We are running with E1A's without any problems. 3.1.2.22 server running on
AIX 4.2.1.

Two SCSI F/W Diff card and two E1A's per card. Not what I want but we are
short on slots on the server side.

Don't have the drive code level handy although it is old. Same code that
shipped in the unit. We installed 07/99. Atape is at 4.4.0.0

                H.G.,

                still having problems on two out of the four tapes.

                IBM changed on one of the two faulty drive:

                        - head      (nothing's changed)
                        - card-pack (nothing's changed)

                I changed:

                        - 3590 microcode from D0IC_994 to D0IC_A70
(nothing's changed)
                        - Atape driver downgraded 5.0.2 -> 4.6.2
(nothing's changed)

                IBM guys are scratching their heads, they run short on ideas
... I'm busy
                copying the R/O cartridges and trying to restore what it's
set as
                damaged. I wish I could go back to the old and secure
3590-1BA drives.

                I have two drive on each board (Wide/Fast-20 SCSI I/O
Controller). Can
                this be a problem given the current throughput of the new
drives?

                How many 3590-1EA do you have on a single SCSI channel and
which SCSI
                board do you have on the AIX box?
