Monitoring Controllers and Their Attached Devices : Monitoring SuperCap

Monitoring SuperCap

When the MegaRAID Storage Manager software is running, you can monitor the status of all of the SuperCaps connected to controllers in the server. If a SuperCap is operating normally, the icon looks like this: . If a SuperCap fails, a red dot appears next to the icon.

CAUTION  Do not hot plug the SuperCap when power is supplied to the controller card or if there is residual charge on the SuperCap, doing so might damage both the SuperCap and the controller card.

To show the properties for a SuperCap, perform the following steps:

1.

On the main menu screen, click the Physical tab to open the physical view.

2.

Select the SuperCap icon in the left panel.

The SuperCap properties appear in the right panel. The SuperCap properties include the following:

*

The number of times the SuperCap has been recharged (cycle count).

*

The full capacity of the SuperCap, plus the percentage of its current state of charge, and the estimated time until it is depleted.

*

The current SuperCap temperature, voltage, current, and remaining capacity.

*

If the SuperCap is charging, the estimated time until it is fully charged.

*

The SuperCap state, which says if it is in operational state.

*

If SuperCap replacement is required.

*

The SuperCap retention time, which gives the total number of hours the SuperCap can support the current capacity reserve.
