Can anyone help with this dilemma.
We have 3 identical HP 5.1 ESXi hosts with onboard Broadcom NICs connected via iSCSI to a shared iSCSI storage.
All was working fine until system board failure on Host1 failed POST test.
HP replaced system board with on board NICs( when I was on leave) and all boots up fine loads ESXi from local storage OK.
All looks fine except this host can no longer see the existing iSCSI storage
Network connectivity is fine from the new host to iSCSI target, I can vmkping from Host to iSCSI target IP address fine across the dedicated iSCSi network.
Also strangely I have since added a further iscsi datastorage on the same device and this is seen by all 3 hosts!
Can anyone explain how to get Host1 to see the iSCSi datastores rather than rebuilding the host.
A rebuild for a simple hardware replacement seems drastic.
I have been assured by HP that the motherboard is the same so the drivers for the onboard Broadcom NICs should work, ( which they do for the new datastore)
I presumed there must be some link between the MAC address of the old failed NICs and the iSCSI address that maybe embeded in a config on the ESXi host.
help please
