                               Update a Drive

This dialog is used to update a drive in the Media Manager device 
configuration.  The dialog can be accessed through the "Update Drive..." 
button in the "Drives" menu on the menu bar.

There are four buttons at the bottom of the dialog.  The OK button will update
the drive in Media Manager's device configuration, and dismiss the dialog.
The Reset button will reset the fields in the form to the currently defined
values. The Cancel button will dismiss the dialog without performing any other 
action. The Help button will display this information.

Drive Type 

Use the Drive Type option menu to select the type of the drive.

Drive Index 

This is the index of the drive. This field can not be changed.

Rewind and No Rewind Device

Rewind and No Rewind devices are the paths of the rewind and no rewind device
files for this drive.

Character, Block, and Volume Header Devices

For optical disk drives a character drive name, block drive name and volume 
header drive name (if applicable) must be entered.

            - /dev/sd2g for block drive name.
            - /dev/rsd2a for volume header (label) drive name.

  HP9000-700 - /dev/rdsk/c201d4s0 for character drive name.
             - /dev/dsk/c201d4s0 for block drive name.

  HP9000-800 - /dev/rdsk/c1d0s12 for character drive name.
             - /dev/dsk/c1d0s12 for block drive name.
             - /dev/rdsk/c1d0s6 for volume header drive name.

  SGI - /dev/rdsk/dks1d4s7 for character drive name.
      - /dev/dsk/dks1d4s7 for block drive name.
      - /dev/rdsk/dks1d4vh for volume header drive name.

  Solaris 2.x - /dev/rdsk/c1t4d0s6 for character drive name.
              - /dev/dsk/c1t4d0s6 for block drive name.
              - /dev/rdsk/c1t4d0s0 for volume header (label) drive name.

  RS6000 - /dev/rhdisk2 for character drive name.
         - /dev/hdisk2 for block drive name.


For more information on device files refer to the following:

  SunOS 4.x - Refer to MAKEDEV(8) for information on creating drive
              names.

  HP9000-700 - Refer to intro(7) and sam(1M) for information on creating
               drive names. Also refer to /usr/openv/volmgr/bin/hp.mkdev,
               which is an interactive script for determining drive names.

  HP9000-800 - Refer to insf(1M) for information on creating drive names.

  SGI - Refer to MAKEDEV(1M) for information on creating drive names.

  Solaris 2.x - Refer to drvconfig(1M) and related man pages for
                information on creating drive names.

  RS6000 - Refer to SMIT for information on configuring drives.

Drive Status

Drive status (up or down) specifies whether the Media Manager device daemon,
ltid(1M), will consider the drive available.  This status may be changed after 
the device daemon is initiated.


Cleaning Frequency

Set the number of hours of mount time that should elapse between drive 
cleanings.  When the drive is added, Media Manager starts recording the amount
of time that volumes have been mounted in that drive.

If the drive is in a robot and a cleaning cartridge has been defined for that
robot, cleaning occurs automatically when the accumulated mount time exceeds 
the time you specify for cleaning frequency.

If the drive is a standalone or if a cleaning tape was not defined, the message
NEEDS CLEANING appears in the Comment field of the Drive Cleaning dialog.

Robotic Drive

Select whether you want the drive to be under robotic control or a standalone
drive. Choose Yes if the drive is in a robotic device. Choose No if the drive is
a standalone drive.

Change Volume Database Host for ALL Standalone Drives

If the drive is a standalone drive, you can set the host that contains the 
volume database for this and ALL other standalone drives.  To be able to change
the volume database host set the Yes toggle button.  When the Yes button is set,
the Standalone Drive Volume Database Host text field can be edited. To change 
the volume database host enter the new volume database host's name in this text 
field.

By default the No toggle is set and the text field contains the name of the 
current standalone volume database host.

        NOTE - Changing the standalone volume database host affects all 
               standalone drives.


Robot Type

If the drive is in a robotic device, select the type of robotic device.  Only
the robot types valid for this drive type will be selectable. This menu applies
only to robotic drives.  It will be greyed out for standalone drives.

To the right of this menu is a list of all the defined robots that could have
a drive of this type.  Selecting a robot from this list will set the Robot Type 
and fill in the Robot Number.

Robot Number

If this is a robotic drive, fill in the robot number for the robot the drive is
in.  This field can be filled in by selecting a drive from the list of defined 
robots.

Robot Drive Number

The Robot Drive number is either the physical position of the drive in the robot
(corresponding to an element address), or, for TLH and TLM robots, an index based 
on the order of configured drives in the robot vendor's software.  The robot drive 
number begins at index 1.  For TLH and TLM robots, use the appropriate robotic test 
utility (tlhtest or tlmtest) to obtain the drive number index that corresponds to
each drive configured in the vendor software (IBM ATL or EMASS DAS).

ACS Drive Information (ONLY for drives in ACS robots)

If updating a drive in an ACS robot, you need to specify information to identify
the drive in terms of the Automated Cartridge System Library Software (ACSLS)
configuration.  This information is used in place of a robot drive number.
