+ $0 manages a Oracle ASM Disk Group through Oracle GI commands
+ The 'start' operation starts the diskgroup, or waits for the ASM DG to become available
+ The 'stop' operation stops the ASM diskgroup
+ The 'status' operation reports whether the ASM diskgroup is active
+ The 'monitor' operation is similar to status
+ The 'validate-all' operation reports whether the parameters are valid
