<h1 class="topictitle1">Use the mounted category to load groups of tapes into a tape device</h1>
<div><p>The mounted category allows a group of tapes to automatically be
loaded into a tape device.</p>
<p>The media are mounted in the order in which they were placed into the category.
It is similar in function to an Automatic Cartridge Loader (ACL) on the stand-alone
3490 devices. This function is available with the Set Tape Category (SETTAPCGY)
command. The mounted category is provided for all tape library devices.</p>
<p>To load groups of tapes into a tape device for 3494 devices, use the Library
Manager software. To load groups of tapes into a tape device for libraries
other than the 3494, use i5/OS™ (the SETTAPCGY command). Because of this difference,
the 3494 Library Manager software loads the next tape as soon as the previous
tape is unloaded. For all other libraries, the tape resource is not loaded
until a tape command requiring media is issued to the tape library device.</p>
<p>With a category of mounted, a tape resource is dedicated for category mount
operations until a SETTAPCGY (*DEMOUNTED) command is issued. When the SETTAPCGY
has been issued, any i5/OS command to the tape library device with VOL(*MOUNTED)
will be directed to the tape resource that is set up for the mounted category.</p>
<p>One category of cartridge can be mounted per available tape resource. To
mount more than one category for a tape library the MNTID parameter must be
used with the SETTAPCGY command to identify the mounted category operations.
A job can only have one mounted category session active at a time. The mounted
category session can be released from the job that mounted the category of
cartridges and can be assigned to another job by using the *RELEASE and *ASSIGN
options on the SETTAPCGY command.</p>
<div class="note"><span class="notetitle">Notes:</span> <ol><li>Tape management systems are notified when a category of cartridges is
mounted and demounted. When a command comes from a user to VOL(*MOUNTED),
the tape management system has the ability to accept or reject the operation. </li>
<li>BRMS does not use the category of mounted to perform its processing. Using
the mounted category in combination with BRMS functions is not recommended.
Mounting a category of cartridges while concurrently using BRMS to perform
tape operations can have unpredictable results.</li>
