# Troubleshooting interconnects

- Interconnect edit is unsuccessful

- Interconnect modules are in an incorrect state

- Replace an Virtual Connect interconnect in a managed enclosure

## Interconnect edit is unsuccessful

Symptom | Possible cause and recommendation
--- | ---
Notification that modifying an interconnect was unsuccessful | If interconnect edit is unsuccessful: Verify that the prerequisites listed in Procedure: Enabling or disabling an uplink port or downlink port on an interconnect are met. Follow the instructions provided by any notification message. When the interconnect has been edited successfully, a notification will display in the banner at the top of the screen, and the desired port setting and port status will be displayed.

## Interconnect modules are in an incorrect state

Symptom | Possible cause and recommendation
--- | ---
Interconnect module is in an Inventory state | The interconnect module is not part of a logical interconnect. To bring the interconnect module into a managed or monitored state: Locate or create the logical interconnect group for the enclosure using the Logical Interconnect Groups screen. From the main menu, select Enclosure Groups. Edit the enclosure group and add the logical interconnect group from step 1. From the main menu, select Logical Enclosures and update the logical enclosure configuration from the enclosure group.
Interconnect modules are in a Maintenance state | There is an OA credential caching issue if interconnect modules report their state as `Maintenance`. If interconnect modules are in a Maintenance state: You have to re-add the enclosure. From the main menu, select Enclosures→Add. Provide the enclosure information (IP/FQDN, Administrator account and password), and click the Add button. This will initiate rediscovery of the enclosure and its components.
Interconnect modules are in an Unmanaged state | Interconnect bay has a mismatch with the expected type The logical interconnect group is expecting a different interconnect than what is in the enclosure. Remove the unexpected interconnect from the enclosure Insert the expected interconnect into the enclosure. Use the interconnect by updating the logical interconnect group.
Interconnect has firmware installed which is less than the minimum supported baseline version For an Virtual Connect Fibre Channel interconnect: The enclosure contains an Virtual Connect Fibre Channel interconnect with IPv6 addresses and the interconnect firmware version is less than 4.10, the minimum supported baseline version. The enclosure contains only an Virtual Connect Fibre Channel interconnect by itself or with other Virtual Connect Fibre Channel interconnects and the interconnect firmware version is less than 4.10, the minimum supported baseline version. Recommendation If the interconnect firmware version is at or above the minimum to import (v3.15), you can update to the supported version after adding the interconnect. If interconnect firmware is below version 3.15, then follow these steps: Remove the enclosure. Update the firmware for HPE Virtual Connect interconnects configured for Fibre Channel networks. Add the enclosure to manage its contents. For an interconnect that is not an Virtual Connect Fibre Channel, update the interconnect firmware for the logical interconnect. See the HPE OneView Support Matrix for the complete list of supported firmware versions.

## Replace an Virtual Connect interconnect in a managed enclosure

Symptom | Possible cause and recommendation
--- | ---
Interconnect status is `Missing` or `Incompatible` | Interconnect module was in use when it was removed from an enclosure If a Virtual Connect Fibre Channel module was in use and configured at the time it was physically removed, it must be replaced by a module of the same model and type. A Virtual Connect Fibre Channel module is in use if any of the following conditions exist: Interconnect module is in an interconnect bay using a Virtual Connect release earlier than the minimum supported version The networks associated with the uplink ports on the interconnect module are being used by a server profile
5. Interconnect failure | Interconnect failed and must be replaced Unplug all interconnect cables and remove the interconnect from the enclosure. Insert the replacement interconnect, and then re-plug in all interconnect cables. Log into the appliance. From the main menu, select Logical Interconnects, and then select the logical interconnect that contains the replaced interconnect From the view menu, select Activity. An activity for the added interconnect appears in the activity list. If the interconnect firmware version is the same or greater than the supported minimum firmware version, the appliance automatically applies the logical interconnect group to the replaced interconnect and the interconnect is ready to use. If the interconnect firmware is less than the supported minimum firmware baseline, an alert is generated and you must update the firmware as shown in step 6.
   | NOTE: To view the installed firmware, select Firmware from the view selector.
6. Update the firmware on the interconnects. For Fibre Channel interconnects, see below. For FlexFabric interconnects, go to step 7.
   | NOTE: Fibre Channel interconnects with a firmware version that is below the HPE OneView minimum version cannot be managed by HPE OneView. You must remove the enclosure to update or delete the firmware outside of HPE OneView. If the Fibre Channel interconnects are below the minimum version, remove the enclosure from HPE OneView and update the Fibre Channel interconnects to the minimum version. Alternatively, remove the interconnects from the HPE OneView managed enclosure and insert into an enclosure which is not managed by HPE OneView and update the firmware to the minimum version. The minimum version requirements are listed in the HPE OneView Support Matrix.
Either remove the enclosure from HPE OneView or physically remove the Fibre Channel interconnects and place them into an enclosure that is not currently being managed by HPE OneView. Use the Onboard Administrator or the external DHCP server to assign an IPv4 address to the interconnect. Use HP SUM or the Virtual Connect Support Utility (VCSU) to update the firmware on the interconnect. Add the enclosure to HPE OneView or return the Fibre Channel interconnects to an HPE OneView-managed enclosure. Optional: If the Fibre Channel interconnects are intended to support an IPv6 address, use the Onboard Administrator or an external DHCP server to assign an IPv6 address to the interconnect. See “Update a firmware bundle on managed devices“ in the online help for firmware update information. Firmware update progress will be shown at the top of the Logical Interconnects screen. When the upgrade is finished, the appliance automatically applies the Logical interconnect group and the interconnect is ready to use.
