<h1 class="topictitle1">RST Support</h1>
|
|||
|
|
<div><p>RST can be used to select a volume or volumes to restore.</p>
|
|||
|
|
<p>The RST command protocol requires that all physical file systems adhere
|
|||
|
|
to a certain set of predefined rules governing how restore is handled, depending
|
|||
|
|
on whether or not the object exists on the system. For purposes of restoring
|
|||
|
|
an optical volume image, the target media must exist on the system, either
|
|||
|
|
mounted in a stand-alone device or imported into an optical media library.
|
|||
|
|
Also, it must be accessible by the name specified on the OBJ-New Path Name
|
|||
|
|
parameter. The OBJ-New Path Name must either match the name of the OBJ-Name
|
|||
|
|
parameter or be *SAME. This restriction will require that unformatted volumes
|
|||
|
|
be renamed before executing the RST command. Unformatted volumes can be renamed
|
|||
|
|
using option 7 from either the WRKOPTOL, WRKLNK display or by issuing the
|
|||
|
|
generic RNM command.</p>
|
|||
|
|
<p>When an unformatted volume is renamed, the new name acts as an alias to
|
|||
|
|
the unformatted volume. The new name will not be written to the media and
|
|||
|
|
will not be preserved if the volume is removed from the device. The name is
|
|||
|
|
only a temporary volume identifier used to refer to this volume until the
|
|||
|
|
volume is restored.</p>
|
|||
|
|
<p>Saved volumes can be restored to both unformatted and formatted volumes.
|
|||
|
|
If restoring to a formatted volume that contains active files and directories,
|
|||
|
|
an inquiry message is sent. If you proceed with the restore, all data on the
|
|||
|
|
target media will be lost.</p>
|
|||
|
|
<p>Saved HPOFS volumes can be restored to Erasable media with matching sector
|
|||
|
|
sizes and a capacity equal to or greater than the saved volume.</p>
|
|||
|
|
<p>Saved UDF volumes on DVD and Erasable can be restored onto DVD or eraseable
|
|||
|
|
media, but media capacity and sector size must be identical to the saved volume.</p>
|
|||
|
|
<p>WORM volumes can be restored to either WORM or Erasable media as long as
|
|||
|
|
the capacity of the target media is greater than or equal to the saved volume
|
|||
|
|
capacity and the sector size is identical to the saved volume. When restoring
|
|||
|
|
to WORM, the target volume must be unformatted.</p>
|
|||
|
|
<p>The performance of RST is comparable to DUPOPT, although it depends on
|
|||
|
|
the target device chosen.</p>

<div><p><strong>OBJ Name</strong> Name of the optical volume image or images to be restored
|
|||
|
|
from a save/restore device. </p>
|
|||
|
|
<p><strong>OBJ New</strong> Path Name Specify a single or multiple path names. The path
|
|||
|
|
name cannot be extended beyond the volume level. Examples of invalid path
|
|||
|
|
names include, ’/QOPT/VOL/*’ or ’/QOPT/VOL/DIR/FILE’. Specify the names of

|
|
existing volumes or *SAME. </p>
|
|||
|
|
<p><strong>SUBTREE</strong> Must be *STG when restoring optical volume images.</p>
|
|||
|
|
<p><strong>OPTION</strong> Must be *ALL or *OLD.</p>
|
|||
|
|
<p><strong>ALOWOBJDIF</strong> Select *OWNER, *PGP, *AUTL, *NONE, *ALL. The value selected
|
|||
|
|
determines what differences will be tolerated between the saved volume and
|
|||
|
|
the formatted target volume. If changes are allowed, an attempt will made
|
|||
|
|
to preserve the security attributes UID, GID and PERMS of a the UDF target
|
|||
|
|
volume root directory. The *OWNER and *PGP values are not checked when restoring
|
|||
|
|
to an uninitialized volume or when restoring to an initialized HPOFS volume. </p>

values and their meaning.</p>
