The Vitual SAN host cannot be moved to the destination cluster

The Vitual SAN host cannot be moved to the destination cluster: destination cluster vim.ClusterComputeResource:domain-### is Virtual SAN disabled

 

To resolve the problem we did the following:

 

Verification:

  1. From Storage inventory view in vCenter, verify a VSAN datastore still exists.
  2. If it does, Putty into the ESXi host or access it via its ESXi Shell & execute the command:
    esxcli vsan cluster get
  3. If results appear, proceed to the solution …

Solution:

  1. From previous command line (SSH or ESXi Shell) to the affected host, execute the following command:
    esxcli vsan cluster leave
  2. Now add the host to the existing Host Cluster…

Both Verification and Solution steps together look like this:

Clearing the ARP cache table in ESXi 5.5

For example, to delete the ARP entry for address 10.103.0.10:

  1. Connect to the ESXi 5.5 host using SSH.
  2. View the current ARP table using this command:

    # esxcli network ip neighbor list

    You see output similar to:

    Neighbor      Mac Address        Vmknic    Expiry  State  Type
    ------------  -----------------  ------   -------  -----  -----
    10.103.0.10 xx:xx:xx:xx:xx:xx   vmk0     908 sec        Unknown
    10.131.0.179  xx:xx:xx:xx:xx:xy   vmk0    1062 sec        Unknown

  3. To delete the ARP entry for address 10.131.0.103, run one of these commands:
    • # esxcli network ip neighbor remove -v 4 -a 10.103.0.10
    • # esxcli network ip neighbor remove --version=4 --neighbor-addr=10.103.0.10
  4. View the ARP table again using this command:

    # esxcli network ip neighbor list

    You see output similar to:

    Neighbor      Mac Address        Vmknic    Expiry  State  Type
    ------------  -----------------  ------   -------  -----  -----
    10.131.0.179  xx:xx:xx:xx:xx:xz   vmk0    750 sec        Unknown
