6.6. Listing Fence Devices and Fence Device Options
You can use the
ccscommand to print a list of available fence devices and to print a list of options for each available fence type. You can also use the
ccscommand to print a list of fence devices currently configured for your cluster.
To print a list of fence devices currently available for your cluster, execute the following command:
ccs -h host --lsfenceopts
For example, the following command lists the fence devices available on the cluster node
node1, showing sample output.
ccs -h node1 --lsfenceoptsfence_rps10 - RPS10 Serial Switch fence_vixel - No description available fence_egenera - No description available fence_xcat - No description available fence_na - Node Assassin fence_apc - Fence agent for APC over telnet/ssh fence_apc_snmp - Fence agent for APC over SNMP fence_bladecenter - Fence agent for IBM BladeCenter fence_bladecenter_snmp - Fence agent for IBM BladeCenter over SNMP fence_cisco_mds - Fence agent for Cisco MDS fence_cisco_ucs - Fence agent for Cisco UCS fence_drac5 - Fence agent for Dell DRAC CMC/5 fence_eps - Fence agent for ePowerSwitch fence_ibmblade - Fence agent for IBM BladeCenter over SNMP fence_ifmib - Fence agent for IF MIB fence_ilo - Fence agent for HP iLO fence_ilo_mp - Fence agent for HP iLO MP fence_intelmodular - Fence agent for Intel Modular fence_ipmilan - Fence agent for IPMI over LAN fence_kdump - Fence agent for use with kdump fence_rhevm - Fence agent for RHEV-M REST API fence_rsa - Fence agent for IBM RSA fence_sanbox2 - Fence agent for QLogic SANBox2 FC switches fence_scsi - fence agent for SCSI-3 persistent reservations fence_virsh - Fence agent for virsh fence_virt - Fence agent for virtual machines fence_vmware - Fence agent for VMware fence_vmware_soap - Fence agent for VMware over SOAP API fence_wti - Fence agent for WTI fence_xvm - Fence agent for virtual machines
To print a list of the options you can specify for a particular fence type, execute the following command:
ccs -h host --lsfenceopts fence_type
For example, the following command lists the fence options for the
ccs -h node1 --lsfenceopts fence_wtifence_wti - Fence agent for WTI Required Options: Optional Options: option: No description available action: Fencing Action ipaddr: IP Address or Hostname login: Login Name passwd: Login password or passphrase passwd_script: Script to retrieve password cmd_prompt: Force command prompt secure: SSH connection identity_file: Identity file for ssh port: Physical plug number or name of virtual machine inet4_only: Forces agent to use IPv4 addresses only inet6_only: Forces agent to use IPv6 addresses only ipport: TCP port to use for connection with device verbose: Verbose mode debug: Write debug information to given file version: Display version information and exit help: Display help and exit separator: Separator for CSV created by operation list power_timeout: Test X seconds for status change after ON/OFF shell_timeout: Wait X seconds for cmd prompt after issuing command login_timeout: Wait X seconds for cmd prompt after login power_wait: Wait X seconds after issuing ON/OFF delay: Wait X seconds before fencing is started retry_on: Count of attempts to retry power on
To print a list of fence devices currently configured for your cluster, execute the following command:
