Yes, this filer was running 8.1.2 7-mode and upgraded to 8.2.2. The -i option should be available in diag mode for a "lun show"

I had a full LUN "disappear" once with similar symptoms as you're seeing - although of course it couldn't be mounted by the host but the space was still being used by the LUN in the volume and aggregate. It was an Exchange LUN that was completely full during an upgrade. When the filer rebooted, the LUN couldn't register when the controller came back up. NetApp Support ran some commands in diag mode that at least showed the LUN still existed.

You might try this to get some visibility into the LUNs:

> priv set diag

> lun show -i <lun_path>

Can you do the command without the path, but with a -volume v_fc_rdm_adhoc1?

Hello,

this had be the path:

/vol/v_fc_rdm_adhoc1/l_fc_rdm_adhoc1

But the command returned: There are no entries matching your query.

Only the Volume (v_fc_rdm_adhoc1) is there without the LUN (l_fc_rdm_adhoc1) – thats the problem.

CLI and GUI shows the same…

Can you enter the command lun show -vserver xyz -path xyz -instance? Replace xyz with the name of the vserver and the path to the lun.

What version of data ontap?

Hello,

we have a LUN that is suddenly „invisible“ by our Netapp Filer. The Volume has the Capacity oft he LUN – thats seem OK,

but the LUN is missing. The Host (it is a ESX with a Windows Server) see the LUN and ist mapped to the Windows

Server and in the Server the volume has a letter and can handle files.

What can we do, so the LUN is back and visible. The LUN is not in the Systemmanager and not in the CLI. In the Volume

is a file that seems the LUN, but someway is called „stale“. I wish the Toasters can help…
