Hi Gerry,
It would be helpful to see a few lines of debug just above the error to better see what may have triggered it and whether it is related to the additional SR you are adding.

Assuming you are adding a second internal SR to be managed by iscsi-ha, there are a number of files that need to be edited to make that work. There are several threads on this forum with the detailsa. In short, you will need to update the drbd, lvm, iscsi-ha and tgt config files.

This post has all the steps.. It's a bit of a long post, but all the info is in there. The most common issue I have seen with adding SRs is that users don't properly edit the XML in the TGT targets file.
