Alpha 4100A Ver 4.0D patch#3 HSZ70 rz1df-cb
Hi All ,
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 .
