It seems our VMWare and Datastores is broken.
2 ESXi vSphere 5 hosts
1 Starwind SAN
On ESX1, all datastores look fine and visible.
On ESX2, it can only see local storage.
- If you go to "Add Storage" it can see the SAN Datastores, but the only option is to Format the store, not to keep existing signature.
- Under Storage Adapters, all the paths are there and mounted (all showing same LUN values - same as ESX1)
- If you try to add a datastore which is NOT on ESX1, Keep Existing Signatures is valid but the operation fails with error "Cannot change the host configuration"
Prior to this everything was working fine - both hosts could connect to the datastores (clustered mode on Starwind is enabled).
ESX servers have been rebooted several times as has vCentre VM (Linux version)
The only difference is that the vCentre was moved to a different host - from ESX1 SAN Storage to ESX2 Local Storage so we could reboot the host and keep vCentre up.
Of course now we cant move it back because we cant add in the datatstores...
