Table 6-4 startsys Command-Line Options Based on Hardware Configuration
startsys Command LineHardware Configuration
For small-scale hardware configurations, nodes are imaged and rebooted
in one operation. The nodes complete their per-node configuration
phase, thus completing the installation. This option applies only for
nodes that have previously been set up to network boot.
Enter the following command to image and boot all nodes in one step:
# startsys --image_and_boot
Fewer than 300 nodes
For large-scale hardware configurations, booting nodes while imaging
is not recommended. Thus, issue the following commands to image
and boot nodes in two separate steps:
1. Propagate the golden image to all nodes:
# startsys --image_only
2. Boot all 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.
More than 300 nodes
If the hardware configuration contains HP server blades, booting nodes
while imaging is not recommended, and additional options are required
on the command line. Issue the following commands to boot and image
all nodes:
1. Propagate the golden image to all nodes:
# startsys --image_only --flame_sync_wait=480 \
--power_control_wait=90 \
--image_timeout=90
2. Boot all nodes when the imaging process is complete:
# startsys --power_control_wait=90 \
--boot_group_delay=45 \
--max_at_once=50
Contains HP server blades and
enclosures
If the hardware configuration contains disks that are 250 GB or larger
in size or contains SATA disks, you might need to increase the 45 minute
default allowed for imaging by the startsys command.
For example, on systems with disks larger than 250 GB, increase the
image timeout limit to 60 minutes, as follows:
# startsys --image_and_boot --image_timeout=60
You might use a different value depending upon the size of the disks
in the system.
Nodes have disks that are 250 GB or
larger in size or have SATA disks

startsys(8).
5. If you want to watch as the startsys command images and turns on power to the nodes,
open a second terminal window and run the 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:
Fri Dec 05 08:49:10 2008 Enabled nodes: 16 nodes -> n[1-16]
Fri Dec 05 08:49:12 2008 Removing the execution node: n16
Fri Dec 05 08:49:12 2008 Boot hierarchy of specified
nodes is: n15 n[1-14]
Fri Dec 05 08:49:15 2008 Initial power test - please wait.
Fri Dec 05 08:49:24 2008 Nodes that will image:
15 nodes -> n[1-15]
