Hi,

have you locked down the initiator group in nimble storage to the specific iqn?  

also have you check that the boot volume iqn target is correct? i had a similar issue before, where i putty'd into nimble storage to get the iqn target info, and i had smaller putty window. the iqn target info was wrapped to the next line & i only copied part of it & i got a similar error to the above.

hope this helps.

yes this was working just fine prior to vmware patch updates. I dont think vmware patches would have anything to do with the boot from san to the nimble. 

Still cannot boot. IQN looks fine

from iscsi_get_config

I see this error 

ISCSI_TARGET_LOGIN_ERROR

IQN matches up with the one in nimble

IQN: iqn.2007-11.com.nimblestorage:esx1-bootvolv53e2c6e4ade1c307.00000032.fe0305e3

check the initiator group on nimble and the IQNs have full access to this bootvol
