We've been having a lot of problems with our SCSI setup. System is:
- Pentium 100 - ASUS P55TP4XE motherboard
- BusLogic 956C PCI wide scsi card with firmware version 4.26B
- 3 Conner CFP1060S drives and 2 Conner CFP1080S drives (all narrow-scsi
drives)
Symptoms include:
- BusLogic card failing to initialize itself when doing a warm reboot (ie,
the bios does the memory check, then the BusLogic cards prints its banner
and then just sits there. It doesn't even get to the "Press Ctrl-B to
Enter AutoSCSI" stage
- disk corruption
- lots of SCSI bus resets
With the BusLogic card in there, the system won't stay up longer than 24
hours (and it can be as short as 5 minutes). At the moment I'm using a
NCR53c810 card to keep the server up and running.
I've tried the existing BusLogic driver in the 1.2.13 kernel and Leonard's
new BETA driver. I've tried disabling FAST scsi operation. Have changed
the SCSI cable and rechecked termination settings a million times. Have
disabled Tagged Queueing. All with little effect. I've also placed a
couple of fans inside the case to keep the drives nice and cool (after we
cooked two of them).
The only items left are either that the card itself is faulty or there's
an incompatibility between the card and the motherboard.. (Or is there
something else?). The fact that the card can't reinitialize itself when
doing a warm reboot makes me suspect that the card is faulty. I've
ordered a replacement but it won't be here for a while :( Anything I can
do in the meantime?
Also, the following errors appear in my log files after I reboot:
SCSI disk error : host 0 id 4 lun 0 return code = 2
scsidisk I/O error: dev 0841, sector 1000324
These would indicate a bad sector on the drive, right?
Thanks in advance for any help.
