What is PDL and APD?
There are two distinct states a device can be in when storage connectivity is lost; All Paths Down (APD) or Permanent Device Loss (PDL). All Paths Down (APD) is a condition where all paths to the storage device are lost or the storage device is removed.
What is datastore APD?
A datastore is shown as unavailable in the Storage view. A storage adapter indicates the Operational State of the device as Dead or Error. All paths to the device are marked as Dead. You are unable to connect directly to the ESXi host using the vSphere Client.
What will happen when all paths down APD event occurs for the software Fcoe storage?
When the All Paths Down (APD) timeout for a storage device connected to your ESXi host expires without the device being recovered from the APD state.
What is datastore with PDL?
PDL. PDL (Permanent Device Loss) is an unrecoverable loss of accessibility that occurs when a storage device reports the datastore is no longer accessible by the host. This condition cannot be reverted without powering off virtual machines. APD.
What is host isolation in VMware?
Host isolation response determines what happens when a host in a vSphere HA cluster loses its management network connections, but continues to run. You can use the isolation response to have vSphere HA power off virtual machines that are running on an isolated host and restart them on a non-isolated host.
What is VMware proactive ha?
Proactive HA is a new feature integrated with server vendor monitoring systems. The cluster must use vSphere DRS for correct Proactive HA. For example, Proactive HA can help you when there is a problem with power supply. All VMs are moved to other hosts, and you have a chance to repair problems with the hardware.
Has entered all paths down state?
The messages indicate that the system has turned on a timer that allows your VMware ESXi host to continue retrying attempts to re-establish connectivity with the device for a limited time period. By default, the APD timeout is set to 140 seconds.
What is vSphere DRS?

VMware HA and vMotion are two interwoven processes; VMware HA is dependent on vMotion. The technology of the migration process is designed so that there is no downtime and the user does not even notice these actions.
What is difference between HA and proactive ha?
vSphere HA is a technique to protect virtual machine in case of Hardware failure of Host machine. HA cluster in vSphere 6.5 is Proactive, with the help web client plug-in by OEM vendors (Cisco, Dell and HP). This Plug-in monitors Network, Power, Memory, Local Storage and Fan of the Server.
When is APD iConnect going to be implemented?
