Rule for LSAN device counts
In the following example, when the total device count in all switches that are part of the metaSAN
(edge plus Backbone) fabric rises above 90 percent of the total permissible count in the fabric, MAPS
reports the threshold violation using a RASLog message on that platform.
switch0:FID128:admin> mapsrule --create LSan_Dev_Count -group SWITCH -monitor
LSAN_DEVCNT_PER -timebase none -op ge -value 90 -action RASLOG -policy
scalability_policy
Rule for Fibre Channel router count in Backbone fabric
In the following example, when the maximum limit of 12 Fibre Channel routers in the Backbone fabric
is reached, MAPS reports the threshold violation using a RASLog message.
switch:admin> mapsrule --create FCRCount -group SWITCH -monitor BB_FCR_CNT -t none -
op ge -value 12 -action RASLOG -policy scalability_policy
Rule for zone configuration size
In the following example, when the zone configuration size limit reaches 90 percent of the total size,
MAPS reports the threshold violation using a RASLog message.
switch:admin> mapsrule --create ZoneConfigSize -group SWITCH -monitor ZONE_CFGSZ_PER
-timebase none -op ge -value 90 -action RASLOG -policy scalability_policy
MAPS Service Availability Module
The MAPS Service Availability Module (MAPSSAM) reports display CPU, RAM, and flash memory
usage, and the port status for every physical and virtual Fibre Channel port on the switch.
There are three MAPSSAM commands: mapsSam --show, mapsSam --clear, and mapsSam --help.
Only mapsSam --show has additional parameters. These parameters are listed in the following table
and illustrated in the following examples.
MAPSSAM command options TABLE 20
Option Details
--show (default
option) For each physical and virtual Fibre Channel port on a switch, this displays the total up,
down, and offline time (as percentages), and the number of times the port has been down.
This enables you to see if a particular port is failing more often than the others.
NOTE
The report does not distinguish why a port is recorded as down, it only reports how long the
port has been down.
--show cpu
Displays the CPU usage as a percentage.
--show memory
Displays the general RAM memory usage as a percentage, along with total, used, and free
memory values.
--show flash
Displays the flash memory usage as a percentage.
The following examples show the from using the various mapsSam --show parameters.
