适用场景

Data ONTAP 7 及更早版本

问题描述

如果 Data ONTAP 7 (此 AutoSupport 消息在 Data ONTAP 8 及更高版本中已降级)在 RAID 级别磁盘擦洗操作期间检测到任何问题,则会触发此 AutoSupport 消息。有关磁盘擦洗操作的问题描述 ,请参阅 RAID 级别磁盘擦洗如何验证数据完整性

在磁盘清理运行期间会检查许多情况、包括存储的奇偶校验、校验和和和磁盘介质错误。Data ONTAP 会在每个 RAID 组开始清理时记录一条消息、完成后、它会为每个 RAID 组记录一条摘要消息、其中包含清理持续时间和状态。如果您收到 DISK_SCRUB AutoSupport,则表示检测到错误,并且摘要消息详细说明了发现的任何错误

示例:

[raid.rg.scrub.start:notice]: /aggr0/plex0/rg0: starting scrub

...

[raid.rg.scrub.suspended:notice]: /aggr0/plex0/rg0: scrub suspended at stripe 16239552 after 2:07:11.32
[raid.rg.scrub.pi:error]: Inconsistent parity on RAID group /aggr0/plex0/rg0, stripe #16237976.
[raid.rg.scrub.pi:error]: Inconsistent parity on RAID group /aggr0/plex0/rg0, stripe #16237976.
[raid.rg.scrub.rewrite.data:notice]: Scrub fixing bad data on Disk /aggr0/plex0/rg0/0a.44 Shelf 2 Bay 12 [NETAPP DISK TYPE] S/N [SERIAL], block #16237976
[raid.rg.scrub.summary.pi:EMERGENCY]: Scrub found 2 parity inconsistencies in /aggr0/plex0/rg0.
[raid.rg.scrub.summary.cksum:notice]: Scrub found 0 checksum errors in /aggr0/plex0/rg0.
[raid.rg.scrub.summary.media:notice]: Scrub found 0 media errors in /aggr0/plex0/rg0.

在此示例 two parity inconsistency 中,擦洗在检测到错误后暂停。您可能还会看到有关checksum or media错误的消息。
