Cleanup after wrong mask / unmask action

[scheltema]

Hi,

I have a issue on grayed-out and inactive datastores on several hosts. This is the result of a wrong mask / unmask action of the storage admin.

I now have datastores of datacenter A visible in on hosts of datacenter B (they are grayed-out and inactive), but because the datastores belong to a storage cluster with Storage DRS and SIOC enabled I cannot " unmount"  these datastores.

Is there a any way to get rid of the mess caused by the mask / unmask action ?

Any help or tips are really appriciated.

Thanks in advance,

Thanks grasshopper,

Indeed all that was left to solve the issue was a host reboot.

1 down, now of to the remaining hosts (a lot)
