Audience
This document has been prepared for customers who have purchased the Compaq
StorageWorks HSJ80 Array Controller and for Compaq services staff responsible for
installing, configuring, and maintaining systems that include the HSJ80 Array Controller
subsystem.
Identifying Your Array Controller Software Revision Level
The Array Controller Software Kit you received includes the Software Product
Description (AE-RKVDB-TE), the Warranty, and the PCMCIA program card containing
the new Array Controller Software (ACS).
You can identify your current software revision level by entering the
SHOW this_controller command at the Command Line Interpreter (CLI) prompt using the
CLI window from the StorageWorks Command Console (SWCC), a maintenance
terminal, or by way of a Diagnostic and Utility Program (DUP) connection to a host
terminal.
The resulting display lists the software level that is currently installed. When you have
completed the installation process for the new version ACS software, you should see the
following displayed: V85J-2
If the ACS version is not V85J-2 after installation of the new PCMCIA program card,
contact your support provider for instructions on how to obtain the updated version.
Hardware and Software Compatibility
The hardware and operating system software that supports the use of the HSJ80 Array
Controller ACS Version 8.5J-2 is specified in the Compaq StorageWorks HSJ80 Array
Controller ACS Version 8.5J-2 Software Product Description (AE-RKVDB-TE) that
accompanies the PCMCIA program card.
SWCC V2.3 using the HSJ80 StorageWindow V2.2 supports the HSJ80 ACS
Version 8.5J-2 software.
Tape Support
The HSJ80 Array Controller ACS Version 8.5J-2 contains support for tape drives and tape
libraries. This new feature is described in the Compaq StorageWorks HSJ80 Array
Controller ACS Version 8.5J-2 Software Product Description (AE-RKVDB-TE) shipped
with the PCMCIA program card.
Clarifications of Use 5
Clarifications of Use
Table 1 provides clarifications of key aspects of controller operations.
Table 1 Clarifications of Use
Subject Clarification
CLI Command Set Enabling this switch allows additional communications to occur between
Remote Disk Copy Data controllers. These features are not currently supported. Enabling remote disk
copy causes the HSJ80 to form virtual circuits with other controllers. This
may cause HSJ40s and HSJ50s to malfunction due to an incorrect
MAX_HOST count. Do not enable remote disk copy data.
SWCC use with the The StorageWorks Command Console must be upgraded to the version
HSJ80 Array Controller supplied on the software CD-ROM if it is to be used with the HSJ80 Array
Controller subsystem.
Upgrading an HSJ40 or If an HSJ40 or an HSJ50 subsystem is upgraded to an HSJ80, there can be
HSJ50 to an HSJ80 no reversal; the original HSJ40 or HSJ50 subsystem cannot be reinstalled
Array Controller and configured. Drives can be moved from an HSJ40 or HSJ50 upward to an
Subsystem HSJ80. You cannot, however, initialize a drive on an HSJ80 and then
physically move that drive to a system with an HSJ40 or HSJ50, configure,
and mount the drive without reinitializing it. (The metadata stored on the disk
drives is different and incompatible between the HSJ40/HSJ50 and the
HSJ80. During the upgrade procedure from an HSJ40 or HSJ50 to an HSJ80,
the device metadata is updated. This makes the drive unusable on the older
controller. To use these drives on an HSJ40 or HSJ50, they must be initialized
on that controller.)
CIXCD host adapter use If 4 KB packet data transfers are to be used with the HSJ80 Array Controller
with the HSJ80 subsystem, then CIXCD Host Adapters on the same cluster as the HSJ80
must be upgraded to a new firmware level. This firmware upgrade is
supplied on the software solution kit CD-ROM (with the SWCC upgrade).
Largest capacity disk The largest capacity disk drive that may be used with the current version of
drive supported with the the HSJ80 software is 72 GB.
HSJ80 controller
Partition limit There may be no more than eight partitions on a single JBOD or on any
storageset.
Moving disks between When moving disks from one storage set type to another, the disk must be
different storage set initialized prior to being added to the new storage set. For example, if
types DISK10100 is currently a member of a mirror set and it is going to be moved
to a RAID set, then DISK10100 must be initialized before being placed into
the RAID set.

Subject Clarification
DILX and passthrough DILX in automatic mode allocates and attempts to test passthrough devices.
devices This generates various errors from the passthrough device. Either delete all
passthrough devices before running DILX in automatic mode or manually
select which units to test, being careful not to select passthrough devices.
TILX restriction Do not exercise TSZ20 tapes using TILX. The TSZ20 may not function as
expected by TILX and will cause the test to fail.
Operating Constraints
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 achieve
the maximum performance from your controller.
Multi-Cluster Configurations
CAUTION: When using the multi-cluster mode of operation, the port access of the
controllers and the logical units must be set correctly or data loss may occur. See the
following description for additional information.
Problem Description
An HSJ80 Array Controller storage subsystem may be used in a multiple-cluster
configuration using dual Star Couplers and both host ports on both controllers cabled in a
dual-redundant configuration (see Figure 1).
Multiple cluster configurations should be configured with caution as data stored on a disk
with one cluster may be read and written by the other cluster if not configured properly.

Problem Resolution
To avoid the problem, you need to:
s Select the units to be used with a particular cluster
s Enter a series of CLI commands for each container in the subsystem to make them
accessible by only one cluster.
The SET unit_number THIS_PORT_1_ACCESS=FULL/NONE CLI command assigns
specific storage units for access by only one of the two clusters. Each container in the
subsystem must be set up in the manner described in the next section.

Example of CLI Commands
The following examples of command syntax shows the setting of the access to port 1 to
full on both "this controller" and "other controller" for container D100. This is followed
by the syntax to turn on the access to port 2 to full on both "this controller" and "other
controller" for container D200:
Set D100 THIS_PORT_1_ACCESS=FULL
Set D100 THIS_PORT_2_ACCESS=NONE
Set D100 OTHER_PORT_1_ACCESS=FULL
Set D100 OTHER_PORT_2_ACCESS=NONE
Set D200 THIS_PORT_2_ACCESS=FULL
Set D200 THIS_PORT_1_ACCESS=NONE
Set D200 OTHER_PORT_2_ACCESS=FULL
Set D200 OTHER_PORT_1_ACCESS=NONE
These CLI Commands result in cluster A having full access to D100, but D100 is not
available to cluster B. Conversely, cluster B has full access to D200, but D200 is not
available to cluster A.
AlphaServers or GlobalServers (GS60/140/60E) using DWLPB Adapters
The DWLPB-xx hardware option must be at revision F or better before adding HSJ80
Array Controllers to the cluster. The part number is 54-24721-01 rev D.

StorageWorks Command Console Release Notes
The StorageWorks Command Console (SWCC) is a feature-rich graphical user interface
(GUI) for StorageWorks Array Controllers. This section describes the SWCC for the
HSJ80 Client and Agent program modules.
The SWCC Client for the HSJ80 is a graphical user interface that is used along with its
accompanying Agent software. The combination of the two allows the user to configure
and monitor the HSJ80 controller and storage. Its function is similar to that of the HSJ30,
HSJ40, and HSJ50 Storage Window but has new features:
s Two independent CI Host Bus Ports
s Mirrored write-back cache
s Ability to assign unit access to a specific host port
s Support for code load
s HSJ30, HSJ40, and HSJ50 configuration can be saved and restored to an HSJ80

Client Operating Clarifications
Patches Required on OpenVMS 6.2
When running OpenVMS V6.2 (any version), three patches must be installed to avoid
problems with the OpenVMS pthread_delay_np() function. If the patches are not
installed, then problems could occur with the delays not being taken when they should.
Code load failures and lock time-outs occur when this problem is encountered. The three
patches must be installed in the following order:
1. VAXCLUSIO01_062
2. VAXY2K02_062
3. VAXLIBr03_062

CIXCD Host Adapter Firmware Release Notes 13
CIXCD Host Adapter Firmware Release Notes
The CIXCD host bus-adapter for all Alpha CPU and VAX CPU hosts running the XMI
bus, has a new revision of its firmware available. The CIXCD firmware (CIXCD_4K) is
identical to the standard CIXCD firmware except that the maximum packet size has been
increased to 4 KB. This increase allows the HSJ80 to run 4 KB packet data transfers. If
4 KB data transfer packets are desired in your configuration, then you must install this
new firmware revision into all CIXCD host bus adapters in the cluster.
CI Interconnect Support
The CIXCD_4K firmware is supported using standard Computer Interconnect (CI)
configuration rules. The following standard CI node count restrictions also apply to all
CIXCDs running CIXCD_4K:
s Less than or equal to 16 CI host systems
s Less than or equal to 16 CI Hierarchical Storage Controllers
s Less than or equal to 32 CI products or Star Coupler - 16 without the addition of a
Computer Interconnect Star Coupler Extender (CISCE)
s Less than or equal to 96 VMS Cluster member systems
