I first verified that my backup FreeNAS disk array was free of virtual systems and updated that system.
- Actually since I keep my backup disk array off due to power usage concerns (costs a lot) I first had to reintroduce the iSCSI storage to the Xenserver environment by “forgetting” and then reading as new storage and “reattaching” to the luns.
- I then migrated my Xenserver virtual systems disks to the newly updated FreeNAS system.
- After migrating the VM’s off my main disk array I then updated that version of FreeNAS to 9.10
- Now all my virtual systems are being migrated back to my main storage disk array and I will be able to turn off my backup storage array for energy savings until my next planned upgrade coming in the next few months!
