Initiators are the same as the crashy storage, QLA2462. Here's what lspci shows for them if it helps:

I will work on getting storage presented from one of the problematic systems with the emulate_caw=0 setting, can you be more specific on where this should be set?
emulate_caw is a backend device attribute. It can be changed for each backend device within the configuration file before restarting the target service, or in /backstores/iblock/$DEVICE using targetcli.
Note that this will need to happen before the ESX FC initiator connects, and performs the LUN SCAN to query if COMPARE_AND_WRITE is supported or not.
