7.6.3 asmtool Command Line Reference

asmtool is a command-line interface for marking (or stamping) disks to be used with Oracle ASM.

Option Description Example

-add

Adds or changes stamps. You must specify the hard disk, partition, and new stamp name. If the disk is a raw device or has an existing Oracle ASM stamp, then you must specify the -force option.

asmtool -add [-force]
\Device\Harddisk1\Partition1 ORCLDISKASM0
\Device\Harddisk2\Partition1 ORCLDISKASM2
...

-addprefix

Adds or changes stamps using a common prefix to generate stamps automatically. The stamps are generated by concatenating a number with the prefix specified. If the disk is a raw device or has an existing Oracle ASM stamp, then you must specify the -force option.

asmtool -addprefix ORCLDISKASM [-force]
\Device\Harddisk1\Partition1
\Device\Harddisk2\Partition1
...

-create

Creates an Oracle ASM disk device from a file instead of a partition.

Note: Usage of this command is not supported for production environments.

asmtool -create \\server\share\file 1000
asmtool -create D:\asm\asmfile02.asm 240

-list

List available disks. The stamp, windows device name, and disk size in MB are shown.

asmtool -list

-delete

Removes existing stamps from disks.

asmtool -delete ORCLDISKASM0 ORCLDISKASM1...

If user access control (UAC) is enabled, then you must create a desktop shortcut to a command window. Open the command window using the Run as Administrator, right-click the context menu, and launch asmtool.

Note:

If you use -add, -addprefix, or -delete, asmtool notifies the Oracle ASM instance on the local node and on other nodes in the cluster, if available, to rescan the available disks.
