Re: Firmware upgrade from 6.3.0 to 6.4.0

Upgrade to 6.4.1 if you have access to the firmware, has some good features.

Documentation is available on the horizontal bar above OR by clicking the link below. But this is probably a restricted to customers and partners.

You may find the guide on your OEM website - for ex HP ITRC or Powerlink

Re: Firmware upgrade from 6.3.0 to 6.4.0

It should be fine - you may however read the release notes for the FOS release and check compatibility etc. I have upgraded very recently from 6.3.0b to 6.4.1 without any problems.

Firmware upgrades and downgrades


Upgrading to Fabric OS 6.4.0b is allowed only from Fabric OS 6.3.x. The policy to support one-level migration only, which began with Fabric OS 6.0.0, provides more reliable and robust migrations. By having fewer major changes in internal databases, configurations, and subsystems, the system can perform the upgrade more efficiently, ensuring a truly seamless and nondisruptive process for the fabric. The one-release migration policy also reduces the number of upgrade-downgrade permutations that must be tested, allowing for thorough testing and verification of supported migration paths.

If you are migrating from Fabric OS 6.1.x, HP recommends that you use Fabric OS 6.2.2c as the migration path to 6.3.x, and on to 6.4.0a in order to reduce the risk of exposure to known issues at earlier 6.2.x levels.

Re: Firmware upgrade from 6.3.0 to 6.4.0

Thanks for quick response ..

I have one more query ...i have gone through the FOS release of v6.4.0 and i found the following comments like :

If Bottleneck detection feature is currently enabled on the switch running FOS v6.3.x, you must disable it before upgrading to FOS v6.4.0; otherwise, frame drops may occur due to increased Hot Code Load (HCL) time.

As i have a new switch that is not in production and no devices are attached though .

So as per my understanding Bottleneck detection feature must be disabled initially .

I have also tried following command and the output was none

CSFSW11:FID128:admin> bottleneckmon --status
CSFSW11:FID128:admin>


Any suggestions would be appreciated ...Thanks!!!

Re: Firmware upgrade from 6.3.0 to 6.4.0

Since your switch is not in production its no problem, and it does not look like bottleneckmon is enabled on your switch anyways.

Happy upgrade
