Hi,
Can anyone help me diagnose what's going in this console output?
The machine is a dual Xeon, running 4.7-STABLE #1 (Sat Feb 15).
It has been in production use for almost a year. Last week, I
replaced a failed disk; since then, these device resets have been
happening about twice a day.
I have this controller:
ahc0: <Adaptec aic7899 Ultra160 SCSI adapter> port 0xd800-0xd8ff
mem 0xfe9fe000-0xfe9fefff irq 16 at device 4.0 on pci4
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
ahc1: <Adaptec aic7899 Ultra160 SCSI adapter> port 0xdc00-0xdcff mem
0xfe9ff000-0xfe9fffff irq 17 at device 4.1 on pci4
aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/ 253 SCBs
... and these drives:
da1 at ahc0 bus 0 target 1 lun 0
da1: <HITACHI DK32DJ-18MC AAAA> Fixed Direct Access SCSI-3 device
da1: 160.000MB/s transfers (80.000MHz, offset 100, 16bit), Tagged Queueing Enabled
da1: 17628MB (36102720 512 byte sectors: 255H 63S/T 2247C)
da0 at ahc0 bus 0 target 0 lun 0
da0: <SEAGATE ST318452LC 0004> Fixed Direct Access SCSI-3 device
da0: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged Queueing Enabled
da0: 17501MB (35843670 512 byte sectors: 255H 63S/T 2231C)
... and the console messages follow.
Thanks,
