actually when the issue was happened , DBA team logged a case to oracle about disk group. After few minute's they asked to run some script(containing something kfed commands) and asked to upload the o/p. After observing the o/p directly they told that dm-32 owner need to be changed to root:disk. And after changing the owner , issue got resolved.
