NAME

       sbdadm - SCSI Block Disk command line interface

SYNOPSIS

       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

DESCRIPTION

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

SUB-COMMANDS
       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 let-
	   ters, to indicate a unit of size:

	   k	kilobyte

	   m	megabyte

	   g	gigabyte

	   t	terabyte

	   p	petabyte

	   e	exabyte

	   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-lu

	   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.

OPERANDS

       sbdadm use the following operands:

       filename

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

       lu_name

	   The 32-byte hexadecimal representation of the logical unit.

EXAMPLES

       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
	 Found 2 LU(s)

			GUID		       DATA SIZE    SOURCE
	 --------------------------------  -----------	------
	 6000ae4000144f21d92c47b0dd650002  10737352704	/export/lun/0
	 6000ae4000144f21d92c47b0de300032  134283264	/dev/rdsk/c1t1d0s0

EXIT STATUS

       0

	   Successful completion.

       non-zero

	   An error occurred.

tran_reset(9E)                                                  Driver Entry Points                                                 tran_reset(9E)

NAME

       tran_reset - reset a SCSI bus or target

SYNOPSIS

       #include <sys/scsi/scsi.h>

        int prefixtran_reset(struct scsi_address *ap, int level);

INTERFACE LEVEL

       Solaris architecture specific (Solaris DDI).

PARAMETERS

       ap              Pointer to the scsi_address(9S) structure.

       level           The level of reset required.

DESCRIPTION

       The  tran_reset() vector in the scsi_hba_tran(9S) structure must be initialized during the HBA driver's attach(9E) to point to an HBA entry
       point to be called when a target driver calls scsi_reset(9F).

       tran_reset() must reset either the SCSI bus, a SCSI target device, or a SCSI logical unit as specified by level.

       level must be one of the following:

       RESET_ALL               Reset the SCSI bus.

       RESET_TARGET            Reset the target specified by ap.

       RESET_LUN               Reset the logical unit specified by ap.

       tran_reset should set the pkt_reason field of all outstanding packets in the transport layer associated with each target  or  logical  unit
       that  was successfully reset to CMD_RESET and the pkt_statistics field must be OR'ed with either STAT_BUS_RESET (if the SCSI bus was reset)
       or STAT_DEV_RESET (if the target or logical unit was reset).

       The HBA driver should use a SCSI Bus Device Reset Message to reset a target device. The HBA driver should use a  SCSI  Logical  Unit  Reset
       Message to reset a logical unit.

       Packets  that  are in the transport layer but not yet active on the bus should be returned with pkt_reason set to CMD_RESET and pkt_statis-
       tics OR'ed with STAT_ABORTED.

       Support for RESET_LUN is optional but strongly encouraged for new and updated HBA drivers. If an HBA driver provides RESET_LUN support,  it
       must  also  create the lun-reset capability with a value of zero for each target device instance represented by a valid ap. The HBA is also
       required to provide the means to return the current value of the lun-reset capability in its tran_getcap(9E) routine, as well as the  means
       to change the value of the lun_reset capability in its tran_setcap(9E) routine.

RETURN VALUES

       tran_reset() should return:

       1        on success.

       0        on failure.

NOTES

       If  pkt_reason already indicates that an earlier error had occurred for a particular pkt, tran_reset() should not overwrite pkt_reason with
       CMD_RESET.
