Nexux 5596-UP "show hardware internal" command problem

Hi all,

I have a problem with one of our Nexus 5596. When I execute the following command on module 1 for any fc port, the switch displays an error:

show hardware internal fc-mac 1 port <fc_port_ID> port-event

**************************************************************************************************************************

switch-n5k-2# sh hardware internal fc-mac 1 port 43 port-event

gat_fcp_cli_port_port_event: dev_debug() returned error, errno = 22, rc = -1

switch-n5k-2# sh hardware internal fc-mac 1 port 44 link-event

gat_fcp_cli_port_link_event: dev_debug() returned error, errno = 22, rc = -1

******************************************************************************************************

The NX-OS version is: 5.1(3)N2(1b) and ports conecct to MDS-9000 and Servers.

Has someone else this problem?

Thanks in advance!

Nexux 5596-UP "show hardware internal" command problem

Hello Iker,

Yes you are right the 96 have 48 fixed ports.

But in my 5548 it is 32 and i have the same error if i make the show command on a non exsiting port.

as shown up in my first reply.

If you have 7 identical N5596UP and you do not have the problem on others i would investergaate that.

Do you run the same NX-OS on them and are tey configured right?

If that is the case i would open a case with TAC I would also check that the NX-OS you are running has not been revoked.

My setup is a testlab so not en real production by my carmelusd task takes less than 1 % and the highes take about 6% CPU

sh processes cpu sort | include carme

3147     86117625  116934966    736    0.9%  carmelusd

Best regards,

Nexux 5596-UP "show hardware internal" command problem

Hello Iker,

I have only the same problem if I issue the same command on a non existing port.

Remember how the 5596 is build you have 32 ports in slot 1 and then slot 2, 3 and 4. with each 16 ports

So it is only a cosmetic bug that you can issue it and if you list your interface with a show interface brief you can see it.

running code 5.2(1)N1(4)

Nexux 5596-UP "show hardware internal" command problem

Hello Chald,

first of all, thank you for your interest and your response, but you are wrong. The Nexus 5596-UP have 48 ports in module 1, and 3 expansion slots for modules 2, 3 and 4.

The problem we have is that fc1/4x ports exist, and the error occurs with all the ports in module 1.

Moreover, we have 7 Nexus 5596 more in our enviroment, wit same configuration, and don't have these events.

Could it be a bug? Maybe, but I'm worried because "carmel" process has a consumption about 50% of the CPU.

Any idea is appreciated.

Thank you very much!

Regards.

Hello Chald,

thank you very much for all.

Finally, we'll have to open  a TAC case.

Nexux 5596-UP "show hardware internal" command problem

After opening a case with the Cisco TAC, they said us that we were affected by the following bug : CSCu27720.

https://tools.cisco.com/bugsearch/bug/CSCuj27720

The workaround to solve the problem was to reload the Nexus 5596UP switch.
