Can't fill in all of the details on the levels that we ended up at (been
awhile ago) but we ran 3570's in a 3575 L32 for roughly a year. Saw pretty
much everything described in the attached. Thankfully we have moved to
3590E's in a 3494..... Almost forget that they are in the data center they
are running some smoothly!

For the 3575/3570 we ended up going with the latest device driver on the AIX
side, latest microcode on the drives and also upgraded the E-PROM on the
3575. Once all that was done it actually started to run pretty good....
About a month later the new library was installed......

                Steve,
                I also have 3570's that give me fits.  I don't get the same
reaction as
                you, but I get read/write errors and all sorts of other tape
operation
                errors.  I just opened a complaint with IBM about this.  I'm
afraid I can't
                offer you a solution, just the comfort of knowing someone
else is also
                having problems with these drives.

                Brad

                Hi All,

                I'm running a 3575-L06 library with two 3570C drives and
standard length
                tapes
                under AIX 4.3.2.
                Several times in the last couple of months these drives have
reported a
                write
                error on a tape and gone into a continuous reset cycle with
all lights
                flashing.
                The only way out of this appears to be a power off and on.
Last night this
                happened first on one drive and a few hours later on the
other.
                I've updated microcode on the drives to the latest available
level, and I'm
                a
                bit downlevel on Atape at 4.1.7.0. Every tape that I've had
these errors
                reported on appears to be good when either tested or placed
back into
                service.

                Has anyone else had this problem and does anyone know of a
fix?

                Thanks
