Units
When the MegaRAID Storage Manager software is running, you can monitor the status
of all of the BBUs connected to controllers in the server. If a BBU is operating normally,
the icon looks like this
. If a BBU fails, a red dot appears next to the icon.
To show the properties for a BBU, perform the following steps:
1. On the main menu screen, click the Physical tab to open the physical view.
2. Select the BBU icon in the left panel.
The BBU properties appear in the right panel. The BBU properties include the following:
— The number of times the BBU has been recharged (cycle count).
— The full capacity of the BBU, plus the percentage of its current state of charge,
and the estimated time until it will be depleted.
— The current BBU temperature, voltage, current, and remaining capacity.
— If the battery is charging, the estimated time until it is fully charged.
— The battery state, which says if it is in operational state.
— If battery replacement is required.
— The BBU retention time, which gives the total number of hours the battery can
support the current capacity reserve.
The BBU Properties are displayed, as shown in the following two figures.
