VMWare Datastores Help

It seems our VMWare and Datastores is broken.

2 ESXi vSphere 5 hosts
1 Starwind SAN

On ESX1, all datastores look fine and visible.

On ESX2, it can only see local storage.

- If you go to "Add Storage" it can see the SAN Datastores, but the only option is to Format the store, not to keep existing signature.

- Under Storage Adapters, all the paths are there and mounted (all showing same LUN values - same as ESX1)

- If you try to add a datastore which is NOT on ESX1, Keep Existing Signatures is valid but the operation fails with error "Cannot change the host configuration"

Prior to this everything was working fine - both hosts could connect to the datastores (clustered mode on Starwind is enabled).

ESX servers have been rebooted several times as has vCentre VM (Linux version)

The only difference is that the vCentre was moved to a different host - from ESX1 SAN Storage to ESX2 Local Storage so we could reboot the host and keep vCentre up.

Of course now we cant move it back because we cant add in the datatstores...

Any ideas?

do the following at the console or remote via SSH

~ # esxcfg-volume -l
VMFS3 UUID/label: 4cc89503-f054d0d4-2865-00221958e471/nas3-vmfs
Can mount: Yes
Can resignature: No (the volume is being actively used)
Extent name: naa.600140588e9bab7d2b7ed4b53dadc1de:1     range: 0 - 1048319 (MB)

and then using UUID or friendly datastore label

esxcfg-volume -m 4cc89503-f054d0d4-2865-00221958e471

or

esxcfg-volume -m nas3-vmfs

Before I do that - is running vCentre on local storage supported? I.E how does it see/manage the other ESX servers if its not on SAN storage?

Yes, vCenter could be running on a standalone physical server with NO access to the SAN. Its the hosts that are configured and connected to shared storage.

That worked.

So now on ESX2 the VM's are showing, but a lot of them have red !'s on them?

what does the alert state for the VM?

Do you have a Cluster and use HA?

Oh!

So why did this happen, and will we need to do this everytime we reboot etc?

this can happen on vSphere, the servers forget or do no mount correctly the iSCSI LUN, we have seen it in all versions, but seems to occur more often in 5.0.

you should find it mount normally, but you now have the fix or workaround if it does not.

check if running latest ESXi 5.0 build and Starwind iSCSI builds as well.
