ioscan refresh

ROSS HANSON — Mon, 16 Aug 2004 15:36:37 GMT

After doing a ioscan -fnC disk
I see a certain disk that is connect to the system by a fibre connection.
Now after unplugging this fibre connection, it is not connected to the system at all, I do the
same command again and the disk still shows up
Is there a way of refreshing the system so this device does not show up again?

I am running a rp7420 with HPUX 11i

You will need to rmsf specific devices from the /dev/dsk and /dev/rdsk dirs

Then run an ioscan -f and a insf -e...

then do ls -lrt on /dev/dsk to ensure no new devices were created.

Easiest and fastest way would be to execute rmsf against the controller itself than against individual device files

# ioscan -fnkC ext_bus

Findout the controller HW address

# rmsf -H

# rmsf -H 8/0/19/0

# ioscan -fnC ext_bus
# ioscan -fnC disk
# insf -e
