DESCRIPTION

The chhypervisor command can be used to configure the RHEV-h.

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 -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.

The chhypervisor command can also be used to configure the zVM host.

For each host, an entry should be added to the hypervisor table:

The columns of hypervisor table:

hypervisor.node - rhev-h host name or zVM host name (lower-case).

hypervisor.type - Must be set to ‘rhevh’ or ‘zvm’.

hypervisor.mgr - The rhev manager (The FQDN of rhev-m server) for the host.

hypervisor.interface - The configuration for the nics. Refer to -n.

hypervisor.cluster - The cluster that the host will be added to. The default is ‘Default’ cluster if not specified.

OPTIONS

RHEV specific :

-a Approve the host that to be added to cluster.

Before approve, the status of the host must be ‘pending_approval’.

-n Configure the network interfaces for the host.

Note: This operation only can be run when host is in ‘maintenance mode’. Use -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].

network - The logic network which has been created by ‘cfgve -t nw’ or the default management network ‘rhevm’.

interfacename - Physical network name: ‘eth0’,’eth1’…

protocol - To identify which boot protocol to use for the interface: dhcp or static.

IP - The IP address for the interface.

netmask - The network mask for the interface.

gateway - The gateay for the interface. This field only can be set when the interface is added to ‘rhevm’ network.

-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.

-e To activate the host.

-d To deactivate the host to maintenance mode.

-h Display usage message.

zVM specific :

--adddisk2pool function region volume group

Add a disk to a disk pool defined in the EXTENT CONTROL. Function type can be either: (4) Define region as full volume and add to group OR (5) Add existing region to group. If the volume already exists in the EXTENT CONTROL, use function 5. If the volume does not exist in the EXTENT CONTROL, but is attached to SYSTEM, use function 4.

--addscsi device_number device_path option persist

Dynamically add a SCSI disk to a running z/VM system.

--addvlan name owner type transport

Create a virtual network LAN.

--addvswitch name osa_dev_addr osa_exp_adapter controller connect (0, 1, or 2) memory_queue router transport vlan_id port_type update gvrp native_vlan

Create a virtual switch.

--addzfcp2pool pool status wwpn lun size owner

Add a zFCP device to a device pool defined in xCAT. The device must have been carved up in the storage controller and configured with a WWPN/LUN before it can be added to the xCAT storage pool. z/VM does not have the ability to communicate directly with the storage controller to carve up disks dynamically.

--removediskfrompool function region group

Remove a disk from a disk pool defined in the EXTENT CONTROL. Function type can be either: (1) Remove region, (2) Remove region from group, (3) Remove region from all groups, OR (7) Remove entire group .

--removescsi device_number persist (YES or NO)

Delete a real SCSI disk.

--removevlan name owner

Delete a virtual network LAN.

--removevswitch name

Delete a virtual switch.

--removezfcpfrompool pool lun

Remove a zFCP device from a device pool defined in xCAT.

--smcli function arguments

Execute a SMAPI function. A list of APIs supported can be found by using the help flag, e.g. chhypervisor pokdev61 –smcli -h. Specific arguments associated with a SMAPI function can be found by using the help flag for the function, e.g. chhypervisor pokdev61 –smcli Image_Query_DM -h. Only z/VM 6.2 and older SMAPI functions are supported at this time. Additional SMAPI functions will be added in subsequent zHCP versions.

RETURN VALUE

0 The command completed successfully.

1 An error has occurred.
