Datasheet

Note:
z * 4mm tape drives will flash the Amber LED
z ** 4mm tape drives will put the Amber LED on solid
z *** 8mm 5GB, & 7GB put the Amber LED on solid after 30 hours of tape motion without the drive being cleaned.
8mm 20GB put the Amber LED on solid after 70 hours of tape motion with AME media and 20 hours with MP
media.
z 8mm 2.3GB, 5GB, 7GB, & 20GB tape drives will log a TAPE_ERR3 when: Rewrite % is equal to or greater than 2%
with at least 100mb of data written,
or
Reread % is equal to or greater than 1% with at least 20mb of data read.
z The 20GB drive MUST BE CLEANED after using 15m, 54m, 112m, or 160m length media before any subsequent
write operation will be allowed.
z TAPE_ERR3 and TAPE_ERR6 are "soft errors" that are posted to the AIX error log. In other words, neither error
terminated the tape operation. They are informational errors that may cause AIX to send an informational message to
the user.
z TAPE_ERR4 errors are often found to be caused by noise on the SCSI bus. Noise on the SCSI bus can be caused by
one or more of the following:
{ Loose SCSI Cables (reseat and tighten all SCSI connections).
{ Bent pins in the SCSI connection (check all SCSI connections for bent pins).
{ Device is not supported on the SCSI adapter/system(insure device is supported by the SCSI adapter/system).
{ Improper, missing or multiple SCSI bus termination(check SCSI bus termination).
{ SCSI cables(insure the proper IBM SCSI cables are used).
{ SCSI cables exceed the supported length for the bus(check the IBM information on SCSI bus length).
{ Other SCSI devices on the bus(it may be necessary to remove the other SCSI devices one at a time to determine
device causing the problem).
Tape Drive Problem Determination
Details the steps that should be taken to resolve problems.
Tape drives are very expensive and often are not the reason a tape cannot be read or written. Often the problem is caused by
one or more of the following:
z Not cleaning the tape drive, using cleaning cartridges that are used up, use of cleaning cartridges that are not
supported, not following the recommended cleaning frequency, or cleaning instructions.
