We have a legacy Fujitsu Server with just 4x HDD bays (4x disks) – we have 2 mirrored arrays and one of the array is small and we need to upgrade the disks with larger disks but retaining all the data inside.
As far as I know the below procedure should work well:
– TAKE A FULL BACKUP TO AN EXTERNAL USB DEVICE USING WINDOWS BACKUP
– TURN OFF SERVER AND TAKE OUT THE TWO DRIVES WHICH ARE GOING TO BE REPLACED
– WHILE SERVER IS OFF, REPLACE WITH LARGE HARD DRIVES (2x IDENTICAL DRIVES)
– TURN ON SERVER
– GET INTO RAID CONTROLLER AND MAKE SURE THAT NEW DRIVES FORM A NEW MIRRORED ARRAY – OTHER ARRAY HOSTING OS IS NOT TO BE TOUCHED
– SAVE CONFIG AND REBOOT SERVER
– ONCE SERVER BOOTS UP TO RECOVER ALL THE DATA FROM THE BACKUP TO THE NEW DRIVES RETAINING ALL NTFS PERMISSIONS ETC FROM THE OLD DRIVES
Its been a long time since I did the above but as far as I know it should work well – can you guys confirm please?
