The contents of the Recovery Server Option /U kit are illustrated in
Figure 1-2. When implementing OSCRO, not all of the parts in the kit will
be needed. Those that are not needed for OSCRO are shaded in the figure.
To implement OSCRO, you may also need one or more additional internal
SCSI ribbon cables (part number 199595-002). These are the original cables
that came with your SMART-2 Array Controllers. If you do not have the
correct cables and you are planning a dual-channel configuration (see
Chapter 2), you also need one or more Spares kits (part number 198639-
001). Spares kits include the required ribbon cable, screws, and screwlocks
required for OSCRO implementation.
Verify that you have all the necessary items before beginning the installation.

Chapter 2
Functionality and Configuration
Options
There are three high-availability option solutions in the Recovery Server
Option /U kit:
■ Standby Recovery Server
■ On-Line Recovery Server
■ Online Storage Controller Recovery Option (OSCRO)
The first two option solutions minimize server downtime by automatically
transferring operations from a failed server to a backup server.
OSCRO, on the other hand, provides a way to reduce or eliminate downtime
associated with mass storage controller failure. In this chapter, we examine how
OSCRO provides this benefit.
Redundancy at the Mass Storage
Controller Level
In the past, the effort to improve the reliability of I/O subsystems focused on
redundant arrays of independent disks (RAID). RAID protects data if a disk
drive fails but offers no protection against mass storage controller failure.
Windows NT provides the option to implement a fully redundant I/O subsystem
in a configuration called Disk Duplexing. Disk Duplexing implemented at the
software level provides protection against failure of the disk as well as the mass
storage controller. Disk Duplexing requires complete redundancy of all I/O
subsystem components, however, which makes it very costly to implement and
limits the extensibility of the system.
With the introduction of OSCRO and its two-way switching capability,
Compaq offers fault tolerance for mass storage controllers implemented at the
hardware level, providing increased reliability without the need for complete
I/O subsystem redundancy.

Functionality and Configuration Options
Merging two SMART-2 Controllers
into a Controlled Pair
OSCRO allows you to merge two matched SMART-2 controllers into a
controller pair. In such a pair, one controller is active and the other remains
in standby mode. Should a problem occur with the active controller, the
SMART-2 device driver switches traffic to the standby controller without
loss of data or interruption of service (see Figure 2-1).

2-3
Previously, implementing mass storage controller redundancy required
duplication of the mass storage controllers, as well as the disk drives. By
pairing OSCRO with RAID 5 arrays, you gain the benefits of fault tolerance for
the disks and the controllers without the additional costs of complete disk drive
redundancy.
OSCRO extends the reliability of Windows NT servers by ensuring continuing
operation of the system, even when a mass storage controller fails. The Compaq
Online Storage Controller Recovery Utility for Windows NT provides a means
of managing the mass storage controllers of the entire Windows NT network
from a single management station.
OSCRO is a natural partner for Compaq PCI Hot Plug technology. The
combination of the two eliminates the need to shut the system down when a
mass storage controller fails. OSCRO permits the system to continue operating
after a controller failure, and PCI Hot Plug technology allows replacement of
the failed controller without shutting the system down.

SMART-2 Array Controllers implement RAID fault tolerance at the hardware
level, eliminating the overhead associated with implementing RAID in the
software. Another advantage of implementing RAID at the hardware level is
the ability to apply any of the RAID configuration options to the system disk, as
indicated in Table 2-2.

Using OSCRO with RAID 0 provides protection against failure of a SMART-2
Array Controller, but does not provide any data protection if a disk fails.

Functionality and Configuration Options
The combination of OSCRO and RAID 1 provides all the advantages of
traditional disk duplexing. This combination provides the additional advantage
of implementing all the fault tolerance features at the hardware level, thus
eliminating the overhead associated with implementing fault tolerance in the
software.
Pairing redundant SMART-2 Array Controllers with RAID 5 disk arrays
provides the data protection of the RAID implementation and the fault tolerance
of redundant controllers.
Conceptually, there are two ways to configure an OSCRO implementation:
single channel and dual channel. OSCRO can also be set up in more complex
combinations of single-channel and/or dual-channel configurations.
Single-Channel Configuration
The simplest OSCRO configuration involves two SMART-2 Array Controllers
and a single ProLiant Storage System/F or /U equipped with the Recovery
Server Switch. The Compaq Online Storage Controller Recovery Utility is used
to merge the independent controllers into a controller pair. One controller is the
active controller, and the other is designated the standby controller. Both
controllers are physically wired to the ProLiant Storage System/F or /U through
the Recovery Server Switch, as illustrated in Figure 2-2.
Any two SMART-2 controllers with the same channel count can be used to
form a basic controller pair. When using a single-channel controller, such as the
SMART-2SL, the single-channel configuration is the only feasible OSCRO
configuration.
IMPORTANT:
installed from an earlier version of the Recovery Server Option kit, you must
disable that option, upgrade the Recovery Server Switch in the ProLiant
Storage System/F or /U, and reconfigure the cabling in order to implement
OSCRO. RSO and OSCRO cannot be implemented in the same devices at the
same time.
If you already have the Recovery Server Option (RSO)

Single Controller Pair Configuration -- Logical Diagram
The single-channel configuration provides the foundation for understanding
how to configure OSCRO. Note that in the example shown in Figure 2-2, the
active controller is connected to the primary port on the ProLiant Storage
System.
The active controller should always be connected to the primary port of the
ProLiant Storage System to provide consistent recovery after complete power
loss to the server and the storage system. When the power is cycled on the
ProLiant Storage System, the Recovery Server Switch inside is reset and the
primary port becomes the active port by default. By aligning the primary port of
the ProLiant Storage System with the active controller of the controller pair, the
system recovers from a power failure using the power-up defaults.

Functionality and Configuration Options
This configuration rule is especially significant when the system boot device is
connected to a controller pair. Because the boot device controller is selected
during System Configuration by setting the Controller Order to First, no other
controller can be used to boot the system. Therefore, the boot device controller
must be given default access to the ProLiant Storage System after power is
restored.
Dual-Channel Configuration
Dual-channel SMART-2 Array Controllers are capable of supporting two
ProLiant Storage Systems. A controller pair can support a pair of ProLiant
Storage Systems as long as the cabling is done properly. Figure 2-3 shows a
logical diagram of such a configuration.
When forming dual-channel controller pairs, both controllers must be dualchannel controllers. Do not attempt to use single-channel controllers such as the
SMART-2SL in a dual-channel configuration.

Multiple Controller Pairs
An OSCRO multiple controller pair configuration would be required in an
installation that needs mass storage controller redundancy for more than 14
spindles of data. A controller pair in a multiple controller pair configuration
can be a single-channel or dual-channel pair. The capability to define multiple
controller pairs extends the configurable size of the fault-tolerant I/O
subsystem. With increased flexibility comes an increased need for planning
and care during configuration and installation.

2-10
Functionality and Configuration Options
The number of possible controller pairs may be limited by the number of
knockout panels or slots (see Figure 3-6) available on the server as well as the
number of available expansion slots for SMART-2 controllers. Some older
ProSignia servers have only one knockout panel with four slots. Such systems
are limited to implementing two dual-channel configurations.
NOTE
: Newer ProLiant servers have knockout slots built in to the case and do not
require installation of the knockout panel assembly.
Internal vs. External Boot Device
OSCRO implementation does not require you to include the boot device
controller in an OSCRO controller pair. There are advantages to doing so, and
there are advantages to not doing so.
Having the operating system on a drive protected by an OSCRO controller pair
protects the operating system as well as the data on the disks. There are,
however, boot device considerations with OSCRO. For a discussion of these,
see the “Boot Device Configuration Planning” section in Chapter 3.
One way to improve performance is to segregate system I/O traffic from
application I/O traffic. This can be achieved by creating a separate OSCRO
controller pair for the boot device controller, or by leaving the boot device
controller as a standalone device. When the embedded SCSI controller is used
as the boot device controller, segregation of I/O traffic is achieved, but OSCRO
does not allow use of the embedded SCSI controller in a controller pair.

Chapter 3
Planning and Installing the
Online Storage Controller
Recovery Option
To implement OSCRO, you must perform some or all of the following planning
and installation steps:
1. Plan the hardware configuration, taking related issues into account.
2. Install new controllers, if necessary. Minimally, you should label the cables
you will use for OSCRO and connect them based on the OSCRO
configuration you have selected.
3. Upgrade the SMART-2 controller firmware and device drivers.
4. Load the OSCRO software.
5. Use the Compaq Online Storage Controller Recovery Utility to merge
controllers in OSCRO controller pairs.
Hardware Planning
The first step toward OSCRO implementation is hardware planning. You must
have at least one Compaq ProLiant or ProSignia server, at least two
SMART-2 Array Controllers of the same type, and at least one Compaq
ProLiant Storage System/F or /U.
Controllers for OSCRO Implementation
There are two types of SMART-2 Array Controllers that can be made into
OSCRO redundant controller pairs. They are:
■ Single channel (SMART-2SL)
■ Dual channel (SMART-2/P, SMART-2/E, SMART-2DH)

3-2
Planning and Installing the Online Storage Controller
CAUTION: SMART-2 Array Controllers use different disk geometries than
standard SCSI adapters. Consequently, disks cannot be interchanged
between SCSI adapters and SMART-2 Array Controllers without complete
loss of data on the disk.
Dual-Channel Configuration Considerations
You may want to consider a dual-channel OSCRO configuration when you
want mass storage controller redundancy for more than seven spindles of data.
There are a few things you should consider when planning for a dual-channel
OSCRO configuration or a multiple controller pair configuration that involves a
dual-channel controller pair. They are:
1. When forming dual-channel controller pairs, both controllers must be
dual-channel controllers. Do not attempt to use a single-channel
controller, such as the SMART-2SL, in a dual-channel configuration.
2. You may need a knockout panel(s) (see Figure 3-6) on the back of the
server where the External Wide SCSI connectors will be mounted. If the
knockout panel has no slots, you can replace it with the knockout panel
included in the Recovery Server Option /U kit. Newer ProLiant servers
are equipped with knockout slots and thus do not require knockout panel
installation
Knockout Panels
The number of possible controller pairs in your OSCRO implementation may
be limited by the number of knockout panels or slots available on the server.
Some older ProSignia servers have only one knockout panel with four slots.
Such systems are limited to implementing two dual-channel OSCRO
configurations. Some servers have integrated knockout slots rather than
knockout panels.
IMPORTANT: Some older ProSignia systems do not have any knockout
panels and cannot be used in dual-channel OSCRO implementations.

3-3
OSCRO Planning Implications
There are several things to consider before installing OSCRO. They include
thinking about your current environment in terms of the following:
■ The Recovery Server Option /U kit contains parts for three different
high-availability option solutions. Because these are mutually exclusive
options, if you are going to implement OSCRO and you already have
either Standby Recovery Server or On-Line Recovery Server installed
on your existing server, you need to de-install the Recovery Server
Option now in place.
■ If you have a duplexed ProLiant Storage System/F or /U, you may not
want to implement OSCRO, because OSCRO does not support duplexed
storage systems. If you decide to implement OSCRO, you will need to
de-install the duplexed ProLiant Storage System and potentially rebuild
all of your disk arrays and logical drives.
■ If you have an older ProLiant Storage System, you need to upgrade to
the ProLiant Storage System/F or /U.
■ For each upgrade of Windows NT or device drivers, the OSCRO
controller pairs must be dissolved before the upgrade, and re-established
after the upgrade is completed.
Upgrading controllers requires dissolving and re-merging OSCRO controller
pairs only when you are upgrading the device drivers or switching from
single-channel to dual-channel controllers. Upgrading from SMART-2/P to
SMART-2DH, for example, has no direct impact on an OSCRO controller
pair. Moving controllers to different PCI or EISA slots, on the other hand,
requires dissolving and re-merging a controller pair.

Planning and Installing the Online Storage Controller
Potential Impact on Unattended Reboot
Installation of OSCRO effectively sets up a standby mass storage controller.
Consequently, in an OSCRO implementation, at least one of the SMART-2
Array Controllers on the system is not electrically connected to the ProLiant
Storage System at boot time. This condition, which is detected during Power
On Self Test (POST), causes the system to prompt for the system administrator
to press F1 to continue or F10 to run system partition utilities. Because this
prompt does not time out, unattended reboots may be inhibited.
To facilitate unattended reboots, disable the F1 Boot Prompt using the System
Configuration Utility before OSCRO is installed. For detailed instruction on
how to do this, see the “Installing the Controllers” section later on in this
chapter. It is also recommended that you retain the bootable System
Configuration disk to facilitate subsequent configuration changes.
Boot Device Configuration Planning
Connecting the boot device to a controller pair requires careful planning. Only
the primary mass storage controller, designated First in Controller Order by
the System Configuration Utility, can act as the boot device controller.
When configuring a boot device in an OSCRO controller pair, keep in mind
that:
■ The primary mass storage controller must be the active controller of the
controller pair at boot time.
■ The primary mass storage controller must be connected to the port of the
ProLiant Storage System/F or /U that activates immediately after
powering up the ProLiant Storage System. In a tower system, this is the
top port; in a rack-mount, it is the left port as you face the back of the
system.
This configuration provides fault tolerance for the boot device controller, which
enables the server to continue operating even if the primary mass storage
controller fails.
Page 33
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
3-5
Array Acceleration Disabled
To ensure data integrity in the event of controller failure, implementing
OSCRO automatically disables the Array Accelerator feature of the SMART-2
Array Controller. This preserves coherency between the controllers in case of a
failovera switch from the active (failed) controller to the standby controller.
Under no circumstances should array acceleration be enabled on a SMART-2
Array Controller that is a member of an OSCRO controller pair.
The system performance implications of disabling the array accelerator vary
according to the application type and load placed on the system.
Recovery Server Option Incompatibility
Compaq Recovery Server Option consists of the Standby Recovery Server and
the On-Line Recovery Server. OSCRO cannot be run in conjunction with either
Recovery Server Option because both require hardware connectivity to
ProLiant Storage Systems through the same interfaces and, although the cables
are the same type, the cabling requirements are not compatible.
Setting Up for OSCRO Installation
There are several tasks that need to be accomplished to fully implement the
Online Storage Controller Recovery Option. They include:
1. Installing the Recovery Server Switch in the ProLiant Storage System/F
or /U
2. Upgrading the SMART-2 Array Controller firmware
3. Updating the SMART-2 device drivers
4. Loading the OSCRO software from the Compaq Support Software for
Microsoft Windows NT (SSD)

Planning and Installing the Online Storage Controller
These tasks, which should be performed in the order presented, are described in
this section. You will need diskettes for step 2. Steps 3 and 4 can be done
directly from the SmartStart and Support Software CD. If you do not have the
diskettes required for Step 2, see Appendix C, “Building Diskettes from the
SmartStart and Support Software CD,” for instructions on how to create them.
Installing the Recovery Server Switch in the
ProLiant Storage System/F or /U
The Recovery Server Switch must be installed in the ProLiant Storage
System/F or /U that will be controlled by an OSCRO pair. The switch fits in
either a tower or rack-mount ProLiant Storage System/F or /U. Installation
differs, as described in the next sections.
Switch Installation in a Tower
To install the Recovery Server Switch in a tower ProLiant Storage System/F
or /U:
1. Make sure the power switch on the ProLiant Storage System is turned off.
2. Looking at the back of the ProLiant Storage System/F or /U, locate the
Fast-Wide SCSI interface module. Press the release tabs and remove the

■ Installing the OSCRO software
■ Making one or more controller pairs
If the controllers you will be using for OSCRO are already installed and
configured, go to the next section, “Labeling the Cables.”
Installing the Controllers
The SMART-2 Array Controllers must be installed and configured using the
Array Configuration Utility. For additional information, refer to the SMART-2
Array Controller Installation Guide that came with the controllers you will be
using for OSCRO.
To install SMART-2 Array Controllers:
1. Back up the entire data environment of the server.
2. Shut down Windows NT, and power down the server.
3. Insert the SMART-2 controller(s) necessary for your OSCRO
configuration into available PCI slot(s).
4. Power up the system.
5. Boot the system into the System Configuration Utility (version 2.34A or
above) using the System Configuration diskette built from the SmartStart
and Support Software CD included in the kit. If you do not have the
diskettes required for this step, see Appendix C, “Building Diskettes from
the SmartStart and Support Software CD,” for instructions on how to create
them.
6. Disable the F1 Boot Prompt using the Advanced Mode of the System
Configuration Utility by performing these steps:
❏ After passing through the initial screen(s), the Main Menu is
displayed. Press Ctrl + A. A notice pops up stating that Advanced

Merging Two Controllers into a Controller Pair
To make a controller pair:
1. Access the Compaq Online Storage Controller Recovery Utility by
double-clicking the Compaq Online Storage Recovery applet in the
Control Panel, or in the Compaq System Tools folder.
2. Confirm that the controllers you want to merge are properly connected
to the ProLiant Storage System using theRecovery Server Switch. While
verifying the connection, make note of the physical slot number of the
controllers connected to the ProLiant Storage System. This eliminates
any possible confusion when performing the merge operation.
3. When you are certain the connections are correct, select one of the two
controllers by clicking it. Hold down the Ctrl key and click the second
controller you want to be part of the pair. Doing so highlights both
selected controllers and activates the Merge button, as shown in
Figure 3-9.

Testing and Verifying the Installation
The last step of the OSCRO installation is to perform a Verify function on each
controller pairif you have not already done so. To Verify an OSCRO
controller pair, perform these steps:
1. Right-click the controller pair (the line with the white icon on the left), and
select Verify.
2. In a minute and a half or so, you either see a controller marked with a red
X (indicating failure) or the screen returns to its normal state (indicating
success).

3. If failure is indicated, make sure the cables are all attached and correctly
configured, then rerun the Verify process.
The Verify function in the Compaq Online Storage Controller Recovery Utility
takes over 80 seconds. During this process, all three icons have yellow X’s over
them indicating the controllers and the pair are Not Ready for use. As the test
progresses, each yellow X is removed, indicating that the configuration has
been deemed valid, or one or more yellow Xs are replaced by a red X,
indicating a cable fault. When the test concludes, the primary controller is
returned to active status.
IMPORTANT: If your configuration does not Verify and/or does not look
like one of the configurations described in Chapter 2, see Chapter 5,
“Troubleshooting.”

Compaq Online Storage
Controller Recovery Utility
The Compaq Online Storage Controller Recovery Utility is used to manage
OSCRO controller pairs.
This utility can be accessed from the Compaq Online Storage Recovery
applet in either the Control Panel or the Compaq System Tools folder. Each
SMART-2 Array Controller is displayed showing its controller type and its
physical location. The color of the icon indicates whether it is part of a
controller pair.
The Compaq Online Storage Controller Utility includes a browser that allows
you to configure and manage the mass storage controllers on the entire network
from a single management station. This browser works like the Network
Neighborhood function of Windows NT.
Major Functions
The primary functions of the Compaq Online Storage Controller Recovery
Utility are Merge, Dissolve, Properties, Browse, Refresh, and Help.
Merge combines two like controllers into an OSCRO controller pair.
Dissolve splits an OSCRO controller pair into two independent controllers.
Properties provides detailed information about controllers.
Browse locates other systems on the network and allows you to manage them
remotely. You must have a privileged account on the remote node in order to
manage the mass storage controllers on that system.
Refresh forces the main screen of the Compaq Online Storage Controller
Recovery Utility to update its information display.
Help provides online help on use of the Compaq Online Storage Controller
Recovery Utility and configuring OSCRO controller pairs.

Right-Click Functionality
In addition to the primary functions, the Compaq Online Storage Controller
Recovery Utility provides several secondary functions that are available by
right-clicking the mouse button on a selected controller or controller pair.
Figure 4-1.
Figure 4-2.
As shown in Figures 4-1 and 4-2, the specific functions offered by the rightclick depend on whether the highlighted device is a controller or a controller
pair. The functions available for a controller are Fail/Unfail, Merge, and
Properties.
Fail / Unfail can be used to manually fail or unfail a controller.
Merge combines two like controllers into a controller pair. This is the
functional equivalent of the Merge button on the screen. This function is only
available when you highlight two controllers.

Properties provides detailed information abut an individual controller. This
function is not available when a controller pair is selected. More detail of this
function is given in the “Viewing Device Properties” section below.
The functions available on a controller pair are Dissolve, Switch, and Verify.
Dissolve splits an OSCRO controller pair into two independent controllers.
This is the functional equivalent of the Dissolve button on the screen.
Switch performs a manual switch, promoting the standby controller of a
controller pair to active status. This function provides a way to switch which
controller is active.
Verify performs two Switch operations in order to verify that both controllers
of the controller pair are capable of becoming active, and that the cables are
physically connected.

When a controller pair is formed, a new icon representing the union of the two
individual controllers is displayed.
The normal controller pair icon is white. When a controller fails, the white icon
is covered with a red X. If there is no power to either controller in the pair, the
icon is black. If both controllers are failed or one is failed and the other has no
power, a white icon appears with a red X over it. If one of the controllers is not
ready or failed (this is the state during a Verify), the white icon for the pair is
covered with a yellow X. You also see a yellow X if one of the controllers in a
pair requires action to get OSCRO to a ready state.

Troubleshooting
If you are unable to perform a task associated with OSCRO, make sure you
have the privilege associated with the task. Other problems you encounter may
relate to reconfigured hardware or upgrading software related to OSCRO,
including Windows NT itself.
Controllers Must Be Matched
Setting up OSCRO requires that both members of a controller pair are capable
of sharing a single instance of the device driver. For this reason, the Online
Storage Controller Recovery Utility does not allow you to create a mismatched
controller pair.
Planning for OSCRO when RSO is in Use
Because the Standby Recovery Server, On-Line Recovery Server, and OSCRO
are mutually exclusive option solutions, an invalid configuration results from
implementing OSCRO when one of the other Recovery Server Options has
been installed and has not been de-installed.
It is also important to understand that the cabling for the Standby Recovery
Server and On-Line Recovery Server options is incompatible with OSCRO.
The cables are the same type but they must be reconfigured for OSCRO. If the
system already has one of the Recovery Server Options installed, you must
reconfigure the cabling before implementing OSCRO.
Incorrect Cabling
There are several ways to cable OSCRO configurations that may appear correct
but are incorrect. These cabling errors can lead to data loss if OSCRO is
implemented and a controller fails. The examples that follow involve crossconnected, unilateral, and mismatched cabling. These configuration errors must
be avoided.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
5-2
Configuration Errors to Avoid
It is important to understand that the Online Storage Controller Recovery
Utility detects cabling errors when the Verify function is used to test all OSCRO
controller pairs. If you are having a problem, run the Verify function.
Cross Connection
In the example shown in Figure 5-1, the cables are cross connected, that is, the
external connector from the active SMART-2 controller is attached to the same
ProLiant Storage System/F or /U as the internal connector of the standby
SMART-2 controller. The Online Storage Controller Recovery Utility may not
detect this error, and it may not manifest any problems until the switch occurs
from the active controller to the standby controller. When the active controller
fails with the cables this way, the system will not be able to locate the disks
because their logical SCSI port numbers will change.

This configuration error demonstrates the need to pay close attention to the
labeling and cabling of OSCRO controller pairs. Although this error would be
detected by performing a Verify function, cabling errors such as this are most
likely to occur when the cables are not labeled properly. To avoid such errors,
see the “Labeling the Cables” section in Chapter 3.

Configuration Errors to Avoid
Unilateral Connection
In the example shown in Figure 5-2, both the internal and external cables from
the active controller are connected to the same ProLiant Storage System/F
or /U. Likewise, the internal and external cables from the standby controller are
connected to the second ProLiant Storage System/F or /U. This is also an error
that the Verify function of the Online Storage Controller Recovery Utility flags.
In addition, if there are drives in both ProLiant Storage Systems, both of the
SMART-2 controllers will be attached to active SCSI buses, and the Online
Storage Controller Recovery Utility will not allow the controllers to be merged.
In the unlikely event that no drives were installed in the second ProLiant
Storage System/F or /U, however, the Online Storage Controller Recovery
Utility does not detect this error unless the Verify function is used.

This configuration error also highlights the need to label the interfaces attached
to the internal connectors of the SMART-2 controllers (as discussed in the
“Labeling the Cables” section in Chapter 3). The labels allow you to determine
which interface is connected to the active controller and which is connected to
the standby controller, without opening the system.

Configuration Errors to Avoid
Mismatched Controller Pairs
OSCRO allows you to form multiple controller pairs in a single server. Each
controller pair must conform to the configuration guidelines for single-channel
or dual-channel controller pairs. Incorrect configurations can result from
connecting the cables incorrectly, as shown in Figure 5-3. Connecting the
secondary (idle) interface of the wrong ProLiant Storage System/F or /U, for
example, causes an incorrect configuration that the Online Storage Controller
Recovery Utility can detect only if you run a Verify. If you do not run a Verify,
you will be able to merge the controllers into a controller pair but the
configuration will not function if either of the active controllers fails.

Clearing a Cable Check Error
When using PCI Hot Plug technology, a Cable Check error can be cleared by
using the PCI Hot Plug Utility to cycle power to the PCI slot housing the failed
controller. Without PCI Hot Plug technology, the server must be rebooted to
clear a Cable Check.
Verify Does Not Switch Back
If you are running a Verify operation that does not perform both switch
operations and return the controller you have designated as the active controller
to that state, the most probable cause is that you are trying to install OSCRO
with a Recovery Server Switch that has not been upgraded. If you previously
implemented either Standby Recovery Server or On-Line Recovery Server,
check to see if the original Recovery Server Switch you installed is still in
place. If so, replace it with the Recovery Server Switch that came in the
Recovery Server Option /U kit.
Wrong Device Driver
If you get the message
unknown error 0xed0e0000
you are running with old device drivers. Use the Compaq SSD for
Windows NT that is included in the Recovery Server Option /U kit, to update
the controller device drivers.
Controller Not Seen on the Online
Storage Controller Recovery Utility
If the controller you are looking for does not appear on the Online Storage
Controller Recovery Utility main screen, it is probably not a controller
supported by OSCRO. Only the following SMART-2 Array Controllers can be
made into OSCRO redundant pairs: SMART-2SL, SMART-2/P, SMART-2/E,
and SMART-2DH.

Recovering from Mass Storage
Controller Failure
OSCRO enables the server to continue operating even when a mass storage
controller fails. This section outlines the steps to replace a failed controller and
recover the fault-tolerant state of the I/O subsystem.
Recovering from mass storage controller failure differs depending on whether
the server utilizes PCI Hot Plug technology. If the controller that failed is your
boot device controller, you may need to take some action. You must make sure
the boot device controller is connected to the primary port of the ProLiant
Storage System/F or /U, that is, the one that is active after the power is cycled
on the ProLiant Storage System/F or /U.
When the power is cycled on the ProLiant Storage System/F or /U, the
Recovery Server Switch inside is reset and the primary port becomes the active
port by default. By aligning the primary port of the ProLiant Storage System/F
or /U with the active controller of the controller pair, the system recovers from
a power failure using the power-up defaults.
Recovering from Mass Storage
Controller Failure Using PCI Hot Plug
Technology
PCI Hot Plug technology and OSCRO work together to provide a means for
replacing a failed mass storage controller without shutting down the system.
The steps involved are:
1. Using the PCI Hot Plug Utility, power off the PCI slot containing the
controller.
2. Replace the controller.
3. Use the PCI Hot Plug Utility to power on the PCI slot containing the
replacement controller.

Recovering from Mass Storage
Controller Failure Without PCI Hot
Plug Technology
The steps for recovering from mass storage controller failure when you do not
have PCI Hot Plug Technology are:
1. Schedule a time when the server can be shut down.
2. Shut down the server at the scheduled time, and turn off the power.
3. Turn off the power to the ProLiant Storage System(s)/F or /U. This
resets the Recovery Server Switch.
4. Replace the failed controller.
5. Turn on the power to the ProLiant Storage System(s)/F or /U.
6. Reboot the server.
By following this procedure, the mass storage controller is replaced when
convenient for the System Administrator, restoring the I/O subsystem to a faulttolerant state.
Boot Device Considerations
A problem arises as a result of recovering from primary mass storage controller
failure without PCI Hot Plug technology in a specific case. The conditions that
present this case are:
1. The boot device controller is a member of a controller pair.
2. The boot device controller fails.
3. The backup controller takes over.
4. The server is shut down while the backup controller is acting on behalf
of the boot device controller.
5. The boot device controller is NOT repaired while the server is shut down.

6-4
Recoving from Mass Storage Controller Failure
We strongly suggest you repair the boot device controller while the server is
shut down. If for some reason you cannot repair the boot device controller
while the server is shut down, the server will not be able to find the boot device;
the standby controller is not capable of acting as the boot device controller. To
recover from this situation, perform the following steps, assuming the failed
primary controller is Controller A and the standby controller is Controller B:
1. Turn off the power to the server.
2. Disconnect both cables from SMART-2 Array Controller B.
3. Move SMART-2 controller B into the slot previously occupied by the
primary controller (A). This step promotes the other SMART-2
controller (B) so it can act as the boot device controller. It does this by
positioning it in the slot designated as First in Controller Order.
4. Connect the external and internal cables for the primary controller (A) to
Controller B.
5. Cycle the power on the ProLiant Storage Systems to ensure that the
Recovery Server Switches inside are reset.
6. When the failed mass storage controller (A) is replaced, introduce it into
the configuration as the new backup controller.
7. Run the System Configuration Utility (version 2.34A or later) to specify
the new PCI/EISA bus configuration.
Performing these steps promotes the standby controller to the new boot device
controller and ensures its connection to the primary port of the ProLiant Storage
System/F or /U. These steps are necessary to allow the system to recover
cleanly from complete power failure.

Chapter 7
Dissolving a Controller Pair
OSCRO uses updated versions of the SMART-2 device drivers to establish and
maintain controller pair(s). Windows NT upgrades include default versions of
the device drivers built to be compatible with the versions of Windows NT
being installed. The device drivers included with the operating system,
however, may not be the same as those installed under previous versions of
Windows NT. For that reason, all controller pairs should be dissolved before
installing a Windows NT upgrade. These pairs can be re-merged after the
upgrade.
You will also want to dissolve OSCRO controller pairs before doing any device
driver or controller upgrades.
NOTE: Upgrading controllers only requires dissolving and re-merging OSCRO
controller pairs when it involves upgrading the device drivers or switching from
single channel to dual channel. Upgrading from SMART-2/P to SMART-2DH, for
example, has no direct impact on an OSCRO controller pair. Moving controllers to
different PCI or EISA slots, on the other hand, does require dissolving and remerging a controller pair.
CAUTION: When dissolving a controller pair, do not reconfigure the cables
until the pair is dissolved.
Dissolving a controller pair using the Online Storage Controller Recovery
Utility is easy. To dissolve a controller pair:
1. Make sure that the controller pair does not contain any failed controllers.
Controller pairs that include a failed controller cannot be dissolved until
the failed controller is repaired.
2. Access the Online Storage Controller Recovery Utility from the Compaq
Online Storage Recovery applet on the Control Panel, or from the Compaq
System Tools folder.
3. Highlight the controller pair you want to dissolve (the highlighted line
must have a white icon). This activates the Dissolve button.

CAUTION: Because one of the two array controllers is still electrically
disconnected from the ProLiant Storage System, it should be inactive (gray)
after dissolving the controller pair. You should not reconfigure the cabling

Electrostatic Discharge
A discharge of static electricity from a finger or other conductor may damage
printed circuit boards or other static-sensitive devices. This type of damage may
reduce the life expectancy of the device.
Preventing Electrostatic Damage
To prevent electrostatic damage, observe the following procedures:
■ Avoid hand contact by transporting and storing parts in static-safe
containers.
■ Keep electrostatic-sensitive parts in their containers until they arrive at
static-free workstations.
■ Place parts on a grounded surface before removing them from their
container,
■ Avoid touching pins, leads, or circuitry.
■ Always be properly grounded when touching a static-sensitive
component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more of the following
measures when handling or installing electrostatic-sensitive parts:
■ Use a wrist strap connected by a ground cord to a grounded workstation
or the computer chassis. Wrist straps are flexible straps with a minimum
of 1 megohm +/- 10 percent resistance in the ground cords.
■ Use heel straps, toe straps, or bootstraps at standing workstations. Wear
the straps on both feet when standing on conductive floors or dissipating
floor mats.
■ Use conductive field service tools.
■ Use a portable field service kit with a folding static-dissipating work
mat.
