStorage 3494 Tape Library, Operator'S Manual

Page: 411 / 605

Using Manual Mode
You can use Manual mode during the following conditions:
v
A problem in the 3494 Tape Library prevents automated operations.
v A service representative is performing scheduled maintenance activities.
The Library Manager allows you to select Manual mode from the Mode menu of
the Operator menu bar (see “Manual Mode” in “Using the Mode Menu” on page
140).
When in Manual mode, you follow the instructions on the Library Manager
display and confirm as necessary when you complete the instructions. The 3494
Tape Library continues to process automatically mount and demount requests that
are issued to the virtual tape drives in a VTS. These requests are not included in
the actions that display for operator processing. If a logical volume needs to be
recalled from a physical volume in order to satisfy a mount to a virtual drive, the
actions that are required under Manual mode include the resulting mount for that
physical volume.
Typical actions include physical cartridge mounts, demounts, and ejects (removing
cartridges from the 3494 Tape Library). A sample window with pending actions is
shown in Figure 242 on page 387.
The Library Manager recognizes when a requested physical cartridge is mounted
successfully in the requested drive and removes the mount request from the list
automatically. Instructions to eject a cartridge are removed from the list manually
when you use the keyboard to confirm (respond) that the action is completed or
has an error.
A limited number of processed instructions can be viewed on the Library Manager
display to correct any mistakes (see Figure 244 on page 393).
See “Cartridge Storage Cells” on page 37 for a description of the From and To
locations used to find a cartridge for a mount.
Note:
The display windows shown are examples. They may not be exactly the
same as the windows on your Library Manager display.
Attention: In the event the Library Manager cannot park the accessor, it is
possible usually to operate the 3494 Tape Library in Manual mode. The operator
should move the accessor manually only to gain access to a cartridge or to a drive.
If necessary, perform “Cartridge Removal from the Gripper” on page 415. Call
your service representative.

To start Manual mode, perform the following steps:
Note: Enable Inventory Update if it is disabled or verify Inventory Update is
enabled before selecting Manual mode.
1.
Select Mode (Figure 238 on page 386) from the Operator menu bar at the
Library Manager (see “Using the Mode Menu” on page 140).
