KERN_INSTANCE_NUM

[THG-MID]

Hi

Have a 1575 xlcluster running (a old version) R81.10.07 (996001397).

I had a issue where the cluster would not sync correctly as one device had configured 4 kernel cpu and the other 3 kernel cpu. This, i fixed by setting both devices to 3 cpu with command FW_BOOT_DIR=/opt/fw1/boot fwboot corexl enable 3.

Looking at the boot.conf file (cat /opt/fw1/boot/boot.conf) i see 1 device has KERN_INSTANCE_NUM set to 4 and the other to 3. Without knowing i guess they should be identical.

How do i change KERN_INSTANCE_NUM to 3 in expert mode on a Quantum Spark device?

Regards
Robert

Hi Robert,

It's not healthy to manually change the number of cores,

As I assume you have a cluster of 2 1575, the core discrepancy is probably due to a missing license in one of the appliances.

please check your license status. 

If it still doesn't work please ask to open a CFG Task.

Thanks

Are you sure both appliances are both 1575? They should have 3 cores and not 4

Model of a Quantum Spark Appliance	Total number of CPU cores	Default number of IPv4 instances when IPv6 is disabled	Default number of IPv4 instances when IPv6 is enabled	Default number of IPv6 instances when IPv6 is enabled	Maximum* number of IPv6 instances when IPv6 is enabled
1535	3	3	2	2	2
1530	3	3	2	2	2
1555	4	4	2	2	2
1550	4	4	2	2	2
1575	3	3	2	2	2
1570	3	3	2	2	2
1595	4	4	2	2	2
1590	4	4	2	2	2

Is license also the same? Maybe one has or had trial?

Symptoms

• In 1530 and 1570 appliances, the gateway shows 4 cores when using a trial license. After deploying the license from the User Center, the number of visible cores is 3.

Cause

After license activation, the 1530 and 1570 appliances lock one core.

This also applies to other Gaia Embedded devices.

Solution

No fix is required; the system is functioning as designed.

Can you also check this?

IPv4 CoreXL Firewall instances

To view the current number of IPv4 CoreXl Firewall instances, run:

fw ctl multik stat

To change the number of IPv4 CoreXL Firewall instances:

1. Run this command in the Expert mode:

   FW_BOOT_DIR=/opt/fw1/boot fwboot corexl enable <Number of IPv4 Instances>

2. Reboot the appliance.
