luci Field cluster.conf Attribute Description
Name name A name for the IBM BladeCenter SNMP device connected to the cluster.
IP Address or Hostname ipaddr The IP address or host name assigned to the device.
UDP/TCP Port (optional) udpport UDP/TCP port to use for connections with the device; the default value is 161.
Login login The login name used to access the device.
Password passwd The password used to authenticate the connection to the device.
Password Script (optional) passwd_script The script that supplies a password for access to the fence device. Using this supersedes the Password parameter.
SNMP Version snmp_version The SNMP version to use (1, 2c, 3); the default value is 1.
SNMP Community community The SNMP community string.
SNMP Security Level snmp_sec_level The SNMP security level (noAuthNoPriv, authNoPriv, authPriv).

SNMP Privacy Protocol snmp_priv_prot The SNMP privacy protocol (DES, AES).
SNMP privacy protocol password snmp_priv_passwd The SNMP Privacy Protocol Password.
SNMP Privacy Protocol Script snmp_priv_passwd_script The script that supplies a password for SNMP privacy protocol. Using this supersedes the SNMP privacy protocol password parameter.
Power Wait (seconds) power_wait Number of seconds to wait after issuing a power off or power on command.
Power Timeout (seconds) power_timeout Number of seconds to continue testing for a status change after issuing a power off or power on command. The default value is 20.
Shell Timeout (seconds) shell_timeout Number of seconds to wait for a command prompt after issuing a command. The default value is 3.
Login Timeout (seconds) login_timeout Number of seconds to wait for a command prompt after login. The default value is 5.
Times to Retry Power On Operation retry_on Number of attempts to retry a power on operation. The default value is 1.
Port (Outlet) Number port Physical plug number or name of virtual machine.
Delay (optional) delay The number of seconds to wait before fencing is started. The default value is 0.

The following command creates a fence device instance for an IBM BladeCenter SNMP device:
ccs -f cluster.conf --addfencedev bladesnmp1 agent=fence_ibmblade community=private ipaddr=192.168.0.1 login=root \
 passwd=password123 snmp_priv_passwd=snmpasswd123 power_wait=60
The following is the cluster.conf entry for the fence_ibmblade device:

 <fencedevices>
  <fencedevice agent="fence_ibmblade" community="private" ipaddr="192.168.0.1" login="root" name="bladesnmp1" \
   passwd="password123" power_wait="60" snmp_priv_passwd="snmpasswd123" udpport="161"/>
 </fencedevices>
