procedure to re-image existing rpa in cluster?

I am having to go through this same procedure.  This is what I got back from the Dell SE.

• Burn the ISO for the existing code level of RP 4.4.0.1 onto a bootable DVD, and reboot the RPA with it loaded:
  ftp://ftp.emc.com/pub/rcm/recoverpoint/4.4/_oldCode/rel4.4.P1_d.180_release_emc_md5_5101524ba86a362ecb8baa240fba1ee9.iso

• When it finishes loading and rebooting (essentially a factory reset), connect via USB keyboard and monitor to it and specify a temporary IP, netmask, and gateway, so that it can communicate on the network--these should be the same as the current network settings for the RPAs.

• Retrieve the previous settings via boxmgmt, which might mean retrieving them from the DR cluster via boxmgmt, under Setup > Get Remote Settings.

• Apply Settings via boxmgmt, at Setup > Apply Settings.

• Select repository volume (in this instance both RPAs will only select, not format), at Setup > Configure Repository Volume > Select An Existing Repository Volume.

• Attach to cluster and automatically reboot, at Attach RPA To Cluster.

• Once the first RPA comes back up online and it can be confirmed that it is actively replicating consistency groups, then repeat the same operation with the second RPA.
