Media Management 4.11 Volumes needed. The slot field indicates the magazine slot the volume is in (this may or may not be the same as the jukebox slot). When the volume is in a magazine, its onsite and offsite location and date fields are invalid, as the magazine’s onsite and offsite location and dates are used instead. • Offsite Location - The designated offsite location for the volume (not valid if the volume is in a magazine) • Onsite Location - The designated onsite location for the volume (not valid if the volume is in a magazine). The Space field indicates which space in the onsite location the volume is in or would be in if the placement is onsite. 4.11.9 Formats - Brand, Format, Block Factor, Record Size 4.11.10Protection 4.11.11Counters The format fields are not used by ABS, HSM or MDMS, but can be used to document certain characteristics of the volume and its data format. The fields are as follows: • Brand - The manufacturer of the volume - string • Format - The record format used on the tape volume. Options are: – ASCII – BACKUP – EBCDIC – NONE 4.11.12Allocate Volume – RMUBACKUP • Record Size - An integer • Block Factor - An integer The protection field provides System, Owner, Group and World access protection for the volume. This protection is written to the volume when it is initialized, and provides protection from unauthorized use and re-initialization. The standard protection is: SYSTEM(R, W) OWNER (R, W) GROUP (R) WORLD (None) If protection is not set for the volume, the domain default protection is used. MDMS provides three counters for volumes, as follows: • Mount Count - This is a count of the number of times the volume is loaded - maintained by MDMS and incremented every time MDMS loads this volume • Error Count - Not maintained by MDMS - set this field any integer you wish • Times Cleaned - If the volume is a cleaning volume, this value is incremented each time the volume is loaded and used for cleaning. Otherwise it is set to 0. You allocate volumes so that you can use them for writing new data. Allocating a volume places it into the Allocated state, and assigns the calling user (or specified user), UIC, and account in the allocation fields. This effectively reserves the volume to the user. The volume remains allocated to the user and unavailable for other use until the scratch date is reached, or unless the volume is manually deallocated. 4-24 Media Management
Media Management 4.11 Volumes When allocating a volume, you may specify the user for which you are allocating the volume (for example, ABS). If you do not specify a user, then you as the calling user are placed in the allocation fields. Also, during allocation, you can change the following fields in the MDMS database to reflect the format to be used on the tape: • Format - The record format used on the tape volume. Options are: – ASCII – BACKUP – EBCDIC – NONE – RMUBACKUP • Record Size - An integer • Block Factor - An integer • Scratch Date - The date when the volume’s data becomes obsolete and the volume should be deallocated - MDMS will automatically deallocate the volume at this time. • Transition Time - When the volume is deallocated, the volume should go into the Transition State and remain in this state until the transition time expires, after which it will go into the Free State. If not specified, the volume goes into the Free State immediately on deallocation. 4.11.13Allocate Volume(s) by Selection Criteria Instead of allocating a volume by name, you can specify selection criteria to be used for MDMS to select a free volume for you and allocate it. You can also allocate a volume set by specifying a count of volumes to allocate. The allocation selection criteria include: • Media Type - Select a volume with the specified media type • Location - Used with media type, select a volume in the specified location • Jukebox - Used with media type, select a volume in the specified jukebox • Pool - Select a volume in the specified pool • Like Volume - Select a volume like the specified volume (with the same media type, pool and placement) • Bind Volume - Select a volume like the specified volume (with the same media type, pool and placement) and bind the new volume to the specified volume in a volume set If you specify a volume count of more than one, then that many volumes will be allocated and placed in a volume set. If you also use the “Bind Volume” selection option, the new volume set is bound to the specified volume set. You can also specify that you wish to change certain attributes of the volume as follows: • Format - The record format used on the tape volume. Options are: – ASCII – BACKUP – EBCDIC – NONE – RMUBACKUP Media Management 4–25

The <strong>for</strong>mat fields are not used by ABS, HSM or MDMS, but can be used <strong>to</strong> document certain<br />
characteristics of the volume and its data <strong>for</strong>mat. The fields are as follows:<br />
• Brand - The manufacturer of the volume - string<br />
• Format - The record <strong>for</strong>mat used on the tape volume. Options are:<br />
– ASCII<br />
– BACKUP<br />
– EBCDIC<br />

• Record Size - An integer<br />
• Block Fac<strong>to</strong>r - An integer<br />
The protection field provides <strong>System</strong>, Owner, Group and World access protection <strong>for</strong> the volume.<br />
This protection is written <strong>to</strong> the volume when it is initialized, and provides protection from<br />
unauthorized use and re-initialization. The standard protection is:<br />
SYSTEM(R, W) OWNER (R, W) GROUP (R) WORLD (None)<br />
If protection is not set <strong>for</strong> the volume, the domain default protection is used.<br />
MDMS provides three counters <strong>for</strong> volumes, as follows:<br />
• Mount Count - This is a count of the number of times the volume is loaded - maintained by<br />
MDMS and incremented every time MDMS loads this volume<br />
• Error Count - Not maintained by MDMS - set this field any integer you wish<br />
• Times Cleaned - If the volume is a cleaning volume, this value is incremented each time the<br />
volume is loaded and used <strong>for</strong> cleaning. Otherwise it is set <strong>to</strong> 0.<br />
You allocate volumes so that you can use them <strong>for</strong> writing new data. Allocating a volume places<br />
it in<strong>to</strong> the Allocated state, and assigns the calling user (or specified user), UIC, and account in<br />

<strong>to</strong> the user and unavailable <strong>for</strong> other use until the scratch date is reached, or unless the volume<br />
