3900 Goes offline

Hi all,

 

I have a 3900 goes offline after a short while it is online.

 

Here is the story, i was creating a cluster between 3900 and 6900. I actually did. When i sync 6900 to 3900 ,3900 went offline.

 

Since 3900 had a config for serial failover , i thought this might be the reason and disabled serial failover.

 

I've followed the procedure below :

 

Log in to the tmsh utility by typing the following command: tmsh

 

Modify the failover.usetty01 database key to enable by typing the following command: modify sys db failover.usetty01 value enable

 

Note: By default, the failover.usetty01 database setting synchronizes between units in a high-availability pair during a ConfigSync operation.

 

Save the change by typing the following command: save /sys config

 

To restart the sod process, type the following command: restart sys service sod

 

After that the device became after for few seconds. And went offline again.

 

It becomes active then it says :

 

Oct 18 18:42:39 DISF5_1 emerg logger: Re-starting bigd

 

I have this in ltm :

 

Oct 18 18:42:39 DISF5_1 info bigd.start[13298]: Execing bigd: /usr/bin/bigd bigd -S

 

Any ideas why am i facing this offline issue?

 

Regards Sadik

 

  • I have this log under ltm. But i can not understand why the unit fails over.

  • Clustering across different platforms isn't supported by F5. If you can make it work, great. If you can't, F5 isn't going to help out if you raise a case.

     

  • Another key point, the 6900's license is expired. But it is functional. It does not welcome me with the re-activate page. But still its not licensed. So i have synced from an unlicensed device, then the 3900 went offline.

     

  • Interesting updates. I have licensed the 6900. But its license did not include ASM. so i disabled asm on both unit. It worked perfectly. Then i have switched the license back to old one (which includes ASM) no problem at all again. When i enabled asm, BOOM! 3900 went offline. Same problem. I have just disabled the ASM and it came back online, cluster is working fine again.

     

    Note : ASM was enabled at the very beginning and when the device was stand alone.

     

    I will try to get a valid license to 6900 which includes ASM and then re-provision that module and see what happens.
