Applies to

  • MetroCluster IP
  • ONTAP 9.5 and later
  • MetroCluster Installation
  • HA connectivity on MetroCluster IP (IC RDMA)

Issue

  • While configuring a MetroCluster IP, the HA interconnect does not come online after booting the nodes and configuring the cluster.

ClusterA::> cluster ha show
High Availability Configured: false

Warning: Cluster HA has not been configured.  Cluster HA must be configured
         on a two-node cluster to ensure data access availability in the
         event of storage failover. Use the "cluster ha modify -configured
         true" command to configure cluster HA.


ClusterA::> storage failover show
                              Takeover
Node           Partner        Possible State Description
-------------- -------------- -------- -------------------------------------
ClusterA-01   -              false    Waiting for partner, Takeover is not
                                       possible: Storage failover is
                                       disabled
ClusterA-02   -              false    Waiting for partner, Takeover is not
                                       possible: Storage failover is
                                       disabled
2 entries were displayed.

  • During boot, the following messages might be seen:

mccip_install_dr_ips: bootarg.ic_local_ip not set, bailing
iw_cxgbe: Chelsio T4/T5/T6 RDMA driver loaded

[cluster_A-01:cf.fsm.takeoverOfPartnerDisabled:error]: Failover monitor: takeover of ClusterA-02 disabled (HA interconnect error. Verify that the partner node is running and that the HA interconnect cabling is correct, if applicable. For further assistance, contact technical support).

  • Interfaces will report as down:

ClusterA::> run local sysconfig -v 5
        slot 5: Dual 40/100G Ethernet T62100-CR
                e5a MAC Address:    00:07:43:3e:cf:50 (auto-unknown-fd-down)
                e5b MAC Address:    00:07:43:3e:cf:58 (auto-unknown-fd-down)
                Device Type:        T6 2
                Firmware Version:   1.23.0.0
                Part Number:        110122860A0
                Hardware Revision:  0
                Serial Number:      PT28170188

  • High Availibility interconnect can not be activated:
ClusterA::> cluster ha modify -configured true
Warning: High Availability (HA) configuration for cluster
services requires
         that both SFO storage failover and SFO auto-giveback be enabled. These
         actions will be
performed if necessary.
Do you want to continue? {y|n}: y
Error: command failed: Could not retrieve partner SFO information: entry doesn't exist.
  • Connected switch ports are down with status Link not connected
