# ==== Purpose ====
#
# Assert SPM consistency for ONLINE and RECOVERING members.
# Confirms all members have:
# 1. SPM mode set,
# 2. Enforce_update_everywhere_checks is not set,
# 3. Have same primary,
# 4. Super read-only set if secondary else not set
# 5. ONLINE and RECOVERING numbers are same in each member
# 6. No member in ERROR state.
#
# ==== Usage ====
#
#   [--let $_primary_member_of_group=server_uuid]
#   --source include/gr_assert_spm_consistency.inc
#
# Parameters:
#   $_primary_member_of_group
#     Server UUID of primary member of the group.
