HP Insight Cluster Management Utility v7.2 User Guide

2.2 Preparing for installation
2.2.1 HP Insight CMU kit delivery
The HP Insight CMU kit is delivered on CD-ROM and is provided in the appropriate format for
your operating system. These features enable HP Insight CMU files to be installed directly from the
CD-ROM to your disk. The Linux versions of HP Insight CMU are in the Red Hat Package Manager
(RPM) format.
2.2.2 Preinstallation limitations
• HP Insight CMU monitors only the compute nodes and not the infrastructure of the cluster.
• For cloning Linux images:
HP Insight CMU requires that each partition of the golden image node is at least 50%
free. Alternatively, if this condition cannot be satisfied, then the largest partition of the
golden node must be less than or equal to the compute node memory size.
◦
◦ HP Insight CMU does not support software RAID or LVM on compute nodes.
◦ HP Insight CMU only clones one disk or logical drive per compute node.
• Limitations for backup and cloning Windows images:
The Windows backup and cloning feature is supported only on specific Moonshot
cartridges. No other platforms are supported.
◦
◦ 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 available for cloning is approximately 7GB. A
simple Windows install image is usually approximately 3GB when compressed.
NOTE: 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.
◦ The local “Administrator” account password and desktop are reset on cloned nodes. Any
content placed in the “Administrator” desktop directory is lost after cloning.
◦ Cloned nodes reboot twice after the first disk-boot for host specific customizations.
◦ GPT partition table is not supported.
IMPORTANT: 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.
NOTE: You can partially overcome some of these limitations by using a reconfiguration script
after cloning. For more information about reconfiguration, see “Reconfiguration” (page 63).
