save-config

Allows you to save the group configuration to a file and use the information to restore a group in the event of a complete group failure.

Note: The save-config command does not restore volume data.

To restore a group, you must have the same number of members as existed in the group prior to the failure; otherwise, you must edit the save-config file to customize the new group configuration.

The save-config command generates a restoration file, by default named config.cli, which contains the CLI commands needed to recreate the group and saves the file on an array. Use ftp or scp to copy the file from the array to a host for safe-keeping (as described in diag). However, on the ftp open command line, be sure to specify the group IP address.

The save-config command can be run in default or group-only mode. In default mode, the resulting file will automatically restore the following:

• Replication partner configuration
• Storage pools
• Member RAID level, pool, and network interface configuration
• Group customization, including lists of servers
• Volume configuration, including access control records
• Volume collection configuration
• Schedules for snapshots and replication
• Local CHAP account configuration
• Event settings
• Account configuration

If you specify the save-config command with the -grouponly parameter, member and pool configuration information will be saved as comments instead of commands, so you must manually restore these parts of the configuration. A member’s RAID level and pool must be configured before you can use the storage.

The save-config -grouponly command will not restore the basic member network configuration or the group configuration, but it will save this information as comments in the restoration file. The following information must be manually supplied to each member by running the setup utility:

• Group name and IP address
• Passwords
• Member name, IP address, default gateway, and netmask.

Note: A save-config file may not be able to successfully restore a member that is running a firmware version that is different from the firmware that was running on the array that generated the restoration file.

Format

saveconfig [-verbose] [-grouponly] [file_name]

Parameter

Variable 

Examples

The following command saves the group configuration to a specified file name:

> save-config group23rest.cli

configuration saved to group23rest.cli

You can retrieve the file using ftp or scp.

The following command saves the group configuration to the default file name with member and pool information commented out:

> save-config -grouponly

configuration saved to config.cli

You can retrieve the file using ftp or scp.

To restore a group, follow these steps:

1. Run the reset command on each member. Contact your array support provider before running the reset command.
2. Run setup on each member and specify the member configuration (member name, IP address, netmask, and default gateway) and the group configuration (group name, IP address, and passwords).
3. If you used the group-only option, set up the pools, then for each member, select the pool and RAID level, and configure the network interfaces.
4. Use ftp or scp to copy the saved restoration file to an array, as described in update. However, on the ftp open command line, be sure to specify the group IP address.
5. Use telnet or SSH to connect to the group IP address and log in to the group. At the CLI prompt, use the following format to execute the commands in the restoration file:

exec -echo -ignore ../mgtdb/update/file_name

For example:

> exec -echo -ignore ../mgtdb/update/group23rest.cli
