I would like some expert advice on my plan to upgrade one of my servers:
I have a HP Prolient DL360 G5 server that has all of its 6 hard drive bays used in a RAID5 array. Its running windows 2003 R2. We use this server for our document management system and it will run out of space in a few months. My request for a migration to a completely new server has been declined so I have to upgrade the one I have. I plan to buy 6 larger hard drives and upgrade as follows:
1>backup everything on the server using windows backup onto an external USB hard drive
2>remove the existing hard drives and put them somewhere safe.
3>Install new hard drives in a RAID5 config and partition as necessary (same partitions as before just bigger)
4>Install basic windows 2003 R2 installation
5>Restore backup into original locations, with original permissions using windows backup
6>Reboot and apply the latest prolient support pack (HP drivers for servers)
If the restore doesn’t work I should be able to slot my old hard drives back into the server and because the RAID array info is stored on the disks as well as the controller (for disaster recovery situations) I should be back to where I started.
Please critique this plan and tell me any issues I am likely to encounter before I attempt it
Thank you experts!
