360 Systems TSS-2470 II Operation Manual page 43

Drive Replacement
If the array continues to indicate a failed drive, replace the drive. Although the drives are hot
swappable and can be replaced while the system is running, it is recommended that if possible
the unit be taken offline and powered off prior to conducting any maintenance or repairs.
If the drive is hot swapped, the system should recognize within no more than 5 minutes that a
new drive has been installed, and start to rebuild the array.
If the rebuild process does not start automatically, it may be necessary to cycle power. If this
does not result in the rebuild starting automatically, contact 360 Systems support.
When powering up with a newly replaced drive, the RAID boot up screen should indicate that the
drive is present. Once the system has powered up the rebuild operation should start and be
indicated in the status line. The system can be used immediately, but if possible allow the RAID
to finish rebuilding before putting the system back in service. If the Recording process starts
automatically, simply click the Stop button in the GUI.
A hard disk array ideally should be repaired using the same drive model and capacity as other
drives in the array. Because specific drive models become unavailable as time goes on, 360
Systems recommends that maintenance spares be purchased at the same time as the server. It is
possible to use a larger drive than the original; in this case the drive will be partitioned to match
the size of the original.
When ordering spare drives, note carefully which model TSS-2470 Time Delay you have as the
drives may vary depending on the model.
The server hard disk drives have been factory tested and configured in a RAID 5 array. Each
drive is numbered (0-3) and must be attached to the correctly numbered data cable. Drive
bays are also numbered.
