Configure SNMP Trap Destinations for Storage Servers

Perform this task on each storage server:

1. Log in as celladmin on the storage server.
2. On the storage server, add SNMP trap destinations:

   # cellcli -e “alter cell snmpSubscriber=(host ='ASR-Manager-name-or-IP-address',port=162,community=public,type=asr)”

   Single quotes are required around the ASR-Manager-name-or-IP-address entry. These are the element definitions for the command above:

   • host='ASR-Manager-name-or-IP-address' – The ASR Manager hostname can be used when DNS is enabled for the site. If DNS is not running, the IP address is preferred, but the ASR Manager hostname can be used if the entry is added to the /etc/hosts file.

   • type=asr – Specifies the ASR Manager as being a special type of SNMP subscriber.

   • community=public – The required value of the community string. This value can be modified to be a different string based on your network requirements.

   • port=162 – The SNMP port. This port value is site dependant. It can be configured as a different port based on network requirements, or it might need to be changed for ASR to work correctly in a managed environment.

3. Ensure that Oracle ILOM auto-activation occurred

   This confirms that the network and Oracle ILOM are set up correctly.

   # asr list_asset

   Example:

   IP_ADDRESS     HOST_NAME       SERIAL_NUMBER   ASR       PROTOCOL   SOURCE
   ----------     ---------       -------------   ---       --------   -----
   10.60.40.105   ssc1cel01       1234FMM0CA      Enabled   SNMP       ILOM
   10.60.40.106   ssc1cel02       1235FMM0CA      Enabled   SNMP       ILOM
   10.60.40.107   ssc1cel03       1236FMM0CA      Enabled   SNMP       ILOM
   10.60.40.117   ssc1cel01-ilom  1234FMM0CA      Enabled   SNMP,HTTP  EXADATA-SW
   10.60.40.118   ssc1cel02-ilom  1235FMM0CA      Enabled   SNMP,HTTP  EXADATA-SW
   10.60.40.119   ssc1cel03-ilom  1236FMM0CA      Enabled   SNMP,HTTP  EXADATA-SW

   • If all Oracle ILOMs for the storage servers are in the list, go to Step 5.

   • If Oracle ILOMs are not in the list, go to Step 4.

4. On the ASR Manager, activate the Oracle ILOMs of the storage servers:

   # asr activate_asset -i ILOM-IP-address

   or

   # asr activate_asset -h ILOM-hostname

   ---

   Note - If the last step fails, verify that port 6481 on the Oracle ILOM is open. If port 6481 is open and the step still fails, contact ASR Support.

   ---

5. Activate the Exadata OS side of the ASR support:

   # asr activate_exadata -i host-management-IP-address -h host-management-hostname -l ILOM-IP-address

   or

   # asr activate_exadata -i host-management-IP-address -h host-management-hostname -n ILOM-hostname

6. Ensure that all storage servers are visible on the ASR Manager.

   # asr list_asset

   You should see both the Oracle ILOM and the host referenced in the list, with the same serial number, as shown in this example:

   IP_ADDRESS     HOST_NAME       SERIAL_NUMBER   ASR       PROTOCOL   SOURCE
   ----------     ---------       -------------   ---       --------   -----
   10.60.40.105   ssc1cel01       1234FMM0CA      Enabled   SNMP       ILOM
   10.60.40.106   ssc1cel02       1235FMM0CA      Enabled   SNMP       ILOM
   10.60.40.107   ssc1cel03       1236FMM0CA      Enabled   SNMP       ILOM
   10.60.40.117   ssc1cel01-ilom  1234FMM0CA      Enabled   SNMP,HTTP  EXADATA-SW
   10.60.40.118   ssc1cel02-ilom  1235FMM0CA      Enabled   SNMP,HTTP  EXADATA-SW
   10.60.40.119   ssc1cel03-ilom  1236FMM0CA      Enabled   SNMP,HTTP  EXADATA-SW

7. On the storage server, validate the configuration:

   # cellcli -e “list cell attributes snmpsubscriber”

8. On the storage server, validate the SNMP configuration:

   # cellcli -e “alter cell validate snmp type=asr”

   The MOS contact receives an email as confirmation.

9. Repeat these instructions for every storage server in your SuperCluster.
10. Go to the next configuration task.
