Enterprise Manager Agents have to be installed on Oracle Solaris global zones of both MiniCluster compute nodes. You can install EM Agents into Oracle Solaris Global and Non-Global Zones using Add Host Targets wizard.
The following are the credentials required for the discovery of Oracle MiniCluster.
Systems Infrastructure Server
ILOM Monitoring Credentials, SNMP Credentials
Required to monitor MiniCluster compute nodes through their ILOMs
To discover the Oracle MiniCluster system, perform the following steps:
To enable monitoring of Oracle VM for SPARC the non-privileged user used to install and run the Enterprise Manager agent must be granted the solaris.ldoms.read and solaris.ldoms.ldmpower authorizations and be assigned the LDoms Power Mgmt Observability rights profile.
/usr/sbin/usermod -A solaris.ldoms.read,solaris.ldoms.ldmpower oracle
/usr/sbin/usermod -P 'LDoms Power Mgmt Observability' oracle
The guided discovery process assumes that Oracle Enterprise Manager Agents are already deployed to Oracle Solaris Global zones of the MiniCluster Compute Nodes. The Enterprise Manager agent must be deployed in order to discover MiniCluster system, monitor disk shelves and a virtualization stack on compute nodes.
If you want to monitor database instances running on a DB domain, you must install the Enterprise Manager Agents on all the Zones where the databases are installed.
Before you are taken to the Review screen, a validation is executed to find out if the correct agent for Disk Shelf Monitoring was selected. This agent has to be deployed to the host which Disk Shelf is directly connected using Serial Attached SCSI. If you selected an agent on another host where Disk Shelf is not directly connected, you will get a warning. You have to select the correct agent first otherwise you cannot proceed in MiniCluster discovery. After the Disk Shelf agent selection validation, another validation is executed. This validation checks if you correctly configured Solaris host so you can see hardware related incidents in Enterprise Manager. You can see result of this validation on the Review screen. If the Solaris Host is not configured properly to deliver incidents, you won't see FMA alerts with Disk Shelf failures as incidents in Enterprise Manager. This configuration is not mandatory to finish MiniCluster discovery but highly recommended. For information on how to configure incidents for Solaris Host, see Configuring Snmp traps for Supercluster and Minicluster monitored hosts.
Find the EM agent numeric IP address and port number.
Login to the host where the EM agent is deployed. From the agent directory
<AGENT_HOME>/bin run the following command to obtain the port number of the agent:
$ emctl status agent | grep 'Agent URL' Agent URL: https://hostname.domain:3863/emd/main/
The port number can be seen after the fully qualified domain name of the agent, it is 3863 in the example above.
To get the numeric IP address, use ping or
Configure the snmpd.
trap2sink entry information into the
snmpd.conf configuration file.
The configuration file
snmpd.conf is in different location for Solaris 10 and Solaris 11.
trap2sink <numericip> public <transport>where,
The <transport> is the port number obtained in step (1). It is the port number of the EM agent.
The <numericip> is the IP address of the EM agent host, obtained in step (1).
trap2sink 10.133.249.68 public 3863
Restart the SNMP services.
svcadm restart net-snmp svcadm restart snmp-notify
svcadm restart sma
If the SNMP service was not enabled before, ensure that the services are enabled.
svcadm enable net-snmp svcadm enable snmp-notify
svcadm enable sma
Optionally, verify the snmpd configuration by making sure the status for Telemetry Status is ON in the host target, in the Telemetry Alert Config metric.
Select Host and click Configuration.
Click Last collected.
Select Telemetry Alert Config metric.
Click Refresh, wait for few minutes until the metrics get refreshed.
If the Telemetry Status is ON in Telemetry Alert Config metric, it indicates the the configuration of FMA SNMP traps is done correctly.
