The iSCSI LUNs go offline when a restart is done to Windows 2003
Hi all,
I have an issue here. Whenever the Windows server is restarted, the iSCSI LUNs go offline. Then i should manually get them online again.
Anyone have experienced such problem, kindly advise.
Thank you

For your specific issue, when you first login using the Microsoft iSCSI Initiator, you go to the Target tab, highlight a path and click "Log On" - on the first screen that pops up, you need to check the box called "Automatically restore this connection when the system reboots"
You also need to check the other box, "Enable multi-path" if you are using PowerPath 4.6 or higher.
Next click on the "Advanced" button and on the next screen select each of the three drop downs and select the "Local Adapter" for "Microsoft iSCSI Initiator", then for "Source IP" select the NIC on the server that you will be using for iSCSI traffic. Lastly, for "Target Portal", select the entry presented.
All the above is outlined in the Host Connectivity guide.

PLease let me know your configuration. You have to use iSCSI HBA or choose Basic disk.

Ohhh..i see what you are saying ..you can not use dynamic disk with software initiator (it may work but not supported by Micro$oft).

Thank you for your replies.
I did a small test, created a LUN and chose it to be Basic drive. Then had a reboot. The Basic drive was ok and reconnected automatically. But, the Dynamic went offline and I had to reconnect it manually.
Kelleg,
I read your instructions and I will check them today hopefully.
Guys,
I have one concern regarding basic drives. Up to my knowledge, the drive should be dynamic in order to expand it. But, if it was Basic, I should use the command diskpar. I faced this issue with cluster LUNs as cluster services do not support dynamic disks. So, should the scenario be the same here?
Best Regards,
Rami
