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.
- 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
- Remove the license from the cluster.
From RP GUI -->Admin --> Manage Licenses --> select the license and click Remove.
- 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
- 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).
- 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
- Dettach the RPAs from the cluster.
By ssh to the RPA using boxmgmt user.
From Main Menu select: [4] Cluster operations --> [1] Detach RPA from cluster.
- For RP/SE, on the VNX storage array de-register the RPAs initiators.
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).
- Delete the RPA storage group on the storage array.
- If the cluster is a vRPA cluster:
- 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.
- Remove the vRPAs from the ESX.
- Redeploy the vRPAs, please check RecoverPoint vRPA Technical Notes for steps of deploying the vRPAs.
- Use Deployment Manager to re-install the cluster.
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.
