Hi all,

After some troubleshooting I have check the same LUNs were presented to other vCenter and hosts.

After removing and set the proper permissions and configurations, we can see the LUNs again in devices, and also if I try to add a Datastore the LUNs are visible to add again(only as new).

Normally the hosts should pick up the datastore and put online and available, but for some reason they did not, so if I try to add the LUNs again as a Datastore this will reformat and destroy all data(there is still VMs in it), so my question is, how to add the LUNs again without formating them??

One example:

/dev/disks # ls -l | grep naa.60000970000292603672533030333136

LUN 4 and active, cant find any issues here. So host should add the LUN in the host as datastore automatically,

So how can I add this without formating the LUN?

Thank You
