适用场景

  • MetroCluster IP (MCC IP)
  • ONTAP 9

问题描述

  • mcc_A-02出现故障、需要更换MB。只有MCC A-01处于联机状态并接管了 MCC A-02
  • MetroCluster强制切换可使用命令执行metrocluster switchover -forced-on-disaster true -override-vetoes true
  •  由于强制切换操作、由MCC B触发的节点MCC A-01关闭
  • 切换完成后、 集群 MCC A的数据聚合 将 状态报告为"失败、RAID-DP、过期"
  • plex0将状态显示为"脱 机、失败、非活动"
  • plex1会将状态显示为"Offline、Normal、O过时"
例如:
MCC_B-01> aggr status -r MCC_A-01_aggr1
Aggregate MCC_A-01_aggr1 (failed, raid_dp, out-of-date) (block checksums)
Plex /MCC_A-01_aggr1/plex0 (offline, failed, inactive)
 
Plex /MCC_A-01_aggr1/plex1 (offline, normal, out-of-date)
RAID group /MCC_A-01_aggr1/plex1/rg0 (normal, block checksums)
RAID Disk Device HA  SHELF BAY CHAN Pool Type  RPM  Used (MB/blks)   Phys (MB/blks)
