HP Insight Control for Linux 6.0 Release Notes

• Ensure that the selected boot partition matches the boot partition in captured image.
If you use the Partition Wizard to specify a different disk partitioning scheme, the bootable
partition (typically /boot or /) must be the same partition as in the captured image.
This is typically the first partition (partition 0) for RHEL distributions, but the second partition
(partition 1) for SLES distributions.
• If you use the Partition Wizard to change the storage layout for RHEL image deployments
using logical volumes, ensure that the first volume group is named VolGroup00. This value
is coded into the initial RAM disk (initrd*.img) to activate logical volumes, and the initial
RAM disks are not remade by Deploy Linux Image.
It is possible to remake the initial RAM disk as part of a post-installation script.
• Do not to allocate more storage than is available on the disk or is within a defined volume
group. This can be best accomplished by always defining a partition (or logical volume if
using LVM) that uses the available space or is growable. You must ensure that the partitions
and logical volumes are sized properly to fit within the free space.
• Partitions used for logical volumes must be in the first four disk partitions. If there are five
or more partitions, the logical volume must be in the first three disk partitions.
This limits the maximum number of partitions that can be used for volume groups to three
(if only four partitions are created) or two (if more than four partitions are created).
3.3.6 Correction to Chapter 14, Using graphical tools to monitor managed systems
This paragraph in section 14.3.1 needs correction:
In Figure 14-4, one host is down. Select the link in that box to open the Host Status Details window
for that host, which identifies the hosts and provides some status information about them.
Replace it with the following text, including the Note:
In Figure 14-4, two hosts are down. Select the link in that box to open the Host Status Details
window for that host, which identifies the hosts and provides some status information about
them.
NOTE: The standard Nagios Tactical Overview display uses the color red to highlight ‘Disabled’
services. To illustrate, in Figure 14–4, in the Active Checks column, the message 21 Services
Disabled is displayed on a red field.
A disabled service is a configuration status, not an error condition. Insight Control for Linux
takes advantage of the Nagios passive check feature to optimize and to minimize data collection
and reporting across large numbers of managed systems.
HP recommends that administrators do not enable these services because they are not intended
to run under normal conditions and will cause Nagios to generate false alerts.
3.3.7 Correction to Chapter 17, Remote server controls
The title for section 17.4 should be HP Insight Control power management.
3.3.8 Addition to Chapter 21, Miscellaneous tasks
Section 21.4, Changing the IP address of the CMS, is missing the following NOTE:
NOTE: If the CMS is the DHCP server, you must edit the /etc/dhcpd.conf file to specify
the new IP address for the next-server and option-140 options.
The information in Section 21.9.2, Restoring Operation After a Firmware Upgrade, is out of date
and should be removed.
