Hey,
All of my iSCSI LUNs are having an issue being mounted by my hosts. This is a new host with a new iSCSI SAN. I tested it in dev with 5.5 and everything went well. The only difference is the hardware that dev and production run on. Both use Software iSCSI adapters, but the production environment has an Intel PRO 1000 with TOE support. Not sure if this is significant enough to warrant mentioning it, but hey wouldn't want you to jump through hoops, etc.
As follows:
iSCSI target is in the same subnet
iSCSI Software Adapter has two NICs, each from separate vSwitches that are dedicated to the iSCSI software adapter. Both show "Compliant" and "Active"
The paths are set in Round Robin per VMware best practice for multipathing.
had to delete all LUNs and recreate with 512 block size.
