Replacing the SAS drive controller card
The serial-attached SCSI (SAS) drive controller card attaches to the riser card assembly and coordinates communication
between the node hard drives. Replace a failed SAS card as soon as possible to reduce node downtime.
Prerequisite: Before replacing the SAS drive controller card, you must remove the PCI Express riser card assembly.
