4 TROUBLESHOOTING
4.1 METHODS & TOOLS FOR TROUBLESHOOTING AND DATA GATHERING
TROUBLESHOOTING ROUTERS
As you begin sharing devices, display the FC router resources available with fcrresourceshow
NDA-T01-7500:admin> fcrresourceshow
Daemon Limits:
Max Allowed Currently Used
----------------------------------
LSAN Zones: 3000 2
LSAN Devices: 10000 4
Proxy Device Slots: 10000 2
WWN Pool Size Allocated
----------------------------------
Phantom Node WWN: 8192 444
Phantom Port WWN: 32768 894
Port Limits:
Max proxy devices: 2000
Max NR_Ports: 1000
Currently Used (column 1: proxy, column 2: NR_Ports):
4 | 2 1
5 | 2 1
6 | 2 1
It is important to note that, when troubleshooting routed SANs, some commands relate specifically to
switches, and others relate specifically to routers. Switch centric commands would include all the normal
FOS commands, some of which have been updated to include pertinent edge fabric information. The
fabricshow command, for instance, displays all front and translate domains in the edge fabric. Router
centric commands, for the most part, start with “fcr”, like fcrresourceshow, and display information
specific to the routers, and the backbone fabric.
In the fcrresourceshow command output, you can see the per-backbone and per-port maximums for the
following FC Routing resources:
• LSAN zones
• LSAN devices (proxy or physical devices)
• Proxy device slots (device-to-AL_PA mappings)
• Phantom node WWNs
• Phantom port WWNs (includes ports connecting front and translate domains (virtual ISLs),
translate domain ports for proxy devices, and EX_Port(s)
• NR_Ports (stored at every physical port for routing decision purposes)
The scalability limits always override the maximum values in this command output.
