The SLT performs one function, to hold critical files needed to install MPE on your system.

The SLT tape has two parts to it. The first section of the tape is only accessible by either the sysgen TA process which writes the tape,
checkslt in the telesup account which checks it or the install or update options available to you at boot time. The second section of the tape is
only accessible by either the sysgen TA process which writes the tape (take a look at the store option of TA), checkslt in the telesup account
which checks it or the standard restore command. If a restore tries to restore from an SLT it will detect the boot files stored in the first portion of
the tape and skips over them.

You will find a list of the standard files stored in the first portion of the tape in your sys admin manuals.

The magic part about restoring your directory structures comes from the ;directory option of the store and restore commands. If you have
multiple volumes it is necessary to use the ;volumeset= volumesetnames option of the store command to make sure all directory information
about all volumes makes it to the tape. It is customary that restoring a complete system is done in teo passes, the first pass being restore *t;
@[log in to unmask]@;directory to restore the directory structure which you can examine for correctness; then a second pass to restore the data.

The first section of the SLT tape contains the files needed to install MPE including your hardware configuration. You made add to the list of
files using the sy section of sysgen. A prime candidate to be added is your favorite editor so you can create jobs in the event of a problem.
The second section of the SLT tape contains the files you wished to store on the SLT tape, usually @[log in to unmask]

If you use an SLT from another system you will need to change the configuration using sysgen after using install.
