Tivoli Storage Manager for Windows Administrator's Reference
Use this command to define a drive that the server can use to access data
on storage volumes. Each drive is assigned to a single library.
You must define this library before you issue this command. You can
define more than one drive for a given library by issuing the DEFINE DRIVE
command once for each drive. Stand-alone drives always require a
manual-type library. For additional information, see
Administrator's Guide.
Privilege Class
To issue this command, you must have system privilege or unrestricted
storage privilege.

Notes:
- The ELEMENT parameter is required for drives in SCSI libraries.
- ACSDRVID is required for drives in ACSLS libraries. This parameter
is not valid for non-ACSLS libraries.
Parameters
- library_name (Required)
- Specifies the name of the library to which the drive is assigned.
This parameter is required for all drives, including stand-alone
drives. The specified library must have been previously defined by
using the DEFINE LIBRARY command.
- drive_name (Required)
- Specifies the name that is assigned to the drive. The maximum
length of this name is 30 characters.
- DEVIce (Required)
- Specifies the name of the device that corresponds to the drive. For
example, you might specify mt5.0.0.1.
For a drive that is device type REMOVABLEFILE, specify its drive letter and
a colon, for example, E:.
This parameter is required for SCSI and 349X library types, but is not
valid for MANUAL, EXTERNAL, or ACSLS libraries. If the library type is
SCSI, only one device name is allowed. If the library type is 349X, you can specify 1 to 8 device names by
separating the names with commas and no intervening spaces.
For devices that are supported by either the ADSMSCSI driver or Windows
drivers, use an alias name to refer to the devices when using TSM. The
alias name replaces the real ADSMSCSI name or Windows name for a device in TSM
commands and screens.
An alias name has the form mtx.y.z.n or
lbx.y.z.n. The mt indicates
that the device is a tape device, and the lb indicates that the
device is the controller for a tape autochanger or an automated
library. The alias can be abbreviated. Some examples
follow:
- mt3
- Tape drive at SCSI ID 3, LUN 0 on bus 0, port 0
- lb4.1
- Library at SCSI ID 4, LUN 1 on bus 0, port 0
- mt5.0.1
- Tape drive at SCSI ID 5, LUN 0, bus 1, port 0
Because the alias name does not change unless you change how the device is
physically attached, always use the alias name for devices that are controlled
by Windows device drivers. To distinguish between a real device name
and an alias, TSM checks for a backslash (\) at the beginning of the
name. If the name begins with a backslash, TSM recognizes that the name
is the real device name and not an alias.
- ONLine
- Specifies whether the drive is available for use. This parameter is
optional. The default is YES.
- Yes
- Specifies that the drive is available for use.
- No
- Specifies that the drive is not available for use.
- ELEMent
- Specifies the element address of the drive within a SCSI library.
This parameter is optional and is only valid for a drive located in a SCSI
library. It is not required for drives in a library defined as
SHARED. The server needs the element address to connect the physical
location of the drive to the drive's SCSI address. To find the
element address for your library configuration, consult the
manufacturer's information. You can also access the TSM Web site
at:
http://www.tivoli.com/support/storage_mgr/tivolimain.html
. At this URL, follow the links to device information. You will
need to click on your product and platform and then scroll to the required
device. Click on your selected device to see element addresses.
- ACSDRVID
- Specifies the ID of the drive that is being accessed. The drive ID
is a set of numbers that indicates the physical location of a drive within an
ACSLS library. This drive ID must be specified as a,l,p,d,
where a is the acsid, l is the LSM (library storage
module), p is the panel number, and d is the drive
ID. The server needs the drive ID to connect the physical location of
the drive to the drive's SCSI address. See the STK documentation
for details.
- CLEANFREQuency
- Specifies how often the server activates drive cleaning. This
parameter is optional. The default is NONE. For the most
complete automation of cleaning for an automated library, you must have a
cleaner cartridge checked into the library's volume inventory. For
details on using this parameter for automated and manual libraries, see
Administrator's Guide.
Note: | Do not use drive cleaning that is controlled by the server for SCSI libraries
that have automatic drive cleaning support in their device hardware.
|
- NONE
- Specifies that the server does not track cleaning for this drive.
Use this value for libraries that have their own automatic cleaning.
- ASNEEDED
- Specifies that the server loads the drive with a checked-in cleaner
cartridge only when a drive reports to the device driver that it needs
cleaning.
- value
- Specifies (in gigabytes) how much data to process on the drive before the
server loads the drive with a cleaner cartridge. The server resets the
gigabytes-processed counter each time it loads a cleaner cartridge in the
drive.
Consult the drive manufacturer's information for cleaning
recommendations. If the information gives recommendations for cleaning
frequency in terms of hours of use, convert to a gigabytes value by doing the
following:
- Use the bytes-per-second rating for the drive to determine a
gigabytes-per-hour value.
- Multiply the gigabytes-per-hour value by the recommended hours of use
between cleanings.
- Use the result as the cleaning frequency value.
Usage Notes
- When issuing the DEFINE DRIVE command for a removable drive, a formatted
medium must be present in the drive. For a REMOVABLEFILE device type,
the server does not supply utilities to format or label the media. You
must use the device manufacturer's utilities or operating system utilities
to format and label the media. Such utilities may include the format
and label commands. The label on the media must not contain more than 8
characters, embedded blanks, or periods. The label must also follow the
operating system's rules for file names. This allows the server to
verify that a valid file system is available.
- If your SCSI adapter allows the system to see attached drives as either
fixed disks or removable, make sure the system views the attached drive as
removable.

You have already defined a manual library named MANUAL using the DEFINE
LIBRARY command. You now want to inform the server that you have a
stand-alone Iomega Zip drive that is accessed as drive letter H and is ready
for use. You choose the name ZIP1 for this drive.
