HP Insight Cluster Management Utility v7.2 Release Notes

5.7 B110i RAID mode support
HP Insight CMU does not support RAID arrays created by B110i RAID controllers (e.g. SL4545
G7). Any attempts to backup or clone such RAID arrays will fail.
5.8 Cloning on large-size disks failure
When cloning on large-size disks (for example 750GB), the cloning process fails and displays the
following:
Cloning finished, 0 nodes cloned, 0 nodes finished
To work around this error, edit the /opt/cmu/etc/cmuserver.conf file and then set the
CMU_NO_STATUS_CHANGE_TIMEOUT variable to a value that enables you to format disks. For
example:
CMU_NO_STATUS_CHANGE_TIMEOUT=7200
This example sets the timer to 2 hours.
5.9 The colplot HTML files are lost on HP Insight CMU rpm uninstall
Uninstalling HP Insight CMU erases /opt/cmu/www along with the HTML files in /opt/cmu/
www/colplot. History data is not affected if the /opt/cmu/www directory is not used as a
common collectl directory for compute nodes.
To work around this issue, copy the files from the original colplot directory to /opt/cmu/www
after the new HP Insight CMU installation.
• On Red Hat:
# cp -a /var/www/html/colplot /opt/cmu/www/colplot
• On SUSE:
# cp -a /srv/www/htdocs/colplot /opt/cmu/www/colplot
5.10 Backup and cloning of Windows images
IMPORTANT: The Windows backup and cloning feature is supported only on specific Moonshot
cartridges. None of the other server types are supported.
Backup and cloning of Windows images have the following limitations:
• HP Insight CMU can backup and clone only one disk per compute node.
• The Windows golden node must be shutdown gracefully before attempting a backup operation.
• The golden image size (the total size of compressed part-archi*.tar.bz2 files) must be
less than 85% of RAM size on the nodes to be cloned. For example, on nodes with 8GB RAM,
the maximum image size that can be cloned is approximately 7GB. A simple Windows install
image when compressed is usually about 3GB. Windows unattended autoinstall does not
have this limitation.
• Windows dynamic disks are not supported. Only Windows basic disks are supported.
• When multiple (>1) primary and (>1) logical partitions are present in a Windows backup
image, drive letters (e.g. D:, E: ) assigned to the partitions on the cloned nodes are not
consistent with the golden node.
• Local "Administrator" account password and desktop is reset on cloned nodes. Any content
placed in the "Administrator" desktop directory is lost after cloning. Other local user accounts
are not affected. Always configure additional local user accounts with administrator privileges
on the golden node. The default HP Insight CMU autoinstall template for the golden node
automatically adds a "CMU" user account with administrator privileges.
