Here is what I have:
1 Compaq server with a 4 bay storage cage. 3 drives configured as raid 5. 3 partitions configured.
I am out of space.
I have 4 new drives of larger capacity I wish to swap.
I also have a spare Compaq storage works tower.
I want to connect the tower to the server with the existing 431 controller (Can I have 2 connected? The external box and the internal drivecage to the same controller at the same time) With the 4 new drives in it. Configure the new array as a raid 5.
Then I want to boot to Acronis Migrate and copy the existing raid 5 over to the new raid 5 in the tower.
Then I want to shut it all down, move the 4 new drives from the tower to the internal cage. 3 old drives will be removed. Disconnect the tower. And boot up and all be the same as it was except I have more HD space. My concern is the RAID being recognized in the internal cage as it was created in the external tower. I do not know if raid array config data is stored on the disk or in the controller.
Can this be done?
Open to all suggestions except backup and restore from tape. I am doing all this to avoid that.
