so to clarify, the solution for removing, adding, and spinning up a scsi
disk drive is:
echo "scsi remove-single-device a b c d" /proc/scsi/scsi
echo "scsi add-single-device a b c d " /proc/scsi/scsi
in line 2, the space after the d is important due to a bug
where:
a is Host No (usually 0)
b

I have no problem with remove. My problem is about getting my disk to
spin up again after insertion. But thanks
OOPS! I copied the first echo line, but didn't edit it.

Something that could be done (which used to be done in the scsi-idle

I think the issue here is that the kernel doesn't know you have added
a disk so you need to tell it. To do that you use the following command
echo "scsi add-single-disk a b c d"/proc/scsi/scsi
a is Host No (usually 0)
b is Channel (usually 0 or 1)
c is Device Id
d is LUN (usually 0)

Yes, I already use this as part of the procedure of replacing faulty
drives. It doesn't spin up the disk for me though.
This works with my hot plug setup to spin up and make the device
accessible to the system.
Hm, not
As brian said you have to use echo "scsi add-single-disk a b c
d"/proc/scsi/scsi to insert
the new disque. Then I used scsi-start coming in the rpm scsi-idle to spin
up the disk.
(You don't need to patch the kernel with the scsi-idle stuff to have it work)
I've never tried the solution

Hi.
I'm one of the many satisfied new RAID patch/toolchain users. I use
the aic7xxx driver for the Adaptec chipset, which are both onboard
and offboard. It works great.
I have an issue though, about spinning up a SCSI disk after replacing
a faulty one using hot swap. I know the drive can be
