Issue

  • Ethernet connect warnings are reported on NSM module:
[Node-01: dsa_worker0: ses.status.etherConn.warn:error]: NS224NSM100 (S/N SHFNCXXXX000047) shelf 10 on channel 0x Ethernet connector warning for port e0a: cannot communicate with connector.  This element is on the rear of the shelf at the top, on module A.
[Node-01: dsa_worker0: ses.status.etherConn.warn:error]: NS224NSM100 (S/N SHFNCXXXX000047) shelf 10 on channel 0x Ethernet connector warning for port e0b: cannot communicate with connector.  This element is on the rear of the shelf at the top, on module A.
  • The nodes lose path via one NSM module and following alert is reported in event logs:
[Node-01: nchmd: hm.alert.raised:alert]: Alert Id = NoPathToNSMA_Alert , Alerting Resource = 17438XXXXXXXXXXXXX raised by monitor node-connect
[Node-01: dsa_disc: shelf.config.tospha:info]: System has transitioned to single path HA attached storage
[Node-01: dsa_disc: callhome.dsk.redun.fault:error]: Call home for DISK REDUNDANCY FAILED
  • Amber LED is seen on the affected NSM module.
  • Nodes transition to single-path HA configuration:

::> system node run -node <node> sysconfig -a
