2. Use the startsys command to turn on power to all nodes, image the nodes, and boot the nodes. As
shown in Table 3-9, the command-line options for the initial system image and boot depend upon the
size of the system. See startsys( 8) for the complete list of command options.

300 Nodes?Description
startsys Command-Line
Option
NoYesImages and then reboots all nodes so they complete their
per-node configuration phase, thus completing the installation
on the nodes. This option applies only for nodes that have
previously been set up to network boot.
--image_and_boot
YesNoCompletes the imaging phase and then halts the nodes before
their per-node configuration phase. For large-scale systems,
booting while imaging is not recommended.
--image_only
3. Use this startsys command on systems with fewer than 300 nodes to image and boot all nodes.
For larger hardware configurations, use the command shown in step 4.
# startsys --image_and_boot
4. Use these startsys commands on systems with more than 300 nodes. The image and boot process
is completed in two phases:
a. Image the nodes:
# startsys --image_only
b. Boot the nodes:
# startsys --boot_group_delay=240
NOTE: Use the --boot_group_delay=240 option only the first time nodes are booted after
being imaged; the value 240 specifies the number of seconds to wait between groups of nodes
as they are booting. For more information about this value, see startsys(8)
5. If you want to watch as the startsys command images and powers on nodes, open a second terminal
window and issue a tail command to view the following log files:
• /hptc_cluster/adm/logs/imaging.log
• /hptc_cluster/adm/logs/startsys.log
Command output on a small, 16-node configuration is similar to the following:
# startsys --image_and_boot
Thu Sep 28 08:49:10 2006 Enabled nodes: 16 nodes -> n[1-16]
Thu Sep 28 08:49:12 2006 Removing the execution node: n16
Thu Sep 28 08:49:12 2006 Boot hierarchy of specified nodes is: n15 n[1-14]
Thu Sep 28 08:49:15 2006 Initial power test - please wait.
Thu Sep 28 08:49:24 2006 Nodes that will image: 15 nodes -> n[1-15]
You must manually power on the following nodes:
n1
Press enter after applying power to these nodes.

Thu Sep 28 08:49:29 2006 Powering on for image: 14 nodes -> n[2-15]
Thu Sep 28 08:50:34 2006 Retrying power --on command: 3 nodes -> n[2-3,15]
