Replacing IBM Flex Systems EN4093R Switch I/O Module

This procedure disrupts communication on the local area network (LAN) fabric for all devices attached to the EN4093R switch that is being replaced. Ensure that you take preventive steps in the affected environment to mitigate the effects of this disruption.

1. Take a backup of the current switch configuration. For information on how to back up the configuration, see the General Configuration Commands table in the IBM Flex System® Fabric EN4093/EN4093R 10Gb Scalable Switch ISCLI Command Reference.
2. In the IBM Flex System Manager management software Web User Interface, remove the Switch Managed End Point (MEP) that is associated with the switch I/O module that is being replaced. To remove the MEP:
   1. Right click the switch MEP.
   2. Select Remove.
3. Replace the existing EN4093R switch I/O module with the new I/O module. For information on how to replace the existing EN4093R switch, see the Installing and removing the switch module section in the IBM Flex System Fabric EN4093 and EN4093R 10 Gb Scalable Switch User's Guide.
   Note: If feature licenses exist on the switch that is being replaced, acquire and install new activation key files based on the serial number of the replacement unit. If the replacement is handled through IBM Service and Support, your original authorization Code is transferred to the serial number of the replacement unit. If needed, contact IBM Features On Demand license key support, by sending an email to: FOD@us.ibm.com to request activation keys for the option. Refer to the IBM Flex System Fabric EN4093/EN4093R 10Gb Scalable Switch ISCLI Command Reference , Feature on Demand Key Options section, for key file installation details.
4. Configure the Network address by using the Chassis Management Module (CMM).
5. Restore the switch configuration. For information on how to restore the switch configuration, see the General Configuration Commands table in the IBM Flex System Fabric EN4093/EN4093R 10Gb Scalable Switch ISCLI Command Reference. If a backup is not available, refer to the Command Reference for further information on how to configure the switch.
6. Discover the replacement switch module by running an IBM Flex System Manager management software Inventory task against the CMM. To discover the replacement switch module, complete the following tasks:
   1. Log in to the IBM Flex System Manager management software Web User Interface.
   2. Right click the System Chassis MEP of the chassis that contains the replacement switch.
   3. Select Inventory → Collect Inventory from the menu.
   4. Select Run now and click OK in the Launch Job window. This action starts a chain of inventory jobs that begin with a single Collect Inventory job for the CMM in the chassis. When this action is complete, a number of other inventory jobs are automatically created based on the information that is obtained from the CMM inventory.
      Note: Complete all the additional inventory jobs before you continue with the next step. To monitor these jobs in the IBM Flex System Manager management software Web User Interface, go to the Home tab and select the Plug-ins subtab. Under the Automation Manager plug-in section, click the Active and Scheduled Jobs link. The Active and Scheduled Jobs pane is started from where all the inventory jobs can be monitored. Further information about inventory with the IBM Flex System Manager management software is in Discovering systems and collecting inventory data.
7. A Switch MEP for the replacement switch now appears in the IBM Flex System Manager management software Web User Interface. If the switch does not appear, manually discover it by using the SNMP protocol. Information on how to discover the replacement switch as a Switch MEP are in Section 3 of technote 618408331 , A Switch is Not Discovered as a Switch in IBM Systems Director Due to Incorrect SNMP Credential Used.
8. The new Switch MEP is in an OK access state.
9. Perform a full FSM inventory on the replacement switch. To complete the full inventory by using the IBM Flex System Manager management software Web User Interface,
   1. Right click the Switch MEP for the replacement switch.
   2. Select Inventory → Collect Inventory.
   3. Select Run now and click OK in the Launch Job window. The replacement switch is ready for use when the Inventory job completes successfully.
