OpenWBEM must be running and configured to start using
OES 2: OpenWBEM Services Administration Guide (http://www.novell.com/documentation/oes2/
mgmt_openwbem_lx_nw/data/front.html).
The CIMOM daemons on all nodes in the business continuity cluster must be configured to bind to
all IP addresses on the server. For information, see

Port 5989 is the default setting for secure HTTP (HTTPS) communications. If you are using a
firewall, the port must be opened for CIMOM communications.
Beginning in OES 2, the Clusters plug-in (and all other storage-related plug-ins) for iManager
require CIMOM connections for tasks that transmit sensitive information (such as a username and
password) between iManager and the
Typically, CIMOM is running, so this should be the normal condition when using the server.
CIMOM connections use Secure HTTP (HTTPS) for transferring data, and this ensures that
sensitive data is not exposed.
If CIMOM is not currently running when you click OK or Finish for the task that sends the sensitive
information, you get an error message explaining that the connection is not secure and that CIMOM
must be running before you can perform the task.
IMPORTANT: If you receive file protocol errors, it might be because WBEM is not running.
To check the status of WBEM:
1 Log in as the user in a terminal console, then enter
root
rcowcimomd status
To start WBEM:

Cluster Services 1.8.6 for Linux Administration
In addition to the shared disks in an original cluster, you need additional shared disk storage in the
other peer clusters to mirror the data between sites as described in
