Each SRP module has two NVS cards (0, 1). The NVS cards in the active SRP module are designated disk0 and disk1. The NVS cards in the redundant SRP module are designated standby-disk0 and standby-disk1. After you install new NVS cards or SRP modules, you must issue the synchronize command to match the file system of the NVS card on the redundant SRP module with the file system of the NVS card on the active SRP module. See Replacing an NVS Card for more information.
