Hello James No, you will not be able to accomplish the task that way. If you swapped out the current drives for larger drives then the array would still be the same size. You could accomplish this in one of two ways. You could create a second array with the additional space that is added with the larger drives(Slice array), or retag the array to get the controller to rewrite the meta data. Unfortunately the SAS 6 does not support either of these methods. The SAS 6 forces an initializes(low level format) whenever an array is created so you cannot retag the array, and it will not allow the creation of multiple virtual disks on the same drives(slicing). To accomplish this you will need to backup the data, delete the array, recreate the array, reload the OS, and restore data from backup. Thanks
Hi, We have a PowerEdge 200 server (2 drive bays) with a SAS 6/iR Internal Controller.  The server currently has two 500GB SAS drives configured as RAID 1.  We are running out of disk space on this RAID set and would like to change the 500GB drives for 1TB drives.  Is it possible to swap drives one at a time, rebuilding the mirror and then increase the RAID size so that the full size can be seen in Windows? Are there better solutions changing the drives we have for larger drives? Thanks James
