Seeing the information you pasted, you have both the more recent Unisphere Host Agent and the older Navisphere Agent installed on the Linux host.  Unlike Windows, Linux will not prevent you from doing so (or in other words, Windows will detect the transition from Navisphere Agent to Unisphere Hostagent as an upgrade).  There is no reason to have both installed on the server.   usao wrote:  On the non working box it's running  Since you already have hostagent running and bound to port TCP/6389, your attempts to start naviagent will fail as noted by the bind() error message in the kernel logs.  I would uninstall naviagent.  Please note, there isn't any reason you have to match the version of the agent with the version of Navisphere Manager or Unisphere Manager running on the storage processors.  For instance, the latest version of Unisphere Host Agent v1.2 provides the following details:  /etc/Unisphere/SupportedFlareRevisions  [...] CX_Software >= 2.26 AND CX_Software < 2.33 [...]  Also, if you visit support.emc.com and select either a CX3 or CX4 as your array model and select Downloads, you will see the latest Unisphere Host Agent in the list (assume that the site is properly filtering only the relevant choices based on your array, but worth double-checking).   Lastly, not related to the original question, your agent.config file (/etc/Unisphere) is missing entries for privileged users (local or remote) that can run CLI commands against the agent.  Notably you are missing reference to both of the storage processors which query the agent on a regular interval.  Add the following to the file:  user system@  user system@  <blank line or in other words CR on last line if EOF>  As a reminder, any changes to configuration files will require restarting the agent.  This may explain why you are gettings certain details from one but not the other.  HTH
I have several RHEL hosts, some run the naviagent fine, others won't start for unknown reasons. I could use some advice on how to get naviagent running on the boxes which currently won't run the agent. Some of these hosts run Powerpath, some run native Linux multipathing. Details below.
