问题描述

由于同一 raidgroup 中存在多个故障磁盘或预故障磁盘， ONTAP 会生成以下警报

HA Group Notification (RAID DETECTED UNRECOVERABLE ERRORS) CRITCAL

[Cluster1: config_thread: callhome.raid.no.recover:EMERGENCY]: Call home for RAID DETECTED UNRECOVERABLE ERRORS

在中 sysconfig -r ，我们可以看到双重建和故障前驱动器

cluster::> node run -node Node-01 -command sysconfig -r

RAID group /Aggr_1/plex0/rg2 (double reconstruction 0% completed, block checksums)
