dsget 获取diskstring的值，参数不同，取值的地方也不一样
Retrieves the discovery diskstring value that is
used by the Oracle ASM Instance and its clients
dsget [[--normal] [--profile [-f]] [--parameter]]
The options for the dsget command are described below.
--normal - Retrieves the discovery string from the Grid Plug
and Play (GPnP) profile and the one that is set in
the Oracle ASM instance. It returns one row each for
the profile and parameter setting. This is the
default setting.
--profile [-f] - Retrieves the discovery string from the GPnP
profile. If -f is specified, retrieves the
discovery string from the local GPnP profile.
--parameter - Retrieves the ASM_DISKSTRING parameter setting of
the Oracle ASM instance.
ASMCMD> dsget --normal
parameter:/dev/oracleasm/disks*
profile:/dev/oracleasm/disks*
ASMCMD> dsget --profile
profile:/dev/oracleasm/disks*
ASMCMD> dsget --parameter
parameter:/dev/oracleasm/disks*
ASMCMD>
dsset 设置diskstring的值，参数不同，设置的范围也不同
Sets the discovery diskstring value that is used by the Oracle ASM
instance and its clients. The specified diskstring must be valid for
existing mounted disk groups. The updated value takes effect
immediately.
dsset [--normal] [--parameter] [--profile [-f]] diskstring
The options for the dsget command are described below.
--normal - Sets the discovery string in the Grid Plug
and Play (GPnP) profile and in the Oracle
ASM instance. The update occurs after the
Oracle ASM instance has successfully
validated that the specified discovery
string has discovered all the necessary disk
groups and voting files. Note that this
command fails if the instance is not using
a server parameter file (SPFILE). This is
the default setting.
--profile [-f] - Specifies the discovery diskstring that is
pushed to the GPnP profile without any
validation by the Oracle ASM instance,
ensuring that the instance can discover
all the required disk groups. The update
is guaranteed to be propagated to all the
nodes that are part of the cluster
If -f is specified, the specified
diskstring is pushed to the local GPnP
profile without any synchronization with
other nodes in the cluster. Note that this
command option updates only the local profile
file. This option should only be used in the
case of recovery. The command fails if the
Oracle Clusterware stack is running.
--parameter - Specifies that the diskstring is updated in
memory after validating that the discovery
diskstring discovers all the current mounted
disk groups and voting files. The diskstring
is not persistently recorded in either the
SPFILE or the GPnP profile.
diskstring - Specifies the value for the discovery
diskstring
ASMCMD> dsset --normal /dev/oracleasm
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-15014: path '/dev/oracleasm/disks/ASMDISK10' is not in the discovery set (DBD ERROR: OCIStmtExecute)

如果根据disktring找不到合适的磁盘，会报错，使用用这个修改还是比较靠谱的，因为这个会做验证。
lsct 列出V$ASM_CLIENT的信息
Lists information about current Oracle ASM clients from the
V$ASM_CLIENT view. A client, such as Oracle Database or Oracle ASM
Dynamic Volume Manager (Oracle ADVM), uses disk groups that are manage
by the Oracle ASM instance to which ASMCMD is currently connected.
ASMCMD> lsct
DB_Name Status Software_Version Compatible_version Instance_Name Disk_Group
+ASM CONNECTED 11.2.0.3.0 11.2.0.3.0 +ASM1 SYSTEMDG
asmvol CONNECTED 11.2.0.3.0 11.2.0.3.0 +ASM1 OHSDBA
pgold CONNECTED 11.2.0.3.0 11.2.0.0.0 pgold1 DATA_PGOLD
ASMCMD>
lsop 列出磁盘或者实例的当前操作
Lists the current operations on a disk group or Oracle ASM instance.
lsop
lsop displays information from the V$ASM_OPERATION view
The following are examples of the lsop command. The examples list
operations on the disk groups of the current Oracle ASM instance.
ASMCMD> lsop
Group_Name Dsk_Num State Power
DATA_PGOLD REBAL WAIT 2
ASMCMD>
lspwusr 列出在ASM密码文件中的用户
List the users from the local Oracle ASM password file
ASMCMD> lspwusr
Username sysdba sysoper sysasm
SYS TRUE TRUE TRUE
ASMSNMP TRUE FALSE FALSE
ASMCMD>
orapwusr 添加/删除/修改密码文件中用户
Add, drop, or modify an Oracle ASM password file user.
orapwusr { { { --add | --modify [--password] }[--privilege {sysasm|sysdba|sysoper} ] } | --delete } user
The options for the orapwusr command are described below.
--add - Adds a user to the password file. Also prompts
for a password.
--delete - Drops a user from the password file.
--modify - Changes a user in the password file.
--privilege role - Sets the role for the user. The options are
sysasm, sysdba, and sysoper.
--password - Prompts for and then changes the password
of a user.
user - the user to add, drop, or modify.
orapwusr attempts to update passwords on all nodes in a cluster.
The command requires the SYSASM privilege to run. A user logged in
as SYSDBA cannot change its password using this command.
ASMCMD> orapwusr --modify --privilege sysoper asmsnmp
ASMCMD> lspwusr
Username sysdba sysoper sysasm
SYS TRUE TRUE TRUE
ASMSNMP FALSE TRUE FALSE
ASMCMD>
shutdown 关闭ASM实例，在尝试shutdown abort ASM实例之前，Oracle强烈建议你关闭数据库和ADVM
Shuts down an Oracle ASM instance.
shutdown [ --normal |--abort|--immediate ]
The options for the shutdown command are described below.
--normal - optional, if no option is specified,
--normal is assumed.
option specified
--abort - Shut down aborting all existing operations.
--immediate - Shut down immediately.
The default action is a normal shutdown.
Oracle strongly recommends that you shut down all database instances
that use the Oracle ASM instance and dismount all file systems mounted
on Oracle ASM Dynamic Volume Manager (Oracle ADVM) volumes before
attempting to shut down the Oracle ASM instance with the abort
(--abort) option.
The following are examples of the shutdown command.
The first example performs a shut down of the Oracle ASM instance with
normal action. The second example performs a shut down with immediate
action. The third example performs a shut down that aborts all existing
operations.
ASMCMD> shutdown --immediate
ORA-15097: cannot SHUTDOWN ASM instance with connected client (process 13952)
ASMCMD> shutdown --abort
ASM instance shutdown
Connected to an idle instance.
ASMCMD>
spbackup 备份ASM实例的SPFILE
Backs up an Oracle ASM SPFILE.
spbackup source destination
The options for the spbackup command are described below:
source - specifies the source name
destination - specifies the destination name
spbackup does not affect the GPnP profile. The backup file that is
created is not a special file type and is not identified as a SPFILE.
The file cannot be copied with spcopy. To copy this backup file, use
the ASMCMD cp command
The following are examples of the spbackup command.
The first example backs up the Oracle ASM SPFILE from one operating
system location to another. The second example backs up the SPFILE
from an operating system location to the DATA disk group.
ASMCMD> spbackup +OHSDBA/ohs/spfile.ora +systemdg/spfile.ora.bak
spcopy 复制asm spfile到新的位置，加-u会更新GPnp profile，如果没加，可以通过spset设置
Copies an Oracle ASM SPFILE from source to destination.
spcopy [-u] source destination
The options for the spcopy command are described below.
-u - Updates the Grid Plug and Play (GPnP) profile.
source - Specifies the source file name.
destination - Specifies the destination.
After copying the SPFILE, you must restart the instance with the
SPFILE in the new location if you want to use that SPFILE. When the
Oracle ASM instance is running with the SPFILE in the new location,
you can remove the source SPFILE.
ASMCMD> spcopy +SYSTEMDG/ohs-cluster/asmparameterfile/registry.253.911134633 +DATA_PGOLD/spfile.ora
ASMCMD>
spget 从GPnp中获取asm spfile的位置
Retrieves the location of the Oracle ASM SPFILE from the Grid Plug
and Play (GPnP) profile.
ASMCMD> spget

ASMCMD>
spmove 移动asm spfile到目的地，并更新GPnp profile
Moves an Oracle ASM SPFILE from source to destination and
automatically updates the GPnP profile.
ASMCMD> spget

startup 启动asm实例
Starts up an Oracle ASM instance.
startup [--nomount] [--restrict] [ --pfile pfile ]
The options for the startup command are described below.
--nomount - Specifies no mount operation.
--restrict - Specifies restricted mode.
--pfile pfile - Oracle ASM initialization parameter file.
The default action is a start up that mounts disk groups and enables
Oracle ADVM volumes.
The following is an example of the startup command that starts the
Oracle ASM instance without mounting disk groups and uses the asm_init.
ora initialization parameter file.
ASMCMD> startup --nomount --pfile asm_init.ora
