4.27. RHEV-M REST API
Table 4.28, “RHEV-M REST API (RHEL 6.2 and later against RHEV 3.0 and later)” lists the fence device parameters used by
fence_rhevm, the fence agent for RHEV-M REST API.
Table 4.28. RHEV-M REST API (RHEL 6.2 and later against RHEV 3.0 and later)
| luci Field | cluster.conf Attribute | Description |
|---|---|---|
| Name | name | Name of the RHEV-M REST API fencing device. |
| IP Address or Hostname | ipaddr | The IP address or host name assigned to the device. |
| IP Port (optional) | ipport | The TCP port to use for connection with 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. |

| 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. |

Figure 4.20, “RHEV-M REST API” shows the configuration screen for adding an RHEV-M REST API device
Figure 4.20. RHEV-M REST API
The following command creates a fence device instance for an RHEV-M REST API device:
ccs -f cluster.conf --addfencedev rhevmtest1 agent=fence_rhevm ipaddr=192.168.0.1 login=root passwd=password123 \ power_wait=60 ssl=on
The following is the
cluster.conf entry for the fence_rhevm device:
<fencedevices> <fencedevice agent="fence_rhevm" ipaddr="192.168.0.1" login="root" name="rhevmtest1" passwd="password123" \ power_wait="60" ssl="on"/> </fencedevices>
