Resolving Problems Reported by the Server
The procedure for fixing interface bus errors varies, depending on
whether the error is consistent or intermittent, and on your
configuration. The sections that follow describe how to fix an error.
Fixing SAS Bus Errors
1 Check if the tape drive power is on.
2 Verify the SAS cable is connected properly to the server and to the
tape drive.
3 Replace SAS cable if it shows any signs of damage.
Resolving Media-Related Problems
To resolve problems that are related to media, the drive's firmware
includes:
• Test Cartridge & Media diagnostic that verifies whether a suspect
cartridge and its magnetic tape are acceptable for use.
• Statistical Analysis and Reporting System (SARS) to assist in isolating
failures between media and hardware. To determine the cause of
failure, SARS uses the cartridge performance history that is saved in
the cartridge memory (CM) and the drive performance history that
is kept in the drive's VPD (Vital Product Data) area in NVRAM. Any
failures that SARS detects are reported as TapeAlert flags on the
server (see IBM LTO Ultrium Tape Drive SCSI Reference).
Caution: If you insert the Quantum LTO Ultrium Data Cartridge into
another manufacturer's drive, the SARS data in the
cartridge memory may become lost or invalid.
If you encounter a media-related problem, refer to Function Code E: Test
Cartridge & Media on page 57.
