They appear in bunches of five, with the "retries" counter starting at 4, counting down to 1 and ending with "FAILURE". sd8(ncr2:2:0): error code 83 sd8(ncr2:2:0): error code 84 sd8(ncr2:2:0): MEDIUM ERROR info:1af3b csi:73,0,31,0 asc:68,0 sd8(ncr2:2:0): MEDIUM ERROR info:1af3b asc:11,0 Unrecovered read error field replaceable unit: 2 sd8(ncr2:2:0): MEDIUM ERROR info:1af3b asc:14,1 Record not found field replaceable unit: 2 Output of 'scsi -f /dev/sd8 -P 0 -m 1': AWRE (Auto Write Reallocation Enbld): 0 ARRE (Auto Read Reallocation Enbld): 0 TB (Transfer Block): 0 RC (Read Continuous): 0 EER (Enable Early Recovery): 0 PER (Post Error): 0 DTE (Disable Transfer on Error): 0 DCR (Disable Correction): 0 Read Retry Count: 32 Correction Span: 22 Head Offset Count: 0 Data Strobe Offset Count: 0 Write Retry Count: 32 Recovery Time Limit: 65535 I turned on AWRE and ARRE, but the problem persisted. It seems to have gone away after a newfs (I tested it by dd'ing /dev/zero to a file on that partition, filling it up, then reading the file back in). The disk is a Seagate Medallist 1GB SCSI-2 drive, the last drive on the third NCR53c810 controller. Is there anything I should be worried about now? ncr2 rev 2 int a irq 11 on pci0:12 ncr2 waiting for scsi devices to settle (ncr2:0:0): "Quantum XP32150 81HB" type 0 fixed SCSI 2 sd6(ncr2:0:0): Direct-Access sd6(ncr2:0:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8. 2050MB (4199760 512 byte sectors) sd6(ncr2:0:0): with 3907 cyls, 10 heads, and an average 107 sectors/track (ncr2:1:0): "Quantum XP32150 81HB" type 0 fixed SCSI 2 sd7(ncr2:1:0): Direct-Access sd7(ncr2:1:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8. 2050MB (4199760 512 byte sectors) sd7(ncr2:1:0): with 3907 cyls, 10 heads, and an average 107 sectors/track (ncr2:2:0): "SEAGATE ST51080N 0913" type 0 fixed SCSI 2 sd8(ncr2:2:0): Direct-Access sd8(ncr2:2:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8. 1030MB (2109840 512 byte sectors) sd8(ncr2:2:0): with 4826 cyls, 4 heads, and an average 109 sectors/track -- Brian Tao (BT300, taob@io.org) Systems Administrator, Internex Online Inc.
