This problem can occur on any platform.

Symptoms

Following the removal and re-creation of an ASM instance, you may see old data left behind from the old ASM instance.

ie

ls -l /dev/rdsk/osm*
-rw-rw-rwT 1 qatest g527 524288000 Jul 31 12:03 /dev/rdsk/osm1
-rw-rw-rwT 1 qatest g527 524288000 Jul 31 12:04 /dev/rdsk/osm2

You may also be unable to create an ASM diskgroup with the same name as an old diskgroup and may receive the following errors:

ORA-15018: diskgroup cannot be created
ORA-15033: disk '/dev/rdsk/osm2' belongs to diskgroup "DATA"
ORA-15033: disk '/dev/rdsk/osm1' belongs to diskgroup "DATA"
