Hi Deepak, Robert

I could later do mkfs and then mount the lun.
I could see them in fdisk -l.
"That was gr8."

I also tried creating files and writing to them.
didnt do far, as the Luns disappeared after some time.
Might be some issue with the Keep alives.
still trying to figure out.

Thanks & Regards,
Hansraj
