IBM TS3100 Tape Library and TS3200 Tape Library: Setup, Operator, and Service Guide Machine Type 3573
Solution
INSTALLATION/CONFIGURATION
1. Ensure that all devices on the same bus/network have unique ID numbers.
2. Ensure that you cycle power on the library after the ID is changed.
3. Reboot the host server.
1. Check the network bandwidth from the host computer. If you are backing up
data over a network, consider comparing to a local-only backup.
2. Ensure that the library and tape drive are on their own SCSI bus and not
daisy-chained to another tape drive or to the hard disk that is backed up.
3. Ensure that the library is connected to an LVDS SCSI bus and there are no
single-ended (SE) devices on the same bus, because this connection causes the
entire bus to negotiate down to SE speed.
4. Use an Ultra160 SCSI bus and height-quality cabling with the library.

This diagnostic test is available with library firmware level greater than 6.xx. Refer
to "Verifying/updating firmware" on page 60 to determine the level of firmware
on your library. If necessary, visit http://www.ibm.com to download the latest
levels of firmware for your library.
If Auto Clean is enabled and a cleaning cartridge is not present, or if a cleaning
cartridge is present but not in the reserved slot, Auto Clean status shows Chk
Media/Rsvd Slot? and Status shows a green check mark and the words Media
Attention.
