4.3 Establishing a Serial Link to the RAID Subsystem
While StorageWorks Command Console (SWCC) may be used to define and configure
storagesets on the subsystem, it cannot be used to establish a Secure Path environment.
Thus, the Command Line Interface (CLI) must be used to configure the controllers for
multiple-bus mode operation. Controller status may be obtained through use of the SWCC
CLI Window or a terminal emulation program via serial connection.
Use StorageWorks Command Console (serial connection/CLI Window) or a terminal
emulation program such as Hyperterminal to establish a serial connection to the
subsystem. You will use this connection to issue “CLI” commands to the subsystem.
You may use a serial line connection from the host server or from any PC workstation.
Please refer to the Command Console User’s Guide or the Getting Started Guide shipped
with your platform kit for information on how to setup and use a serial connection and the
“CLI Reference Manual” for complete information on CLI commands and syntax.
4.4 Configuring the RAID Subsystem for Secure Path Operation
This section describes how to configure the RAID subsystem controllers for a Secure Path
environment, which includes:
•
Setting the controllers to multiple-bus failover mode
•
“Preferring” (specifying) which RAID controller (SCSI bus path or Fibre Channel
loop) the I/O of each disk will be assigned to upon system boot.
NOTE
Partitioned storagesets and partitioned single-disk units
(controller-based partitioning) cannot function in multiple-
bus failover dual-redundant configurations. Because they
are not supported, you must delete and re-configure these
storagesets before configuring the controllers for multiple-
bus failover. Make sure you use Windows NT Disk
Administrator to delete partitions on drive(s) before you
delete the corresponding storageset(s).
4.4.1 Setting HSZ70 or HSG80 Controllers to Multiple-bus Failover
Secure Path operation requires that the RAID controllers be configured for multiple-bus
failover mode through use of the Command Line Interface (CLI). This is accomplished by
issuing four individual commands, in the sequence provided in this section, at the CLI
prompt. For clarity, the command lines are presented in bold text, and followed by a
description of the action produced or required after each command is issued.
