Tape Drives

CAUTION:
System Degradation: Client software determines how unlabeled,
unreadable cartridges or cartridges placed upside down in the CAP are
handled.
Importing unlabeled and unreadable cartridges into the library should be
discouraged, as problems will arise every time the library audits the
cartridges.
Importing a cartridge upside down could result in damage to the hand-
camera assembly and tape drive.
Tape Drives
Tape drives may be directly connected to the client interface, daisy-chained
with other drives, or on the same bus as the library. Performance, however,
must be considered when connecting several devices on a common bus.
The library supports replacement of a drive while other drives and/or the
library remain online. This supports the ANSI SCSI-3 level 3 "hot swap"
specification.
The procedures for troubleshooting drive faults and hot swapping of drives are
discussed in

• Whenever an audit is performed, the customer must request a host update
of the audit results. This must be done to maintain identical audit
information between the library and host.
• Cartridge VOLSERs are read by the camera only during an audit or a CAP
entry. Once the audit or CAP entry is completed, cartridge movement is
done strictly by reference to MPC/MPCL memory.
