scsi error

[Chris Lee <Chrislee@centurycity.com.hk>]

Hi,

I am using Redhat 7.2 w/ latest patch, and somtime found the following error
at /var/log/messages.
What does it mean? How do I fix it? 

kernel: scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id
6, lun 0 Read (10) 00 00 e1 36 f7 00 00 08 00
kernel: (scsi0:0:6:0) SCSISIGI 0x44, SEQADDR 0x77, SSTAT00x0, SSTAT1 0x2
kernel: (scsi0:0:6:0) SG_CACHEPTR 0x6, SSTAT2 0x40, STCNT0x5b2
kernel: SCSI host 0 abort (pid 0) timed out - resetting
kernel: SCSI bus is being reset for host 0 channel 0.
kernel: (scsi0:0:6:0) Synchronous at 80.0 Mbyte/sec, offset 30.

My ssci hardware config show at boot up:
