Solution 2029678.1 : Oracle ZFS Storage Appliance: How to determine which connector is assigned to which UART on a 7420 or ZS3-4 Clustron card

Applies to:

Sun ZFS Storage 7420 - Version All Versions to All Versions [Release All Releases]
Oracle ZFS Storage ZS3-4 - Version All Versions to All Versions [Release All Releases]
7000 Appliance OS (Fishworks)

Goal

To identify which port on a Clustron card is associated with which UART and Ethernet port

NOTE: To confirm that the cluster 'links' cabling is correctly configured - See Document ID 2081179.1

Solution

There are 2 UART connections and one Ethernet connection on a Clustron card.

This is an example of the 'normal' status:

NAS:> configuration cluster links

        clustron2:0/clustron_uart:0 = AKCIOS_ACTIVE
        clustron2:0/clustron_uart:1 = AKCIOS_ACTIVE
        clustron2:0/dlpi:0 = AKCIOS_ACTIVE

If one sees something different than that such as the following, then it could indicate that a cable is not plugged in fully or is bad.

NAS:> configuration cluster links

        clustron2:0/clustron_uart:0 = AKCIOS_ACTIVE
        clustron2:0/clustron_uart:1 = AKCIOS_TIMEDOUT
        clustron2:0/dlpi:0 = AKCIOS_ACTIVE

Each Clustron port has an indicator that is either Green (OK) or Amber (not OK).

The Clustron connections on a 7420 or ZS3-4 are:

Top: uart:1

Middle; ethernet (dlpi)

Bottom: uart:0
