You can use the nlvm rescan command to scan for storage objects (such as partitions, NSS pools, and NSS software RAIDs) on known devices. It creates and updates Device Mapper objects, and mounts pools as needed. Use the -m option if you do not want to automatically mount any unmounted pools. For command usage information, see OES 2015 SP1 Beta: NLVM Reference.
Log in to the server as the root user, then open a terminal console.
Rescan the system for storage objects by entering
nlvm -m rescan
The -m option causes it to not automatically mount any pools on the system.
