I am using Linux+SCST for many of my non-critical needs and it works great.
Recently, I built a new ESXi 5.0 cluster and can no longer add the iSCSI devices as a datastore. Mind you, I can see them under the software adapter as "mounted" under "operational state".
I have exhausted my resources on the SAN side of the equation (even going so far as to clone an existing installation that works fine) with no luck.
Are there diagnostics or logs that I should be using inside of ESXi to get more info on why this is happening?
