Recently we have been getting the All-Paths-Down (ADP) error on our VMware servers.

Jun 10 16:58:54 vmkernel: 5:14:36:03.462 cpu1:4349)WARNING: NMP: nmp_DeviceAttemptFailover: Retry world restore device “naa.600601606d022300aa855779fe51df11″ – no more commands to retry

So far we are still looking for a solution from VMware and EMC.

Here is a link we found that have similar issue, but it didn’t solves our issue:
