HI!
 
We are the MOD group in chung-hua telecomm. of Taiwan.
We have 20 Hp-servers to serve the Video-On-Demand Services
Some errors as below are reported by kernel.
 
(Linux SKC5-TVS-305 2.4.28 #4 SMP Tue Jul 19 17:18:35 EDT 2005 i686 unknown).

When I trace the source of kernel, I find the following comments:
 
/* We get CMD_INVALID if you address a non-existent tape drive instead
of a selection timeout (no response). You will see this if you yank
out a tape drive, then try to access it. This is kind of a shame
because it means that any other CMD_INVALID (e.g. driver bug) will
get interpreted as a missing target. */
 
But no tape drive is in the server.
Why were the warning messages reported in the /var/log/dmesg?
