Replacing a RAID disk
When replacing a disk in the RAID array, the new disk must have the same or greater storage capacity than the existing disks in the array. If the new disk has a larger capacity than the other disks in the array, only the amount equal to the smallest hard disk will be used. For example, if the RAID has 400 GB disks, and you replace one with a 500 GB disk, to be consistent with the other disks, only 400 GB of the new disk will be used.
FortiRecorder units support hot swap; shutting down the unit during hard disk replacement is not required.
To replace a disk in the array
1. Go to System > Storage > Local Storage.
2. In the row corresponding to the hard disk that you want to replace (for example, p4), select the hard disk and click Delete.
The RAID controller removes the hard disk from the list.
3. Protect the FortiRecorder unit from static electricity by using measures such as applying an antistatic wrist strap.
4. Physically remove the hard disk that corresponds to the one you removed in the web UI from its drive bay.
5. Replace the hard disk with a new hard disk, inserting it into its drive bay.
6. Click Refresh.
The RAID controller will scan for available hard disks and should locate the new hard disk. Depending on the RAID level, the FortiRecorder unit may either automatically add the new hard disk to the RAID unit or allocate it as a spare that will be automatically added to the array if one of the hard disks in the array fails.
The FortiRecorder unit rebuilds the RAID array with the new hard disk. Time required varies by the size of the array.
