raid expansion on proliant dl380g4

Good morning
I have a HP Proliant DL380 G4 server. The initial configuration of the server was a Raid5 array made of 3 hdds and one spare. I added another to drives to the array and performed raid expansion, which finished succesfully. The next step was to extend the logical drive on the two drives that were added to the array.
For about 10 days I have status message 785: Background parity initialization is currently queued or in progress on logical drive 1 ( RAID 5 in array A). If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve.
I see the free space in the disk management console. The server works fine but the logical drive extension did not take place.
what can I do?

In a cluster configuration, parity initialization of LUNs will not finish. o Parity Initialization is done when the controller is idle. The cluster software will poll the controller continuously, preventing parity initialization from finishing. Disable clustering SW until this is done.

Try to reseat one of the new drives, the controller will sense the reseat and should initiate a rebuild. This could trigger the parity initialization.
