Plan of Action

  • Asked customer to send the latest SP logs for analysis.
  • Once received the logs from customer we started analyzing the Logs.
  • Found SPS A showing faulty & SPS B cabling unknown state.
  • Physically verified the storage and identifying the failed SPS by Amber notification
  • SPS B:  (1.2KW) OK but showing Unknown Configuration State.

Solution: – Need to Replace SPS A

After Replacing SPS A, Customer found that the EMC storage resulted in slow performance, and we had a discussion with the customer & asked him to share the latest SP logs after replacing the SPS A Power Supply. We found that the SPS LED glowed Green as per the Onsite Engineer and once we analyzed the sent Logs & found both SPS cabling showing unknown State & Write Cache Disabled.

Scenario: – Enclosure SPE SPS A Cabling State: Cabling Status is unknown

Enclosure SPE SPS B Cabling State: Cabling Status is unknown

Error: – Write Cache Disabled

This issue has been addressed in the initial release of FLARE OS, it is required to Reboot the SPS on the error reporting side & before restarting the SPS, need to check LUN trespassed, multipathing, Host connectivity & any HDD predictive failure.

Taken the remote session from customer & checked the storage, found 4 path connected on host, some LUN connected to Celerra NAS storage this LUN not confirm Multipath, asked to customer we required only SPS restarts & IOPS stop.
