Products

Issue/Introduction

Symptoms:

• Have HA enabled on the cluster and are running vSphere 7.0  
• Datastore encounters a APD event ,In /var/log/vobd.log similar entries are seen:

2021-03-11T09:49:57.123Z: [APDCorrelator] 460296002450us: [vob.storage.apd.timeout] Device or filesystem with identifier [naa.600601607b477826e60ef95ed62e643f] has entered the All Paths Down Timeout state after being in the All Paths Down state for 140 seconds. I/Os will now be fast failed.

• In /var/log/fdm.log similar entries are seen:

2021-03-11T09:49:57.754Z warning fdm[2104475] [Originator@6876 sub=Election opID=SWI-3ab50c2a] IM reprts no locally accessible datastores

Environment

VMware vCenter Server 7.0.x
VMware vSphere ESXi 7.0.0

Cause

If an APD is introduced on all the datastores connected to a host, the FDM agent on the host will move into 'uninitialized' state. Due to this, the FDM agent on a host will not perform the VMCP operation (like terminating a VM). Hence, the impacted VM would not be restarted on any other host.

Resolution

This issue is resolved in VMware vSphere vCenter 7.0 U2c. See Download Broadcom Products and software
