環境

  • ONTAP 9
  • MetroCluster IP
  • Broadcom BESBES-53248 スイッチ
  • Broadcom EFOS ファームウェア 3.4.4.4

問題

  • 影響を受ける MetroCluster サイトで電源が停止しています。 
  • ブートコンソールログに iSCSI session state is changed to Reconnecting for the targetエラーが記録されています。
例:
[ClusterB-01:iscsi.session.stateChanged:notice]: iSCSI session state is changed to Reconnecting for the target iqn.2016-06.com.netapp:09868cf1-034a-11e7-8ac6-d039ea1d28c3 (type: dr_partner, address: 192.168.188.1:65200). Reason: session login timed out.
[ClusterB-01:iscsi.session.stateChanged:notice]: iSCSI session state is changed to Reconnecting for the target iqn.2016-06.com.netapp:76acc4e4-034b-11e7-b81d-d039ea1d63df (type: dr_auxiliary, address: 192.168.188.2:65200). Reason: session login timed out.
  • ONTAP をパニック状態でブートできません

例:[ClusterB-02:cf.fm.noMBDisksOrIc:error]: Could not find the local mailbox disks. Could not determine the firmware state of the partner through the HA interconnect.
[ClusterB-02:mcc.config.bootConfigNotRead:ALERT]: Configuration could not be read from persistent storage due to internal error Failed to retrieve persistent storage (MBX) due to no mailbox disks being found. The system will try to retrieve or set the configuration automatically later, during boot.
PANIC  : Root volume is offline.

  • ONTAP を起動できても、リモートディスクが表示されないことがあります。

例:
Aggregate aggr0_CPJS_ClusterB_01 (online, raid_dp, mirror degraded, fast zeroed) (block checksums)
  Plex /aggr0_CPJS_ClusterB_01/plex0 (online, normal, active, pool0)
    RAID group /aggr0_CPJS_ClusterB_01/plex0/rg0 (normal, block checksums)

  Plex /aggr0_CPJS_ClusterB_01/plex6 (offline, failed, inactive)

  • T6 カードの 2 つのポートのステータス auto-unknown-fd-downはです。

例:

        e1a MAC Address:    00:07:43:5c:54:10 (auto-unknown-fd-down)
        e1b MAC Address:    00:07:43:5c:54:18 (auto-unknown-fd-down)

        Part Number:        110122960B0
        Hardware Revision:  0
        Serial Number:      PT20201067

  • T6 カードを交換しても問題が解決しない。
  • 2 つDown のスイッチポートのリンクステータスは、 ONTAP の T6 ポートに接続されているステータスです。
例:
