NOTE: Whenever the DR Series system enters or exits from the Maintenance mode state, all communication via CIFS, NFS, OST, or RDS is lost. The set of maintenance commands and options should only be used when the DR Series system is in the Maintenance mode state. Dell recommends that you contact Dell Support before performing any of these DR Series system CLI commands. The --filesystem commands perform maintenance operations on the DR Series system file system, the --configuration commands perform a backup and restore of the system configuration, the --hardware commands manage the appliance hardware, the --disk commands manage the system disk drives, and the --vdisk commands manage the virtual disk drives. NOTE: This set of maintenance commands provide some functionality that is not available in the DR Series system GUI. To check the status of the DR Series system, use the DR Series system CLI system --show command to display the current status. Maintenance Command Usage This topic introduces the maintenance command usage: NOTE: Using some of the maintenance command options could result in the deletion of data.
