Upgrading the first metadata server engine

This topic provides the general steps for upgrading the first metadata server engine.

Context

Choose an existing subordinate metadata server to be the first metadata server to be upgraded. After you have completed the upgrade process and the metadata server has rejoined the cluster, you will transfer the master role to this metadata server.

Steps

  1. Prepare the metadata server engine for upgrade so that the SAN File System cluster continues to function while you are upgrading this metadata server engine. See Preparing the first engine for upgrade.
  2. Install all software on the metadata server engine. See Installing software on a metadata server.
  3. Restore the configuration settings. See Restore configuration settings.
  4. Set up the metadata server engine and validate that it is installed correctly by having it rejoin the cluster and ensuring that this metadata server engine has access to LUNs and volumes. See Setting up the metadata server.
  5. If you disabled the boot drive mirror, you can now re-enable the mirror. See Re-enabling the boot drive mirror.
  6. Set this metadata server engine as the new master, which includes performing a backup of the new configuration. See Setting the upgraded server as the new master.
