After upgrading 3 Dell 6850 servers to 3.0.2 from 3.0.1, we have problems with iSCSI on 2 of them:
systems take a long time to boot
then they don't connect to iSCSI storage
LUNs became visible after a simple "rescan" on vmhba40 iSCSI adapter
Looking at vmkernel log, it seems a timeout issue during startup.
All was working well with 3.0.1.
An additional note: both affected servers have A05 BIOS version, unaffected one has A04.
AN IMPORTANT UPDATE: it works removing all adapters but one from vSwitch!
Peraphs, update to 3.0.2 introduced a problem with network load balancing and iSCSI.
I have the same problem.
Recently dual-connected Dell PowerEdge 1950 running 3.0.2
8 node cluster, 2 nodes don't have iSCSI LUNs after reboot. Do a rescan and they are there.
I also have 6850's but those are connected via FC over HBA.
Do you have standby vmnic in iSCSI vSwitch?
It seems that removing stanby NICs is a workaround. Unfortunately, VMWare support was unable to really assist me and call was closed without a real investigation
I'm pretty sure that it will be recognized as a bug in the next future!
