問題

  • ノードNode-01で、パス2b経由で異なるディスクドライブに対して次の「scsi.cmd.abortedByHost」イベントが表示されます。
Thu Mar 20 16:35:06 +0100 [Node-01: slifc_intrd: scsi.cmd.abortedByHost:error]: Disk device 2b.125L62: Command aborted by host adapter: HA status 0x4: cdb 0xea:0bbc6000:01e0.

  • ノードNode-01のFCポート2Dは頻繁にフラッピングしており、その理由としてStorageFCAdapterFault_Alertが報告されています。
Thu Mar 20 16:36:29 +0100 [Node-01: slifc_asyncd_4: fci.adapter.link.online:info]: Fibre Channel adapter 2b link online.
Thu Mar 20 16:37:10 +0100 [Node-01: slifc_timeout_4: fci.link.error:error]: Could not recover link on Fibre Channel adapter 2b after 30 seconds. Taking the adapter offline.
Thu Mar 20 16:37:10 +0100 [Node-01: dsbridge_admin: bridge.removed:info]: FC-to-SAS bridge 2b.125L0 [ATTO   FibreBridge7600N 4.35] S/N [FB7600N106192] was removed.
Thu Mar 20 16:37:20 +0100 [Node-01: nchmd: hm.alert.raised:alert]: Alert Id = StorageFCAdapterFault_Alert , Alerting Resource = 100000109b4ede02 raised by monitor node-connect

Thu Mar 20 16:51:27 +0100 [Node-01: dsbridge_admin: bridge.discovered:info]: FC-to-SAS bridge 2b.125L0 [ATTO   FibreBridge7600N 4.35] S/N [FB7600N106192] was discovered.
 
  • FCポート2bが停止すると、ATTOブリッジFB7600N106192へのアクセスが失われたためノードが混在パス構成に移行しており、次のイベントが報告されます。
Thu Mar 20 16:48:44 +0100 [Node-01: svc_queue_thread: callhome.dsk.redun.fault:error]: Call home for DISK REDUNDANCY FAILED
Thu Mar 20 16:49:24 +0100 [Node-01: dsa_disc: ses.multipath.ReqError:alert]: SAS disk shelf detected without a multipath configuration.
