1 file system types, 2 precapture and postcapture scripts – HP Insight Control Software for Linux User Manual

Using the Partition Wizard during image deployment requires an in depth understanding of
Linux, kernel modules, and the grub boot loader.
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
lists the supported and unsupported file system types on the source and target managed
systems for Linux image capture and deployment tasks.
Table 10-1 File system support matrix for image capture and deployment
Unsupported file system types
Supported file system types
Journaling File System (JFS)
ext2
XFS
ext3
VMware file system (VMFS)
ReiserFS
Logical Volume Manager (LVM)
extended partitions
NOTE:
Software RAID is supported in RHEL 4 and RHEL 5 operating systems.
Software RAID is not supported in SLES 10 or SLES 11 operating systems.
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
NOTE:
The Precapture, Postcapture scripts run in the Insight Control for Linux RAM disk. The
managed server'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 server, remember to specify
/mnt/target
in the path; otherwise you will only be 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
