Creating the OSASM Group

You must designate a group as the OSASM group (asmadmin) during installation. Members of this group are granted the SYSASM system privileges to administer storage.

Create an OSASM group using the group name asmadmin unless a group with that name already exists: 
# groupadd -g 54323 asmadmin

The Oracle ASM instance is managed by a privileged role called SYSASM, which grants full access to Oracle ASM disk groups. Members of OSASM are granted the SYSASM role.
