Replacing IBM Flex Systems FC3171 Switch I/O Module

This procedure disrupts communication on the storage area network (SAN) fabric for all devices that are attached to the FC3171 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 IBM Flex System® FC3171 8 Gb Pass-thru Command Line Interface User's Guide , section Backup and restore a switch configuration or by using the steps that are described in the IBM Flex System FC3171 8 Gb Pass-thru QuickTools User’s Guide , section Archiving a switch.
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 FC3171 switch I/O module with the new I/O module. For information on how to replace the existing FC3171 switch, see IBM Flex System Manager® Types 7955, 8731, and 8734 Installation and Service Guide, sections Removing an I/O module and Replacing and I/O Module
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 IBM Flex System FC3171 8 Gb Pass-thru Command Line Interface User's Guide , section Backup and restore a switch configuration or by using the steps that are described in the IBM Flex System FC3171 8 Gb Pass-thru QuickTools User’s Guide , section Archiving a switch. If a backup is not available, refer to the guides 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. If the switch is in a Partial access state, follow the procedure in technote 701591432, A method for correcting an IBM Flex Systems FC3171 switch I/O Module with a Partial access state in a Flex Systems Manager 1.3.1 environment to achieve 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.
      Note: The same process can be followed for any IO module in the chassis, that includes FC5022 and EN4093R.
