HP Insight Control Software for Linux - Manual (Page 104)

NOTE: To account for the time it may take to capture or deploy a very large image over a slow
network, a time out of five days is in effect for capturing or deploying a Linux image so that you
can determine if an operation hangs. HP recommends that you check your task results to verify the
status of any running jobs.
10.1.1 File system types
Table 16 lists the supported and unsupported file system types on the source and target managed
systems for Linux image capture and deployment tasks.
Table 16 File system support matrix for image capture and deployment
Unsupported file system types Supported file system types
• Journaling File System (JFS) • ext2
• •
ext3 XFS
• • VMware file system (VMFS) ext4
•
ReiserFS
•
Logical Volume Manager (LVM)
• extended partitions
NOTE: Insight Control for Linux supports capture and deployment of RHEL 4 and RHEL 5 systems
installed with Software RAID. However, Insight Control for Linux does not support capture and
deployment of RHEL 6, SLES 10, and SLES 11 systems installed with Software RAID.
10.1.2 Precapture and postcapture scripts
Precapture scripts provide a streamlined ability to prepare or sanitize (that is, to remove confidential
data) a managed system’s image before capturing it.
You can use a Postcapture script to undo what a Precapture script does, or to perform some other
action afterward.
Precapture and Postcapture scripts are Linux shell scripts; for more information on adding, removing
and managing them, see
Section 5.2.5 (page 50) .
The Precapture, Postcapture scripts run in the Insight Control for Linux RAM disk. The managed
system's file system is mounted as read/write in the RAM disk under the /mnt/target mountpoint.
If your scripts manipulate any files on the managed system, remember to specify /mnt/target
in the path; otherwise you are only manipulating the RAM disk files.
You can use any script that is registered and copied to the repository. Insight Control for Linux also
creates the /tmp/variables.txt file on a managed system, which contains hardware specific
information about the server. The script can source this file ( . /tmp/variables.txt) to load
information determined by the RAM disk about the current operating environment.
The /tmp/variables.txt file contains shell variables of the form VARIABLE="value". The
most important variables are:
HOSTNAME
DOMAINNAME
DEVICE
IPADDR
NETMASK
NETWORK
BROADCAST
GATEWAY
GATEWAYDEV
IMAGESERVER
