Symptoms
SANNav is unable to display the Performance data graph for any of the switches:
Cause
Properties option of the seed switch (Inventory switch properties) displays that "Bound to server" option displays an error as below:Bound to server: xx:x:xxx:xxx (not the current server).The above message indicated that IP displayed in the properties of the switch is not of the current SANnav server.
Resolution
These commands to be ran by root user on the seed switches first:
telemetryapp --show all
(To determine whether a switch is streaming telemetry data to the Brocade SANnav server, SANnav schema has to be registered from the switch to stream perf data.)
mgmtapp --unbind
(Clears the binding of the switch to the Management application to allow a different instance of the Management application to manage the switch. This option also clears the collection configuration created by the application.)
telemetryapp --show all
To check if the old (wrong) registration is removed.Once above action is completed on CLI, proceed with the below action plan:
Log in to SANnav.Go to SANnav > Fabric Discover.Click View option for the concerned fabric which contains the problematic switches.Click the concerned switch and click Stop Monitoring option.Click Monitor option.
NOTE: “telemetryapp --show" command is not indeed supported on GEN 5 switches, but only on GEN 6 and GEN 7 switches so it will not run on 6510 or 6520.
The only reason why we are using it, is to check the telemetry registration, so we will not be able to check the telemetry registration on GEN 5 switches.You can go ahead and unbind the current registration and follow the remaining of the steps of the actions.To resolve the issue for the switch which are running on FOS 9.1.x or above follow the below prcoedure : 1) login to admin account and enable maintenance account in next two steps (which is disabled by default)
admin > userconfig --show maintenance
admin > userconfig --change maintenance -e yes
2) login in to maintenance accountenter default password which is 'password'you will then automatically be prompted to change the default password 3)Check the telemetry status on the switch.
maintenance> fosdbg_telemetry --show all
4) Unbind the telemetry app:
mgmtapp --unbind
Application unbind success
5) Validate no telemetry schema
fosdbg_telemetry --show all
Found no entries
6) Reconnect the telemetry schemaGo to SANnav - Fabric DiscoverySelect the fabric which holds the switch with the Telemetry errors and use the drop down button on the right of the fabric and select Stop Monitoring.When the fabric status is unmonitored then again use the drop down button on the right of the fabric and select Start Monitoring. 7) Validate the server state is connected and enabled on the switch.
fosdbg_telemetry --show all
IP of the SANnav server listed properly and performance graph was displayed correctly.
