Re: Upgrade Hard Drives in Raid5 configuration
I guess you have a Smart Array controller in your ProLiant ML370 server. As far as I know you can not just replace the disks one by one and then have free space in the array(of disk drives). The reason is because you can mix different sized disk drives in an array, but the controller will treat all disk drives as having the size of the smallest disk drive.
I am afraid you have to backup your data to a different disk or tape first. Then you delete the logical drive and remove all disk drives through ACU (Array Configuration Utiliy).
Now you pull the disk drives one by one a little out of the bay until it looses power and give it some time to spin down. After a minute at most you can pull them out completely and plug in the bigger disk drives. You create a new array(of the disk drives) and slice a new logical disk out of the array. Now you can restore your data to the larger logical disk and enjoy the additional space.

Re: Upgrade Hard Drives in Raid5 configuration
[*] I only have little experience with an old version, but I still use it for boot disk backups/restores.

Re: Upgrade Hard Drives in Raid5 configuration
It is possible to replace the disks one at a time. I would still advise that you have a full backup just in case. All that you need to do is replace the 18GB disks with your chosen capacity drive one at a time and let the array rebuild. Once the array has rebuilt swap the next one and so on. Once the last drive has rebuilt you will be able to use ACU to configure the unused space.
Cheers, Mike.

Re: Upgrade Hard Drives in Raid5 configuration
That would be great. Still, everyone I have talked to about the procees you descrided say it does not work that way. Before I try it I too would like to see some documentation about it. I may try this on another server to see how it works.
