Planned device removal is a device disconnection detectable by an ESXi host. You can perform an orderly removal and reconnection of a storage device.

Planned device removal is the intentional disconnection of a storage device. You might plan to remove a device for a variety of reasons, such as upgrading your hardware or reconfiguring your storage devices. To perform an orderly removal and reconnection of a storage device, use the following procedure:

1

Migrate virtual machines from the device you plan to detach.

See the vCenter Server and Host Management documentation.

2

Unmount the datastore deployed on the device.

See Unmount VMFS or NFS Datastores.

3

Detach the storage device.

See Detach Storage Devices.

You can now perform a reconfiguration of the storage device by using the array console.

4

Reattach the storage device.

See Attach Storage Devices.

5

Mount the datastore and restart the virtual machines.

To mount a shared datastore, see Mount Shared VMFS Datastores.

To mount an unshared datastore, see Mount Unshared VMFS Datastores.
