I have a Dell PowerEdge with a RAID 5 array of 3 disks, and I want to add a fourth disk to it to expand the capacity of the volume.
I don't want to reinitialize the whole RAID 5, because I want to keep all the data on it and just expand it.
Can I do this with OpenManage while Windows is live, or do I have to do this on the boot menu while the OS is not mounted?
Here is a screenshot on OpenManage Server Administrator:
And also please tell me how to achieve this. Thanks!
