We have several customers who failed to install AIX 3.2.5 on RS/6000
models 32H and 340, using 4mm installation media and a 4mm tape
drive model 7206-001 . The machines could not boot from the 4mm
tape drive. They also tried to boot from diskettes and then install
the 4mm tape, but they had problems with that approach, too
(usually the machnies got "stuck" during or after the installation).
When they tried to install the machines from an 8mm tape drive model
7208-001 there were no problems. What could be the cause of these
problems ? Is the 4mm tape 7206-001 fully supported under AIX 3.2.5
and RS/6000 models 32H and 340 ?
ANSWER
The 7206 model 001 4mm tape drive is fully supported on the 32H
and the 340 under AIX 3.2.5. However, after much research, I
have found a possible explanation.
A problem has been reported previously regarding the 7206-001
when attached to a SCSI I/O controller. The SCSI I/O controller
which the 4mm tape drive is connected to must have a microcode
level of 50 or higher when trying to boot off of the tape drive.
Apparently, the SCSI adapter is unable to communicate with the
7206 if this update has not been made (due to a microcode
incompatibility between the tape drive and the SCSI controller).
Please check to see what type of SCSI I/O controller is being
used. To do this, and to check the microcode level of the
controller, type in "lscfg -vl scsiX" where scsiX is the SCSI
controller the tape drive is connected to. The field of
interest is the "ROS Level" field.
