Replacing a storage controller and a power fail
safeguard module
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before
touching them.
For some storage controllers, you can order a power fail safeguard module to prevent data loss
when power outage occurs.
A power fail safeguard module provides a flash card and a supercapacitor. When a system power
failure occurs, this supercapacitor can provide power for a minimum of 20 seconds. During this
interval, the storage controller transfers data from DDR memory to the flash card, where the data
remains indefinitely or until the controller retrieves the data.
A supercapacitor has a lifespan of 3 to 5 years. If the lifespan of a supercapacitor expires, a
supercapacitor exception might occur. The system notifies users of supercapacitor exceptions by
using the following methods:
•
For a PMC storage controller, the status of the flash card will become
Abnormal_status code
.
You can check the status code to identify the exception. For more information, see HDM online
help.
•
For an LSI storage controller, the status of the flash card of the power fail safeguard module will
become
Abnormal
.
You can also review log messages from HDM to identify supercapacitor exceptions.
