  • E 系列后端

问题

  • 客户在 E 系列存储阵列上执行固件更新时,连接的 ONTAP Fabric MetroCluster 报告多个磁盘因 SCSI 超时错误而出现故障:
 
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)
