SOLVED XenServer ISCSI multipath wont connect after 9.2.1.8 to 9.3 upgrade

[Neil_McCarthy2]

I have had a look at this since the RELEASE, and apart from the fixed issue with the generation of the ctl.conf file my testing has not encountered the issues that I experienced with the BETA versions.

I have successfully upgraded from 9.2.1.8 to 9.3-RELEASE, and had connection issues as before. I have not tested this on a multipath environment yet.

I followed the Citrix article:

As per: http://support.citrix.com/article/CTX118641

Here Goes from my test machine:

SCSIid is from the probe

Then repair in XenCentre.

Thanks! I've saved this off for when I upgrade (perhaps this next weekend).
