Issue

  • Following a insertion or removal of a motherboard from the chassis, the partner node may experience a loss of visibility to one or more drives on the internal chassis.
    • The node may experience a multi-disk panic due to the loss of multiple drives in the same RAID group.
  • This issue does not impact disks on external shelves.
  • This issue may create WAFL inconsistencies messages like:

[node_name: wafl_exempt17: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 0123456789 (...) in volume volume_name@vserver:...

  • The following messages may be observed in EMS:
