The library or autoloader is now ready to resume operation. If you replaced a
SCSI tape drive, the new tape drive automatically assumes the SCSI ID of the
old drive. If you installed an additional SCSI tape drive in the 221L, set the
SCSI ID for the drive as described in the
221L and 221L-FC Product Manual
.
If you installed or replaced a Fibre Channel tape drive in the 221L-FC, refer to
the
221L and 221L-FC Product Manual
for information about setting the tape
drive’s Loop ID.
You may want to perform some hardware exercises to ensure that the library
and the newly installed tape drive are communicating correctly. See the
221L
and 221L-FC Product Manual
for instructions.

§
Are the devices on each SCSI bus
attached to the autoloader or library
all LVD?
§
Are the SCSI buses terminated?
§
Are the SCSI cables firmly connected
to the autoloader or library, tape
drive(s) and host computer?
§
Are the SCSI IDs unique for the
devices on each SCSI bus?
§
Have you connected more than two
tape drives to the same SCSI bus? For
best performance, avoid connecting
more than two LTO tape drives to the
same bus.
§
Is the library or autoloader operating
in the correct control mode? (For
most applications, the control mode
should be set to SCSI.)
§
Are the GBICs and cables used to
connect the tape drives to the Fibre
Channel loop compatible?
§
Are the Fibre Channel cables firmly
connected to the library, tape drives,
and the Fibre Channel hub or switch?
§
Is the library operating in the correct
control mode? (For most applications,
the control mode should be set to
SCSI.)
