PowerStore: How to reinitialize a PowerStore system to factory state using the svc_factory_reset command

Before you begin

• This is a destructive procedure. All data and all configuration on the system is permanently deleted and cannot be recovered. The system is returned to a factory state (same state that it was when initially acquired).
• This procedure reinitializes the system to the same PowerStoreOS version installed on the PowerStore. Do not attempt to downgrade the PowerStoreOS version.
• For PowerStore X, the process is the same but the vCenter side must be manually cleaned up from all previous PowerStore X configuration before the system can be initialized again (Unregister VASA, remove the vDS, remove the PowerStore Cluster). See PowerStore: How to perform vCenter cleanup if cluster creation failed
• ATTENTION: If the VMware license was acquired from Dell and not VMware, contact technical support before starting the procedure.

Procedure

1. Log in to both nodes over ssh. See PowerStore: How to connect to Service Console over SSH
   
   The node IPs can be retrieved from the PowerStore Manager (UI) under Settings > Networking > Network IPs
   If the management IPs are not available, see PowerStore: SSH and PowerStore Manager access using the Service LAN Ports

2. Before proceeding with reinitializing the appliance, ensure that the appliance is healthy and has no hardware issues.
   After logging in as service user, run the following command and look for errors or faults. If any failure is detected, it must be addressed before proceeding:

3. Both nodes must be placed in service mode before the system can be reinitialized.
   This requires two commands. The first sets the service mode flag on the node, and the second reboots the node into service mode.
   
   On both nodes, run:
   svc_rescue_state set
   svc_node reboot local
    
   If errors are observed, the -f (force) flag may be used.
   The nodes take around 10 to 15 minutes to reboot.

4. Once the nodes have rebooted, login to node A and reinitialize the system.
   You know that the node is in service mode as it displays this warning:
   
   [service@1234567-A user]$ 
   *** WARNING *** This Node is currently in Service Mode *** WARNING *** 

5. In order to start the reinitialization process, run the factory reset command on node A only and follow the command prompt guidance:
   
   svc_factory_reset
   
   If errors are observed, the --force flag may be used.

What to expect:

• All data and all configuration on the system is permanently deleted and cannot be recovered once the svc_factory_reset command is issued and accepted.
• The nodes are rebooted and returned to a blank factory state.
• This process takes around:
  • 1 hour to complete for PowerStore T, more for a downgrade between major versions.
  • 1.5 hours for PowerStore X.
• Do not attempt to do anything before the minimum expected duration times listed above.
• Once the reinitialization is complete, the system may be initialized again as if brand new. For info on how to initialize a PowerStore system, consult the documentation available in the support pages.
