Transferring Control of Services

The HP XC System Software provides these commands to transfer control of services to and from the availability tool:

transfer_to_avail
The transfer_to_avail command transfers the control of services from the HP XC system to the availability tool.
transfer_from_avail
The transfer_from_avail command transfers the control of services from the availability tool back to the HP XC system.




	IMPORTANT: You must issue these commands from the head node. Issuing these commands from a node other than head node may result in these commands hanging and not completing.

The following example shows the output of the transfer_from_avail command to transfer the control of services from the HP Serviceguard availability tool to the HP XC system:

# transfer_from_avail
