Here is an example of SCSI AHC 2842 system crash after disk errors. I am running 2.2-STABLE as of 04:00 CST May 5. I added a Quantum 2gb Capello disk drive as target 2 several days ago. After putting about 400 meg of data on the drive, I ran a dump to a DAT tape. I got 11 read errors and then the system crashed. Both AWRE and ARRE are enabled on the drive. I then tried a tar to /dev/null to determine the files with errors. I had several system crashes after read errors. Shown below, is the error log from 1 test run. There were 2 bad files. The first showed unrecovered errors and the second only showed the abort messages. After I removed all of the files with bad sectors, I reran the dump to tape and had no problems. Following the error messages are the verbose boot messages and then the kernel configuration file. Thanks, Bob Dunaway bob@rdsw.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * May 29 13:28:25 rds1 /kernel: sd2(ahc0:2:0): MEDIUM ERROR info:2c297d asc:11,0 Unrecovered read error May 29 13:28:26 rds1 /kernel: , retries:4 May 29 13:28:28 rds1 /kernel: sd2(ahc0:2:0): MEDIUM ERROR info:2c297d asc:11,0 Unrecovered read error May 29 13:28:28 rds1 /kernel: , retries:3 May 29 13:28:31 rds1 /kernel: sd2(ahc0:2:0): MEDIUM ERROR info:2c297d asc:11,0 Unrecovered read error May 29 13:28:31 rds1 /kernel: , retries:2 May 29 13:28:33 rds1 /kernel: sd2(ahc0:2:0): MEDIUM ERROR info:2c297d asc:11,0 Unrecovered read error May 29 13:28:33 rds1 /kernel: , retries:1 May 29 13:28:36 rds1 /kernel: sd2(ahc0:2:0): MEDIUM ERROR info:2c297d asc:11,0 Unrecovered read error May 29 13:28:36 rds1 /kernel: , FAILURE May 29 13:36:31 rds1 /kernel: sd2(ahc0:2:0): SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 May 29 13:36:31 rds1 /kernel: SEQADDR = 0x4 SCSISEQ = 0x12 SSTAT0 = 0x0 SSTAT1 = 0xa May 29 13:36:31 rds1 /kernel: sd2(ahc0:2:0): Queueing an Abort SCB May 29 13:36:31 rds1 /kernel: sd2(ahc0:2:0): Abort Message Sent May 29 13:36:31 rds1 /kernel: sd2(ahc0:2:0): SCB 0 - Abort Completed.
