Cisco Systems 57712 manual Configuring the Flexible Flash Controller Properties, Scenario Behavior

Managing the Server

Configuring the Flexible Flash Controller Properties

Following is the behavior of the RAID partition enumeration when there are two cards in the Cisco Flexible Flash controller:

Scenario	Behavior
Single card	RAID partitions are enumerated if the card is healthy,
	and if the mode is either Primary or
	Secondary-active.
Dual paired cards	RAID partitions are enumerated if one of the cards
	is healthy.
	When only one card is healthy, all read/write
	operations occur on this healthy card. You must use
	UCS SCU to synchronize the two RAID partitions.
Dual unpaired cards	If this scenario is detected when the server is
	restarting, then neither one of the RAID partitions is
	enumerated.
	If this scenario is detected when the server is running,
	when a user connects a new SD card, then the cards
	are not managed by the Cisco Flexible Flash
	controller. This does not affect the host enumeration.
	You must pair the cards to manage them. You can
	pair the cards using the Reset Configuration or
	Retain Configuration options.
