Restoring The System Configuration - IBM Storwize V7000 Troubleshooting And Maintenance Manual

The cluster_ip is the IP address or DNS name of the system and
offclusterstorage is the location where you want to store the backup files.
Tip: To maintain controlled access to your configuration data, copy the backup
files to a location that is password-protected.

Restoring the system configuration

Use this procedure in the following situations: only if the recover procedure has
failed or if the data that is stored on the volumes is not required. For directions on
the recover procedure, see "Recover system procedure" on page 71.
Before you begin
This configuration restore procedure is designed to restore information about your
configuration, such as volumes, local Metro Mirror information, local Global Mirror
information, storage pools, and nodes. All the data that you have written to the
volumes is not restored. To restore the data on the volumes, you must restore
application data from any application that uses the volumes on the clustered
system as storage separately. Therefore, you must have a backup of this data before
you follow the configuration recovery process.
About this task
You must regularly back up your configuration data and your application data to
avoid data loss. If a system is lost after a severe failure occurs, both configuration
for the system and application data is lost. You must reinstate the system to the
exact state it was in before the failure, and then recover the application data.
Important: There are two phases during the restore process: prepare and execute.
You must not change the fabric or system between these two phases.
If you do not understand the instructions to run the CLI commands, see the
command-line interface reference information.
To restore your configuration data, follow these steps:
Procedure
1. Verify that all nodes are available as candidate nodes before you run this
recovery procedure. You must remove errors 550 or 578 to put the node in
candidate state. For all nodes that display these errors, perform the following
steps:
a. Point your browser to the service IP address of one of the nodes, for
example, https://node_service_ip_address/service/.
b. Log on to the service assistant.
c. From the Home page, put the node into service state if it is not already in
that state.
d. Select Manage System.
e. Click Remove System Data.
f. Confirm that you want to remove the system data when prompted.
g. Exit service state from the Home page. The 550 or 578 errors are removed,
and the node appears as a candidate node.
h. Remove the system data for the other nodes that display a 550 or a 578
error.
