6.8.3.3 Parameter

devaddr

This is the device address.

devtype

This is the device type. Valid device types are 3410, 3420, 3422, 3430, 3480, 3490,
8809 and 9347.

awsfile

The filename (and path) of the AWSTAPE file or “*”. An asterisk defines an empty
tape station. The tape must be manually be loaded on request.

If the filename starts with the “@” character (at sign), the file then describes a list of
tape emulation files to be loaded in succession. The syntax of each line in this file is
identical to the information that can be coded directly after the device type in the
overall configuration file. Any emulation file name parameter specified in this file
may be substituted by the character “*”, in which case it specifies a set of options to
be applied to all additional emulation files specified in the list.

This function emulates an Automatic Cartridge Feeder (ACF. The ACF is a feature
on Cartridge type tape drives (3480, 3490, etc..) that automatically loads a new
tape when a tape is removed from the drive. There is no real control over this de-
vice by the host as it just keeps on feeding tapes one after the other. Although the

ACF feature is unique to cartridge type systems, the emulation accepts the use of
the same technique for emulated 1/2 inch tapes reel drives as well.

Parameters are appended in succession. In all cases, if the same parameter is
coded more than once, the last instance takes precedence. Therefore it is pos-
sible to specify a set of parameters in the base configuration file, another on an “*”
line and another for each individual line in the list of files. Parameters are then
appended in that order. A SCSI tape device should not be given in a file list.

The remaining parameters are described in section

6.8.3.4 Examples

Example 1:

Define a 3490 tape device on device address 0580. The tape device is an AWSFILE virtual file named
"R0673A.AWS" located in path "/S390/TAPES/".

0580 3490 /S390/TAPES/R0673A.AWS

Example 2:

Define a 3490 tape device on device address 0580. The tape device is an AWSFILE virtual file named
"R0674A.AWS" located in path "/S390/TAPES/". Mount the tape readonly and disable the support for
guest-initiated automatic tape volume mounting for this device.
