MSA500 query - Extend and Expand


Currently i have a MSA30 box connected to a MSA500. I'm planning to put in 6 x 72GB hard disks into the MSA30 and expand a current array which a logical drive of 100GB. Is there an option whereby after i expand my array, i can do a extension of the current logical drive?

From what i understand, even if i'm able to do extension on the current logical drive, at the windows OS level, the extended partition will be shown as unused partition. Am i correct on this portion?

Is there any ways to make the OS see the extended partition as part of the disk??

Hi Leonard,

Yes. You probably need to use diskpart, although you don't say which version of Windows you're using.

Take a look at this Microsoft article:

Hope this helps,

Hi Leonard,

You can either extend the current logical drive within the array, or create a new logical drive.

From the Windows side of things, if the volume you want to extend was created on a Dynamic disk, then you can extend the volume onto the new logical drive (windows unallocated space) that you create in ACU.

If its your C:, System drive or it has a pagefile on it, then you cannot extend it Im afraid.
Limitation of the OS...
