RAID Volume expansion
Posted on 2013-06-08
I have two clients with HP Proliant servers that come with an embedded software RAID controller (B110i). The controller is entry level so can only be configured for one array and two logical volumes. The current config is two mirrored 250GB HDD with two similar sized volumes.
I added two new 1T HDDs and then realised the controllers limitations.
So my question is around the easiest way to use the new HDDs.
Option 1 is to use my backup app BackupAssist which can perform a bare metal restore to different hardware. This is straight forward but I'm not sure how the volumes would be expanded. I'm thinking physical data location on the disk here. The server runs SBS2011 so I don't know if this would create unnecessary disk activity. Downside is I loose the 250GB HDD.
Option 2. This is my theory here. Copy off the data from the second volume, which is programs and Exchange mail database and then deleted the second volume from the raid controller and expand the first colume to use the newly freed space. Then add the 1T HDD to the controller as a second mirrored volume. Restart the OS in safe mode and expand the first volume so to include what was the original second volume and then initialize the new 1T second volume and give it the same drive letter and the original second volume. Then copy back the program and Exchange data and restart the server in normal mode.
So the question is that would both these options work. Option 2 is my preferred end state.
