+Subject: [PATCH 1/1] manage: adjust checking subarray state in update_subarray
+
+Only changing bitmap related consistency_policy requires
+subarray to be inactive.
+consistency_policy with PPL or NO_PPL value can be changed on
+active subarray.
+It fixes regression introduced in commit
+db10eab68e652f141169 ("Fix --update-subarray on active volume")
