Hello, everyone! This question is probably off-topic, but I can think of no better place to ask ;-) Last Friday the power supply of one of the Alphas I administer (a 4 year old DEC 3000 600) died, so I took out its two disk drives and put them on an identical machine, but the only thing I got was a lot of beeps from the drives. So I took them out again and put one of them on a FreeBSD 3.0-CURRENT system (buildworld made on January 4th) with a Symbios 53c810 SCSI card to see what I could find out. Here are the relevant dmesg lines: [snip] FreeBSD 3.0-CURRENT #2: Fri Jan 15 21:36:04 CET 1999 [snip] ncr0: <ncr 53c810a fast10 scsi> rev 0x12 int a irq 9 on pci0.11.0 [snip] da0 at ncr0 bus 0 target 2 lun 0 da0: <DEC RZ26L (C) DEC 440C> Fixed Direct Access SCSI-2 device da0: 10.0MB/s transfers (10.0MHz, offset 8), Tagged Queueing Enabled da0: 1001MB (2050860 512 byte sectors: 64H 32S/T 1001C) But whenever I issue a command that tries to access the disk, I get an I/O error, a concert of beeps from the drive when it tries to spin up, and this kind of messages on the console (this one is from issuing a disklabel -r /dev/rda0c) (da0:ncr0:0:2:0): READ(06). CDB: 8 0 0 0 1 0 (da0:ncr0:0:2:0): HARDWARE FAILURE info:300d00f8 asc:40,83 (da0:ncr0:0:2:0): Diagnostic failure: ASCQ = Component ID field replaceable unit: 2 da0: error reading primary partition table reading fsbn 0 I haven't tried the same with the other drive, a DEC RZ28, but symptoms were the same... My questions are: - Has anybody experienced this kind of disk failure, and if so, what has failed? - Is there anything I can try to bring them back to life or, as I suspect, their only utility is to hold the papers on my desk? :-( Thanks in advance for any piece of advice, Santi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the messagehelp
