remove asm disk when header_status = 'MEMBER'?

user13487552Sep 29 2014 — edited Oct 16 2014

Hi, I'm working with 11.2 rdbms and asm on AIX 6.1. The administrator who managed this asm instance has retired. We're doing some work on the SAN and I'd like to remove two hdisks because they are unused (hdisk12 and hdisk29) and too small (1 GB) and they don't seem to belong to any disk group but they still show as members (I guess to Group zero). Can I safely remove these disks from ASM? How should that be done?
