perform the mount in the most timely manner. If the library's primary accessor
fails, the second accessor assumes control and eliminates system outage or the
need for operator intervention.
Although the library uses defaults to specify the zones (areas) in which the
accessors operate, you can specify particular zones by using the Tape Library
Specialist Web interface. This process is called setting the preferred zone. For
details, see the section about setting the preferred zone in the
IBM System Storage
TS3500 Tape Library with ALMS Operator Guide .
Service bay A (the HA1 frame) contains only gripper test slots (
1
in Figure 5) for
diagnostic cartridges. Service bay B contains gripper test slots
2
for diagnostic
cartridges, and also contains unusable storage slots
3
. The storage slots in service
bay B are not used if the frame is configured as a service bay. Figure 5 shows the
location of slots in an example of a service bay.
If you already have an installed TS3500 Tape Library and you want to add a
second accessor, your IBM service representative can add the accessor and its
service bays. Converting from a single accessor to a dual accessor library requires
that the service representative take down the entire library.
If your library already contains the service bays and you decide to add one or
more expansion frames, your IBM service representative can convert service bay B
to an expansion frame, add the new frame or frames to the right, and convert the
last frame on the right to service bay B. This process requires no scheduled
downtime. (
Downtime is designed to be less than one hour.) To convert the existing
service bay to an expansion frame, the service representative removes the test slots
and replaces them with storage slots. Similarly, to convert an expansion frame to a
service bay, the service representative removes specific storage slots and replaces
them with the test slots. For more information, contact your IBM service
representative.
