Introduction
5Command Console V2.5 Release Notes
Introduction
The StorageWorks Command Console (SWCC) provides a graphical user
interface that can be used to configure and monitor your storage subsystem. Use
of SWCC is highly recommended. Refer to the HP StorageWorks Command
Console V2.5 User Guide for information about installing and using SWCC.
The SWCC Agent is compiled for each operating system it supports, and is
installed on the host system. The SWCC Client is installed on a Windows Client
within the enterprise.
Identifying Your SWCC Software Revision Level
The SWCC User Guide is identified as V2.5, which refers to the entire software
suite revision. The SWCC Client software suite included in this release of the
Solution Software kit consists of the following components:
■SWCC Command Console, V2.2.0
■SWCC CLI Window, V2.5.0
■HSagent, V2.5.0
■HSG80shim, V2.2.0
■HSG80ACS85 StorageWindow, V2.5.0
■HSG80 StorageWindow, V2.1.0
■HSG60 StorageWindow, V2.5.0
In the above list, the name of each executable is given with its subfolder relative to
the installation folder of the SWCC Client kit.
Verification of the individual components can be done with Explorer by
right-clicking on the particular executable program in its folder and selecting the
Properties option. In the resulting Properties window, click on the Version tab and
select the Product Version to display the version of the program.

New Features in SWCC V2.5
6 Command Console V2.5 Release Notes
New Features in SWCC V2.5
The following new features are available in V2.5:
■The Controller Properties Page > Connections Properties Tab now contains a
delete column used for deleting connections to the controller.
■Client refresh status has been added to the lower status bar of the Client
window.

Known Issues
7Command Console V2.5 Release Notes
Known Issues
This section presents clarifications on the behavior of the software in certain
situations.
Storage Area Network (SAN) Configuration
In a SAN configuration, we recommend that only one SWCC Agent be active at
one time.
Integration with SWCC and Insight Manager
Starting with Insight Manager V4.23, the HSG80 controller can be monitored and
managed from Insight Manager. Insight Manager includes the HSG80 controller
and its status on the Insight Manager storage display. Insight Manager can also
launch the SWCC HSG80 Storage Window to manage storage connected to the
HSG80 controller.
There are two Client versions, HSG80 and HSG80 ACS85. A software "shim" is
included with your solution software kit and must be installed on your Client
station. This "shim" provides access to both HSG80 and HSG80 ACS85 storage
window from Insight Manager.
The "shim" determines which Client version to open. When the HSG80 Storage
Window is opened within Insight Manager, the Storage Window that supports
ACS V8.4 and earlier is launched. The Storage Window will work correctly as
long as it is used with HSG80 controllers that have ACS V8.4 or earlier. When the
HSG80 ACS85 Storage Window opens within Insight Manager it supports ACS
V8.5 or later.
Event Logs
The event log on a Windows NT, Windows 2000, or Windows Server 2003
(32-bit) Client may have extra error message text appended.

Known Issues
8 Command Console V2.5 Release Notes
Special Windows NT Device Driver Required for Compatibility in SCSI-2
Mode
For local SCSI and network connections, the special HSG80 device driver
HSZDISK.SYS, must be installed and running properly to connect the Client to a
host running Windows NT. The device driver makes HSG80 virtual disks visible
to the host operating system and enables communication between the Client,
Agent, and host file system.
Cautions When Configuring from a Configuration File
When configuring a storage subsystem from a configuration file, the program
prompts you to choose whether or not the program initializes your virtual disks.
You must choose the appropriate option or you risk the loss of data as the
configuration file is loaded and your subsystem is configured.
■Do not initialize virtual disks–Choose this option when your virtual disks
contain valuable user data, and you wish to retain that data. You might, for
instance, need to replace a failed subsystem component such as a controller or
cache module. In this case, your subsystem configuration must be transferred
to the new hardware, but you do not wish to change any information on your
storage devices themselves.
■Initialize virtual disks–Choose this option when your virtual disks do not
contain user data, or when you do not care if the data on them is lost. You
might use this option when configuring a storage subsystem from scratch, to
make it match the configuration file.
Virtual Disk Recovery from a Configuration File
Note that when you delete a virtual disk, the disk's member drives are all
re-initialized and all user data is lost. You cannot restore the virtual disk's data by
configuring your subsystem from a configuration file. A configuration file
contains only information about the structure of a virtual disk and does not contain
the disk's data itself.
Virtual Disk Maximum Capacity
The maximum capacity of RAID-based virtual disks is determined by the capacity
of the smallest member, not the largest.
■The maximum capacity of RAID 0 virtual disks is equal to the number of
members times the capacity of the smallest member.

Known Issues
9Command Console V2.5 Release Notes
■The maximum capacity of RAID 1 virtual disks is equal to the capacity of the
smallest member.
■The maximum capacity of RAID 0+1 virtual disks is equal to the number of
members in one stripe times the capacity of the smallest mirrorset member.
■The maximum capacity of RAID 3/5 virtual disks is equal to the number of
members minus one times the capacity of the smallest member.

Operating Constraints
10 Command Console V2.5 Release Notes
Operating Constraints
This section describes the operating constraints for the software. An operating
constraint is a limitation placed on the operation of the controller by the nature of
its design. Keep these constraints in mind, to avoid problems and to help you to
get the maximum performance from your controller.
CLI RUN Commands
Do not issue RUN commands in the CLI Window. Use only a maintenance
terminal connection to issue RUN commands.
Creating Partition Units Across Targets or Ports
Be aware that the name you pick for a unit assigns it to a particular host bus target.
If you create a unit from free space on a device, the program forces you to use a
unit name that puts the unit on the same host target as the other partitions on the
device.
On dual-port controllers, partitions on the same device that are assigned to
different host ports are not supported.
Mirrored Cache Mode Not Retained After Configuration Restore
If you restore your controller configuration from a configuration file, the mirrored
cache setting may not be properly enabled. You must restore the mirrored cache
setting manually, using a CLI Window.
Cache Policy Not Shown in Controller Properties Sheet
The controller cache policy may not be properly shown in the controller properties
sheet. The field may be blank. You must use a CLI Window to obtain the cache
policy setting.
Incorrect Capacity Shown in Add Virtual Disk Wizard
In some circumstances, in Step 3 of the Add Virtual Disk Wizard, if you specify a
capacity greater than the available disk capacity, an error message results. If you
back up to Step 2 of the Wizard and return to Step 3, the correct capacity is then
displayed. An attempt to move to Step 4 of the Wizard at this point, however,
results in the same error message, even though the correct capacity is shown.
