You don't have to wait for the rebuild to complete. You can add the additional 13 drives before or after replacing the hot spare. No need to wait.
I have a CX4-240 that has a faulted disk which I will be replacing. I also have to install 13 disks. My question is can I add disks while the replaced disk is rebuilding or do I have to wait till it's rebuilt. Or can I add the 13 disks before replacing the faulted disk? I'd really like to only make one visit to the site.  cheers Daren
Adding disks to CX4-240 while currently rebuilding a disk?
