问题描述

EMS日志警报：

[Node-01: disk_admin: multi.dsk.cksum.err:EMERGENCY]: Checksum verification failures reported by multiple disks connected to adapter 0n. [Node-01: disk_admin: callhome.multi.dsk.cksum.err:EMERGENCY]: Call home for Write Verification Error: Port 0n

将磁盘添加到聚合后会出现这些警报

[Node-01: config_thread: raid.vol.disk.add.done:notice]: Addition of Disk /Aggr1/plex0/rg0/0n.2P1 Shelf 0 Bay 2 [NETAPP X4010S17331T9NTE NA53] S/N [XXXXXXXXXXXXXXXXXXX] UID [66305030:54601066:00253841:00000002:500A0981:00000001:00000000:00000000:00000000:00000000] to aggregate Aggr1 has completed successfully [Node-01: config_thread: raid.vol.disk.add.done:notice]: Addition of Disk /Aggr1/plex0/rg0/0n.1P1 Shelf 0 Bay 1 [NETAPP X4010S17331T9NTE NA53] S/N [XXXXXXXXXXXXXXXXXXX] UID [66305030:54601063:00253841:00000002:500A0981:00000001:00000000:00000000:00000000:00000000] to aggregate Aggr1 has completed successfully [Node-01: config_thread: raid.vol.disk.add.done:notice]: Addition of Disk /Aggr1/plex0/rg0/0n.0P1 Shelf 0 Bay 0 [NETAPP X4010S17331T9NTE NA53] S/N [XXXXXXXXXXXXXXXXXXX] UID [66305030:54601065:00253841:00000002:500A0981:00000001:00000000:00000000:00000000:00000000] to aggregate Aggr1 has completed successfully

然后在磁盘上观察到RAID错误

raid_multierr_cksum_bno_1:notice raid_multierr_bad_block_1:error raid_tetris_cksum_bno_1:notice
