問題

  • ONTAP には、障害が発生したディスクや事前に障害が発生したディスクが同じ raidgroup に複数含まれているため、次のアラートが生成されます
HA Group Notification (RAID DETECTED UNRECOVERABLE ERRORS) CRITCAL
[Cluster1: config_thread: callhome.raid.no.recover:EMERGENCY]: Call home for RAID DETECTED UNRECOVERABLE ERRORS
  • sysconfig -r は、二重再構築と障害発生前のドライブが使用されています
cluster::> node run -node Node-01 -command sysconfig -r
