Hi - I've been seeing a lot of scsi errors recently on some of the drives attached to an alpha we have. All of these appear to be sense/parity errors of the form:
scsi0 channel 0 : resetting for second half of retries. SCSI bus is being reset for host 0 channel 0. SCSI disk error : host 0 channel 0 id 2 lun 0 return code = 18000002 [valid=0] Info fld=0x0, Current sd08:23: sense key Aborted Command Additional sense indicates Scsi parity error scsidisk I/O error: dev 08:23, sector 8913048 We're running 4 drives + one tape drive off a QLogic 1020 ISP adapter (via a wide->narrow adapter). The total cable length exceeds 1.5m which I've seen elsewhere on the web as being the max length for this set up. The whole bus is terminated with an active terminator and the QLogic adapter is set to auto-terminate. We're running Debian 2.2, kernel 2.2.14 with the qlogicisp driver. Are these sort of errors indicative of cabling/termination problems or should I be looking elsewhere? If we swap around/replace the cables the drive id causing the error changes so I cant believe its a drive error. What worries me is the whole machine locks up solid after these errors and I dont know whether these errors should cause that... Any ideas?
