none :- Prints the PATH column of the V$ASM_DISK_STAT view.
-k :- Prints the TOTAL_MB, FREE_MB, OS_MB,NAME, FAILGROUP, LIBRARY, LABEL, UDID, PRODUCT, REDUNDANCY, and PATH columns of the V$ASM_DISK view.
--statistics :- Prints the READS, WRITES, READ_ERRS, WRITE_ERRS, READ_TIME, WRITE_TIME, BYTES_READ, BYTES_WRITTEN, and the PATH columns of the V$ASM_DISK view.
-p :- Displays the GROUP_NUMBER, DISK_NUMBER, INCARNATION, MOUNT_STATUS, HEADER_STATUS, MODE_STATUS, STATE, and the PATH columns of the V$ASM_DISK view.
-t :- Displays the CREATE_DATE, MOUNT_DATE, REPAIR_TIMER, and the PATH columns of the V$ASM_DISK view.
-g :- Selects from GV$ASM_DISK_STAT, or from GV$ASM_DISK if the --discovery flag is also specified.
--discovery :- Selects from V$ASM_DISK, or from GV$ASM_DISK if the -g flag is also specified.
--suppressheader :- Suppresses column headings.
-I :- Scans disk headers for information rather than extracting the information from an Oracle ASM instance.
-G :- Restricts results to only those disks that belong to the group specified by disk group.
-M :- Displays the disks that are visible to some but not all active instances. These are disks that, if included in a disk group, cause the mount of that disk group to fail on the instances where the disks are not visible.
--candidate :- Prints the disk devices whose status is CANDIDATE.
--member :- Prints the disk devices whose status is MEMBER.
pattern :- Returns only information about the specified disks that match the supplied pattern.
