Move an Array from One Tagged VLAN to Another

The workflow below describes how to successfully move an array from one tagged VLAN to another without losing connectivity to the array. Using this method, there is always at least one path to the host, and downtime is avoided.

  1. Be sure there are at least two links between the host and the array.
  2. Untag one of the links.
  3. Move that link from the old host to the new host. The array is still visible on the old host using the tagged link, and is now also visible on the new host using the untagged link.
  4. Untag and move the second link from the old host to the new host. Repeat this until all links have been untagged and moved.
  5. Tag the links with a new VLAN ID, if desired.
