Disk Management Maintenance > [Software & System Management] Disk Management The Disk Management page lists information about physical and virtual appliance disks. n The progress bar shows what percentage of the polling is complete. n Physical appliances use RAID arrays with encrypted disks. n Disk failure results in a critical alarm. n If a row shows that a disk has failed, click Edit to access the appliance, and follow directions in the local help for replacing the failed disk. n You can view the SMART [Self-Monitoring Analysis and Reporting Technology] data from physical appliance disks. Follow this procedure when replacing a failed disk: 1 Log into your Support portal account, and click Open a Self Service RMA for disk replacement. 2 Complete the wizard, using the serial number of the appliance (not the disk). 3 After you receive the new disk, access Appliance Manager by clicking any Edit icon that belongs to the appliance in question. 4 Follow the instructions in that page’s on-line help.
