ASM has the major number 188 while LVM device keeps 31. is that applicable to you?what does the `lifls` return for the ASM volume in your case?

Thank You SKT for replying back, cound not login to powerlink for at least a month ... EMC corporate taken the issue and the real issue was since this is an ASM cluster, the shutdown of Unix was not graceful, so EMC unmounted these disk and remounted after labelling, thing were fine.
