问题描述

一个控制器崩溃，其中包括：

Panic String: aggr AGGR1: raid volfsm, fatal disk error in RAID group with no parity disk. raid type raid0 Group name plex0/rg2 state NORMAL 1 disk failed in the group. Disk SWXX1:11-38.206L17 Shelf - Bay - [NETAPP INF-01-00 0810] S/N [XXXXX] error no valid path to disk.

两个节点在 EMS 中报告类似事件：

Sat May 29 08:06:49 +0200 [node-02: slifc_asyncd_1: mlm.array.lun.PathRemoved:info]: Array LUN 'SWXX1:11-38.206L17' (XXXXX) is no longer available on initiator port 1a through array1's target port: WWNN: 200200a098xxxxxxx, WWPN: 201200a098xxxxxxx. Sat May 29 08:06:49 +0200 [node-02: slifc_asyncd_1: mlm.array.lun.OnePath:error]: Array LUN 'SWXX1:11-38.206L17' is connected using only one path. To avoid the potential for data loss caused by the remaining path's failure, all array LUNs should have at least two paths.
