I have the following scenario:
I got a Cisco UCS server with a LSI controller. I needed to replace the controller for another one, same specs, different model.
I did the physical replacement, powered on the server. ESXi booted fine, but no datastore is showing up. The datastores are on the local hard disk. There is no remote storage.
When I try to re-add the datastore, I got 2 mainly options:
- Keep existing signature
- Assing a new signature.
I'm sure both will work, and I would go with the first one.
However, I would like to know the impact of selecting any of those options. Like, if I resignature, will that be the best since I'm using a new hardware for RAID controller?
Or would it not matter at all if I keep the same signature?
I've beenr reading about these 2 options, and for local storage they don't seem to do any difference, but would like to know somebody else thoughts.
I'm a little afraid of assigning a new signature.
Thanks.
