7000 Appliance OS (Fishworks)

Symptoms

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

The cluster will not join as both nodes have the same ASN in the root disks

On trying to join the the joining cluster will state:

'cabling is not correct or peer is faulty'

Both heads can be configured to work with dummy values and each will work fine as singletons

Cause

It has been noted from the shipping information that the root disks have been moved between the two heads

This meant that both heads having the same ASN & CSN

Solution

A factory reset or altering the CSN did not cure this.

The only option was to reinstall the head using a fishstick on the head that had a different CSN than the one on the SP/ILOM

The clue came about when each head was dummy configured, they both had the same serial number in the support bundle.

NOTE: Do not move system/boot disks between NAS heads as once the OS is on the CSN and ASN are populated throughout the configuration files.
