Scan

A Scan is used to discover all supported tape and library devices that are attached to the computer system so that they can be selected for the subsequent ITDT-GE operations. It also serves as a connection test that can be used to verify proper attachment of the devices.

ITDT-GE will use the IBM Tape Device Driver for its operations. If no IBM Tape Device Driver is installed, the operating system generic device driver will be used instead. Any tape device driver that is installed will be used.

Before continuing, make sure no other program is accessing the devices used by ITDT-GE! Stop the backup jobs which are accessing the devices you want to operate ITDT-GE on or stop the entire backup application, if you are not sure.

Depending on the number of host bus adapters and attached drives, the scan can take several minutes. The device list shows all detected devices with their connection information (host adapter number, bus number, SCSI/FCP ID and LUN) along with product data (model name, unit serial number, firmware revision). For drives which are attached to a tape library, the changer column will show the serial number of the changer the drive is attached to. If no devices appear in the list, make sure that

Specify Device Manually

Specify Device Manually lets you define a tape device and a associated changer device which should be used for testing. This function is a fast alternative to the Scan function where all Host Bus Adapters are discovered for supported tape and changer devices. Specify Device Manually supports the device name and HBTL addressing schema. For stand alone tape devices is the parameter "Changer Device" not required.

Example device name :

\\.\tape0 (Windows) /dev/IBMtape0 (Linux)

Example HBTL :

H1-B0-T3-L0 or 1 0 3 0 (all Platforms)

Partial Scan

Partial Scan should be used instead ofScan is only a particular HBA or target Id range should be used for device discovering. The scan will start at "First device to scan" and it will check for supported devices until "Last device to scan" is reached. Devices specified within "Exclude from scan" will be skipped during the scan. If neither "First device to scan", "Last device to scan" and "Exclude from Scan" is specified ITDT will perform a regular Scan.

Partial Scan supports the device name and HBTL addressing schema.
Example device name :
\\.\tape0 (Windows)
/dev/IBMtape0 (Linux)

Example HBTL :
H1-B0-T3-L0 or 1 0 3 0 (all Platforms)
