Features of The ISL Utilities
MPE XL uses the ISL utilities and their options to load the system from
tape, start up the system from disk, or dump portions of the memory for
diagnostic purposes. The current boot utilities are START, UPDATE,
INSTALL and DUMP.
Table 2-3 provides a general comparison of MPE V/E versus MPE XL
startup procedures.

NOTE MPE XL does not use the RELOAD, COLDSTART, COOLSTART, and WARMSTART
load and startup utility commands. While the command for UPDATE is
the same, it is specified through a command-driven software
interface and provides a variety of new options. Also, MPE XL does
not allow system reconfiguration while booting up.
The following table summarizes the different attributes of the various
MPE XL system startup utilities. The listings include the source from
which the system is booted, whether or not configuration changes are
allowed, whether or not spoolfiles are recovered and permanent user files
retained, and the source (system load tape or system disk) of system
files, configuration, directory structure, and account structure. Table
2-5 provides a more detailed look at each utility.

Table 2-5. Features of the System Load and Start Utilities
---------------------------------------------------------------------------------------------
- UTILITY - FUNCTION -
---------------------------------------------------------------------------------------------
| DUMP | Equivalent to MPE V/E DUMP. Copies the |
| | current system main memory and secondary |
| | (disk) storage to tape. Usually executed |
| | when an analysis of memory is desired. May |
| | be executed with a START option to |
| | automatically reboot the system on |
| | completion of the DUMP. |
---------------------------------------------------------------------------------------------
| INSTALL or INSTALL START | Equivalent to MPE V/E RELOAD. Boots from |
| | tape and instructs system to reboot when it |
| | is done. INSTALL initializes ldev 1, |
| | rebuilds the OS structure, and completely |
| | replaces the contents of the disk boot |
| | files with those on the tape, including |
| | base operating system files and system |
| | configuration files. INSTALL initializes |
| | ldev 1 as a member of the system volume |
| | set. After running INSTALL and START, use |
| | the VOLUTIL utility to add additional |
| | members of the system volume set, and |
| | nonsystem volumes (Refer to Chapter 5 of |
| | this manual, or Volume Management |
| | (32650-90045). |
---------------------------------------------------------------------------------------------
| INSTALL NOSTART | Boots from tape; prevents automatic |
| | execution of START. |
---------------------------------------------------------------------------------------------
- START or START RECOVERY - -
| Used when configuration unchanged. | Equivalent to MPE V/E WARMSTART. Boots |
| | system from disk and restarts all normal |
| | system functions. Recovers jobs and |
| | spoolfiles; Do not use if system |
| | configuration has been changed. |
---------------------------------------------------------------------------------------------
| START or START NORECOVERY Used when | Equivalent to MPE V/E COOLSTART. Boots |
| configuration is changed. In such case, | system from disk; does not recover |
| START forces NORECOVERY | spoolfiles and jobs. |
---------------------------------------------------------------------------------------------
| UPDATE or UPDATE NOCONFIG | Equivalent to MPE V/E UPDATE. Boots system |
| | from tape; loads configuration files from |
| | disk. Does not recover spoolfiles. |
---------------------------------------------------------------------------------------------
| UPDATE CONFIG | Equivalent to MPE V/E COLDSTART. Boots |
| | system from tape; replaces configuration |
| | files on disk with files from tape. Does |
| | not recover spoolfiles. |
---------------------------------------------------------------------------------------------
NOTE Before using INSTALL to install a new factory supplied UPDATE tape,
copy all system directory files, subsystem files, and user files to
a STORE tape, using MPE XL's STORE/RESTORE facility. After
completion of the installation, use the same facility to restore
the files.
ISL Utility Options
The currently available commands and options are:
Table 2-6. ISL Load and Start Utility Options
--------------------------------------------------------------------------------------------
- OPTIONS - FUNCTIONS -
--------------------------------------------------------------------------------------------
- CONFIG - During an UPDATE, if CONFIG is specified, the -
| NOCONFIG | CONFIG.SYS group on tape replaces the one on disk. |
| | If the |
- - option is not specified, the default is NOCONFIG. -
- Default: NOCONFIG - -
--------------------------------------------------------------------------------------------
- GROUP="cgn" - When performing an UPDATE, INSTALL, or DUMP, and -
| | START is specified or defaulted, "cgn" is the |
| | source of con- |
| | figuration information. When a START command is |
| | entered |
| | (or defaulted), the group specified for it |
| | overrides the |
| | default group previously specified. Since |
| | configuration |
| Default: GROUP=CONFIG | groups reside only in the SYS account, do not |
| | specify the account name (Specify CONFIG, not |
| | CONFIG.SYS). |
--------------------------------------------------------------------------------------------
- LOGON="acct" - The logon acct has the syntax: -
| | user[/ password]. account[[/ password,group [/ |
| | password]]] |
| | When the system is booted, the account specified |
| | after |
| | LOGON= is used to initiate a session. If |
| | SINGLE-USER (see |
| | SINGLE-USER, MULTI-USER option, below) is |
| | specified, the |
| | account specified in LOGON is used as the |
| | "single-user." If |
- Default: LOGON=OPERATOR.SYS - LOGON is not entered in the command line, the logon -
- - defaults to OPERATOR.SYS. -
--------------------------------------------------------------------------------------------
Table 2-6. ISL Load and Start Utility Options (cont.)
--------------------------------------------------------------------------------------------
- OPTIONS - FUNCTIONS -
--------------------------------------------------------------------------------------------
| RECOVERY | During a START or automatic start after a DUMP, |
| | this option |
| NORECOVERY | indicates whether or not restartable jobs and |
| | spoolfiles |
| | are restarted. If RECOVERY is specified, jobs and |
| | spoolfiles |
| | are restarted. On DUMP, this option is only in |
| | effect if |
| | START is specified or defaulted. If this option is |
| | not |
- - specified, the default is RECOVERY. -
| | On INSTALL or UPDATE, jobs and spool files cannot |
| | be |
| Default: Depends on previous | restarted. Thus, the next START defaults to |
| | NORECOVERY. |
- command - Do not use RECOVERY if the NMMGR configuration has -
| | been changed. Instead, use NORECOVERY, which makes |
| | the |
- - change take effect. -
| SINGLE-DISC | This option determines whether or not the system |
| | initiates |
| MULTI-DISC | with all the volumes mounted (MULTI-DISC) or with |
| | only |
- - the system master volume mounted (SINGLE-DISC). If -
- (Primarily Used for Diagnostics) - neither is specified, MULTI-DISC is the default. -
| | SINGLE-DISC may be specified only if SINGLE-USER |
| | has |
| | also been selected. The system issues a warning |
| | message, if |
| | the SINGLE-DISC option is selected with MULTI-USER, |
| | and |
| | changes the SINGLE-DISC option to MULTI-DISC. If |
| | the |
- - START parameter is not specified or defaulted on an -
- Default: MULTI-DISC - INSTALL, UPDATE, or DUMP, the SINGLE-DISC -
- - parameter is ignored. -
--------------------------------------------------------------------------------------------
Table 2-6. ISL Load and Start Utility Options (cont.)
--------------------------------------------------------------------------------------------
- OPTIONS - FUNCTIONS -
--------------------------------------------------------------------------------------------
| SINGLE-USER | This boot option limits the system to a single-user |
| | capability, |
- MULTI-USER - -
- - or permits use by multiple users, with all -
| | configured terminals available. MULTI-USER is the |
| | default. |
| (Primarily Used for Diagnostics) | Single-user mode is used primarily for diagnostic |
| | support. |
- - For the INSTALL, UPDATE, and DUMP utilities, the -
- Default: MULTI-USER - SINGLE-USER/MULTI-USER option is available only if -
- - START is specified or defaulted as an option. -
--------------------------------------------------------------------------------------------
- START - This option instructs UPDATE, INSTALL, or DUMP -
- NOSTART - whether or not to autoboot after the utility has -
| | completed its job. The system autoboots if START |
| | is |
| Default: START | specified. If neither START nor NOSTART is |
| | specified, |
- - START is the default. -
--------------------------------------------------------------------------------------------
- SUBSET= - During a DUMP, this option specifies whether the -
- "All" - contents of main memory, or both main memory and -
| "Memory" | secondary storage, is dumped to tape for later |
| | analysis. If |
| | the subset is not specified, it defaults to "ALL" |
| | (both main |
- Default: SUBSET=ALL - memory and secondary storage). -
--------------------------------------------------------------------------------------------
- SYSSTART - On an INSTALL, UPDATE, START, or DUMP, this -
- NOSYSSTART - option determines whether the system start up -
| | (SYSSTART) file is used during the current boot. |
| | If neither |
| | is specified, SYSSTART (use the system start up |
| | file) is the |
| | default. If the START parameter is not specified |
| | or |
- Default: SYSSTART - defaulted on an INSTALL, UPDATE, or DUMP, the -
- - SYSSTART/NOSYSSTART parameter is ignored. -
