The disk array was fully functional under windows 2000 using w2k raid prior to it being moved to FreeBSD with the mylex controller. Occasionally there are errors using the disk array, and they don't appear to be on any specific device (drive). Any idea what might cause this? > > mly0: physical device 1:15 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:13 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:10 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:9 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:9 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:10 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:14 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:13 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:9 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > mly0: physical device 1:14 sense data received > mly0: sense key 11 asc 47 ascq 00 > mly0: info 00000000 csi 00000000 > > Those messages appear sporadically. The server also appears to lock up with heavy disk usage, but only periodically (I have yet to replicate the error while I was onsite in order to see what it is printing on the screen). > > The drives in the 8 disk array are all Seagate ST318404LW 0002. I have included the dmesg for what help it provides. You're getting SCSI parity errors, reported by the drives. (SCSI ASC 47, ASCQ 0 means there is a parity error. See the SCSI specs at www.t10.org for more sense codes.) You have a bad SCSI bus configuration, probably cabling or termination.
