SolutionSometimes, the new installed disk is not properly detect by the system.To fix it:1) Reboot the system.2) Reseat (slot-out/slot-in) the physical disk again to trigger the detection and the rebuild.3) Run CLI execute raid add-disk <disk no.> to add the disk manually.Example disk 0 is the disk number that being replaced.
FAZ # execute raid add-disk 0Added disk 0 to RAID.
4) Run # diagnose sys raid status to check whether the rebuilding is started.Example disk 0 will start the rebuilding, run the same command over time to check the status and disk 0 will be visible as 'OK' if the rebuild is completed.
