md_backup
The md_backup command creates a backup file containing metadata
for one or more disk groups.
Volume and Oracle Automatic Storage Management Cluster File System
(Oracle ACFS) file system information is not backed up.
md_backup backup_file [-G diskgroup [,diskgroup,...]]
The options for the md_backup command are described below.
backup_file - Specifies the backup file in which you want to
store the metadata.
-G diskgroup - Specifies the disk group name of the disk group
that must be backed up
By default all the mounted disk groups are included in the backup file,
which is saved in the current working directory.
The first example shows the use of the backup command when you run it
without the disk group option. This example backs up all of the mounted
disk groups and creates the backup image in the current working
directory. The second example creates a backup of disk group DATA and
FRA. The backup that this example creates is saved in the
/tmp/dgbackup20090716 file.

7，asmcmd help lsdsk顯示ASM磁碟
[grid@zxy ~]$
[grid@zxy ~]$ asmcmd help lsdsk
lsdsk
List Oracle ASM disks.
lsdsk [-kptgMI][-G diskgroup ] [--suppressheader] [ --member|--candidate] [--discovery][--statistics][pattern]
The options for the lsdsk command are described below.
(none) - Displays the PATH column of the V$ASM_DISK_STAT view.
-k - Displays the TOTAL_MB, FREE_MB, OS_MB,NAME, FAILGROUP,
LIBRARY, LABEL, UDID, PRODUCT, REDUNDANCY, and PATH
columns of the V$ASM_DISK view.
--statistics - Displays 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$ASM_DISK if
the --discovery flag is also specified.
GV$ASM_DISK.INST_ID is included in the output.
--discovery - Selects from V$ASM_DISK, or from GV$ASM_DISK
if the -g flag is also specified. This option is always
enabled if the Oracle ASM instance is version 10.1 or
earlier. This flag is disregarded if lsdsk is running
in non-connected mode.
-I - Scans disk headers for information rather than
extracting the information from an Oracle ASM instance.
This option forces non-connected mode.
-G - Restricts results to only those disks that belong to
the group specified by diskgroup.
-M - Displays the disks that are visible to some but not
all active instances. These are disks that, if included
in a disk group, will cause the mount of that disk group
to fail on the instances where the disks are not visible.
--suppressheader - Suppresses column headings.
--candidate - Restricts results to only disks having
membership status equal to CANDIDATE.
--member - Restricts results to only disks having membership
status equal to MEMBER.
pattern - Returns only information about the specified disks
that match the supplied pattern.
The lsdsk command can run in connected or non-connected mode.
The connected mode is always attempted first. The -I option
forces non-connected mode.
In connected mode, lsdsk uses the V$ASM_DISK_STAT and V$ASM_DISK
dynamic views to retrieve disk information. The V$ASM_DISK_STAT
view is used by default.
In non-connected mode, lsdsk scans disk headers to retrieve
disk information. Some information is not available in this
mode and some options are not valid combinations with this mode.
Note: The non-connected mode is not supported on Microsoft Windows.
pattern restricts the output to only disks that match the pattern
specified. Wild-card characters and slashes (/ or \) can be part
of the pattern. pattern should be specified as the last option for
the command.
The -k, -p, -t, and --statistics options modify how much information
is displayed for each disk. If any combination of the options are
specified, then the output shows the union of the attributes
associated with each flag.
The following are examples of the lsdsk command. The first and second
examples list information about disks in the DATA disk group. The third
example lists information about candidate disks.
