sbdadm - SCSI Block Disk command line interface

sbdadm create-lu [-s, --size size] filename

sbdadm delete-lu lu_name

sbdadm import-lu lu_name

sbdadm list-lu lu_name

sbdadm modify-lu [-s, --size size] lu_name | filename

The sbdadm command creates and manages SCSI-block-device-based logical units that are registered with the SCSI Target Mode Framework (STMF).

The sbdadm command supports the subcommands listed below. Note that if you enter a question mark as an argument to the command (sbdadm ?), sbdadm responds with a help display.

create-lu [-s, --size size] filename

Create a logical unit that can be registered with the STMF. For the -s option, size is an integer followed by one of the following letters, to indicate a unit of size:













If you do not specify size, the size defaults to the size of filename.

The size specified can exceed the size of the file or device.

delete-lu lu_name

Deletes an existing logical unit that was created using sbdadm create-lu. This effectively unloads the logical unit from the STMF framework. Any existing data on the logical unit remains intact.

import-lu lu_name

Imports and loads a logical unit into the STMF that was previously created using sbdadm create-lu and was since deleted from the STMF using sbdadm delete-lu. On success, the logical unit is again made available to the STMF. filename is the filename used in the sbdadm create-lu command for this logical unit.


List all logical units that were created using the sbdadm create-lu command.

modify-lu [-s, --size size] lu_name | filename

Modifies attributes of an logical unit created using the sbdadm create-lu command. For the -s option, size is an integer value followed by a unit specifier. The unit specifiers are as described above under create-lu. When this option is specified, the existing size of the logical unit is changed to the new size.

The size specified can exceed the size of the file or device represented by lu_name.

sbdadm use the following operands:


Name of an existing file or a fully qualified path to a raw block device.


The 32-byte hexadecimal representation of the logical unit.

Example 1 Creating a Logical Unit

The following series of commands creates a 10-gigabyte logical unit.

# touch /export/lun/0
# sbdadm create-lu -s 10g /export/lun/0
# sbdadm create-lu /dev/rdsk/c1t1d0s0

Example 2 Listing Logical Units

The following command lists all logical units.

# sbdadm list-lu
