I have a Dell PowerEdge server with the PERC 4e/Di RAID Controller. I have 2 disks in a RAID-1 array for the OS, plus 4 - 73 GB drives in a RAID-5 array for data. I've added 2 additional 73 GB drives to the RAID-5 array. Using the Dell OpenManage Server Administrator, it reconfigured the array and after several hours of rebuilding it now reports the virtual disk as ready with a capacity of 341 GB which is correct. However, Windows (Server 2003) still reports the original capacity of 204 GB. Do I still need to "ititialize" the new array to make all the drive space available? I know that doing so will wipe out my existing data.
