I need to upgrade disks in a Dell PowerEdge 2800 server. The server is currently a RAID1 (hardware RAID) of 2 X 36GB SATA Drives. I need to replace the disks with 2 x 146GB SATA disks. I need to do this with out re-installing the OS and a minimum possible down time as it is a clitical sort of server. Dell's website was not very helpful. My question is: can I replace each of the drives with a bigger drive, recreate the array each time - end up with two bigger drives only half used - and then expand the logical disk to cover all the new disk space? I can do that in hp servers. But don't know in Dell. Any help is appriciated. Sorry to go on!
