Installing and Configuring Device Drivers

To use a device, you must install the appropriate device driver. Tivoli Storage Manager provides its own device driver for non-IBM devices. The IBM device driver Atape is supported for IBM devices. These device drivers are available on the ftp site ftp://ftp.software.ibm.com/storage/devdrvr/. Tivoli Storage Manager also supports third party vendor device drivers if the devices are associated with the GENERICTAPE device class and the hardware vendor also supports that device driver. Using a device class other than GENERICTAPE with a third party vendor device driver is not recommended.

IBM tape drives and libraries
Install the device driver that IBM supplies. See Installing Device Drivers for IBM SCSI Tape Devices, Installing Device Drivers for IBM 349X Libraries.

Non-IBM tape drives and autochangers
You must ensure that you have installed the appropriate device drivers. When you install Tivoli Storage Manager, you must choose whether to install the Tivoli Storage Manager device driver or the native operating system device driver for tape devices.

Optical devices
Install the TSM device drivers. See http://www.tivoli.com/support/storage_mgr/tivolimain.html and Configuring Device Drivers for Non-IBM Tape or Optical Drives.

Determining Device Special File Names

To work with removable media devices, Tivoli Storage Manager needs the device's special file name. You specify the device special file name when you issue the DEFINE PATH commands for drives and libraries. You can use SMIT to get the device special file.

When a device configures successfully, a logical file name is returned. Table 9 specifies the name of the device (or the special file name) that corresponds to the drive or library. In the examples, x denotes any number from 0 to 9.

Table 9. Device Examples

Device Device Example Logical File Name
Tape drives that are supported by the Tivoli Storage Manager device driver /dev/mtx mtx
SCSI-attached libraries that are supported by the Tivoli Storage Manager device driver /dev/lbx lbx
Optical drives that are supported by the Tivoli Storage Manager device driver /dev/ropx opx
Drives associated with the GENERICTAPE device type /dev/rmtx rmtx

Installing Device Drivers for IBM SCSI Tape Devices

To install the device drivers for IBM 3490, 3570, 358X, and 3590 devices, see

After completing the procedure in the manual, you receive a message from the system:

Installing Device Drivers for IBM 349X Libraries

For an IBM 3494 or 3495 Tape Library Dataserver, refer to IBM SCSI Tape Drive, Medium Changer, and Library Device Drivers: Installation and User's Guide (GC35-0154). After completing the procedure in the manual, you will receive a message (logical filename) of the form:

lmcpx Available

where x is a number assigned automatically by the system. Use this information to complete the Device Name field on your worksheet. For example, if the message is lmcp0 Available, enter /dev/lmcp0 on the worksheet in the Device Name field for the library. Always use the /dev/ prefix with the name provided by the system.

Configuring Device Drivers for Non-IBM Libraries

Use the procedure in this section to configure Tivoli Storage Manager device drivers for autochangers for non-IBM libraries.

Run the SMIT program to configure the device driver for each autochanger or robot:

  1. Select Devices.
  2. Select TSM Devices.
  3. Select Library/MediumChanger.
  4. Select Add a Library/MediumChanger.
  5. Select the TSM-SCSI-LB for any TSM supported library.
  6. Select the parent adapter to which you are connecting the device. This number is listed in the form: 00-0X, where X is the slot number location of the SCSI adapter card.
  7. When prompted, enter the CONNECTION address of the device you are installing. The connection address is a two-digit number. The first digit is the SCSI ID (the value you recorded on the worksheet). The second digit is the device's SCSI logical unit number (LUN), which is usually zero, unless otherwise noted. The SCSI ID and LUN must be separated by a comma (,). For example, a connection address of 4,0 has a SCSI ID=4 and a LUN=0.
  8. Click on the DO button.

    You will receive a message (logical filename) of the form lbX Available. Note the value of X, which is a number assigned automatically by the system. Use this information to complete the Device Name field on your worksheet.

    For example, if the message is lb0 Available, the Device Name field is /dev/lb0 on the worksheet. Always use the /dev/ prefix with the name provided by SMIT.

Configuring Device Drivers for Non-IBM Tape or Optical Drives

Use the procedure in this section to configure Tivoli Storage Manager device drivers for non-IBM tape or optical drives.

Attention: Tivoli Storage Manager cannot write over tar or dd tapes, but tar or dd can write over TSM tapes.

Note:
Tape drives can be shared only when the drive is not defined or the server is not started. The MKSYSB command will not work if both Tivoli Storage Manager and AIX are sharing the same drive or drives. To use the operating system's native tape device driver in conjunction with a SCSI drive, the device must be configured to AIX first and then configured to Tivoli Storage Manager. See your AIX documentation regarding these native device drivers.

Run the SMIT program to configure the device driver for each drive (including drives in libraries) as follows:

  1. Select Devices.
  2. Select TSM Devices.
  3. Select Tape Drive or Optical R/W Disk Drive, depending on whether the drive is tape or optical.
  4. Select Add a Tape Drive or Add an Optical Disk Drive, depending on whether the drive is tape or optical.
  5. Select the TSM-SCSI-MT for any supported tape drive or TSM-SCSI-OP for any supported optical drive.
  6. Select the adapter to which you are connecting the device. This number is listed in the form: 00-0X, where X is the slot number location of the SCSI adapter card.
  7. When prompted, enter the CONNECTION address of the device you are installing. The connection address is a two-digit number. The first digit is the SCSI ID (the value you recorded on the worksheet). The second digit is the device's SCSI logical unit number (LUN), which is usually zero, unless otherwise noted. The SCSI ID and LUN must be separated by a comma (,). For example, a connection address of 4,0 has a SCSI ID=4 and a LUN=0.
  8. Click on the DO button. You will receive a message:

Managing SCSI Devices and Fibre Channel Devices

The Tivoli Storage Manager device definition menus and prompts in SMIT allow for the management of both SCSI and FCP attached devices. The main menu for Tivoli Storage Manager has two options:

SCSI Attached Devices
Use this option to configure SCSI devices that are connected to a SCSI adapter in the host. The subsequent menus which have not changed configure devices

Fibre Channel system area network (SAN) Attached Devices
Use this option to configure devices that are connected to a Fibre Channel adapter in the host. Choose one of the following:

List Attributes of a Discovered Device
Lists attributes of a device known to the current ODM database.

FC Port ID:

This is the 24-bit FC Port ID(N(L)_Port or F(L)_Port). This is the address identifier that is unique within the associated topology where the device is connected. In the switch or fabric environments, it is usually determined by the switch, with the upper 2-bytes which are non-zero. In a Private Arbitrated Loop, it is the Arbitrated Loop Physical Address(AL_PA), with the upper 2-bytes being zero. Please consult with your FC vendors to find out how an AL_PA or a Port ID is assigned

Mapped LUN ID

This is from an FC to SCSI bridge (also, called a converter, router, or gateway) box, such as an IBM SAN Data Gateway (SDG) or Crossroads 4200. Please consult with your bridge vendors about how LUNs are mapped. It is recommended that you do not change LUN Mapped IDs.

WW Name

The World Wide Name of the port to which the device is attached . It is the 64-bit unique identifier assigned by vendors of FC components such as bridges or native FC devices. Please consult with your FC vendors to find out a port's WWN

Product ID

The product ID of the device. Please consult with your device vendors to determine the product ID.

Discover Devices Supported by TSM
This option discovers devices on a Fibre Channel SAN that are supported by Tivoli Storage Manager and makes them AVAILABLE. If a device is added to or removed from an existing SAN environment, rediscover devices by selecting this option. Devices must be discovered first so that current values of device attributes are shown in the List Attributes of a Discovered Device option. Supported devices on FC SAN are tape drives, autochangers, and optical drives. The Tivoli Storage Manager device driver ignores all other device types, such as disk.

Remove All Defined Devices
This option removes all FC SAN-attached Tivoli Storage Manager devices whose state is DEFINED in the ODM database. If necessary, rediscover devices by selecting the Discover Devices Supported by TSM option after the removal of all defined devices

Remove a Device
This option removes a single FC SAN-attached Tivoli Storage Manager device whose state is DEFINED in the ODM database. If necessary, rediscover the device by selecting the Discover Devices Supported by TSM option after removal of a defined device.

To configure an FC SAN-attached device:

  1. Run the SMIT program.
  2. Select Devices.
  3. Select Tivoli Storage Manager Devices.
  4. Select Fibre Channel SAN Attached devices.
  5. Select Discover Devices Supported by TSM. The discovery process can take some time.
  6. Go back to the Fibre Channel menu, and select List Attributes of a Discovered Device.
  7. Note the 3-character device identifier, which you use when defining a path to the device to Tivoli Storage Manager. For example, if a tape drive has the identifier mt2, specify /dev/mt2 as the device name.
