If you wanted to stick with grep, you could use

-B NUM, --before-context=NUM
Print NUM lines of leading context before matching lines. Places a line containing a group separator (--) between contiguous groups of matches.

More Greppin'

This may sound simplistic but can't you just grep "Channel"? Either in the way you are doing it now or with a nested grep? Pardon, I'm a little rusty in Unix. Smilie

Assuming this is a Linux kernel, have you tried looking in the /sys filesystem?

It's all driver and device specific, so I can't give you any better answers in this case off-hand, but here's some examples from a system of mine with FC storage:
Code:
$ readlink /sys/block/sda
../devices/pci0000:00/0000:00:02.0/0000:09:00.0/0000:0a:00.0/0000:0b:00.0/host2/rport-2:0-0/target2:0:0/2:0:0:1/block/sda
$ readlink /sys/block/sda/device
../../../2:0:0:1

That is *much* easier to parse...
