問題

NetAppコントローラがすべてのメッセージまたは特定のメッセージの送信に失敗しています。この場合、failed diskメッセージの送信に失敗していました。

Autosupoprt履歴の確認

Cluster::>autosupport history show

Seq Attempt Percent Last Node Num Destination Status Count Complete Update ------------ ----- ----------- -------------------- -------- -------- -------- node01 1680 http transmission-failed 15 - 5/28/2020 02:20:53

「system autosupport history show -seq-num ### -instance 」コマンドを使用して特定のシーケンスを確認し、Last Error がUnknown error であることを確認します。

Cluster::> system autosupport history show -seq-num 1680 -instance

Node: node01 AutoSupport Sequence Number: 1680 Destination for This AutoSupport: http Trigger Event: callhome.sdsk.fault Time of Last Update: 5/28/2020 02:20:53 Status of Delivery: transmission-failed Delivery Attempts: 15 AutoSupport Subject: SPARE DISK FAILED Shelf 0, Bay 0, Model [X357_S16433T8ATE] Delivery URI: support.netapp.com/put/AsupPut/ Last Error: Unknown error Time of Generation: 5/28/2020 00:01:51 AutoSupport Compressed Size: 131.4KB Percent Complete: - Rate of Upload: - Time Remaining for Upload: 0s AutoSupport Decompressed Size: 476.0KB Total Collection Time (ms): 6257

詳細なエラーメッセージは、notifyd.log によってAutoSupportサブシステムに記録されたエラーを /mroot/etc/log/mlog/notifyd.logで確認することで確認できます。

notifyd.logの確認方法
