Issue

On node Node-01, the following "scsi.cmd.abortedByHost" events are seen for different disk drives via path 2b

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.

Thu Mar 20 16:35:09 +0100 [Node-01: slifc_intrd: scsi.cmd.abortedByHost:error]: Disk device 2b.125L55: Command aborted by host adapter: HA status 0x4: cdb 0x2a:8bb9edf8:0008.

FC port 2d of node Node-01 is flapping very frequently and StorageFCAdapterFault_Alert is reported due to that:

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 16:51:11 +0100 [Node-01: slifc_asyncd_4: fci.adapter.online:info]: Fibre Channel adapter 2b is now online.

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.

When FC port 2b is down, the access to ATTO bridge FB7600N106192 was lost and hence the node was transitioning to Mixed-Path configuration and the following events are reported:

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.

Thu Mar 20 16:50:03 +0100 [Node-01: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process nchm: SinglePathToDiskShelf_Alert[2937244207926544976].
