<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>vos restore</B> command converts a volume dump file previously
|
||
|
|
created with the <B>vos dump</B> command from ASCII into the volume format
|
||
|
|
appropriate for the machine type indicated by the <B>-server</B> argument,
|
||
|
|
and restores it as a read/write volume to the partition named by the
|
||
|
|
<B>-partition</B> argument on that machine. The Volume Server
|
||
|
|
assigns the volume name indicated with the <B>-name</B> argument, and
|
||
|
|
resets the volume's creation timestamp to the time at which the restore
|
||
|
|
operation begins (the creation timestamp is stored in the volume header and
|
||
|
|
reported in the <TT>Creation</TT> field in the output from the <B>vos
|
||
|
|
examine</B> and <B>vos listvol</B> commands.)
|
||
|
|
<P>Use the <B>-file</B> argument to name the dump file, or omit the
|
||
|
|
argument to provide the file via the standard input stream, presumably through
|
||
|
|
a pipe. The pipe can be named, which enables interoperation with
|
||
|
|
third-party backup utilities.
|
||
|
|
<P>As described in the following list, the command can create a completely new
|
||
|
|
volume or overwrite an existing volume. In all cases, the full dump of
|
||
|
|
the volume must be restored before any incremental dumps. If there are
|
||
|
|
multiple incremental dump files, they must be restored in the order they were
|
||
|
|
created.
|
||
|
|
<UL>
|
||
|
|
<P><LI>To create a new read/write volume, use the <B>-name</B> argument to
|
||
|
|
specify a volume name that does not already exist in the Volume Location
|
||
|
|
Database (VLDB), and the <B>-server</B> and <B>-partition</B>
|
||
|
|
arguments to specify the new volume's site. It is best to omit the
|
||
|
|
<B>-id</B> argument so that the Volume Location (VL) Server allocates a
|
||
|
|
volume ID automatically. Do not include the <B>-overwrite</B>
|
||
|
|
argument, because there is no existing volume to overwrite.
|
||
|
|
<P><LI>To overwrite an existing volume at its current site, specify its name and
|
||
|
|
site with the <B>-name</B>, <B>-server</B>, and <B>-partition</B>
|
||
|
|
arguments. The volume retains its current volume ID number unless the
|
||
|
|
<B>-id</B> argument is provided. Specify the value <B>f</B> or
|
||
|
|
<B>i</B> for the <B>-overwrite</B> argument to indicate whether the
|
||
|
|
dump file is full or incremental, respectively.
|
||
|
|
<P><LI>To overwrite an existing volume and move it to a new site, specify its
|
||
|
|
name and the new site with the <B>-name</B>, <B>-server</B>, and
|
||
|
|
<B>-partition</B> arguments. The volume retains its current volume
|
||
|
|
ID number unless the <B>-id</B> argument is provided. The volume is
|
||
|
|
removed from its original site. Specify the value <B>f</B> for the
|
||
|
|
<B>-overwrite</B> argument to indicate that the dump file is a full dump
|
||
|
|
(it is not possible to restore an incremental dump and move the volume at the
|
||
|
|
same time).
|
||
|
|
</UL>
|
||
|
|
<P>If the volume named by the <B>-name</B> argument already exists and the
|
||
|
|
<B>-overwrite</B> argument is omitted, the command interpreter produces
|
||
|
|
the following prompt:
|
||
|
|
<P>
|
||
|
|
<PRE> Do you want to do a full/incremental restore or abort? [fia](a):
|
||
|
|

|
|
<P>Respond by entering one of the following values:

<UL>

<P><LI><B>f</B> if restoring a full dump file
|

<P><LI><B>a</B> or <<B>Return</B>> to cancel the restore operation

</UL>
|

|
|
<P><STRONG>Cautions</STRONG>
|
||
|
|
<P>If the <B>-file</B> argument is omitted, the issuer must provide all
|
||
|
|
other necessary arguments, because the standard input stream is unavailable
|
||
|
|
for responding to the command interpreter's prompts for missing
|
||
|
|
information. In particular, the issuer must provide the
|
||
|
|
<B>-overwrite</B> argument if overwriting an existing volume.
