Big-IP reboot unexpectedly

Hi everyone,

 

 

Our BIG-IP 1600 system rebooted unexpectedly after a "bigstart restart" command was launched by the HA monitor processes.

 

 

The following log can be seen in ltm.log

May 11 04:09:43 local/xxxxxxx info mprov: No mountpoints existed, likely first boot after upgrade.

 

 

We are running 10.2.0 version.

 

 

Any ideas why this happened?,

 

 

Thanks in advance,
