Control processor (CP) card summary

This section provides instructions for replacing a CP card (also known as CP4).

The 4/256 SAN Director CP card integrates the following characteristics:

• Two CP cards: one located in slot 5 and the other in slot 6.

• The configuration on the active CP card is mirrored to the standby CP card; this section includes

steps to ensure that the new CP card boots up as the standby CP card.

• The new CP card assumes the IP address and host name assigned to the slot.

• If the new CP card does not have the same firmware as the active CP card, it must be upgraded

or downgraded to the same firmware version.

• The logical switches in the SAN Director can continue to operate while a CP card is replaced if

the other CP card continues to operate and no failover occurs.
