=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<cfghost> command can be used to configure the RHEV-h host.
|
||
|
|
|
||
|
|
The rhev-h host will register to the rhev-m automatically, but admin needs to
|
||
|
|
approve the host can be added to the 'cluster' with B<-a> flag .
|
||
|
|
|
||
|
|
After registering, the network interfaces of host need to be added to the 'network' of
|
||
|
|
RHEV. And the power management for the host should be configured so that
|
||
|
|
rhev-m could make proper decision when certain host encountered error.
|
||
|
|
|
||
|
|
For each host, an entry should be added to the hypervisor table:
|
||
|
|
|
||
|
|
The columns of hypervisor table:
|
||
|
|
|
||
|
|
=over 2
|
||
|
|
|
||
|
|
B<hypervisor.node> - rhev-h host name.
|
||
|
|
|
||
|
|
B<hypervisor.type> - Must be set to 'rhevh'.
|
||
|
|
|
||
|
|
B<hypervisor.mgr> - The rhev manager (The FQDN of rhev-m server) for the host.
|
||
|
|
|
||
|
|
B<hypervisor.interface> - The configuration for the nics. Refer to B<-n>.
|
||
|
|
|
||
|
|
B<hypervisor.cluster> - The cluster that the host will be added to. The
|
||
|
|
default is 'Default' cluster if not specified.

=head1 OPTIONS
|
||
|
|
|
||
|
|
=over 2
|
||
|
|
|
||
|
|
=item B<-a>
|
||
|
|
Approve the host that to be added to cluster.
|
||
|
|
|
||
|
|
Before approve, the status of the host must be 'pending_approval'.
|
||
|
|
|
||
|
|
=item B<-n>
|
||
|
|
Configure the network interfaces for the host.
|
||
|
|
|
||
|
|
Note: This operation only can be run when host is in 'maintenance mode'.
|
||
|
|
Use B<-d> to switch the host to 'maintenance' mode.
|
||
|
|
|
||
|
|
The interfaces which configured in hypervisor.interface will be added
|
||
|
|
to the network of RHEV.
|
||
|
|
|
||
|
|
The format of hypervisor.interface is multiple [network:interfacename:
|
||
|
|
protocol:IP:netmask:gateway] sections separated with '|'. For example:
|
||
|
|
[rhevm2:eth0:static:10.1.0.236:255.255.255.0:0.0.0.0].
|
||
|
|
|
||
|
|
=over 2
|
||
|
|
|
||
|
|
B<network> - The logic network which has been created by 'cfgve -t nw'
|
||
|
|
or the default management network 'rhevm'.
|
||
|
|
|
||
|
|
B<interfacename> - Physical network name: 'eth0','eth1'...
|
||
|
|
|
||
|
|
B<protocol> - To identify which boot protocol to use for the interface: dhcp
|
||
|
|
or static.
|
||
|
|
|
||
|
|
B<IP> - The IP address for the interface.
|
||
|
|
|
||
|
|
B<netmask> - The network mask for the interface.
|
||
|
|
|
||
|
|
B<gateway> - The gateay for the interface. This field only can be set when
|
||
|
|
the interface is added to 'rhevm' network.

=item B<-p>
|
||
|
|
Configure the power management for the host.
|
||
|
|
|
||
|
|
The power management must be configured for the rhev-h host to make the
|
||
|
|
rhev-m to monitor the power status of the host, so that when certain host
|
||
|
|
failed to function, rhev-m will fail over certain role like SPM to other active host.
|
||
|
|
|
||
|
|
For rack mounted server, the bmc IP and user:password need to be set for the
|
||
|
|
power management (These parameters are gotten from ipmi table). rhev-m uses the
|
||
|
|
ipmi protocol to get the power status of the host.
|
||
|
|
|
||
|
|
=item B<-e>
|
||
|
|
To activate the host.
|
||
|
|
|
||
|
|
=item B<-d>
|
||
|
|
To deactivate the host to maintenance mode.
|
||
|
|
|
||
|
|
=item B<-r>
|
||
|
|
To remove hosts from the rhev-m.
|
||
|
|
|
||
|
|
The host should be deactivate to maintenance mode before the removing.
|
||
|
|
|
||
|
|
=item B<-f>
|
||
|
|
It can be used with B<-r> to remove the target object by force.
|
||
|
|
|
||
|
|
For removing of host, if B<-f> is specified, the host will be deactivated to maintenance before the removing.
|
||
|
