lun discovery

Hello All,
I have an L class (11.i) attached to an xp512.
Is there any way to discover lun change ie. create/delete without having to reboot. insf-does not appear to work.

Hi Galen,

All you have to do is:

1) ioscan -fnC disk
then
2) insf

If new devices were created the ioscan will find them & the insf will create the device files.
To delete you use the rmsf command on both the /dev/dsk & /dev/rdsk entries.

HTH,
Jeff

Thanx Jeff-
I had not noticed that although the entry still exists in ioscan... it is labeled NO HW. Much appreciated.

Yes,

ioscan -fnC disk

Then,

insf -C disk

insf -e or insf -C will work

hi

if you have NO HW means the driver is already built into the kernel, but you are not able to query the hardware.

u have to remove the device files using rmsf -H hardware path.
hardware path identified from the ioscan output.

with best wishes
