Recently one of our VCenter 6.7 got crashed & services were not accessible, I spent hours but couldn’t restore it. To save time in further troubleshooting we removed the VC from the esxi server . Few Esxi servers were managed by this Vcenter. I logged in to each ESXI server & in Actions I selected “Disconnect it from Vcenter“. Afterwards when new Vcenter (VCSA-7) got installed , all esxi were added successfully , But one of the ESXI server was showing some errors, therefore I removed it from the Vcenter, & when I tried to add it again to VC , following error appeared
Datastore ‘M5-11.10–8TB-raid10’ conflicts with an existing datastore in the datacenter that has the same URL (ds:///vmfs/volumes/5d810e33-e56c55bf-71be-0894ef440178/), but is backed by different physical storage.
At VCenter I was seeing below
When I right clicked on this data store, DELETE/MOUNT/UNMOUNT option were greyed out as well. How can I remove this inaccessible data store?
From the Vcenter, I Browsed that inaccessible datastore , & clicked on VMs tab, it was showing one VM which was moved to another esxi host in the past, I edited that old VM on that esxi server , and removed the mounted ISO (which was pointing to the affected vm esxi server) , afterwards, the inaccessible datastore disappeared automagically, and the Esxi got re-added in VC again smoothly.
Sharing is caring !
