We have IBM eServer 345 that has been configured with two 80 GB drives on Windows 2003 Server; but we ran out of storage. We have just purchased two 320 GB drive and one by one replace the 80 GB drive and rebuild RAID 1 with the new 320 GB. Now the server has two 320 GB drives. How can we increase the storage capacity without having to rebuild the server from scratch? We have about 64GB of data to protect.
