how to make iscsi disk offline

[Prashant Bhushan]

Hi,

I am using HP-UX 11.11 and installed iscsi
B.11.11.03e.

I have discovered and mounted iscsi disk using iscsiutil and ioscan.
I have deleted the discovery address using
#iscsiutil -d -I IP_ADDRESS.

In iscsiutil -pS, it is still showing session state as online.

Session # 3
------------
Session Instance No. : 3
ISID : 0x800000000003
Session State : Online

How to make that session state "Offline".?

Have you tried rmsf ?
You can run it with the hardware address from ioscan:

# ioscan -fC disk
# rmsf -H

You might also try the -r option for iscsiutil. Or if you don't have other iscsi connections in use, do a restart of the iscsi driver.

its working now. Now the session state shows offline. But for ioscan command it is still showing iscsi disk entries.

ioscan -fnC disk

Why those entries are still there?
There are no operational targets now. I also deleted iscsi discovery address.

If i use rmsf to delete those entries. I could not discover targets any more. I had to remove iscsi and install it again...

rmsf -H 255/0/1.0.0.0 should work... It has done so for me in the past...

The NO_HW already indicates the disk is no longer available.

Yes, its working with -H option. Thanks for your quick response.
