The TAPE command (abbreviated TA) generates an SLT from system configuration information. The configuration is written to the CONFIG group of the SYS account on the tape.

TAPE has the following syntax:


   TAPE { [MODE = ][VERBOSE
                    NOCHANGE
                    NOCONFIG
                    NODIAG
                    NOLOGNUM
                    LOGNUM  ]
        {[DEST = ]OFFLINE }
        { [STORE = ]"filesetliststring"}

VERBOSE prompts the TAPE command to list the number of nonuser files to be dumped and lists the name of each file as it is dumped to the boot tape.

By default, SYSGEN changes SYSFILE configurations as they are dumped to tape, so source name equals the destination name.

NOCHANGE prevents SYSGEN from changing the names in the SYSFILE configurator as it makes the boot tape.

NOCONFIG prevents SYSGEN from dumping the current configuration files as it makes the tape.

NODIAG prevents SYSGEN from dumping the diagnostic files as it makes the tape.

NOTE: Using this parameter creates a tape that does not contain a complete system. Installing from this tape may not produce a bootable system.

NOLOGNUM resets the system and datacom log numbers to zero (0).

LOGNUM is the default. It specifies that SYSGEN should carry forward the system and datacom log numbers and not reset to zero (0).

OFFLINE directs the listing created by VERBOSE to SYSGEN's listing file, SYSGLIST.

Using OFFLINE in the TAPE command line does not immediately generate a printout. The information is sent to SYSGLIST until you enter the global module OCLOSE command or exit SYSGEN. Exiting SYSGEN or using OCLOSE closes SYSGLIST and prints the file.

STORE allows the user files that are specified in the file set list to be stored after the SLT. (The filesetliststring parameter is the same as the parameter specified with the STORE utility.

All configuration changes made are reflected on the tape. (The temporary changes remain valid after SYSGEN has generated a tape.) Tapes created by the TAPE command do not contain the system file directory.

NOTE: SYSGEN detects all system-independent errors; however, due to SYSGEN's lack of knowledge of the physical attributes of a target system, system-dependent errors cannot be detected when a system load tape is generated.

To generate a system load tape (SLT), perform the following tasks:

Log on to the console as MANAGER.SYS. Enter:


   :HELLO MANAGER[/userpass].SYS[/acctpass]

NOTE: If the user has system supervisor (OP) capability, but not system manager (SM) capability, an SLT can still be made; however no configuration changes can be made. Follow steps 2, 3, 10, and 11.

Activate SYSGEN and access the configuration group that you want to store on the boot tape. Enter:

Example 4-8 Accessing a Configuration Group


   :SYSGEN groupname

   SYSGEN version D.01.01 : catalog version D.01.00    TUE, SEP 14, 1993

           io                log (lo)       misc (mi)
   spu (sp)
           sysfile (sy)

           basegroup (ba)    keep (ke)      permyes (pe)

   oclose (oc)
           redo
   sysgen>

Make any desired changes from the IO, LOG, or MISC configurators.
Refer to Chapter 5 Modifying Input/Output (I/O) Configurations and Chapter 7 Modifying Miscellaneous Configuration Elements for information on using the IO, LOG, and MISC configurators to alter the system configuration.
After completing any changes, but before exiting a configurator, enter:
```
   HOLD
```
The HOLD command saves changes (to a temporary file) made in the configurator at the time that the HOLD is issued.
Decide which files to dump to tape.
SYSGEN allows you to choose which files to store to a boot tape. You may store autoboot images, boot images, and system programs.
The SYSFILE configurator provides the utilities and commands that alter boot tape contents. For information on the commands available for adjusting boot tape contents, refer to Chapter 8 Modifying System File Configurations
Hold any changes made in step 6.
After completing any changes, but before exiting the configurator, enter:
```
   sysfile>HOLD
```
Exit the SYSFILE configurator. Enter:
```
   sysfile>EXIT
```
Issue the KEEP command to store all changes to a set of permanent disk files by entering:
```
   sysgen>KEEP groupname
```
Mount a write-enabled tape on the tape drive.
When you mount the tape on the tape drive, the system issues a message similar to the following:
```
   10:15/10/Vol (unlabeled) mounted on LDEV# 7
```
Generate the tape.
- To create only a system load tape (SLT), enter the following command:
```
   sysgen>TAPE
```
  This is a tape containing the operating system and specified configuration information.
- To create a system load tape with user files stored after it, enter the following command:
```
   sysgen>TAPE STORE="filesetlist"
```
  You can list the user files that you wish to store as input to the STORE= parameter. Note that the string of file names to be stored after the SLT must be enclosed in quotes. You can also use the wildcard @ to include all users files on the system (@.@.@), in specific accounts (@.@.SYS, @.@.AR), and in specific groups of accounts (@.PUB.SYS, @.CURRENT.AR).
The system responds by issuing a message similar to the following:
```
   ?10:15/#92/46/LDEV# FOR "SYSGTAPE" ON TAPE (NUM)
```
Respond to the tape request to start the STORE when the system issues the above message. When the store is complete, the system issues a message indicating that it has completed the tape:
```
   **Boot tape is successfully built**
```
After all the files are stored, unload the tape and write- protect it. Label the tape and store it in a secure location with other backup materials.
