Solution 2017725.1 : Oracle ZFS Storage Appliance: After upgrade to 2013.1.2.0 (or later), the underlying IP interfaces of IPMP groups do not appear under 'Cluster Resources'

Applies to:

Sun Storage 7410 Unified Storage System - Version All Versions and later
Sun Storage 7310 Unified Storage System - Version All Versions and later
Oracle ZFS Storage ZS3-4 - Version All Versions and later
Oracle ZFS Storage ZS3-2 - Version All Versions and later
Oracle ZFS Storage ZS4-4 - Version All Versions and later
7000 Appliance OS (Fishworks)

Symptoms

A customer upgraded the Appliance Firmware Release version from 2013.1.1.6 to 2013.1.3.0.

After the upgrade, the cluster resources screen no longer sees the 'component' network interfaces for an IPMP group.

Before upgrade:

NAS_01:> configuration cluster resources show
Resources:

RESOURCE       OWNER    TYPE   LABEL     CHANGES DETAILS
net/igb0       NAS_01   private NET0      no       101.1.130.53
net/ipmp1      NAS_01 singleton IB_IPMP1 no       192.168.204.31,192.168.204.32
net/pffff_ibp0 NAS_01 singleton IB0       no
net/pffff_ibp2 NAS_01 singleton IB2       no
zfs/pool-01    NAS_01 singleton          no       578T
zfs/pool-02    NAS_01 singleton        no       339T

After upgrade:

NAS_02:> configuration cluster resources show
Resources:

RESOURCE    OWNER    TYPE   LABEL     CHANGES DETAILS
net/igb1    NAS_01   private NET1      no       101.1.130.55
net/ipmp1   NAS_01 singleton IB_IPMP1 no       192.168.204.31,192.168.204.32
zfs/pool-01 NAS_01 singleton          no       578T
zfs/pool-02 NAS_01 singleton          no       339T

NOTE: 'ibp0' and 'ibp2' are no longer visible.

Cause

This issue is related to the following two CRs (both are closed as "Not a Bug"):

19951901 - Private IPMP interfaces design in AK8 is inadequate
19049600 - Unable to set type to private on ipmp interface with version AK 2013.1.2

Solution

From Bug ID 19049600:

Private Local IP Interfaces
-----------------------------
Use the following guidelines when creating private local IP interfaces:

Creating an IP interface with the same name as a private IP interface on cluster peer, results in the local creation of a private IP interface.

Datalinks in use by the peer's private interfaces can not be deleted and the delete button is greyed out.

IP interfaces that belong to an IPMP group must all be of the same type and belong to the same head. To create an IPMP group you must use either all singleton or all private IP interfaces and your cluster node must be the owner of these interfaces.

The IPMP group type is set only at creation, and is determined by the type of underlying links.

IP interfaces that belong to IPMP groups do not appear on the Cluster:Resources page because IP interface ownership cannot be modified independently of the IPMP group ownership.

Private IPMP groups do not appear in the Cluster:Resources page because this type or ownership cannot be modified.

=> So, this is a 'design' change.
