6.2.5 Saving Configuration (NVRAM) to a Disk
You can back up your controller-dependent configuration information. Use this
function to save configuration information whenever you change your array’s
configuration.
The controller-dependent configuration information is stored in the disk reserved
space of all drives that have been configured into logical drives.
Saving your NVRAM controller configuration to a file provides a backup of the
controller-dependent configuration information such as channel settings, host IDs,
FC protocol, and cache configuration. It does not save LUN mapping information.
The NVRAM configuration file can restore all configuration settings but does not
rebuild logical drives.
Note – A logical drive must exist for the controller to write NVRAM content onto it.
1. Choose “system Functions → Controller maintenance → Save nvram to disks.”
A confirmation dialog is displayed.
2. Choose Yes to confirm.
A prompt confirms that the NVRAM information has been successfully saved.
To restore the configuration, see “Restoring Your Configuration (NVRAM) From
Disk” on page 8-20.
