Configuration Options Descriptions
You can change the following options on the Configure Submenu:
NOTE: Configuration Options defaults are listed below in Table 2–2 .
Set Data Format
This setting allows you to set the data format and enable or disable data compression. This
setting applies to the next or the currently, loaded cartridge only. An unload command
returns to the default. This setting does not display, the format of the loaded tape. Revert
to Show Status Menu for this purpose.
Set SCSI
Allows you to enable or disable the robotics SCSI bus parity checking, and set the SCSI
addresses of the drives and the robotics.
Set Library Mode
This setting lets you switch the robotics operating mode between Random or Sequential.
Random is the normal operating mode which affords complete host control of the robotics.
Sequential mode is locally controlled. Sequential operations begin with any cartridge
loaded into the drive. The library monitors the status of the drive, and when the cartridge
is unloaded by the host, it returns the cartridge to the magazine, then loads the next
cartridge in magazine numerical order. This operation continues to cycle until all of the
cartridges have been loaded, or until an empty slot is encountered.
When you select Sequential, an additional Sequential Mode option is displayed that lets
you select Normal or Recirculate options. Normal Option operates as described above. In
Recirculate mode, instead of stopping after the cartridge in the last slot has been unloaded
by the host, the operation continues by loading the cartridge in Slot 1. Recirculation will
continue until an empty slot is encountered.
Set Element Base
This setting allows you to set the base addresses of each of the three SCSI elements of the
module. In order to identify sources and destination in SCSI commands to the robotics, the
library is divided into elements, each of which is assigned a separate designator or
element
address . The Transport Element is the robotics mechanism itself; the Storage Elements are
slots in the magazines; the Transfer Element the drive. The library reports these settings
in response to the SCSI Mode Sense command, in the Element Address Assignment Page.
Set Identification
This setting enables you to specify the response of the library robotics to the SCSI Inquiry
command in the Vendor ID and the Product ID fields.
