Combined SLT and Store Set
MPE/iX allows you to combine an SLT and any store filesets to make a
combined SLT/Store set. This is recommended for DDS devices primarily
whose large capacity allows both the SLT and store filesets to fit on a
single cassette.
In a combined SLT/Store set, the files are stored after the SLT. These
files can be retrieved either by a reload or a separate RESTORE command
which will skip over the SLT.
In order to create a combined SLT/Store set backup, SYSGEN needs to be
invoked. The option STORE is added to the TAPE command inside SYSGEN.
The TAPE command looks as follows:
sysgen> help TAPE
tape (ta) [mode = VERBOSE|NOCHANGE|NOCONFIG|NODIAG|
NOLOGNUM|LOGNUM]
[dest = OFFLINE]
[store = filesetlist string]
When the STORE option is used, files will be stored after the SLT as
specified through the filesetlist string. The filesetlist string
parameter is the same as the filesetlist parameter that is specified when
using the STORE command. The only difference is that it specifies a set
of files to be stored after an SLT as opposed to just a normal backup.
An example of how to use the STORE option is as follows:
sysgen> TA STORE = "@.pub.sys"
or
sysgen> TA STORE = " "
If the STORE option is used without specifying a filesetlist (2nd
example), which is the same as invoking the STORE command without a
filesetlist, the files that are stored will depend on the user
capabilities. Since the parameter to the STORE option is a string, it
must be enclosed by quotes.
If you want to specify other STORE options like SHOW, PROGRESS etc., they
can be specified through the use of an indirect file:
sysgen> TA STORE = "indirectfile"
where "indirectfile" might contain:
@.@.@.;SHOW;PROGRESS=1
STORE options TRANSPORT, STORESET and MOSET (TurboSTORE) are invalid when
a combined SLT/Store set is being created. If the store results in an
error, the normal STORE errors will be displayed, and the user will be
left in SYSGEN.
Storing files after the SLT will not work for a remote device. The use
of the TAPE command to store files is not backward compatible (prior to
3.1).
When a single reel combined SLT/Store set is used to restore files,
RESTORE will skip past the SLT set automatically prior to restoring
files. In a multi-reel backup, if one of the reels that contain SLT
information is mounted, RESTORE will skip past the SLT beginning with
that reel, that is, reel one does not have to be mounted first in order
for the RESTORE to work.
