Verifying component failure
Look at the system health LED for the controller cards (2, Figure 125 (page 257)) to determine if
there is a problem.

You can also check the Hardware Information tab in the CMC (select Diagnostics for the applicable
storage system and then select the Hardware Information tab). If a RAID controller is not working,
it will not be visible on the Hardware Information tab.
Because there are two RAID controllers in the P4900 G2, it is important to know which one is
being replaced. The RAID controller that manages drives 1–4 and is the OS partition is installed
in the PCIex16 slot of the riser assembly(Figure 126 (page 258)) and is called Card 1. The RAID
controller that manages drives 5–8 is installed in the bottom PCIex8 slot and is called Card 2
(Figure 127 (page 258)). Review the Alarms section of the CMC to determine if any alarms have
been generated for the cache module or battery.
