Cannot remove datastore

[TomKalabis]

Hi,

i have 3 production servers on ESXi 6.0 3073146 and VCSA 6.0 u1.

I have new storage with 2 LUN - R5 and R10 (RAID), soo i migrated all vms from old storage Dell MD to new storage. But ! i have one problem.

I have one vm, which is migrated from old SATA2 (name of datastore) to new DX100_R10.

In vcenter on summary tab of VM i see storage SATA2, but if i browse datastore SATA2 - sata2 is empty, any config file for my vm. Any connected .iso.

But, the most interesting think is, that if im connected directly to esxi host, where is my problematic vm i see only correct datastore DX100R_10

So i unmounted old datatore SATA2 from all of 3 hosts, now i cannot delete it !

err is: The resource xxx is in use.

I tryed:

restart vcenter - same problem.

remove all 3 hosts from vcenter and add it to vcenter - same

Use the following KB article to restart the management agents on your hosts.

https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=10034...

Be sure to go into HA and turn off host monitoring before you restart the agents or vCenter will think the host failed.

Hi,

if im connected to vcenter and i go to the inventory>datastores i see old SATA2, but no actions available, no unmount, no delete...

so on all 3 host i see only  new storage, whitch is correct. but i see old storage in vcenter

Is it like that on all hosts? Can you SSH into the hosts and run ESXCLI storage list?

Is it possible to re-add the datastore and try removing it cleanly?

[TomKalabis]

All 3 host see only R5 and R10 ( + one host see his own local storage )   checked via ssh

i think, that problem is in the vcenter, so i restarted it, but same situation.

When im on the Datacenter - Datastores: 4

When im on the Cluster - Total Datastores: 3

I re-add the datastore and remove it - no problem here, but old i "shortcut" in vcenter still exist.

That is genuinely odd.

Hi,

Does the VM that you moved have a snapshot in place? Was it possible that you had a ISO connected at the time you created the snapshot?

If this is the case then the Snapshot will be aware of this in case you want to revert.

If not the ignore the ramblings 🙂

Kind regards.
