120 XPath OS CLI commands

Enables the IP storage fabric configuration server (iFCS) function in the fabric by making the MP Router the

primary iFCS MP Router.

Synopsis

ifcsenable

Availability

admin

Description

Use this command to enable the iFCS function by selecting this MP Router to be the primary iFCS and

making the remaining IP-aware MP Routers to be secondary. The primary iFCS then performs a two-way

merge of its existing configuration with all of the secondary MP Routers in the fabric and continues to do

so whenever there is a change in any IP storage configuration.

A secondary MP Router automatically becomes the primary if the current primary is removed from the

fabric. When this occurs, the primary selection is based on the second and third least-significant bytes of

the MP Router WWN. The secondary MP Router in the fabric with the larger value of those two bytes

becomes the primary. For example, a secondary with a WWN of 10:00:00:05:1e:15:84:00 becomes

primary over another secondary with a WWN of 10:00:00:05:1e:12:de:00 because 0x1584 is larger

than 0x12de.

The iFCS function distributes the IQN-to-WWN mapping of each iSCSI host and their shared Challenge

Handshake Authentication Protocol (CHAP) secret configuration to all IP storage-aware routers in the

fabric. This distribution enables iSCSI hosts to move from one MP Router to another MP Router within a

fabric.

iFCS is disabled by default.
