Answer

A single spare SSD owned by one node in an HA pair can function as a "global" spare if:

  1. AutoSupport section COREDUMP-STATUS.xml shows "Type of Core Dump" = "corefs"
  2. System must have the fix for bug 1361016

For other configurations a single non-partitioned SSD will not function as a global spare: automatically partition, change ownership, and be used to rebuild a degraded raid group.

Root-Data-Data configurations on models that do not show "Type of Core Dump" = "corefs" can be manually partitioned and assigned.  This will have to be done manually after each drive replacement and will result in no core available for analysis if a panic occurs.
