How can i configure fence_cisco_ucs with redhat cluster suite.

i was trying to configure fencing aganet with red ahat cluster suite

i issued command

#  /usr/sbin/fence_vmware_soap -a -l admin -p duc2Cisco -o reboot

then i got below error:

Failed: You have to enter plug number

Please use '-h' for usage

what is this plug number and from where can i get this plug number.?

I am new to this Cisco UCS, becuase this hardware is provided my some other team and i am the one installing Red Hat cluster suite. I requested fencing agent configuration with Cisco, and that guy dosen't know what is fencing..

please help me, because of this issue, production got delayed

Hi Ben,

Are you using fence_cisco_ucs or fence_vmware_soap?  For fence_cisco_ucs I believe the plug number is the name of the service profile attached to the server.

thanks for your replay

actually i tried both fence_cisco_ucs and fence_vmware_soap. which one is used for fencing configuration..

i think both method asking for plug number.

i have access to UCS control panel. from where can i get these service or plug number.

i tried te below, i don't i took one profile name from UCS cpanel and checked:

/usr/sbin/fence_cisco_ucs -a -l admin -p duc2Cisco -n org-root/ls-cgceccprd1 -o reboot

Traceback (most recent call last):

  File "/usr/sbin/fence_cisco_ucs", line 147, in


  File "/usr/sbin/fence_cisco_ucs", line 120, in main

    res = send_command(options, "")

  File "/usr/sbin/fence_cisco_ucs", line 92, in send_command


pycurl.error: (28, 'connect() timed out!')

that also got error

Thanks & regards,

Hi Ben,

Which IPs have you tried?  I think it is the ucs manager ip that you need to use.  Are the ports open between the rhel blade and ucsm?  80/443 tcp depending on your setup.

Hi Ben,

Could try adding ssl and removing the org name like this, sounds like a connectivity issue

fence_cisco_ucs -a -l admin -p duc2Cisco -z -n cgceccprd1 -o reboot
