Emergency Hotspare
When a drive within a redundant virtual drive fails or is removed, the MegaRAID firmware
automatically rebuilds the redundancy of the virtual drive by providing an emergency hotspare
(EHSP) drive; even if no commissionable dedicated or global hotspare drive is present.
Emergency Hotspare for Physical Drives
The Emergency Hotspare property determines whether a particular drive is capable of becoming
an emergency hotspare. This property is displayed under the controller properties, only if the
Global Hotspare for Emergency and the Unconfigured Good for Emergency controller properties
are enabled.
Follow these steps to view the Emergency Hotspare property:
1. In the Logical view or Physical view, click the drive for which you want to view hotspare
properties.
The emergency hotspare property is displayed under general properties, as shown in the
following figure. This property denotes whether a particular drive is capable of becoming a
Hotspare.
