ISCSI SETUP ON HP-UX

[Carlo Henrico_1]

Hi All

I have been trying to read up on the forums and elsewhere but am getting more confused as I go along.

I have an HP-UX 11.23 server and have installed the iscsi initiator. We have loaned an intel-based storage system which has ISCSI on it (to do a POC). I have done all kinds of things on the HP server to try and access the storage system but am now more confused than ever.

obelix2:/ (root) $ iscsiutil -p

Please help. A step-by-step dummy guide would be appreciated please!

Thanks

...this being one of the confusing pages I have been to.

[Carlo Henrico_1]

...the last 2 steps being:

obelix2:/ (root) $ /usr/sbin/ioscan -H 255
H/W Path Class Description
=================================
255/0 iscsi iSCSI Virtual Node
obelix2:/ (root) $ /usr/sbin/insf -H 255
obelix2:/ (root) $ iscsiutil -p -O
obelix2:/ (root) $


No errors but no success either.

Hi Carlo,

Same thing i have simulated on 11.31, same behavior i am getting, I am working on it, and will come back ASAP.

Thanks!

I rebooted the system and run these commands and my disks are showing.

#PATH=$PATH:/opt/iscsi/bin
#iscsiutil -a -I 192.168.2.105 -P 3260
#iscsiutil -p -D
#ioscan -H 255
#insf -H 255
#iscsiutil -p -O
#ioscan -fnC disk

check the iswd process is running?

# ps -ef|grep iswd

Hi Asif

I have also done all the and that process is running.

I do however see the following in the syslog:

Oct 13 13:18:53 obelix2 vmunix: 255/0: Invalid iSCSI Name format (iqn.2008-10:dss.target0) received from the target.

Carlo

[Asif Sharif]

Oct 13 13:18:53 obelix2 vmunix: 255/0: Invalid iSCSI Name format (iqn.2008-10:dss.target0) received from the target.

--> Invalid iSCSI Name format (iqn.2008-10:dss.target0)

Verify that the iSCSI Name is valid.

The iSCSI Initiator Name or iSCSI Target Name is referred to as an iSCSI Name. The iSCSI Software Initiator configures a default Initiator Name in the "iqn" format. If you have changed the Initiator Name from its default using iscsiutil and the Initiator Name is in an invalid format, iSCSI login negotiation could fail leaving target devices inaccessible from the HP-UX host.

http://docs.hp.com/en/T1452-90012/ch06s02.html

[Carlo Henrico_1]

Ok, change the iqn ID and now gone a step further:
obelix2:/ (root) $ iscsiutil -p -O

which it did not show erlier, and no more errors in the syslog.

The next step ioscan -fnC disk still does not show it...

Any other ideas?

[Asif Sharif]

post the output of this command,

# ps -ef|grep iscsi

Hi Asif

Here too is the exact output of the above commands, maybe you can determine from them which one is going wrong...

Run this process and then try...
#/opt/iscsi/bin/iswd

# ps -ef|grep iscsi
root 5023 1 0 12:25:44 ? 0:00 /opt/iscsi/bin/iswd
