HP XC System Software Administration Guide Version 3.1

2.5 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
