How to remove a disk from a server

[Andrea LESSI]

I've some disks from a SAN that i want to remove from my server to dedicate them to other boxes.
I removed the related special files and then I unassigned the relation disks/host from the IBM Storage Specialist (the SAN admin utility). After that an ioscan shows to me a S/W state NO_HW for the disk I want to remove, so iI rebooted the machine, but a new ioscan still shows the disks and a NO_HW state. How can I definitively remove these disks from the system.

If you physically removed device and rebooted system then this device should dissapear in ioscan output. Where was this disk installed? Disk array?
Please attach 'ioscan -fn' to your next reply

you can use rmsf -H

LIke

for i in `ioscan -funC disk | grep -v grep | grep NO_HW | awk '{ print $3 }'`
do
rmsf -H $i
done

This will remove only the device files.
You have to perform a reboot to take out the entries pointing out to the kernel.
