I have a customers server installed late last year with 3x 300GB SAS hard drives in a RAID5 configuration.
This server has onboard M5110e ServRAID controller with both the 512MB Cache/RAID 5 Upgrade and Battery Kit installed.
Server is running Windows Server 2012 in a host / Hyper-V configuration.
We need to expand the storage capacity so want to add 2x 300GB SAS hard drives, expand the existing RAID5 array to include these hard drives so I can then expand the Windows data volume (the host server is configured with 2 drive volumes, C: & E:) to include the additional storage.
From what I've researched this is possible(?) but I'm not able to find any clear documentation on this process. I tried calling IBM support but this was a waste of time, the person I spoke to wanted to log a service request for a fault that doesn't exist and doesn't seem to undersand what I was asking.
So I'm hoping there is someone here with experience in this that can offer some advice and/or point me to some documentation on this.
First question though, is it possible to expand a RAID5 array without data loss?
Of course I will be doing multiple backups just in case ;)
Thanks in advance for your help :)
