HP XC System Software Administration Guide Version 3.1

For additional information about the startsys command, see startsys(8).
The following sections provide procedures for starting nodes that do not need imaging, for imaging and
starting nodes, and for restarting a node to image it.
3.2.1 Starting All Nodes
The following procedure describes the steps necessary to start the HP XC system from the head node. In
this procedure, all the enabled nodes that do not require imaging are booted. “Disabling and Enabling a
Node” (page 53) describes how nodes are enabled and disabled.
1. Log in as superuser (root) on the head node.
2. Start all nodes on the system with the startsys command:
# startsys
Alternatively, you can specify a single node or a list of nodes.
3. If your system has been configured for improved availability, enter the transfer_to_avail
command to transfer control to the availability tool:
# transfer_to_avail
For additional information on options that affect booting, see startsys(8).
3.2.2 Determining Which Nodes Require Imaging
The startsys command features a --test option, which returns a list of nodes that require imaging,
as shown here:
# startsys --test
Enabled nodes: n[9-16]
Removing the execution node: n16
Boot hierarchy of specified nodes is: n15 n[9-14]
Nodes that require imaging - use --image_and_boot -> n[13-14]
Test completed.

3.2.3 Imaging and Starting Nodes
The following procedure describes the steps necessary to start the HP XC system from the head node. In
this procedure, all the enabled nodes that need imaging are imaged, then the enabled nodes are booted.
1. Log in as superuser (root) on the head node.
2. Invoke the startsys command with the --image_and_boot option:
# startsys --image_and_boot
3. If your system has been configured for improved availability and the nodes that provide availability
have been reimaged, enter the transfer_to_avail command to transfer control to the availability
tool:
# transfer_to_avail
For additional information on options that affect imaging, see startsys(8).
3.2.4 Restarting a Node for Imaging
The following procedure describes how to image and boot a node that is already running. In this instance,
the node needs to be imaged to accommodate a recent update to the golden image.
1. Log in as superuser (root) on the head node.
2. Invoke the startsys command with the --force and --image_and_boot options:
