Instructions

Steps for uninstalling the cluster from RecoverPoint system:

Before reinstalling the cluster, you can save the settings of the current consistency groups to import them after reinstalling.
To save the settings: ssh to the site control RPA using admin user and run command "save_settings" then copy the output to a file.
  1. Remove the copies at the cluster being uninstalled from every consistency group.
     If the cluster has a source copy for a CG , you will need to remove the whole CG
From RP GUI --> Protection --> Manage Protection --> select the CG from the left tab and click Remove Group
     If the cluster has replica copies , you will only need to remove this copy from the CG
From RP GUI --> Protection --> Manage Protection --> select CG from the left tab and select the copy and click Remove Copy
  1. Remove the license from the cluster.
From RP GUI -->Admin --> Manage Licenses --> select the license and click Remove.
  1. Dettach the splitters from the cluster.
From RP GUI --> RPA Clusters --> Cluster Name tab --> Splitters --> select the splitter in the splitter table and click Remove
  1. Clear the cluster settings.
Run ssh to the RPA using admin user and run command "clear_settings"

Note: If you are having 3 clusters or more and replication is ongoing on the two healthy clusters , running command "clear_settings" will clear the settings on all the clusters (the cluster needed for re-install and the healthy clusters).
  1. Remove the cluster from the system.
Run ssh to the site, control RPA of the other cluster using boxmgmt user.
From Main Menu select: [4] Cluster operations --> [3] Remove a cluster from this system
  1. Dettach the RPAs from the cluster.
By ssh to the RPA using boxmgmt user.

From VNX unisphere --> Hosts --> Initiators --> then enter Engineering mode and select the initiator and deregister it  
(Please engage VNX support to assist in entering the Engineering Mode).
  1. Delete the RPA storage group on the storage array.
  2. If the cluster is a vRPA cluster:
    1. Delete the iSCSI paths on the storage:
1] In VNX for Block Command Line Interface, obtain a list of the iSCSI path sets to be removed by using the following command:
naviseccli -h -user -password -scope 0 connection  getset
2] Delete the iSCSI path sets obtained in the previous step. Use the following command for each path set to remove:
naviseccli -h -user -password -scope 0 connection - delset  name -o

Make sure that you remove only the path sets of the cluster to be uninstalled.
  1. Remove the vRPAs from the ESX.
  2. Redeploy the vRPAs, please check RecoverPoint vRPA Technical Notes for steps of deploying the vRPAs.
  1. Use Deployment Manager to re-install the cluster.

Additional Information

When reinstalling RP/CL or EX, will need to register the initiators, recreate the RP storage group and bind the LUNs and hosts manually.

If you are reinstalling the cluster to a higher version need to convert the save_settings file to the higher version before applying it.
