In that case it's useful to have the backup be Heartbeat Backup through the MGMT port, since the Heartbeat function sends out ICMP probes and these are processed by the system kernel, and not the ha_agent process. The reason for HA1 link failure is not limited to physical problems, it can also happen if the ha_agent process is busy and can't process HA1 functions. Split brain conditions can be prevented by configuring an HA1 Backup link and/or enabling Heartbeat Backup. Each HA member will assume the other member is in a non-functional state and take over as the Active (A/P) or Active-Primary (A/A).
Split brain conditions occur when HA members can no longer communicate with each other to exchange HA monitoring information. If the HA1 Link fails and there is no HA1 Backup nor Heartbeat Backup configured, configuration synchronization will fail and a split brain condition will be created. I did a bit of research on it, and it said it does it when one PA see a firewall that the other doesn't? But both are setup exactly the same, thoguhts?

With that out of the way, I wanted to say I recently got a Device RMA'd and the process went amazingly smooth, and I actually was able to completed a HA peer PA-500 in less time then it took my provider to get my a digital key for some software!Įverything seemed to go very well. Synchronized.I want to start off saying I love Palo Alto's, they are AMAZING!
To automate this process, this tutorial includes the check_clocks utility tool to verify whether Linux PTP daemons (ptp4lĪnd phc2sys) have been properly configured and the clocks have been For more information about the adjtimex() system call, see Propagated to the kernel, read this offset value using the adjtimex() To verify the TAI offset set by the pmc command above has been correctly Than 100 ns, the System clock is synchronized. If phc2sys consistently reports offset lower The offset information reported by phc2sys shows the time offset between Phc2sys : CLOCK_REALTIME phc offset - 372582 s0 freq + 246 delay 6649 phc2sys : CLOCK_REALTIME phc offset - 372832 s1 freq - 4 delay 6673 phc2sys : CLOCK_REALTIME phc offset 68 s2 freq + 64 delay 6640 phc2sys : CLOCK_REALTIME phc offset - 20 s2 freq - 3 delay 6687 phc2sys : CLOCK_REALTIME phc offset 47 s2 freq + 58 delay 6619 phc2sys : CLOCK_REALTIME phc offset - 40 s2 freq - 15 delay 6680 By following this tutorial, the reader will be able to
