I am replacing a perc 310 raid controller with a H730P tomorrow on a ESXI 5.1.
I read these posts and it looks pretty straight forward:
Replace H310 with H710 - PowerEdge General HW Forum - Servers - Dell Community
LUN signature after RAID controller replacement
My question is I have a lower end Synology NAS and thought it would be safer to move the vms storage on that host to my NAS before I do the upgrade.
Then I can replace the card and if anything goes wrong everything is stored on the NAS. Then only the vms are registered on the host but not the data.
Then after registering the new LUN and re-signaturing it all I have to do is add the vms back from the NAS datastore and then move the data back.
Does anyone see an issue with this?
Thanks,
J
