  • E2824
  • SANtricity OS 11.50R1
  • Asynchronous Remote Volume Mirroring (ARVM)

Issue

  • After regular ISL maintenance, sometimes asynchronous mirroring replication gets stuck and cannot resume automatically.
  • When mirroring gets stuck:
    • Port 0f from Controller A or B is unknown in communication test from the primary array.
    • Communication test from the secondary array passes without issue.
