4.3. Brocade Fabric Switch
Table 4.4, “Brocade Fabric Switch” lists the fence device parameters used by
fence_brocade, the fence agent for Brocade FC switches.
Table 4.4. Brocade Fabric Switch
| luci Field | cluster.conf Attribute | Description |
|---|---|---|
| Name | name | A name for the Brocade device connected to the cluster. |
| IP Address or Hostname | ipaddr | The IP address or host name assigned to the device. |
| 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 parameter. |
| Force IP Family | inet4_only, inet6_only | Force the agent to use IPv4 or IPv6 addresses only |
| Force Command Prompt | cmd_prompt | The command prompt to use. The default value is '\$'. |
| 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 | port | The switch outlet number. |
| Delay (optional) | delay | The number of seconds to wait before fencing is started. The default value is 0. |
| Use SSH | secure | Indicates that the system will use SSH to access the device. When using SSH, you must specify either a password, a password script, or an identity file. |
| SSH Options | ssh_options | SSH options to use. The default value is -1 -c blowfish. |
| Path to SSH Identity File | identity_file | The identity file for SSH. |
| Unfencing | unfence section of the cluster configuration file | When enabled, this ensures that a fenced node is not re-enabled until the node has been rebooted. This is necessary for non-power fence methods (that is, SAN/storage fencing). When you configure a device that requires unfencing, the cluster must first be stopped and the full configuration including devices and unfencing must be added before the cluster is started. For more information about unfencing a node, see the fence_node(8) man page. |
Figure 4.3, “Brocade Fabric Switch” shows the configuration screen for adding an Brocade Fabric Switch fence device.
Figure 4.3. Brocade Fabric Switch
The following command creates a fence device instance for a Brocade device:
ccs -f cluster.conf --addfencedev brocadetest agent=fence_brocade ipaddr=brocadetest.example.com login=root \ passwd=password123
The following is the
cluster.conf entry for the fence_brocade device:
<fencedevices>
<fencedevice agent="fence_brocade" ipaddr="brocadetest.example.com" login="brocadetest" \
name="brocadetest" passwd="brocadetest"/>
</fencedevices>
