HP Insight Cluster Management Utility v7.1 Release Notes

4.7 Red Hat 5 update 7 and 8 rsync bug impacts diskless
The rsync executable delivered with rh5u7 (package: rsync-3.0.6-4.el5) and rh5u8 does not
work properly with the command rsync -e ssh. This command causes a failure when creating
a diskless logical group. If you are using the GUI, the following message is returned:
Add Logical Group failed: unknown error occurred while executing /opt/cmu/tools/opt/cmu/tools/cmu_dl_register_image
If you are using the CLI command /opt/cmu/bin/cmu_add_logical_group, the following
messages are returned:
building image from golden node with rsync
usage: ssh [-1246AaCfgkMNnqsTtVvXxY] [-b bind_address] [-c cipher_spec]
[-D [bind_address:]port] [-e escape_char] [-F configfile]
[-i identity_file] [-L [bind_address:]port:host:hostport]
[-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
[-R [bind_address:]port:host:hostport] [-S ctl_path]
[-w tunnel:tunnel] [user@]hostname [command]
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(600) [receiver=3.0.6] script reported (7) i.e. rsync reported
non zero exit code, exiting
To work around this error, remove rsync-3.0.6-4.el5 and install a working package. The rsync
package from rh5u5 ( rsync-2.6.8-3.1 ) works correctly.
4.8 LVM and Software RAID nonsupport
IMPORTANT: Do not install LVM or Software RAID on the HP Insight CMU compute nodes. LVM
or Software RAID on the compute nodes will cause backup or cloning to fail.
TIP: LVM and Software RAID are supported on the management node.
4.9 Fake RAID controller support
HP Insight CMU does not support RAID arrays on compute nodes with fake RAID controllers, for
example smart array B110i/B120i/B320i RAID controllers. Any attempts to backup or clone these
compute nodes will fail.
4.10 Cloning on large-size disks failure
When cloning on large-size disks (for example 750 GB), 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.
4.11 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
