• 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 HDM2 online
help.
• For an LSI storage controller, the status of the flash card of the powerfail safeguard module will
become Abnormal.
You can also review log messages from HDM2 to identify supercapacitor exceptions.
For the powerfail safeguard module to take effect, replace the supercapacitor before its lifespan
expires.
The supercapacitor might have a low charge after the powerfail safeguard module is installed or after
the server is powered up. If the system displays that the supercapacitor has low charge, no action is
required. The system will charge the supercapacitor automatically. You can view the status of the
supercapacitor from HDM or the BIOS.
the supercapacitor replacement, verify that cache related settings are enabled for logical
drives. For more information, see HDM2 online help.
Installation guidelines
When you install standard storage controllers, follow these restrictions and guidelines:
• Make sure the standard storage controllers are of the same vendor (PMC or LSI). For
information about the available storage controllers and their vendors, use the component
compatibility lookup tool at
http://www.h3c.com/en/home/qr/default.htm?id=66.
• If the drives are installed only at the server front, install storage controllers to different riser
cards. The controller in a lower-numbered slot is connected to the drive backplane for the
higher-numbered drive carriers and the controller in a higher-numbered slot to the drive
backplane for the lower-numbered drive carriers. For more information about the drive carrier
locations.
• If the drives are installed at both the server front and server rear, install storage controllers to
one riser card. The controller in a lower-numbered slot is connected to the rear drive backplane
and the controller in a higher-numbered slot to the front drive backplane. For information about
slot locations, see "
Rear panel view."
Use Table 26 to identify the supercapacitor available for a storage controller.
