Discovering IBM Storage Systems
Before you can discover an IBM storage system, you must install the IBM CIM Agent. For Enterprise
Storage Server (ESS) devices, the CIM Agent is called “CIM Agent for ESS”; for DS devices and
mixed DS and ESS environments, use the “CIM Agent for DS Open (API)”. It is recommended not to
install the IBM CIM Agent on the management server. Refer to the “CIM Agent for DS Open (API) -
Installation and Configuration Guide” for details on configuring the CIM Agent. In short, this
procedure entails:
a. Installing the software. The installation checks for the existence of the ESSCLI. If the
ESSCLI is not installed, installation of the CIM Agent cannot proceed. The ESSCLI is typically
preinstalled on the ESS management server that was configured by the IBM field technician.
b. Configuring the protocol and ports used to communicate with the CIM Agent. You
can change the CIM Agent port value, protocol (HTTP/HTTPS), and enable or disable the
debug option. Unless a secure connection is required between the management server and
the CIM Agent, it is recommended to use port 5988 and protocol HTTP. You must change
the default authentication method in order to discover the CIM Agent. Stop the IBM CIM
Agent service. Then, edit the cimom.properties file in C:\Program
Files\IBM\cimagent by default. Open the cimom.properties file and change the
following property to false:
DigestAuthentication=False
c. Using the setuser command to configure a user to access the CIM Agent. The user
credentials specified here are used to access the CIM Agent and are specified in the
Discovery Step 1. The credentials are not necessarily the same as those used to login to the
ESS Specialist management utility or the DS Storage Manager.
d. Using the setdevice command to configure the ESS and DS devices that are
managed through the CIM Agent. The setdevice command requires a valid user that has
the necessary privileges to access and configure the ESS or DS storage systems.
e. Restarting the IBM CIM Agent service. Restart the IBM CIM Agent service for your
changes to take effect.
f. Verifying that the CIM Agent is able to communicate with the ESS devices.
