5.68 SCSIMOUNT (Automatic SCSI tape mounts)

5.68.1 Function

The SCSIMOUNT parameter specifies whether automatic detection of SCSI tape mounts is enabled or
not.

NOTE! Enabling this option may negatively impact Hercules performance depending on how the host
operating system (Windows, Linux etc.) handles SCSI attached tape drive status queries.

5.68.3 Parameter

NO

NO indicates that the SCSIMOUNT option is disabled, forcing all SCSI tape mounts
to be done manually via an appropriate DEVINIT command.

YES

Yes enables the option and causes periodic queries of the SCSI tape drive in a five
second interval to automatically detect when a tape is mounted. YES is equivalent
with “SCSIMOUNT 5”.

secs

A value from 1 to 99 seconds (inclusive) enables this option and causes periodic
queries of the SCSI tape drive to automatically detect if a tape is mounted.

5.68.4 Examples

Example 1:

Enable automatic detection of SCSI tape mounts and set the periodic queries of the SCSI tape drive to a
30 seconds interval.

AUTO_SCSI_MOUNT 30

5.69 SHCMDOPT (Shell command option)

5.69.1 Function

The SHCMDOPT system parameter defines the behaviour of the shell (sh) command. It specifies if shell
commands (sh) are globally enabled or disabled either directly via the Hercules hardware console or pro-
grammatically via the DIAG8CMD interface.

5.69.3 Parameter

DISABLE

When set to DISABLE, shell commands (sh) are globally disabled and will result in
an error if entered either directly via the Hercules hardware console or program-
matically via the DIAG8CMD interface.

ENABLE

When set to ENABLE, shell commands (sh) are globally enabled either directly via
the Hercules hardware console or programmatically via the DIAG8CMD interface.
This is the default.

DIAG8

When DIAG8 is specified (which is the default) the programmatic execution of shell
commands (sh) via the DIAG8CMD interface is enabled. This is the default.

NODIAG8

When NODIAG8 is specified only the programmatic execution of shell commands
via the DIAG8CMD interface is disabled; shell commands (sh) entered directly via
the Hercules hardware console will still work.

NOTE: "entered directly via the Hercules hardware console" includes commands entered via the HTTP
server facility or entered via "run command" (.rc) scripts.
