I'm using Adaptec SCSI Cable 68pin HD to 68pin HD, LVD, 3 meters
each, one cable per card. We don't use cables from StorageTek,
because we didn't get any, so i ordered them myself at one of our
local suppliers.

Because of that, i'm quite sure that the cables are ok, but i will
re-check the cabeling tomorrow.

The only cables that are not from the above Adaptec set, are the two
used for the Library control and for the staging device (external
SCSI disk array), but they aren't producing any errors...


With kind regards,
