Hot swap allows exchange of faulty disk unit parts without stopping the application in the event of a mirror disk failure. With GDS, administrator does not have to be aware of the system configuration. The system configuration is transparent to the administrator. Therefore, the administrator can simply select a failed disk displayed in the GUI window to conduct preparation before swapping disks and restoration through mirroring after the swapping. If a spare disk has been operating in place of the defective disk unit, the spare disk will disconnect automatically, returning to its original state.
Conditions for Hot Swap
GDS's function for hot swapping is available only when using a disk unit supporting hot swapping.
Do not remove or insert a disk when using a disk unit not supporting hot swapping. It may cause breakdown, or damage data.
