  • 1.  Add existing datastore to new ESXi host

    Posted Oct 17, 2013 11:55 AM

    Hello,

    Just wanted to double check one very simple and common thing.

    Currently I have one two-noded vSphere (ESXi 5.0) cluster plus one single host (same ESXi 5.0). All three hosts are connected to the same single shared iSCSI datastore. If I will add one more ESXi host which will have access to this same iSCSI datastore (including permission from the storage system side) this will NOT damage any existing VM files on this datastore? When first rescan operation completes after adding this new host this host just will have regular access to the existing datastore and after that this host can be added to the existing cluster - am I right?

    Thanks in advance!

    Yes It suppose to have the same access and same data's. Microsoft iSCSI target 3.3 will support 16 initiators.

    Hi and welcome to the communities,

    yes you can add your new host to the iSCSI Storage without any impact on the extisting VMs and add the host to the cluster.

    Hi Nikolay84,

    Welcome to the community.

    Yes you go ahead and do it.

    Once you add the datastore, the host will scan and see if it is formatted with VMFS and it will add it.
