We had one ESX 6.0 server and one 6.7 and both were connected to a Dell MD1200 enclosure. Both could see the shared storage and both could read "Dell-DAS" datastore.
I vmotioned all VMs off of the 6.0 server and put 6.5 on it we now have one 6.7 and one 6.5.
When I reconnected the storage, the 6.5 could NOT see the "Dell-DAS" datastore.
An on-site tech did a new install of the OS for the 6.5 box and now the 6.5 box can see "Dell-DAS" but it's named "Dell-DAS(1)". Of course the data is the same, but still, this isn't right.
I'm trying to sort out what I did wrong and I'm striking out.
Can someone kindly point me in the right direction please?
Thanks
