Connects your terminal to an HSC disk and tape controller through the computer interconnect (CI) bus.

Used only with HSC controllers. Requires the DIAGNOSE privilege.

Format

SET HOST/HSC node-name

Parameter

node-name

Specifies the node name of the HSC.

Description

The SET HOST/HSC command establishes a connection to an HSC disk and tape controller by way of the CI bus. (The SHOW CLUSTER command lists the names of HSC controllers that are accessible to your node.) No password is required to access the HSC; however, only SHOW commands are accepted when the HSC Secure/Enable switch is in the Secure position.

Once the connection is made to the HSC, operations can be performed as if you were attached to the local terminal of the HSC; however, access to ODT (Octal Debugging Tool) and offline diagnostics are not permitted.

Press Ctrl/C to obtain a prompt from the HSC before entering commands. To exit from the HSC and return to the local system, press Ctrl/\.

A description of HSC commands and utilities can be obtained from the HSC documentation.

Preparing for Use

To use the SET HOST/HSC facility, you must first install FYDRIVER, which is the Diagnostic and Utilities Protocol (DUP) driver associated with the CI. To load FYDRIVER, add the following commands to the SYSTARTUP.COM command procedure in the SYS$MANAGER directory:

$ RUN SYS$SYSTEM:SYSGEN CONNECT FYA0/NOADAPTER

This operation requires CMKRNL (change mode to kernel) privilege.

Qualifier

/LOG[=filespec]

/NOLOG (default)

Controls whether a log file of the entire session is kept. If you use the /LOG qualifier without the file specification, the log information is stored in the file HSCPAD.LOG.

Example

$ SET HOST/HSC HSC001
%HSCPAD-I-LOCPROGEXE, Local program executing - type ^\ to exit, ^Y for prompt
HSC>
      

This SET HOST/HSC command connects the user terminal to the HSC named HSC001.
