使用后端阵列的 MetroCluster 出现丛故障
适用于
- MetroCluster
- FlexArrray
- ONTAP 9
问题
- 连接到 ONTAP Fabric MetroCluster 的存储阵列报告由于 SCSI 超时错误而导致多个磁盘失败：
示例：
Fri Dec 04 20:09:18 EST [node1: config_thread: raid.config.filesystem.disk.not.responding:notice]: File system Disk /node1/plex0/rg0/switch1:12.126L119 Shelf - Bay - [NETAPP INF-01-00 0842] S/N [xxxxxxxxxxxxxxxxxxxxxx] UID [xxxxxxxx:xxxxxxxx:xxxxxxxx:xxxxxxxx:00000000:00000000:00000000:00000000:00000000:00000000] is not responding.
- 这些错误会导致 MetroCluster 中的两个集群出现多个 syncmirror 丛故障。
示例：
Aggregate aggrname (online, raid0, mirror degraded) (block checksums)
Plex /aggrname/plex0 (offline, failed, inactive)
RAID group /aggrname/plex0/rg0 (partial, block checksums)
RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks)
