ONTAP 9

Issue

  • During an Ontap Upgrade, one node upgrades the Ontap version, but fails to boot to continue with the takeover/giveback

Cluster::*> cluster image show
Node                 Current Version         Installation Date
-------------------- ----------------------- -------------------
Node-01          9.16.1P6                   xx/xx/xxxx 21:24:12
Node-02          9.16.1P11                xx/xx/xxxx 16:43:20

  • Checking Storage Failover Show we can see interconnect issues:


Cluster::> sto fail show
(storage failover show)
Node           Partner        Possible State Description
-------------- -------------- -------- -------------------------------------
Node-01    Node-02    false    Waiting for Node-02, Takeover is
                                                               not possible: Storage failover
                                                               interconnect error, NVRAM log not
                                                               synchronized, Disk inventory not
                                                               exchanged
Node-02    Node-01    false    Waiting for Node-01, Takeover is
                                                               not possible: Storage failover
                                                               interconnect error, NVRAM log not
                                                               synchronized, Disk inventory not
                                                               exchanged

  • And when we check on the interconnect status we see that the links are up but the RDMA is down

Cluster::*> ha interconnect status show
(system ha interconnect status show)
Node: Node-01
Link 0 Status: up
Link 1 Status: up
Is Link 0 Active: true
Is Link 1 Active: true
IC RDMA Connection: down

Node: Node-02
Link 0 Status: up
Link 1 Status: up
Is Link 0 Active: true
Is Link 1 Active: true
IC RDMA Connection: down
