HP Insight Control for Linux 6.2 User Guide

• For SLES images, change the hard links to soft links before capturing the image.
SLES relies on the use of hard links within its file system, and the tar command that captures
the image captures those hard links.
If a partitioning scheme is used during deployment that distributes files to multiple file
systems (like separate /usr and /var partitions), the tar command does not allow hard
links to be established across separate file systems. This generates an error, causing the task
to fail.
• Follow these guidelines when you capture a Linux OS from a managed system with multiple
disks:
— Each disk you want to capture must have at least one partition. Disks mounted with
no partitions are not supported.
— You must modify the /etc/fstab file to include the mount points of all partitions on
the disks you want to capture.
Because disks are repartitioned during an image deployment operation, you must
ensure that the contents of the disks you want to capture are listed correctly in the
/etc/fstab file.
For a capture operation to be successful, the dump field for each partition to be captured
must be set to 1. The dump field is the fifth field in the standard mount line. Setting
this field to 1 enables the partition to be captured, and setting this field to 0 (zero)
bypasses the capture.
Example 10-1 provides an example of a sample /etc/fstab file. In Example 10-1, two
additional serial SCSI disks are located on the source system (/dev/cciss/c0d1 and
/dev/cciss/c0d2), and the system disk resides on /dev/cciss/c0d0.
IMPORTANT: For the capture operation to be successful,/dev/cciss/c0d1 and
/dev/cciss/c0d2 must be partitioned, and the dump flag must be set to 1.
Example 10-1 /etc/fstab file entries for a managed system with multiple disks

Using the last line in Example 10-1 as a sample, the following table describes each field
in the mount line for device /dev/cciss/c0d2p1.
