Expand raid set h200

[wildchild]

Hi guys,

Between a rock and a hard place here , situation on site ;

R310 with h200, initial raid set raid 10, 4 * 250 gb.

Replaced the 250gb disks with 1tb disks, am able to see them in omsa as 1 tb, however virtual disk remains 480..

So the question is, how to expand the raid set ?
To be noted, server is about 6500 miles away, and doesnt have a idrac, nor a sensible onsite engineer.

Do have omsa running, and esx 5.

Now for the tricky part, data must remain

Hopefully anyone have an experience ?

any body any good ideas?
Called Dell , and their only supported way is to remove te RAID set completely , thus essentially destroying the data on it.

In the LSI world this is called online capacity expansion (OCE) and you would log in and redefine the volume to recognize the full space. Then you would force the OS to reread the volume. I'm not sure on the H200 card... But would definitely not do without easy access to a local tech.

None of the Dell raid controllers support expanding a virtual disk's size by replacing the drives (one-by-one-with-rebuilds) with larger ones. They only support expanding raid 5 and 6 (not 10, 50, 60) by adding 1 or more drives. Also, this is only possible if there is just a single virtual disk on the physical disks (not split into 2 or more virtual disks).

At a risk, you can re-tag the virtual disk by deleting it, and then recreating it and selecting not to initialize the virtual disk. I would not recommend doing this unless you have a fully tested backup of all your data on this disk set.
