安装MetroCluster IP期间HA互连关闭

适用场景

• MetroCluster IP
• ONTAP 9.5及更高版本
• MetroCluster安装
• 基于MetroCluster IP的HA连接(IC RDMA)

问题描述

• 配置MetroCluster IP时、HA互连在启动节点并配置集群后不会联机。

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

• 在启动期间、可能会显示以下消息：

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).

• 接口将报告为已关闭：

• 无法激活高可用性互连：

 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. 

• 连接的交换机端口已关闭并显示状态 Link not connected
