The appliances are configured with different amount of Firewall cores. On one the amount is 10, and on the other it is 12. ClusterXL requires the same amount of FWKs to be configured on each member.

Run cpconfig and change that under CoreXL

There isn't a cpconfig. It is a Gaia Embedded

[Expert@FW3]# FW_BOOT_DIR=/opt/fw1/boot fwboot corexl enable 10
stat :: No such file or directory

[Expert@FW3]# fw6 ctl multik stat
Unable to open '/dev/fw6v0': No such file or directory
Failed to get multiple kernel statistics: No such file or directory

Maybe be that these commands no longer function on this version?

They do work on my 1530 - but fw6 multik stat only works if IPv6 is enabled. I also saw the stat :: No such file or directory error, but that was caused by a typo - /fw/...

Copy & Paste from sk:

[Expert@fifteenfifty]# FW_BOOT_DIR=/opt/fw1/boot fwboot corexl enable 4

[Expert@fifteenfifty]# 

Maybe because i did try FW_BOOT_DIR=/opt/fw1/boot before in the first tests  - but leaving it out in the command above does not work.

Fun part: Click Tab after

# fwboot corexl

Do you see the same problem with R80.20.35?

I would suggest to ask TAC to resolve this !

Solution:

 create the file manually - 

# cat /opt/fw1/boot/boot.conf
KERN_INSTANCE_NUM 10
COREXL_INSTALLED 1
KERN6_INSTANCE_NUM 2

I did fear such a solution 😒 It has worked for ma because boot.conf did exist already:

KERN_INSTANCE_NUM 4
COREXL_INSTALLED 1
KERN6_INSTANCE_NUM 2

Seems KERN6 is only used if IPv6 is active - but as my 1550 has 4 cores only,  IPv6 on will reduce IPv4 to 2 Cores. You have enabled IPv6 ? Otherwise i would change KERN_INSTANCE_NUM to 12...

I was suggested by the TAC (in my scenario)

I understand that, but if IPv6 is disabled, you would have two unused cores. Or does fw ctl multik stat show all 12 Cores as active?

in this sk174423 (Configuring CoreXL Firewall instances on Quantum Spark Appliance)

there is a table that explains this

No, same core can serve as IPv4 and v6 at the same time. It is not just one or another. With 12 cores, you need at least 2 of them for SND/PPK, hence 10 CoreXL cores recommendation for a standard config.

Yes, that is the answer -SND/PPK of course need 2 cores !
