Hi,
As one of the FC cards connected to hpux server is having some domain change issue, i need to deactivate the FC card.

How to find the defective FC card and how to disable the FC card.
I am new to working with FC card.

Please help me.

What is the issue?

>>"How to find the defective FC card?"

You need to tell the server model and the hardware path of the card.

You deactivate it with fcmsutil, see

man fcmsutil

[Grayh]

from the following command u may find the defective FC card:-

#echo "map selall info;wait infolog" | cstm
#ioscan -fnCfc
# fcmsutil /dev/fcd0

And then replace the FC card if found defective.

Thanks both of you!!

The actual issue is the domain id of one of the switch is changed somehow. so the device paths and device IDs are changed in the hpunix servers which are connected to that switch.

so to fix this issue, storage team wants us to deactivate the defective fc card.


please let me know if any additional inputs.

thanks!!

So you will see a lot of NO_HW entries in "ioscan" and probably new devices without a device file.

I wonder what the deactivation should bring ...

Hi Torsten,
Normally the setup of hpunix here is having two fc cards. Currently they want the hpunix servers to run in only one working HBA card. so that the other FC card is disabled and whatever changes they are doing on the cisco switch will not affect the servers.

You will find the card associated with all the NO_HW entries in ioscan.

You can use

fcmsutil disable

see
http://docs.hp.com/en/B3921-60631/fcmsutil.1M.html

or just pull the cable.
