You may be able to hex edit the LUN, and manipulate the VMFS header file, but this requires on-site support to perform this level of recovery.

I think it was the head because that's what would cause the datastore to become inaccessible from what I read in your other post. If the datastore stayed online then I'm assuming it wasn't the head.<br />
<br />
Do you have any documentation on this? It's my datacenter so I really don't need to purchase a support contract to have someone fly half way across the world to troubleshoot this.

Ah I found the volume containing the LUN was offline thus removing the LUN from view in NetApp. It's back online now but has other issues attaching to an OS but I'll make another post.<br />

Thanks

Or possibly create a dummy extent in order to mount datastore.<br />
<br />
One of two LUNs within a datastore was possibly deleted thus offlined the datastore. I need unmount and remount in order to recovery what's left by either creating a dummy extent or some other method.

How to mount datastore with missing extent?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
