Question :
Alpha 4100A Ver 4.0D patch#3 HSZ70 rz1df-cb
We have been getting scsi cam errors that are basically
resets . They happen on different 'devices' on different
RAID 5 sets . These raid sets have been partitioned off
and the logical disks thrown into LSM to use as raw
(sybase) database devices. The engineer is returning
to replace the controller , cable etc .
My question is , could these resets cause a database
corruption . I am getting NO errors in LSM or anywhere
else . Our database has corrupted twice in the last week .
Sybase says yes , it's a hardware problem and this must
be it . I don't see how .
Thanks to Allan (Borg) Rollow for the following :
This particular reset happened behind the hosts's back and
was completely in the controller. The HSZ must have gotten
pretty desparate to think that a bus reset was the only way
to get the particular port to behave. Whatever happened
before this to result in a bus reset, could certainly have
corrupted data. It could still be an insane device on that
particular bus, or a bad backplane, but a bad controller is
the easiest thing to swap.
It does indeed seem to be caused by the controller .
A swap fixed the resets . The database still corrupts
but that's another problem .
Thanking you ,
