Inactive (unmount) LUN

[Cloomger]

Hi all.

Pls help. I have this problem on my esx host

[rcporto]

Do you want mount the datastore again ? Did you already try right click and Mount ? The logical volume on storage array is online and there is SAN connectivity between the ESXi host and storage arrays and the logical volume is mapped to ESXi host ?

And check this blog post: VMFS datastore showing greyed out, inactive and unmounted | Robin CM's IT Blog

Thanks for the link, but  i read it before post her.

I think problem with datastore zoning...

Hi Cloomger,

Could you please go to Home > Inventory > Datastore Cluster view and select the Inactive datastore. Click on Virtual Machines tab and see if there are any inactive VM's listed here. If there are inactive VM's remove them from inventory.

Now, go to Hosts & Clusters view > Right click on the cluster and rescan for datastore. Let me know the output.

Guys, problem is actual((((

Could you please get the naa.id of the inactive datastore and verify whether it is actually listed under Storage adapters ?

Make sure the lun is no longer active on the SAN(AKA the ACL's on the SAN for that LUN have been removed) and the zoning on the fibre switches has been removed as well.  You shouldn't need to remove the zoning, but it can't hurt.  Once the SAN remove's access to that LUN for teh ESXi hosts it should disapear after a re-scan of the storage controllers.
