I have two HP DL380 Gen9 Servers with H240ar RAID controllers. One is for production and the other is for dev/staging.
I'd like to build up two physical drives in RAID 1 on the dev server then put those drives in the staging server and have that server recognize the logical drive. If this worked, this would require the least amount of down-time to deploy files. Is this possible?
As I experiment with swapping in different drives, the controller doesn't recognize the drives unless it's the same drives. Does anyone know what data is stored on the controller? I thought it might save the logical drive letter and the associated drive locations (Port, Box, Bay), but then other RAID 1 drives built from the same controller should work, but instead I get an warning as the computer boots up and the two drives show as unassigned.
UPDATE: If you put the two physical drives in another computer with an H240ar, the logical drive will not appear based on the data on the physical drives. So, I think there is some metadata being stored on the controller.
ssacli to create a new logical drive with the same two physical drives that were used in the other system and the partitions and file systems were in tact on the other system.
I still worry that without a good understanding of the metadata and where it is stored, I will not be able to predict what I can and can't do reliably.
