The cache size requirements for running ACS Version 8.7P or Version 8.7S remain at
512 MB.

Identifying ACS Revision Level

The ACS release package you received should include a PCMCIA program card
containing the new ACS software. Included in this section are instructions for
determining the ACS version running on your RAID Array.

Once ACS is installed, you can identify the specific version of ACS by typing the
following command at the CLI prompt:

HSG80> SHOW THIS_CONTROLLER

6

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

Patching ACS

The resulting display lists the software revision level as one of the following:

V87G

V87F

V87P

V87S

If the ACS version is not Version 8.7 or a subsequently patched version of ACS
Version 8.7, contact your support provider for instructions on how to obtain the
updated version.

If the ACS version is Version 8.7P or Version 8.7S, you need additional layered
application software beyond this Solution Software Kit to take advantage of the added
functionality of these versions. See "Layered Software Applications", page 26, for
additional information on compatible layered application software.

ACS Version 8.7 is fully compatible with Version 8.7A Solution Software. In addition,
Version 8.7A Solution Software is backward compatible with ACS Version 8.6, which
benefits the upgrade process across your SAN.

IMPORTANT: This does not apply to Windows Server 2003. Windows Server 2003 is
compatible with ACS V8.7-1 or higher.

Patching ACS

Each ACS patch builds on the current version of ACS and all previously installed
patches. ACS patches must be installed in order, from lowest to highest, when multiple
patches are installed. ACS patches are available for download from the following
StorageWorks website:

http://h18000.www1.hp.com/products/storageworks/softwaredrivers/acs/index.html

ACS patch downloads come packaged with the instructions and scripts needed to
apply the patch. See the HSG80 Array Controller ACS Version 8.7 Maintenance and
Service Guide for further information on patching ACS.

For multi-bus configurations, use the following procedure in addition to those
provided with the ACS patch download:

1. Apply ACS patches to both controllers.

2. Move all units to

software. Moving the units in this manner is not a requirement, but it lets the
controller do less work than when moving all the units at once.

3. Reboot THIS_CONTROLLER during a slow time (when controllers are running at
more than 50% idle). The patch takes effect once the controller is rebooted.

4. Repeat these steps for

THIS_CONTROLLER and rebooting OTHER_CONTROLLER during a slow time.

ACS Patch Memory

Any installed ACS Version 8.6 (or lower) patches should be removed after an ACS
Version 8.7 installation since they are no longer applicable. This frees up HSG80
patch memory for future ACS patches.

To check or remove ACS patches, run the Code Load and Code Patch utility by typing
the following command:

HSG80> RUN CLCP

Multiple Storage System Types

The extended interoperability of the heterogeneous SAN allows you to mix several
types of StorageWorks storage systems. StorageWorks recommends the following
configuration rules when different storage products are shared in the same SAN:

• HSG80 ACS Version 8.7 and EVA VCS Version 2.0—Use ACS Solution Software
Version 8.7A (includes SWCC Version 2.5) and VCS Version 2.0 compatible
multi-bus software/drivers.

• HSG80 ACS Version 8.6 and EVA VCS Version 2.0—Use ACS Solution Software
Version 8.6 (if SWCC Version 2.4 components are desired) and VCS Version 2.0
compatible multi-bus software/drivers.

• HSG80 ACS Version 8.6 and HSG80 ACS Version 8.7—Use ACS Solution
Software Version 8.7A (includes SWCC Version 2.5).

NOTE: Any multiple storage system configuration that includes EVA VCS Version 2.0 requires
multi-bus support. See "Secure Path Software", page 26, for compatible Secure Path versions.
ACS Version 8.7 compatible Secure Path versions and HBA drivers are compatible with VCS
Version 2.0.

New Features

This section briefly describes new features and changes that are supported by the

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

New Features for 8.7A

The following are major enhancements included in the 8.7A release of the Solution
Software Kit.

• Windows Server 2003—Solution Software Kits now support Windows Server

2003, 32-bit.

• Blade Servers—Solution Software Kits for Windows now support ProLiant

Blade Servers BL20p and BL40p (Windows 2000 and Windows Server 2003
only).

• Secure Path Version—A new version is now supported for both Windows 2000

and Windows Server 2003 and is required for ProLiant Blade Server support but is
not included in this kit.

• Rapid Deployment Pack—Added support for ProLiant Essentials Rapid

Deployment Pack which provides automated server deployment and
redeployment via a central console using imaging and scripting technologies for
ProLiant servers. The deployment console provides simple drag-and-drop
functionality for deployment events. The Solution Software Kit CD-ROM
contains software components, drivers, and utilities that are located in the \rdp
directory. See readme.txt on the CD-ROM for a more detailed description of
Rapid Deployment Pack, installation instructions, and restrictions. For general
information on Rapid Deployment Pack, go to

http://h18013.www1.hp.com/products/servers/management/rdp/index.html

New Features

ACS Feature Enhancements

The following major enhancements are included in the ACS Version 8.7 release:

• Host Connection Table Locking—Host table lock and unlock commands were

added to control the connection table in NVRAM. When the table is locked, the
host login request is rejected (unless the connection is already in the table), and
the request is stored internally on a rejected hosts table.

• Selective Management Presentation—Selective Management Presentation

extends the use of Selective Storage Presentation by providing control over which
SAN Management Agent systems (if any) can perform management operations.

• VENDOR_ID Field—ACS now provides a

Extended information area, returned by the

FULL

commands.

Software Version 8.7A for Windows

9Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

New Features

• Linked WWIDs for Snap and Clone Units—To better manage snap and clone
unit creation, a linked WWID scheme was implemented. It keeps the WWIDs of
these units constant each time they are created. The linked WWID scheme reduces
the number of system data records needed to track unit WWIDs, and enhances the
stability of administrative scripts used in unit creation.

• SMART Error Drive Eject—In prior versions of ACS, SMART error
notifications received from a device were treated as soft (recovered) errors. The
notification was passed to the host and operations continued. ACS now provides a
CLI switch (SMART error eject state) that offers an alternative to this behavior.

With the new switch enabled, drives in a normalized and redundant set that report
a SMART error are removed from that set. SMART errors reported by drives in a
non-redundant or non-normal set continue to be treated as recovered errors. If the
switch is disabled, all SMART errors are treated as recovered errors.

• Error Threshold for Drives—ACS now provides the ability to set limits for drive
errors. Once the limit is reached, the questionable drive is removed from any
redundant set it is a member of and put into the failed set. Errors counted are
medium and recovered errors. Hardware errors are not included in this count since
the drive fails immediately when a hardware error is encountered.

Disk Device Support

This Fibre Channel Solution Software Kit supports the disk devices listed in Table 4 at
the indicated hardware and microcode levels.

NOTE: Full 14-slot drive support per channel is available on MA/EMA Series arrays only.

IMPORTANT: All new Universal SCSI disk drives sold by StorageWorks come with an 8 MB

EISA style partition at the start of the disk. This includes new StorageWorks SBB drives, which
contain the basic universal disk drive brick internally. The EISA partition, when left on the media,
is presented to a host at the storage unit level by the HSG80 storage system. Some hosts and
applications may misinterpret this information. In order to resolve this potential issue,
approximately 8 MB needs to be erased from the beginning of the disk. See "Windows NT
Specific Notes", page 52, for details.

Notes

• HsxDisk.sys and HszDisk.sys are required drivers for array controller
configurations. The Solution Software CD-ROM that came with your kit includes
the following versions of these drivers:

— HszDisk.sys Version 4.4.0.9 for Windows NT 4.0
— HsxDisk.sys Version 5.4.21 for Windows 2000 (used only in transparent

failover configurations)

NOTE: Transparent failover configurations are not supported for Windows Server 2003.

• HS_Service records system errors used in conjunction with remote diagnostics
services provided through Proactive Services software.

• If you see a constantly blinking light on your Fibre Channel Switch, the topology
setting may be set to arbitrated loop mode on your server. To correct this, remove
the existing installation of the Fibre Channel Software and reinstall the desired
setup.

• When upgrading firmware on the DS-KGPSA-BC HBA from Versions 2.x to
Versions 3.x, follow the procedure in "Upgrading DS-KGPSA-BC Firmware",
page 49 of these Release Notes.

StorageWorks Command Console

SWCC Version 2.5 is included in this release. Version 2.5 is used to identify the
SWCC suite of components.

SWCC provides a graphical user interface that can be used to configure and monitor
your storage system. Use of SWCC is highly recommended, but not required. The
SWCC Agent is installed as part of the Solution Software Kit.

24

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

For more information on SWCC installation, see the HSG80 ACS Solution Software
Version 8.7 Installation and Configuration Guide. For more information on SWCC
Client operation, see the Command Console Version 2.5 User Guide and the
Command Console Version 2.5 Release Notes.

SWCC Scalability

• The SWCC Client can monitor up to 128 host systems, each with up to 32 storage

systems, for a maximum of 4096 concurrent storage connections and a total of

2.65 PB of storage.

• One Agent can support up to 32 Clients.

Multiple Agents

This Solution Software Kit contains an SWCC Agent that supports controller locking
during CLI command execution, which allows support for multiple Agents. This
locking feature is required in order to use the Management Appliance in addition to
the host-based SWCC Agent. However, it is not recommended or required to use
multiple Agents for any other purpose.

NOTE: SWCC Agent Version 2.3.2, Build 77 or higher supports the locking feature. This
release of Solution Software exceeds this requirement.

Hardware and Software Support

Multiple Management Sessions

Though multiple clients can be used to monitor your storage system, StorageWorks
recommends that only one instance of storage system management be active at a time.
The client does allow for multiple management sessions, but there are no ownership
rights given to any particular session. Without a highly coordinated effort, multiple
management sessions can undermine the integrity of system maintenance. This same
principle applies to multiple management sessions initiated through the Management
Appliance as well.

SWCC Client Installation

The SWCC client software is installed on your host system from the StorageWorks
Solution Software CD-ROM.

1. Insert the Solution Software CD-ROM into the host system. A menu appears on

your screen.

2. If the program does not start automatically after inserting the CD-ROM, go to the

CD-ROM drive directory and run the

Software Version 8.7A for Windows

launch.exe file.

25Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

ACS Feature Support

ACS Feature Support

The following sections provide details for specific ACS features.

Maximum Host Connections

The maximum number of host connections is 96 for the table of known connections. A
connection is unique to the node WWN, port WWN, and controller port. This table is
maintained in the NVRAM of the controller. If the table contains 96 entries, new
connections cannot be added unless unused entries are deleted. Otherwise, a host
attempting FC login is rejected from becoming a connection into the connection table,
but not necessarily from the fabric.

Rolling Upgrades

This section supersedes both the rolling upgrade and ACS upgrade procedures found
in the HSG80 ACS Solution Software Version 8.7 for Windows NT and Windows 2000

Installation and Configuration Guide.

Operating Constraints

When performing rolling upgrades on the HSG80 array controller, the following rules
and guidelines apply:

Software Version 8.7A for Windows

27Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

ACS Feature Support

• Rolling upgrades must occur in succession. For example, you must upgrade from
V8.6 to V8.7-1.

• If you are performing a rolling upgrade, ensure that the variant for the existing
ACS version being upgraded is the same as that of the next version to be
upgraded. For example, if you want to upgrade ACS V8.6P-10, the ACS version
to be upgraded must be the P variant of ACS V8.7-x.

• You must use a dual-redundant configuration to perform rolling upgrades.

• If you are upgrading the P variant of an applicable ACS version, use the
procedures provided in the hp StorageWorks HSG80 Array Controller Version 8.7
Maintenance and Service Guide. This guide provides specific instructions on
upgrading ACS on the initiator and target site.

• You must upgrade the Solution Software Kit before performing the rolling
upgrade procedure in the “Upgrading ACS” section.

CAUTION: HP StorageWorks Secure Path V3.1A for Windows, Service Pack (SP) 3
or Secure Path V4.0-1 or higher for Windows must be used before performing the
rolling upgrade procedure in the “Upgrading ACS” section. If you don’t, data loss may
occur.

Solution Software Kit Upgrade Procedures

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

ACS Feature Support

NOTE: Solely for the purpose of performing upgrades to ACS, the Solution Software Kit
supports ACS V8.6. HP recommends that you avoid mixing ACS versions in the same Storage
Area Network (SAN).

The extended interoperability of the heterogeneous SAN allows you to mix several
types of StorageWorks storage systems. HP recommends that you adhere to the
following configuration rules when different storage products are shared in the same
SAN:

• HSG80 ACS Version 8.6 and EVA VCS Version 2.0—Use ACS Solution
Software Version 8.6 (if SWCC Version 2.4 components are desired) and VCS
Version 2.0-compatible multi-bus software and drivers.

• HSG80 ACS Version 8.7 and EVA VCS Version 2.0—Use ACS Solution
Software Version 8.7A (includes SWCC Version 2.5) and VCS Version

2.0-compatible multi-bus software/drivers.

• HSG80 ACS Version 8.6 and HSG80 ACS Version 8.7—Use ACS Solution
Software Version 8.7A (includes SWCC Version 2.5).

NOTE: Any multi-bus storage system configuration that includes EVA VCS Version 2.0 requires
multi-bus support. ACS Version 8.7-compatible Secure Path versions on page 26 and HBA
drivers are compatible with VCS 2.0.

See the following documentation for additional information:

• hp StorageWorks HSG80 Array Controller ACS Version 8.7 Maintenance and
Service Guide

• Solution Software Release Notes—HSG80 Enterprise/Modular Storage RAID
Array Fibre Channel Solution Software Version 8.7A for Windows (this document)

• The “Upgrading ACS” section for the additional information on upgrades.

NOTE: If you are upgrading ACS, complete the upgrade after all Windows server updates are
finished. Be sure to back up data before updating servers.

These procedures are applicable to only Secure Path V3.1A for Windows (SP 3) or
Secure Path V4.0-1 or higher for Windows. To obtain Secure Path V3.1A for
Windows (SP 3), visit the HP website at http://www.hp.com

Upgrading ACS

The following subsections provide background and some detailed information
applicable to the HSG80 ACS V8.7-1 Update. HP recommends that you review the hp
StorageWorks HSG80 Array Controller V8.7 Maintenance and Service Guide before
attempting to use the rolling upgrade feature.

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

ACS Feature Support

NOTE: The following rolling upgrade procedures for ACS V8.7-1 (variants F, G, and S) take
precedence over rolling upgrade procedures documented for variants F, G, and S in the hp
StorageWorks HSG80 Array Controller V8.7 Maintenance and Service Guide.

• "Rolling Upgrades", page 27

• "Solution Software Kit Upgrade Procedures", page 28

CAUTION: Failure to follow the recommendations and instructions for the rolling
upgrade feature may result in data loss or system inoperability. See the “Operating
Constraints” section for additional information.

CAUTION: Before attempting the ACS upgrade procedure in the “Rolling Upgrades”
section, verify that the subsystem is in a stable state. The HSG80 array controller
Reset button should be flashing, and all adjacent LEDs should be off (no light). Failure
to perform this verification may result in the loss of data or leave the HSG80 array
controller in an unusable state.

About Rolling Upgrades

There are two ways to upgrade the ACS:

• Using the rolling upgrade procedure—Rolling upgrades take advantage of HSG80

array controller failover capabilities and allow you to upgrade the ACS while I/O
activity continues.

• Using the shutdown upgrade procedure—The shutdown upgrade procedure

requires you to halt I/O activity, shut down your controllers, and dismount your
host systems and any associated units.

NOTE: Shutdown upgrade procedures are documented in the hp StorageWorks HSG80 Array
Controller V8.7 Maintenance and Service Guide that shipped with the HSG80 array controller.

You can download a copy of this guide from the HP website at http://www.hp.com. Follow the
storage-related links to access technical documentation for the HSG80 array controllers, which
are part of the HP StorageWorks Enterprise Modular Array and the HP StorageWorks Modular
Array.

Rolling Upgrade Procedure

The following rolling upgrade procedures for ACS V8.7-1 (variants F, G, and S) take
precedence over rolling upgrade procedures documented for variants F, G, and S in the

ACS Feature Support

To perform a rolling upgrade, complete the following steps. For clarity, the terms
Controller A, Controller B, HSGA>, and HSGB> are used to help you identify which
controller is used.

CAUTION: Attempt a rolling upgrade only when each controller in a dual-redundant
configuration is at least 50% idle. Otherwise, I/Os may be dropped during the upgrade.

1. Connect a PC or terminal to the maintenance port of Controller A, if not already
done.

NOTE: If you have several servers with multiple LUNs in your storage area network (SAN), HP
recommends that you verify that all units are online by using the SHOW UNITS FULL CLI
command. Afterwards, use the Secure Path Manager to move all LUNs to the controller to be
updated last. (LUNs may be removed by either controller.)

2. Verify the utilization percentage for each controller by entering the following RUN
command:

HSGA> RUN VTDPY

The idle percentage for the HSG80 array controller is the first item displayed on
the second line of the VTDPY display. If the HSG80 array controller is less than
50% idle and the screen display indicates activity, the processing load is reduced.
See your operating system documentation for more information on reducing the
processing load.

NOTE: The default VTDPY display refreshes every ten seconds.

3. Repeat step 2 above on the OTHER_CONTROLLER.

Figure 2: Location of the SWCC version number when upgrading from ACS
V8.6 to V8.7-1

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

To verify the correct version of ACS on the HSG80 array controller in this scenario,
always use the SHOW THIS_CONTROLLER or SHOW OTHER_CONTROLLER CLI
command from a CLI window or any CLI prompt.

Disk Partitioning

ACS allows partitioning of disk drives or storagesets for improved device
management. A partition appears to the operating system as a single virtual disk. Up
to eight partitions may be created per storageset or disk drive. Disk partitioning is
supported under all failover modes supported by your operating system.

SNAPSHOT

ACS with SNAPSHOT capability provides a quick and efficient way to make a
point-in-time copy of a storage container’s data. SNAPSHOT freezes a map of the
container’s data, which can be separated and used for backup or testing and
manipulation without having an impact on the original data. After the SNAPSHOT,
the original data can continue to be updated and utilized while the SNAPSHOT copy
remains unchanged.

When the need for the duplicate copy of data has ended, a new snap of a different
storage container can be made and the process repeated. SNAPSHOT eliminates much
of the overhead associated with mirroring and cloning since the SNAPSHOT is
dissolved without having to re-merge the data.

ACS Feature Support

SNAPSHOT is enabled when the following CLI command is entered:

HSG80> ADD SNAPSHOT_UNITS

See the HSG80 Array Controller ACS Version 8.7 CLI Reference Guide for additional
syntax details.

The SNAPSHOT unit can be presented to the host. The SNAPSHOT unit remains
until it is deleted.

NOTE: SNAPSHOT functionality requires either ACS Version 8.7P or ACS Version 8.7S.

IMPORTANT: ACS SNAPSHOT capability requires 512 MB of cache memory.

Write History Logging

Write history logging, available to users of ACS Version 8.7P, uses a log unit to log a
history of write commands and data from the host on the initiator side in either of the
following situations:

• The target is inaccessible.

Software Version 8.7A for Windows

41Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Configuration Rules

• The initiator site data needs to be synchronized during a planned failover.

Mini-merge—If the target becomes inaccessible, the writes that would have gone to
the target are logged to the association set’s assigned log unit. An inaccessible target
in this context refers to both links or target controllers shutting down. When the target
becomes accessible, a full copy is not necessary. Only those host writes that occurred
while the links were down are reissued. This is referred to as a mini-merge. If a full
copy was in progress at the time of the disconnect, write history logging is not
initiated and the full copy is restarted when the target is accessible again.

Fast-Failback—During a planned failover, if write history logging was enabled at the
target site, then when the failback is performed, the initiator site is synchronized
through a process called fast-failback. The writes that would have gone to the initiator
are logged to the association set’s log unit. Only those writes that occurred since the
failover are reissued. A full copy is not necessary.

Dynamic Volume Expansion

Dynamic Volume Expansion creates a specialized volume called a concatset (short for
concatenation set) from a storageset that was given a unit number. Another storageset
can then be added to the concatset by using the
HSG80 Array Controller ACS Version 8.7 CLI Reference Guide for syntax details.

SET CONCATSET command. See the

Dynamic Disks

The use of SNAPSHOTs and SNAPCLONEs in HP SANs is not supported in a
Windows 2000 environment if the SNAPSHOT or SNAPCLONE is presented to the
same Windows 2000 host as the LUN from which the SNAPSHOT or SNAPCLONE
was created. SNAPSHOTs and SNAPCLONEs are features of the HSG80 and
HSV110 controller based HP Storage systems. All Dynamic disks on a system have
information in their metadata about the other dynamic disks that exist on the system.
When Windows is presented with 2 dynamic disks that have the same information on
them, it does not have code to resolve the conflict.

Configuration Rules

The following list defines maximum configuration rules for the controller:

• 128 visible LUNs/200 assignable unit numbers
— In SCSI-2 mode, the CCL is disabled, resulting in 128 visible LUNs.

42

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Windows

SCSI-2 to SCSI-3 Migration

— In SCSI-3 mode, the CCL is enabled, resulting in 127 visible LUNs and one

CCL.

• 1.024 TB storageset size

• 96 host connections

• 84 physical devices

• 20 RAID 3/5 storagesets

• 30 RAID 3/5 and RAID 1 storagesets (see Note)

• 45 RAID 3/5, RAID 1, and RAID 0 storagesets (see Note)

NOTE: For the previous two storageset configurations, this is a combined maximum,
limited to no more than 20 RAID 3/5 storagesets.

• 8 partitions of a storageset or individual disk

• 6 physical devices per RAID 1 storageset (mirrorset)

• 14 physical devices per RAID 3/5 storageset (RAIDset)

• 24 physical devices per RAID 0 storageset (stripeset)

• 45 physical devices per RAID 0+1 storageset (striped mirrorset)

SCSI-2 to SCSI-3 Migration

In order to extend interoperability within the heterogeneous SAN, StorageWorks
highly recommends that customers begin migrating from SCSI-2 to SCSI-3 protocols.
Moving to SCSI-3 allows greater diversity in the operating systems and storage
products (including EVA) that comprise a SAN.

All migrations from SCSI-2 to SCSI-3 should be planned during scheduled downtime.
SCSI migrations require a controller restart and most likely a server restart. Data
contained on CCL units needs to be moved to new units once SCSI migration is
complete.

CAUTION: Before attempting a SCSI-2 to SCSI-3 migration, it is extremely important
that all data be backed up and that units be available for remapping CCL data. In
addition, ensure that all redundant storagesets are in normal (non-reduced) mode.

Software Version 8.7A for Windows

43Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Operating Constraints

When migrating from SCSI-2 to SCSI-3, the controller checks for controller unit D0
and does not change modes until D0 (at all presented offsets) is deleted. One or more
LUNs are lost after the mode change. If you are planning to move from SCSI-2 to
SCSI-3, back up your data first. The data in LUN 0 (and any other offsets that map to
LUN 0) that was used in SCSI-2 requires that the data be moved to a different LUN. It
may be necessary to retrieve this data from a backup.

IMPORTANT: If multi-bus failover configurations or server clustering are employed in the
environment, there may be additional considerations regarding CCL usage during SCSI
migration procedures. Please see your multi-bus failover or server clustering documentation
prior to implementation.

In addition, there may be OS-based limitations on SCSI-3 usage to consider, particularly in
down-level versions of your OS. Please review your OS documentation prior to migration.

For more information, see the “What is the Command Console LUN?” and “Assigning
Unit Numbers Depending on SCSI_VERSION” sections of Chapter 1 in the HSG80
ACS Solution Software Version 8.7 Installation and Configuration Guide.

Operating Constraints

This section describes the operating constraints for ACS Version 8.7. An operating
constraint is a limitation placed on the operation of the controller. Other constraints on
host adapters or other system components may also apply. Keep these constraints in
mind to avoid problems and to help achieve the maximum performance from your
controller. See the documentation that came with your host server for more details.

External Cache Battery

StorageWorks recommends that you replace the External Cache Battery (ECB) every
two years to prevent battery failure.

If you are shutting down your controller for longer than one day, complete the
additional steps in “Shutting Down the Subsystem” in the HSG80 Array Controller
ACS Version 8.7 Maintenance and Service Guide. This prevents the ECB from
discharging during planned power outages.

Dual External Cache Battery Failures

The array controller cache policy provides for proper handling of a single ECB failure
as described in the HSG80 Array Controller ACS Version 8.7 Troubleshooting
Reference Guide. For dual ECB failures, it states that no failover occurs. For this
release, if a dual ECB failure is detected, both controllers are restarted.

Using FRUTIL to Insert a New Controller

When using FRUTIL to insert a new controller in a dual-redundant controller
configuration, you see a new set of instructions after the new controller was inserted:

Software Version 8.7A for Windows

45Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Saving Your Configuration

If the other controller did not restart, follow these steps:

1. Press and hold the Reset button on the other controller.

2. Remove and re-insert the program card for the other controller.

3. Release the Reset button.

NOTE: Whenever you are running FRUTIL you must quiesce all I/O.

FRUTIL Limitation

This limitation applies to users of ACS Version 8.7P with DRM only.
FRUTIL cannot be run in remote copy set environments on the target side specifically

when I/O is in progress.
If the host load was stopped, you can run FRUTIL on the initiator or target. If the host

load is not quiesced and FRUTIL is run while remote copy I/O is running, the
normalization process is reset.

Saving Your Configuration

When enabled, the SAVE_CONFIGURATION function allows you to do the following
(supported on single controller configurations only):

• Save a configuration to a disk or storageset. The configuration may be retrieved
later and downloaded onto a replacement controller.

• Retain code patches to the ACS software.

Saving a Configuration to Previously Initialized Storagesets

If any storageset within the configuration was previously initialized with the

INITIALIZE container-name SAVE_CONFIGURATION command to save your

configuration to disk, it is not necessary to reconfigure your devices with a new
controller.
This option is supported on single controller configurations only.

ACS Version 8.7 saves any installed software patches on disks initialized with the

SAVE_CONFIGURATION command. To replace a controller and restore the configuration

from a disk, you do not have to reinstall any software patches.
Configuration information cannot be retrieved from storagesets created on other HSx

controllers (for example, HSD, HSJ, or HSZ controllers). You can only restore a
configuration from a configuration saved on this or another HSG80 array controller.

46

SAVE_CONFIGURATION also retains code patch information to the software.

Software Version 8.7A for Windows

Avoiding Problem Situations

Under certain conditions, you may experience unusual array controller behavior. This
section presents information to help you avoid such situations and to recover from
them if they occur.

Adding, Moving, and Changing Devices

The array controller maintains a configuration map of device types and locations. This
map is used to communicate with devices. If you add, move, or change a device while
the array controller is powered off without first changing the array controller
configuration, the array controller is not able to communicate with the changed device
when it returns to service.

If a device is removed by mistake while the array controller is off, delete all containers
associated with the removed device after power was restored to the array controller.

If a device is replaced while the array controller is off, install the replacement device
before restoring power to the array controller. Once power is restored, use the

DELETE DISK CLI command to remove the disk from the configuration. Then use the
ADD DISK CLI command to add the new device. This correctly removes the failed

device and adds the new device after restoring power to the array controller.

Avoiding Problem Situations

See the HSG80 Array Controller ACS Version 8.7 CLI Reference Guide for details on
CLI command usage and syntax.

See the HSG80 Array Controller ACS Version 8.7 Maintenance and Service Guide for
correct device removal and addition procedures.

Moving Storagesets

Move only normal storagesets. Do not move storagesets that are reconstructing or
were reduced.

CAUTION: Ensure all storagesets are in normal mode prior to moving them, or data
corruption occurs.

Replacing Array Controllers, Cache Modules, or External Cache Battery Storage Building Blocks

You can replace the array controller, cache module, or external cache battery (ECB)
storage building block (SBB) while the storage system is shut down. However, you
must enter the

SHUTDOWN THIS_CONTROLLER command prior to shutting down the

storage system in order to make configuration changes. If two array controllers are
configured in a dual-redundant configuration, you must first enter the

SHUTDOWN OTHER_CONTROLLER command.

These commands instruct the array controllers to flush all unwritten data from the
cache modules and discontinue all I/O activity. For more information regarding the

SHUTDOWN controller command, see the HSG80 Array Controller ACS Version 8.7 CLI

Reference Guide. For information on maintenance and replacement of the array
controller, cache module, and external cache battery, see the HSG80 Array Controller
ACS Version 8.7 Maintenance and Service Guide.

Disk Resource Pending Timeout for Large Configurations

In order to ensure continuous operation of Disk Resources across SAN perturbations
with Disk Resource counts greater than eight, it is recommended that the Pending
Timeout parameter for each Disk Resource be increased from 180 seconds to 360
seconds.

To view and set the Pending Timeout parameter:

1. Open the Microsoft Cluster Administrator.

2. Select a Disk Group resource in the left pane.

3. Right click each Disk Resource in right pane, one at a time, and select Properties.

4. Select the Advanced tab from the Properties menu.

5. Locate the Pending Timeout value and change it to 360.

6. Click OK.

Unit Offsets

Setting unit offsets requires a host reboot for the newly set offsets to take effect.

Host Operating System Notes

SWCC SCSI Connection

The SWCC Client SCSI connection can sometimes produce the following error
message when trying to connect through the CCL:

Error scanning subsystem. Command Execution Error: [DeviceIOControl
Error:]

Additionally, physical devices may not appear in the Select Device drop-down list.
The SWCC CLI Window terminates if the New Window icon is selected, or if New is
selected from the File Menu, followed by clicking the Cancel button on the
Connection Selection dialog box. If the connection becomes lost, restart the Client
application.

StorageWorks strongly recommends that you use the SWCC Agent to manage the
storage system.

Host Operating System Notes

The following section lists host-specific operating notes.

Host Operating System Support of Multi-Bus Failover

Multi-bus failover is supported on the Windows NT, Windows 2000, and Windows
Server 2003 operating system through the use of Secure Path software. See "Secure
Path Software", page 26, for version compatibility and restrictions.

Upgrading DS-KGPSA-BC Firmware

Use this procedure to upgrade the DS-KGPSA-BC HBA firmware from Version 2.x to
Version 3.x (for example, V2.20x7 to V3.20x7).

Version 3.x firmware is Fibre Channel Standard compliant and uses a different World
Wide Name (WWN) for Host and Port (2xxx-xxxx-xxxx-xxxx format for Host and
1xxx-xxxx-xxxx-xxxx for Port, where xxx-xxxx-xxxx-xxxx is identical in both).

The new WWN structure creates new Host Connections on the HSG80 controllers for
the HBA. The original host connections are marked “offline” and are no longer usable.

To maintain server access to storage units behind the HSG80 controllers, change the
storage units’ access to use the new Host Connections.

Software Version 8.7A for Windows

Windows NT, Windows 2000, and Windows Server 2003

• Windows NT, Windows 2000, and Windows Server 2003 can run MSCS software.

See documents that come with Microsoft's software kits for instructions on setting
up Microsoft clusters.

• There is no Hot Plug support for FC HBAs under Windows NT 4.0, Windows

2000, and Windows Server 2003 at this time. Check the StorageWorks Support
website for updates.

• Windows NT and Windows 2000 support SCSI-2 and SCSI-3 modes. See the

HSG80 ACS Solution Software Version 8.7 Installation and Configuration Guide
that comes with this kit for more information.

Software Version 8.7A for Windows

51Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Host Operating System Notes

• StorageWorks recommends that you load software directly from the Solution
Software CD-ROM when installing drivers and running the Fibre Channel Setup
utility. You may experience problems on some systems if you first copy the
CD-ROM contents to a disk drive and then install from there.

• Windows 2000 dynamic volumes are supported in transparent failover
configurations or in Secure Path Version 4.0x multi-bus configurations.

• Cloning a Windows 2000 dynamic disk is allowed. However, either the CLONE
or the original can be mounted to the same host but not both.

Windows NT Specific Notes

• Fibre Channel software setup handles HszDisk and HS_Service installation. This
is sometimes referred to as HSZinstall in the documentation.

IMPORTANT: Do not use the Large LUN model with Windows NT Service Pack 5 under
any circumstances. Windows NT Service Pack 6A is the stated minimum for this Solution
Software.

• In a situation where you are replacing a server with another and using the existing
drives (storagesets) behind the array controllers, you may find drive to drive letter
mapping changes. During such a system changeover, remap drives to drive letters
using the Disk Administrator to restore proper access to your data.

• To delete the 8 MB EISA-type partition on new disk drives, as discussed in the
"Disk Device Support", page 18, create a unit and delete the partition in Disk
Administrator.

Windows 2000 Specific Notes

• New Universal Disk Drives (or units that are migrated from SmartArray
controllers usage) being configured into storageset members need to be initially
written to with DILX (a diagnostic utility on the HSG storage systems). DILX
only operates on units. Therefore, the new disks must be configured into a unit
prior to running DILX. Optionally, the HSUTIL format disk utility may be used
on a disk device.

• The Fibre Channel Setup utility installs HS_Service and HsxDisk software
components. These are similar to HS_Service and HszDisk in the Windows NT
setup procedure.

• There are two situations in which drive-letter remapping might occur and that
could affect access to data by programs you may need to run. The first situation is
one in which you replace one server with another. The second is a situation in

Software Version 8.7A for Windows

Host Operating System Notes

which you simply replace an FC HBA in one of your systems. During such a
system or adapter changeover, be sure to manually remap drives to drive letters
using Disk Manager. This restores proper access to your data.

• If you replace an FC HBA in a server, you need to reinstall the HBA driver and

then rerun the Fibre Channel Setup utility. This is so that Windows 2000 can
automatically reload the original driver for this adapter and reset many of the
important registry settings. New connections are created on the HSG controller.
Those connections should be renamed and assigned to the appropriate units.

For more information about installing the adapter, see the HSG80 ACS Solution
Software Version 8.7 Installation and Configuration Guide and use the software
on the Solution Software CD-ROM.

Upgrading from Windows NT 4.0 to Windows 2000 or Windows Server 2003

If you are upgrading from Windows NT 4.0 to Windows 2000 or Windows Server
2003, you must remove the software components installed by the previous version of
the Fibre Channel Setup utility. Follow these steps:

1. Remove the software components installed from the previous Fibre Channel Setup

utility. To do this, locate the previous CD-ROM and run the utility. Follow the
procedures in it to remove components. Alternately, you can use the Add/Remove
Programs applet.

2. Upgrade from Windows NT 4.0 to Windows 2000 or Windows Server 2003 as

instructed by Microsoft's documentation.

3. Reboot.

4. Install the HBA driver upgrade as instructed in the HSG80 ACS Solution Software

Version 8.7 Installation and Configuration Guide.

5. Run the Fibre Channel Setup utility to complete your installation.

ResetTPRLO Parameter in Windows Environments

All Windows SAN installations require the ResetTPRLO (Third Party Logout
Extended Link Service) HBA driver parameter be set to a value of 1. When HBA
driver Version x-4.53a7 or higher is installed, this parameter must be changed from the
default value, which is set to 0.

Software Version 8.7A for Windows

53Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Host Operating System Notes

For HBA driver versions above Version x-4.53a7, this value is set automatically by the
Fibre Channel Software Setup included in this release of Solution Software.

For HBA driver Version x-4.53a7, this parameter must be set manually. For all
Windows configurations using this driver version, verify that the ResetTPRLO HBA
driver parameter is set to 1 by using the LPUTILNT utility. Use the following
procedure:

1. Choose Start and then Run.

2. Type

LPUTILNT and select the first HBA.

3. Select Driver Parameters in the Category pane.

4. Click Parameters.

5. Scroll down and double-click ResetTPRLO.

6. Set the value to 1.

7. Select Permanent and Global.

8. Click Change.

You need to follow this procedure for each HBA that uses Version x-4.53a7 drivers in
the system. If you use this method, you do not have to restart Windows after the
registry is modified. The ResetTPRLO parameter is dynamic.

See Customer Advisory OI020510_CW0x for additional information.

Registry Growth in Windows

The Windows plug-and-play architecture has a limitation on the number of
plug-and-play device entries that can be added to the registry. Whenever devices are
added or removed, or SNAPSHOT is created or deleted, entries are added to the
registry by the Plug-and-Play manager, potentially causing the registry to grow
beyond the allowed capacity.

If more than 700 entries are in the registry, the next time the system reboots for any
reason, the following error message occurs before the operating system boots up:

“Failed to load Windows 2000 due to a file missing or corrupt in the
\WINNT\SYSTEM32\CONFIG\SYSTEM directory.”

Please see the Microsoft Knowledge Base article (Q269075), which provides more
information about the registry growth problem.

Host Operating System Notes

Large LUNs for Windows NT and Windows 2000

Enabling Large LUNs allows a Windows NT or Windows 2000 server to have access
to LUNs beyond the 0-7 range, and to access more than 8 LUNs per target. The host
can access unit D10 by leaving the connection offset at 0.

The maximum number of LUNs supported is 256 per storage system. If using Secure
Path Version 3.1A SP1, the maximum number of LUNs is 64 per storage system. If
using Secure Path Version 4.0x, the maximum number of LUNs is 256 per storage
system. The LUNs can be contiguous or non contiguous.

NOTE: Large LUNs are supported on Windows NT, Windows 2000 Server, and Windows 2000
Advanced Server.

Large LUN Utility for Windows

The Large LUN utility is available for download at the StorageWorks website:

http://h18006.www1.hp.com/storage/index.html

NOTE: The Large LUN utility is unnecessary if ACS Version 8.6 or higher is running alone or in
conjunction with Secure Path software, which has built-in support.

Controller Configuration

It is recommended that you set the SCSI_VERSION to SCSI-3 for maximum
availability.

• Multi-bus failover mode (with Secure Path Version 3.1A SP1)—Support for 64

LUNs per storage system (SCSI-2 mode) or 63 LUNs + 1 CCL (SCSI-3). These
LUN numbers must be between 0 and 63.

• Multi-bus failover mode (with Secure Path Version 4.0x)—Support for 128 LUNs

per storage system (SCSI-2 mode) or 127 LUNs + 1 CCL (SCSI-3). These LUN
numbers must be between 0 and 199.

• Transparent failover mode—Support for 128 LUNs per storage system (SCSI-2

mode) or 127 LUNs + 1 CCL (SCSI-3). These LUN numbers must be between 0
and 199.
