Using the Manage Unassigned Volumes window, shown in Figure 150 on page
250, you can assign the volumes in the Unassigned category to the Import
category, assign volumes to the appropriate Insert category and partition based on
the volser ranges, or eject a volume.
If any volser character is unreadable or invalid (not A–Z, 0–9, or blank), the volser
is not added to the inventory. The cartridge is ejected to an I/O station. A volume
notification message is sent to all attached hosts indicating that a volume remains
in the I/O station with an unreadable or invalid label. If this happens, you must
determine why the volser is unreadable and correct the label before trying to
reinsert the cartridge.
If the vision system cannot determine the cartridge media type, the volser does not
fit into an established volser range, and a default media type is not defined, the
cartridge is ejected to an I/O station.
When a volser that is already in the inventory is inserted into the convenience I/O
station (a possible duplicate volser), an audit is performed. If the volser is a
duplicate, the cartridge is ejected to the convenience I/O station. If the volser is
not a duplicate, the cartridge from the convenience I/O station is left in the new
home cell.
If the misplaced or inaccessible volume indicators are set in the database, they are
reset and a notification is sent to all attached hosts that indicates that the volume
was found or made accessible again. Also, if the volume was used during Manual
mode indicator was set, it is reset.
A notification that describes the results of the audit is sent to all attached hosts.
Note: A service volume found in the convenience I/O station causes a validity
check because its volser contains an invalid character: an embedded blank.
A service volume must, instead, be placed in the cell reserved for it in the
3494 Lxx Frame. It also may be inserted using a special service volume
insert process available in Service mode.
Logical Volser Validity Checking
When logical volumes are inserted into the 3494 Tape Library (see “Manage
Logical Volumes” on page 279), the Library Manager checks the volser range
values for validity.
The Insert Logical Volumes function is not performed under any of the following
conditions:
v
The volser range characters are invalid (not A–Z or 0–9).
v There are fewer than six characters in the volser.
v
The two volsers entered are not in the same format.
The corresponding characters in each volser must both be either alphabetic or
numeric. For example, AAA998 and AAB114 are in the same format, but AA9998
and AAB114 are not.
Logical volume volsers must be unique within a physical library. If a volser
already exists in the database for any logical library (non-VTS or VTS), the logical
volume is not inserted. The Library Manager then attempts to insert the next
logical volume.
