QLogic Distributed Subnet Administration
ScanFrequency
Periodically, the Distributed SA will completely re synchronize its database. This
also occurs if the Fabric Manager is restarted. ScanFrequency defines the
minimum number of seconds between complete re synchronizations. It defaults to
600 seconds, or 10 minutes. On very large fabrics, increasing this value can help
reduce the total amount of SM traffic. For example, to set the interval to 15
minutes, add this line to the bottom of the qlogic_sa.conf file:
ScanFrequency=900
LogFile
Normally, the Distributed SA logs special events to /var/log/messages. This
parameter allows you to specify a different destination for the log messages. For
example, to direct Distributed SA messages to their own log, add this line to the
bottom of the qlogic_sa.conf file:
LogFile=/var/log/SAReplica.log
Dbg
This parameter controls how much logging the Distributed SA will do. It can be set
to a number between one and seven, where one indicates no logging and seven
includes informational and debugging messages. To change the Dbg setting for
Distributed SA, find the line in qlogic_sa.conf that reads Dbg=5 and change it to a
different value, between 1 and 7. The value of Dbg changes the amount of logging
that the Distributed SA generates as follows:
• Dbg=1 or Dbg=2: Alerts and Critical Errors
Only errors that will cause the Distributed SA to terminate will be
reported.
• Dbg=3: Errors
Errors will be reported, but nothing else. (Includes Dbg=1 and Dbg=2)
• Dbg=4: Warnings
Errors and warnings will be reported. (Includes Dbg=3)
• Dbg=5: Normal
Some normal events will be reported along with errors and warnings.
(Includes Dbg=4)
• Dbg=6: Informational Messages
In addition to the normal logging, Distributed SA will report detailed
information about its status and operation. Generally, this will produce
too much information for normal use. (Includes Dbg=5)
