Cannot remove unmounted datastore

[hyvokar]

Hello!

We are running 2x esxi5.0 hosts with vcsa5.1.

We have been moving stuff out from our old HP EVA datastore to new ones. I still have one datastore I cannot delete from vcenter.

I can mount, unmount and browse the datastore, but for some reason, it cannot be removed. It gives me an error Call "HostDatastoreSystem.RemoveDatastore" for object "datastoreSystem-85" on vCenter Server "MyvCenter01" failed. And the Tasks say "An error occurred during host configuration".

There should be no active data on the datastore (last writes more than year ago).

Any advices how to troubleshoot this on?

Also, as a workaround, is there any harm done, if I simply unmount the datastore and after that unpresent and delete it from EVA ?

Thanks in advance

Try connecting directly to the host(s) with the vSphere Client and then remove. Also make sure to follow the instructions in VMware KB: Unmounting a LUN or detaching a datastore/storage device from multiple ESXi 5.x hosts

Hi!

When I log in to esx1 host, and try to remove the datastore, I get an error

Call "HostDatastoreSystem.RemoveDatastore" for object "ha-datastoresystem" on ESXi "esx1" failed.

Connected via ssh to esx1 host:

~ # ls /vmfs/devices/disks/ |grep naa.600508b400107d9a0000e000006e0000

naa.600508b400107d9a0000e000006e0000

~ # partedUtil getptbl "/vmfs/devices/disks/naa.600508b400107d9a0000e000006e0000"

Error: Can't have a partition outside the disk!

unknown

So can I just delete the partition

partedUtil delete "/vmfs/devices/disks/naa.600508b400107d9a0000e000006e0000:1"

and do I have to do this on both esxi hosts ?

Ok, so I'm a bit lost here.
