Changing the SCSI address (parallel SCSI drives only)
On a parallel SCSI device, if you need to change the SCSI ID for one or both of the tape drives, do
so before connecting the Library to the host computer.
The pre-configured SCSI address for all full-height tape drives in the MSL2024 and MSL4048, and
for all drives in the MSL8048 and MSL8096 is 4. For half-height drives in the MSL2024 and MSL4048,
the bottom drive of any pair has SCSI address 4 and the top drive has SCSI address 5. If these
pre-configured addresses will not be unique on a bus, you must change the SCSI ID of one or more
tape drives.
To change the SCSI ID:
1. Plug the power cord into the power connector on the back panel and then plug the cord into the
power outlet.
2. From the front panel, push the round power button to power on the device.
3. From the front panel, set the new SCSI ID for any drives that must have a different SCSI ID. For
the MSL2024, see “
Changing the SCSI address — parallel SCSI devices (Configuration > Change
Drive) ” on page 115. For the MSL4048, MSL8048, or MSL8096, see “ Changing the drive
configuration (Configuration > Drives) ” on page 144.
4. Power off the device by depressing the power button on the front panel.
TIP:
The SCSI ID can also be changed from the RMI Configure: Drive screen once the RMI is configured.
See Changing the drive configuration , page 87.
Connecting the parallel SCSI cable (parallel SCSI devices only)
NOTE:
LTO-3 and LTO-4 tape drives are Ultra 320 SCSI LVD devices. Use only cables and terminators
specified for Ultra 320 or labeled as MultiMode. LTO-2 tape drives are Ultra 160 SCSI LVD/SE
devices; use only cables and terminators specified for Ultra 160 or Ultra 320, or labeled as MultiMode.
