+Subject: [PATCH] Add vector size check
+
+When PowerSupplyRedundancyEnabled is set to true and RotationRankOrder
+is 0, xyz.openbmc_project.coldredundancy.service core-dump issue
+is observed.
+
+Add a check to address above corner case and avoid core-dump.
+
+Tested:
+Verified core-dump is not observed with above settings
