Issue

  • During an ONTAP upgrade of the cluster (ANDU), a node reboots unexpectedly:

page fault (supervisor read data, page not present) on VA 0xfffff681618fb000 cs:rip 0x20:0xffffffff8040ff8a rflags 0x10206 in SK process ctran_gm_0
  • This issue occurs on destination clusters of Consistency Group (CG) or FlexGroup volume SnapMirror relationships.
    • This includes asynchronous relationships with CGs or FlexGroup volumes and SnapMirror active sync (SMas) SAN relationships, since they replicate CGs.
  • This issue occurs while the destination cluster is in a mixed version state with ONTAP 9.16.1P10 or later 9.16.1 patch release and ONTAP 9.17.1 or later.
