  • ファブリック接続MetroCluster

問題

  • イベントログで呼び出されたアダプタを介してすべてのノードで1つのATTOブリッジへのパスが欠落しています。

[Node-102: isp2400_timeout_0: fci.device.quiesce:debug]: Adapter 1d encountered a command timeout on Unknown device Switch1:10.126 (0x00080a00) LUN 0 cdb 0x12 retry: 0 Quiescing the device.
[Node-102: isp2400_asyncd_0: fci.device.login.status:debug]: A login delay has occurred between Fibre Channel adapter 1d and unknown device Switch1:10.126 (0x00080a00), with error subcode 0x703.

[Node-101: svc_queue_thread: callhome.dsk.redun.fault:error]: Call home for DISK REDUNDANCY FAILED

  • すべてのノードが「クアッドパスHA」構成から「マルチパスHA」構成に移行します。

[Node-101: dsa_disc: shelf.config.tompha:info]: System has transitioned to multi-path HA attached storage

  • 該当するATTOブリッジのFCポートで複数のエラーが報告されます。
