HP Insight Cluster Management Utility v7.2 Release Notes

NOTE: Modify the CMU_CN_WIN_PWD variable in /opt/cmu/etc/cmuserver.conf for setting
user passwords during Windows unattended autoinstall.
• Cloned nodes reboot twice after first disk-boot for host-specific customizations.
• GPT partition table is not supported.
5.11 Ubuntu autoinstall template modifications while using local repository
For Ubuntu, uncomment the live-installer line in the Ubuntu autoinstall template file
(autoinst_ubuntu_cd.templ) before creating an autoinstall logical group. This is only required
while performing a autoinstall from a local repository (created from CD/DVD media).
5.12 Blacklist ahci module before attempting backup or clone of Dynamic
Smart Arrays (B120i RAID mode)
The ahci module loads first before RAID driver (hpvsa) inside the HP Insight CMU netboot
environment during backup and cloning operations. 'ahci' detects B120i (SL4540 Gen8) as a
normal SATA controller and therefore RAID setup is not recognized on nodes. To blacklist 'ahci',
add modprobe.blacklist=ahci to the /opt/cmu/etc/bootopts/default file. This
workaround is necessary only for Dynamic Smart Arrays based on B120i.
For example:
APPEND root=/dev/nfs CMU_CONSOLE ramdisk_blocksize=512 CMU_VENDOR_ARGS ip=::::::bootp modprobe.blacklist=ahci
5.13 Harmless kernel stack trace printed on the compute node vsp while
rebooting from HP Insight CMU netboot environment
The following stack trace is displayed on the vsp when compute nodes are rebooting from the
netboot environment during the end of backup and cloning. This can be ignored.
The system is going down for reboot NOW!
