NSX-T manager error_code 101?

niceguy001 — Mon, 08 Apr 2019 03:27:27 GMT

i deployed a nsx-t 2.4 manager on KVM with "medium" type, it worked just fine until i installed second manager(on another KVM host) and join it to the first one.

they all display the following messages on the web browser after i type in the admin account and password to login, as shown below:

i could not figure out why this error happen and it just can't be fixed after i restart services such as "ui-service" in the manager or even reboot the manager.

does anyone know why? the "manager.log" and "syslog" in the manager appliance did not show messages which is truly helpful.

Are you able to reach from Manager1 to Manager 2 ?

Can you check the logs on Primary Manager

hi abhishekkunal5125,

the first manager is able to ping the second one and the second manager can also ping to the first one.

in the primary manager, I used the command "get log-file" to retrieve messages,

the messages in syslog is shown below:

the messages in manager.log is shown below:

napi.root.cluster.cbm_response WARNING Connection to cbm refused or timed out: 111

and the messages in auth.log is shown below, approximately:

i guess these information only help a little bit on troubleshooting this error-code-101 issue ?

I had this issue when one of my techs deployed multiple managers at the same time without waiting for them to come up and join the cluster one at a time. Not sure if this would work for you but we ended up powering them all down, then powering them up in sequence with plenty of time in between. After about 60 minutes they appeared to sync up and the error code went away. Granted this is on older, slower hardware.

shazbot1 thanks for the suggestioin!

however, shut down and boot again didn't work for my manager so I chose to gave up on this issue and pretend it as an unknown bug.

I know this is old, but since this was one of the few messages that came up when I did a web search for this error, I wanted to add the solution in my environment when I got this error.

It turns out through a bizarre sequence of events, I had lost all my DNS servers. Once I got that issue fixed and rebooted my NSX Manager, it came back up fine. This was a lab environment, so I only had one NSX Manager Node.

NSX Manager provides a graphical user interface (GUI) and REST APIs for creating, configuring, and monitoring NSX-T Data Center components such as logical switches, logical routers, and firewalls.NSX Manager provides a system view and is the management component of the NSX-T Data Center. For high availability, the NSX-T Data Center supports a management cluster of three NSX Managers.
does anyone know why? the "manager.log" and "syslog" in the manager appliance did not show messages which is truly helpful.
