RE: IBM 5394 Controllers corrupting diskettes

At his point, what we have surmised is:

Devices on the port 1 string go into Recovery Pending status upon
booting the controller. If we can quickly vary those devices off, then
the diskette is not corrupted. Once the other port(s) come up, then we
can vary on those devices and everything works, otherwise the diskette
get hammered and is unusable. 

DOES ANYONE KNOW IF THERE IS A REVISON OF THE 5394 SOFTWARE LATER THAN
VERSION 2.3 ? COULD A LATER REVISION OF THE HARDWARE (BASED ON SERIAL
NUMBER OF THE UNIT) REQUIRE A LATER VERSION OF THE SOFTWARE? I'm
grabbing at straws I'm sure, but I've not seen this scenario in any
other location, and we've been running these units flawlessly for almost
7 years now. The particular units we are working with at this location
have a much higher serial number than the original 35 units purchased 7
years ago, but we're using the same 2.3 version of the siftware......

Any big accu-loader at the other side of the wall or nearby, this took
me in
the past.

Did you try to connect the 5393 to another wall-outlet on another
currentbreaker. (I call it dirty powerproblem)

These are original IBM 5394 system diskettes (got 100+ originally from
IBM) The one thing that is different at this location is that one
string(port) is twinax, and the other port is CAT5 w/baluns.
Plus....this
site has been running since December!
