HP Insight Cluster Management Utility v7.1 Release Notes

4 Limitations and workarounds
4.1 HP iLO CM ssh/vsp connections are limited to 15
Each HP iLO CM zone allows up to 15 concurrent ssh/vsp sessions. To go beyond that limit, close
old connections before starting new connections.
Starting new ssh/vsp connections to HP iLO CM from the HP Insight CMU GUI or cmu_console
tool can be slow, resulting in connection timeout errors. To eliminate these errors, increase the
CMU_CONSOLE_CONNECTION_TIMEOUT value in /opt/cmu/etc/cmuserver.conf.
4.2 Renamed autoinstall logical groups must be manually changed in
/etc/exports
When an existing autoinstall logical group is renamed using the HP Insight CMU GUI, the
corresponding entry in the /etc/exports file is not automatically updated on the management
node. Manually edit the /etc/exports file after renaming the autoinstall logical group.
4.3 Backup process fails on some golden nodes running SLES10
Backup failures on SLES10 are mainly seen on nodes with SATA LFF Western Digital disks and
non-smart array controllers. To work around this failure, manually replace all the disk partition ID
entries in /etc/fstab and /boot/grub/menu.lst files on the golden node with device names
(such as /dev/sda2, /dev/cciss/c0d0p2, and so on) before starting the backup operation.
4.4 RHEL6.x diskless boot failure
RHEL6.x diskless nodes fail to boot when NetworkManager service is enabled in the diskless image.
Disable NetworkManager service on the golden node before creating the diskless image. For
example:
chkconfig --level 345 NetworkManager off
4.5 Diskless unavailable on Ubuntu compute nodes
Ubuntu is supported only on compute nodes. Diskless environments require that the compute nodes
share the operating system on the HP Insight CMU management node.
4.6 SLES11 SP2 diskless logical group boot failure
Compute nodes booting in a SLES11SP2 diskless logical group cause a kernel panic during boot.
To work around this issue:
1. Delete the failing diskless logical group.
2. Verify that initrd is deleted for this group on the head node:
pxeos -l
ls /tftpboot/linux-install/
3. Remove the nfs-client rpm from the SLES11SP2 golden node:
rpm -ev nfs-client --nodeps
4. Install the nfs-client rpm from SLES11 SP1 (DVD or ISO) on the golden node:
rpm -ivh nfs-client-1.2.1-2.6.6.x86_64.rpm
5. Create a diskless image from the golden node.
6. Boot a node with the new diskless image.
