Hi,
Our server (ProLiant ML350 G6) has a raid 5 array with 4 disks of 300Gb. We are getting short on disk space.
Can I replace the disks one by one with a type of 600GB? Or what is the procedure to fix this?
Thanks for your answers. Ben.
Solved! Go to Solution.

SolutionSure you would need to let the rebuild process complete between each drive "Upgrade". Then afterwards, it would be wise to fire up the SPP disk (or use windows) to create a new slice for the expanded array size and SPAN or just create another drive letter/lun for your application!

Re: increase disk space in a raid 5 array on a ProLiant ML350 G6
When you've replaced all of them you can do an array expansion to grow your logical array and use the rest of the space, or if you like create a new logical array using the new space.
The choice is yours, although online expansion requires a battery backed cache module.
You can speed things up a little bit by modifying the priority of rebuild and expansion tasks to higher priority, which will slow down normal access a little. If you want to keep the OS running as best it can, set the rebuild to low priority, but rebuilding 300GB of data will take a while at low priority. I think at high priority I've seen 300GB rebuild in about 90 minutes.
