NOTE:

After an image has been captured from a managed system, a sanity size check is performed on
the captured image to verify that it is valid.

By default, if the captured image size is less than 1,000,000 bytes, the image is considered invalid,
because most operating systems yield an image size greater than that. Typically an image size
less than 1,000,000 bytes indicates that an error occurred that prevented Insight Control for Linux
from capturing the image.

You can change the minimum image size threshold by editing the /opt/mx/icle/
icle.properties

file to change the value of the CAPTURE_IMAGE_MIN_SUCCESS_SIZE

variable; for example:

CAPTURE_IMAGE_MIN_SUCCESS_SIZE=1048575

Setting the CAPTURE_IMAGE_MIN_SUCCESS_SIZE variable to zero overrides the sanity check
and the image size is not checked.

10.4 Preparing for scalable deployment

Scalable Deployment is an optional feature that allows you to deploy a Linux image to a large
number of servers (at least 32) in a short amount of time. However, you must inform Insight
Control for Linux which servers are connected to which switch or

enclosure

beforehand. As

illustrated in

Figure 10-1

, the CMS is connected to other servers through enclosures and switches

(for BladeServers and non-BladeServers respectively). The BladeServers within an enclosure and
the servers connected to a switch form network groups. Each network group has at least one
server that acts as the group leader.
