How to remove Dead or Error iscsi targets from ESXi | VMware


Sometime we may find an iscsi target associated to an iscsi adapter being greyed out and marked as Dead or Error. In VMkernel log you may receive an error as given below:

WARNING: NMP: nmpDeviceAttemptFailover:658:Retry world failover device "naa.6090a05850f3465b871325e61b6af905" - failed to issue command due to Not found (APD), try again...

This is a result of an improper deletion of a LUN/iscsi target from the storage adapter.


Enter the host into maintenance mode (Just to be safe)

esxcfg-rescan -d vmhba3

Replace vmhba id with the id of your vmhba adpater.

Ensure that you are not receiving any errors by checking vmkernel log file

tail -f /var/log/vmkernel.log

Exit from maintenance mode

You may be required to refresh the storage adapters after the rescan.
