HP Insight Control Software for Linux - Manual (Page 112)

f. Select Save As Collection...
The Save As Collection portion appears.
g. Enter a name for this network group.
The name is used only to associate the managed systems in the network group.
h. Select Existing collection: and choose the Network Groups menu item.
i. Select OK to continue.
j. Generate the netgroups.conf file with the following command:
# /opt/hptc/bin/netgroup --ofile /opt/mx/icle/netgroups.conf
k. Examine the netgroup.conf file to verify the collection entry for the group.
If the name of the group is Switch1 and the servers that comprise it are n1, n3, n4, and
n5
, the netgroups.conf file contains a line similar to the following:
Switch1=n1 n3 n4 n5]
By default, scalable deployment images one leader per network group, up to 16 groups at a time,
and each leader can, in turn, image 16 managed systems at a time within its network group. If
you want to change this behavior, edit the /opt/mx/icle/icle.properties file to add any
of the following variables, as needed. You do not need to restart Insight Control for Linux for these
changes to take effect.
Table 18 Scalable deployment environment variables
Default value Description Variable
1 Number of leaders per network group. LSD_NUM_LEADERS_PER_GROUP
16 Number of leaders imaged concurrently. LSD_MAX_LEADERS_AT_ONCE
16 Number of managed systems that a leader can
image concurrently. LSD_MAX_DOWNLOADERS_PER_LEADER
The number of group leaders that start imaging concurrently depends on the values of
LSD_NUM_LEADERS_PER_GROUP
and LSD_MAX_LEADERS_AT_ONCE variables. For example,
if the value of LSD_NUM_LEADERS_PER_GROUP is 1 and the value of
LSD_MAX_LEADERS_AT_ONCE
is 16 (these are their default values), then 16 leaders (each in a
different network group) start imaging concurrently. If, however, the value of
LSD_NUM_LEADERS_PER_GROUP
is 2, the leaders in the first 8 network groups start imaging
concurrently because each group has 2 leaders and the maximum leaders at once is set to 16.
After the image is downloaded from the CMS, the leader starts to image the managed systems in
its network group. The leader images as many managed systems as the value of the
LSD_MAX_DOWNLOADERS_PER_LEADER
variable. If there is more than one leader in the network
group, each leader images as many managed systems as the value of
LSD_MAX_DOWNLOADERS_PER_LEADER
.
A leader does not reboot until all the managed systems in its network group are imaged, failed,
or cancelled.
10.5 Deploying a captured Linux image to one or more managed system
Insight Control for Linux enables you to deploy a captured Linux image from one managed system
to one or more managed systems.
The Deploy Linux Image... task shuts down the managed systems and reboots them. The RAM disk
starts the image deployment.
