HP StorageWorks XPath OS 7.4.X Administrator Guide (AA-RVHDD-TE, February 2006)

58 Using the FC-FC Routing Service
Monitoring resources
It is possible to exhaust resources, such as proxy PIDs. Whenever a resource is exhausted, the MP Router
generates an error message. Messages are described in the HP StorageWorks XPath OS 7.4.x system error
messages reference guide.
You can monitor MP Router resources with the fcrResourceShow command:
See the HP StorageWorks XPath OS 7.4.x command reference guide for details about the command.
Routing ECHO
The MP Router and Fibre Channel Routing let you route the ECHO generated when an fcPing command
is issued on a Fabric OS-based switch, providing fcPing capability between two devices in different
fabrics across the MP Router.
NOTE: Each MP Router in a backbone fabric routing to McDATA fabrics must have XPath OS 7.4.x or
later installed. Fabrics that consist entirely of HP devices work with MP Routers using XPath OS 7.1.2, 7.3.x,
or 7.4.x.
Checking for Fibre Channel connectivity problems
1. On the Fabric OS switch, issue the fcPing command, which:
• Checks the zoning configuration for the two ports specified
• Generates an Extended Link Service (ELS) frame ECHO request to the source port specified and
validates the response
• Generates an ELS ECHO request to the destination port specified and validates the response
Regardless of the device’s zoning, the fcPing command sends the ELS frame to the destination port. A
device can take any one of the following actions:
• Send an ELS Accept to the ELS request.
• Send an ELS Reject to the ELS request.
• Ignore the ELS request.
