6. Check the cover for sharp edges, damage, or alterations that expose the internal

parts of the device.

7. Correct any problems that you find.

Internal machine checks

Ensure that you perform an internal machine check before you install the SAN Volume Controller.

Perform the following steps to conduct the internal machine check:

1. Check for any non-IBM changes that might have been made to the machine. If any are present, obtain the “Non-IBM Alteration Attachment Survey,” form number R009, from the IBM branch office. Complete the form and return it to the branch office.

xviii IBM System Storage SAN Volume Controller: Hardware Installation Guide

2. Check the condition of the inside of the machine for any metal or other contaminants, or any indications of water, other fluid, fire, or smoke damage.

3. Check for any obvious mechanical problems, such as loose components.

4. Check any exposed cables and connectors for wear, cracks, or pinching.

Checking the grounding of a SAN Volume Controller, the UPS, and the redundant ac power switch

Ensure that you understand how to check the grounding of a SAN Volume Controller, the uninterruptible power supply (UPS), and the optional redundant ac power feature.

All SAN Volume Controller models support the use of the 2145 uninterruptible power supply-1U (2145 UPS-1U) and the optional redundant ac power switch. The SAN Volume Controller 2145-4F2 also supports the use of the 2145 UPS.

Perform the following steps to test the grounding of a SAN Volume Controller. Follow the steps for the SAN Volume Controller configuration you are using. Before you start, confirm you know the SAN Volume Controller model type, the UPS type, and whether you are using redundant ac power. Note the location of the signal cables that are attached to the SAN Volume Controller.

When you are asked to test the grounding continuity, use your local procedures to perform the test. The test is successful if the measured resistance is 0.1 ohm or less.

Attention: Some electrical circuits can be damaged if the external signal cables are present at the SAN Volume Controller while it is undergoing a grounding test.

1. Ensure that the SAN Volume Controller node is powered off. See “MAP 5350: Powering off a SAN Volume Controller node” in the IBM System Storage SAN Volume Controller: Service Guide.

2. If the UPS is a 2145 UPS, ensure that other SAN Volume Controller nodes that are powered from the UPS are powered off.

3. Use the power button to power off the UPS.

4. Disconnect all signal cables from the SAN Volume Controller node, which

includes the following cables:

v The fibre channel cables v The Ethernet cable v The serial cable that is connected to the UPS.

5. Disconnect all signal cables from the UPS. If the UPS is a 2145 UPS, there

might be multiple signal cables.

6. If the UPS is a 2145 UPS, disconnect any power cables that are connected to SAN Volume Controller nodes, except the one that is being tested.

7. If redundant ac power is not used, disconnect the UPS power cable from the site power distribution unit.

8. If redundant ac power is used, power off any SAN Volume Controller that is being supplied from the redundant ac power switch, and remove the power cable to this system from the redundant ac power switch.

9. If redundant ac power is used, disconnect both input power leads from the site power distribution units.

10. If redundant ac power is not used, test the grounding continuity between a conductive area on the SAN Volume Controller frame and the ground pin on the plug of the UPS input power cable.

About this guide xix

11. If redundant ac power is used, test the grounding continuity between a

conductive area on the SAN Volume Controller frame and the ground pin on the plug of the main power cable of the redundant ac power switch. If the test is successful, test the grounding continuity between a conductive area on the SAN Volume Controller frame and the ground pin on the plug of the backup power cable of the redundant ac power switch. Both tests must be successful.

12. After you have completed testing the grounding continuity, perform one of the following procedures, depending on the outcome of the test.

v If the test is successful, reconnect any cables that were removed, and power

on any UPSs and SAN Volume Controller nodes that were powered off.

v If the test was not successful, ensure that all cables are securely connected.

If the test still fails, test the individual system components. Before you test the individual components, remove all cables from the components. If any component test fails, replace the component. After each component has been tested and the failing ones have been replaced, repeat the complete system test by returning to step 1 on page xix. Test the components in the following order:

a. The SAN Volume Controller node, from the frame to the ground pin of

the input power receptacle.

b. The UPS from the ground pin of the input power receptacle to the

ground conductor of the output power receptacle.

c. If used, the redundant ac power switch from the ground pin of the main

input power receptacle to the ground conductor of the output power receptacle, and from the ground pin of the backup input power receptacle to the ground conductor of the output power receptacle.

d. The SAN Volume Controller node to UPS power cable assembly,

between the two ground conductors of the power cable.

e. The UPS input power cable, between the two ground conductors of the

power cable.

f. If used, the redundant ac power switch main input power cable, between

the two ground conductors of the cable.

g. If used, the redundant ac power switch backup input power cable,

between the two ground conductors of the cable.

Inspecting the UPS for unsafe conditions

Ensure that you take the time to inspect the uninterruptible power supply (UPS) for unsafe conditions.

Consider the following conditions and their potential safety hazards:

Electrical hazards (especially primary power)

Primary voltage on the frame can cause serious or lethal electrical shock.

Explosive hazards

A bulging capacitor can cause serious injury.

Mechanical hazards

Loose or missing items (for example, nuts and screws) can cause serious injury.

caution when working in a potential safety hazard that is not covered in the

Use safety checks. If unsafe conditions are present, determine how serious the hazards are and whether you can continue before you correct the problem.

xx IBM System Storage SAN Volume Controller: Hardware Installation Guide

Using the following inspection checklist as a guide, inspect the UPS for unsafe conditions. If necessary, see any suitable safety publications.

1. If any equipment has been damaged during the shipment, keep the shipping cartons and packing materials.

2. Perform the following steps to file a claim for the shipping damage: a. File with the carrier within fifteen days of receipt of the equipment. b. Send a copy of the damage claim within fifteen days to your service

support representative.

Emergency power-off shutdown

The SAN Volume Controller and each uninterruptible power supply (UPS) support emergency power-off (EPO) shutdowns.

In the event of a room EPO shutdown, the 2145 uninterruptible power supply (2145 UPS) detects a loss of input power. This power loss is reported to the SAN Volume Controller 2145-4F2, which completes the process of shutting down the UPS within five minutes.

Attention: The 2145 UPS power off shutdown is normally controlled by the SAN Volume Controller 2145-4F2. If an EPO event occurs, but no SAN Volume Controller 2145-4F2 nodes that are connected to a 2145 UPS have been powered on since the 2145 UPS was powered on, you must remove output power from the UPS. To do this, press and hold the off button on the front panel of the 2145 UPS for at least four seconds.

Checking the safety labels on the SAN Volume Controller

Before you install, use, or service the SAN Volume Controller, you must ensure that you understand the safety labels.

Handling static-sensitive devices

Ensure that you understand how to handle devices that are sensitive to static electricity.

Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static protective bags until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its anti-static bag, touch it to an unpainted metal part

of the system unit for at least 2 seconds. (This action removes static electricity from the package and from your body.)

v Remove the device from its package and install it directly into your SAN

Volume Controller, without putting it down. If it is necessary to put the device down, place it onto its static-protective bag. (If your device is an adapter, place it component side up.) Do not place the device onto the cover of the SAN Volume Controller or onto a metal table.

v Take additional care when you handle devices during cold weather because

heating reduces indoor humidity and increases static electricity.

2 IBM System Storage SAN Volume Controller: Hardware Installation Guide

Chapter 2. SAN Volume Controller overview

The SAN Volume Controller combines hardware and software into a comprehensive, modular appliance that uses symmetric virtualization.

Symmetric virtualization is achieved by creating a pool of managed disks (MDisks) from the attached storage subsystems. Those storage systems are then mapped to a set of virtual disks (VDisks) for use by attached host systems. System administrators can view and access a common pool of storage on the SAN. This lets the administrators use storage resources more efficiently and provides a common base for advanced functions.

A SAN is a high-speed fibre-channel network that connects host systems and storage devices. It allows a host system to be connected to a storage device across the network. The connections are made through units such as routers, gateways, hubs, and switches. The area of the network that contains these units is known as the fabric of the network.

The SAN Volume Controller is analogous to a logical volume manager on a SAN. The SAN Volume Controller performs the following functions for the SAN storage that it controls:

v Creates a single pool of storage v Provides logical unit virtualization v Manages logical volumes v Provides the following advanced functions for the SAN:

– Large scalable cache – Copy Services

- FlashCopy® (point-in-time copy)

- Metro Mirror (synchronous copy)

- Global Mirror (asynchronous copy)

- Data migration

Space management

–

- Mapping that is based on desired performance characteristics

- Metering of service quality

SAN Volume Controller node is a rack-mounted unit that you can install in a

Each standard Electrical Industries Alliance (EIA) 19-inch rack. The nodes are always installed in pairs, with one-to-four pairs of nodes constituting a cluster. Each pair of nodes is known as an I/O group.

All I/O operations that are managed by the nodes in an I/O group are cached on both nodes. Each virtual volume is defined to an I/O group. I/O groups take the storage that is presented to the SAN by the storage subsystems as MDisks and translates the storage into logical disks, known as VDisks, that are used by applications on the hosts. Each node must reside in only one I/O group and provide access to the VDisks in that I/O group.

There are four models of SAN Volume Controller nodes: v SAN Volume Controller 2145-8G4

v SAN Volume Controller 2145-8F4 v SAN Volume Controller 2145-8F2 v SAN Volume Controller 2145-4F2

SAN fabric overview

The SAN fabric is an area of the network that contains routers, gateways, hubs, and switches. A single cluster SAN contains two distinct types of zones: a host zone and a disk zone.

In the host zone, the host systems can identify and address the SAN Volume Controller nodes. Yo u can have more than one host zone. Generally, you create one host zone for each host type. In the disk zone, the SAN Volume Controller nodes identify the disk drives. Host systems cannot operate on the disk drives directly; all data transfer occurs through the SAN Volume Controller nodes. Figure 1 shows several host systems that are connected in a SAN fabric.

Figure 1. Example of a SAN Volume Controller cluster in a fabric

A cluster of SAN Volume Controller nodes is connected to the same fabric and presents virtual disks (VDisks) to the host systems. Yo u create these VDisks from units of space within a managed disk (MDisk) group. An MDisk group is a collection of MDisks that are presented by the storage subsystems (RAID controllers). The MDisk group provides a storage pool. Yo u specify how each group is created, and you can combine MDisks from different manufacturers’ controllers in the same MDisk group.

Note: Some operating systems cannot tolerate other operating systems in the same

fabric. For example, you can have a SAN that contains one host that runs on an AIX® operating system and another host that runs on a Windows operating system.

Yo u can remove one SAN Volume Controller node in each I/O group from a cluster when hardware service or maintenance is required. After you remove the SAN Volume Controller node, you can replace the field replaceable units (FRUs) in the SAN Volume Controller node. All communication between disk drives and all communication between SAN Volume Controller nodes is performed through the SAN. All SAN Volume Controller node configuration and service commands are sent to the cluster through an Ethernet network.

Each SAN Volume Controller node contains its own vital product data (VPD). Each cluster contains VPD that is common to all the SAN Volume Controller nodes in the cluster, and any system that is connected to the Ethernet network can access this VPD.

Cluster configuration information is stored on every SAN Volume Controller node that is in the cluster to allow concurrent replacement of FRUs. When a new FRU is installed and when the SAN Volume Controller node is added back into the cluster, configuration information that is required by that SAN Volume Controller node is read from other SAN Volume Controller nodes in the cluster.

SAN Volume Controller operating environment

Yo u must set up your SAN Volume Controller operating environment using the supported multipathing software and hosts.

Minimum requirements

Yo u must set up your SAN Volume Controller operating environment according to the following requirements:

v Minimum of one pair of SAN Volume Controller nodes v Minimum of two uninterruptible power supplies v One master console per SAN installation for configuration

Fibre-channel port numbers and worldwide port names

Fibre-channel ports are identified by their physical port number and by a worldwide port name (WWPN).

The physical port numbers identify fibre-channel cards and cable connections when you perform service tasks. The WWPNs are used for tasks such as fibre-channel switch configuration and to uniquely identify the devices on the SAN.

The physical port numbers are 1 - 4, counting from left to right when you view the rear panel of the SAN Volume Controller. The WWPNs are derived from the worldwide node name (WWNN) of the SAN Volume Controller in which the card is installed.

The WWNN is in the form 50050768010XXXXX, where XXXXX is initially derived from the unit and is specific to a SAN Volume Controller. You can change the XXXXX value by using the front panel to facilitate service controller concurrent replacement and to enable some concurrent upgrade operations.

The WWPNs are in the form 5005076801QXXXXX, where XXXXX is as previously stated and Q is related to the port number as follows:

Chapter 3. Redundant ac power switch

The redundant ac power switch is an optional feature that makes the SAN Volume Controller nodes more resilient to power failure. The redundant ac power switch is not a replacement for an uninterruptible power supply (UPS), you must still use a 2145 UPS-1U for each node.

Yo u must connect the redundant ac power switch to two-independent power circuits. One power circuit connects to the main power input port and the other power circuit connects to the backup power input port. If the main power to the SAN Volume Controller node fails for any reason, the redundant ac power switch automatically uses the backup power source. When power is restored, the redundant ac power switch automatically changes back to using the main power source.

Place the redundant ac power switch in the same rack as the SAN Volume Controller node. The redundant ac power switch logically sits between the rack power distribution unit and the 2145 UPS-1U.

Yo u can use a single redundant ac power switch to power one or two SAN Volume Controller nodes. If you use the redundant ac power switch to power two nodes, the nodes must be in different I/O groups. In the event that the redundant ac power switch fails or requires maintenance, both nodes power off. Because the nodes are in two different I/O groups, the hosts do not lose access to the backend disk data.

For maximum resilience to failure, use one redundant ac power switch to power each SAN Volume Controller node.

The following graphic shows a redundant ac power switch.

svc00297

Preparing your redundant ac power environment

Ensure that your physical site meets the installation requirements for the redundant ac power switch.

The redundant ac power switch requires two independent power sources that are provided through two rack-mounted power distribution units (PDUs). The PDUs

must have IEC320-C13 outlets.

The redundant ac power switch comes with two IEC 320-C19 to C14 power cables to connect to rack PDUs. There are no country-specific cables for the redundant ac power switch.

The power cable between the redundant ac power switch and the 2145 uninterruptible power supply-1U (2145 UPS-1U) is rated at 10 A.

Chapter 4. Using the 2145 UPS-1U

The 2145 uninterruptible power supply-1U (2145 UPS-1U) provides a SAN Volume Controller node with a secondary power source if you lose power from your primary power source due to power failures, power sags, power surges, or line noise.

Unlike the traditional UPS that enables continued operation of the devices that they supply when power is lost, these UPS units are used exclusively to maintain data that is held in the SAN Volume Controller dynamic random access memory (DRAM) in the event of an unexpected loss of external power. Data is saved to the internal disk of the SAN Volume Controller node. The UPS units are required to power the SAN Volume Controller nodes even if the input power source is

considered uninterruptible.

The SAN Volume Controller 2145-8G4, SAN Volume Controller 2145-8F4, and SAN Volume Controller 2145-8F2 nodes can operate only with the 2145 UPS-1U. The SAN Volume Controller 2145-4F2 node can operate with either the 2145 UPS or the 2145 UPS-1U.

Note: The UPS maintains continuous SAN Volume Controller-specific

communications with its attached SAN Volume Controller nodes. A SAN Volume Controller node cannot operate without the UPS. The UPS must be used in accordance with documented guidelines and procedures and must not power any equipment other than SAN Volume Controller nodes.

2145 UPS-1U configuration

A 2145 UPS-1U powers one SAN Volume Controller node. All SAN Volume Controller model types are supported by the 2145 UPS-1U.

To make the SAN Volume Controller cluster more resilient to power failure, the 2145 UPS-1Us can be connected to the redundant ac power switch. If a redundant ac power switch is not used, connecting the two UPSs that are powering an I/O group to different, independent electrical power sources allows the SAN Volume Controller cluster to continue to operate with reduced capacity if a single power source fails.

Each UPS must be in the same rack as the node it powers.

Attention: Do not connect the UPSs to an input power source that does not conform to standards.

Each UPS includes power (line) cords that connect the UPS to either a redundant ac power switch, if one exists, a rack power distribution unit (PDU), if one exists, or to an external power source.

| | | | |

Each UPS is connected to a SAN Volume Controller node with a power cable and a signal cable. To avoid the possibility of power and signal cables being connected to different UPS units, these cables are wrapped together and supplied as a single field replaceable unit. The signal cable enables the SAN Volume Controller node to read status and identification information from the UPS.

2145 UPS-1U operation

Each SAN Volume Controller node monitors the operational state of the uninterruptible power supply (UPS) to which it is attached.

If the UPS reports a loss of input power, the SAN Volume Controller node stops all I/O operations and dumps the contents of its dynamic random access memory (DRAM) to the internal disk drive. When input power to the UPS is restored, the SAN Volume Controller node restarts and restores the original contents of the DRAM from the data saved on the disk drive.

A SAN Volume Controller node is not fully operational until the UPS battery charge state indicates that it has sufficient capacity to power the SAN Volume Controller node long enough to save all of its memory to the disk drive. In the

event of a power loss, the UPS has sufficient power for the SAN Volume Controller to save all its memory to disk at least twice. For a fully-charged UPS, even after battery capacity has been used to power the SAN Volume Controller node while it saves DRAM data, sufficient battery capacity remains to allow the SAN Volume Controller node to become fully operational as soon as input power is restored.

Important: Do not shut down a UPS without first shutting down the SAN Volume

Controller node that it supports. Data integrity can be compromised by pushing the 2145 UPS-1U on/off button when the node is still operating. However, in the case of an emergency, you can manually shut down the UPS by pushing the 2145 UPS-1U on/off button when the node is still operating. Service actions must then be performed before the node can resume normal operations. If multiple UPSs are shut down before the nodes they support, data can be corrupted.

Controls and indicators for the 2145 UPS-1U

All controls for the 2145 uninterruptible power supply-1U (2145 UPS-1U) are located on the front panel assembly.

1. Prepare for the SAN Volume Controller hardware installation by confirming that you have all the planning information and parts that you require.

2. Install and verify the redundant ac power switch, if it is to be used and is not already being used for a node.

3. Install the UPS.

4. Install the node.

5. Connect the fibre-channel and Ethernet cables to the node.

6. Connect the node to the UPS.

7. Verify the node.

8. Install and verify the master console. Optionally, you can perform this step

first.

After you finish these steps, the hardware installation is complete.

Preparing for the SAN Volume Controller hardware installation

Yo u must perform the steps to prepare for the installation of the optional redundant ac power switch, the uninterruptible power supply (UPS), the master console, and the SAN Volume Controller.

Perform the following steps to prepare for installation:

| | | | | | | | | |

1. Ensure that you have everything you need for installation, including the customer-completed planning tables and charts that are provided at http://www.ibm.com/storage/support/2145. The IBM System Storage SAN Volume Controller: Planning Guide provides guidelines for completing the planning tables and charts. These tables include the location of hardware, cable connection, and configuration data information that you need to complete the installation procedures. If you are connecting cables to switches that are currently in use, confirm with the customer that it is safe for you to proceed. Go no further with these instructions until you are satisfied that all the information is correct and valid.

2. Check all the parts and quantities against the parts that are shown in Figure 10 on page 36 to make sure that everything has been delivered. If any piece is missing, contact the appropriate IBM representative.

svc00293

Testing the redundant ac power switch

Yo u can test the redundant ac power switch before you continue installing other SAN Volume Controller components. You can test the redundant ac power switch later if a suitable test device is not available.

Yo u can test whether the redundant ac power switch correctly switches between power inputs when the main input power fails or is restored. Yo u can either use a volt meter to measure for voltage at the output or attach a work light, or similar device with a C14 plug, to the redundant ac power switch output and verify that it remains powered when a failure is simulated on either of the inputs.

Note: If you do not have a separate device to verify that there is power on the

output port of the redundant ac power switch, you can delay this test until you connect the redundant ac power switch to the uninterruptible power supply (UPS). In that case, power on the UPS (not the SAN Volume Controller node) and see if it changes to battery power. The test fails if the UPS switches to battery power for more than five seconds (any transient indications of battery power can be ignored).

When the instructions say “remove power”, you can either switch the power off if the site power distribution unit has outputs that are individually switched or remove the specified redundant ac power switch power cable from the outlet of the site power distribution unit.

Note: If at any time there is no power on the output socket, ensure that the power

distribution sockets of the power source are powered. If they are, recheck all of the connections and decide if the redundant ac power switch assembly, which includes the input power cables, is defective.

Verify that the node is booting without error. If it boots without error, either the Charging message or Cluster: is displayed in the first line of the front-panel display.

Chapter 6. Installing the SAN Volume Controller 2145-8G4 hardware 59

In most cases, the battery is delivered charged, so you do not see the Charging message. If the Charging message is displayed, you will also see a progress bar on the second line. Battery charging can take up to three hours to complete. In the meantime, if you press any navigation buttons, the battery charging menu is replaced, but battery charging continues. (You can re-enter the menu system to view the charging progress, as described in step 4.) When the battery is charged enough, Cluster: is displayed on the first line of the front-panel display. The second line is left blank.

2. Press and hold the select button for five seconds. The check light comes on and a display test is performed. When the display test is complete, the check light goes off and a button test is started.

3. Press the up, down, left, and right buttons to verify that they are working. Figure 36 shows four examples of what the front panel should display when you press the buttons. When you have finished testing the buttons, press and hold the select button for five seconds in order to exit the test.

8. Press and release the up or down button until the FC Port-1 option shows in the display.

9. Check whether the second line of the front-panel display shows the message Active. If Active is not shown on the second line, go to “MAP 5600: Fibre channel” in the IBM System Storage SAN Volume Controller: Service Guide to repair the fault.

10. Press and hold the down button.

11. Press and release the select button.

12. Release the down button. The operational speed of the fibre-channel link is

displayed. Use the cable connection table that is provided by the customer to verify that the fibre-channel link is operating at the expected speed. If the operational speed does not match the expected speed, go to “MAP 5600: Fibre channel” in the IBM System Storage SAN Volume Controller: Service Guide to repair the fault.

13. Press the select button to return to the fibre-channel status display.

14. Press the right button to display each port in turn and repeat the above speed

check.

15. If you want to select a language other than English, perform the following steps:

a. Press the up or down button until Select Language? is displayed. b. Press the select button. c. Press the left or right button until the required language is displayed. d. Press the select button.

When the battery is fully charged–if it needed to be charged–the Charging message is replaced by Cluster: and the progress bar no longer displays. The installation of the SAN Volume Controller hardware is now complete. No software installation is required. Continue with the instructions in the IBM System Storage SAN Volume Controller: Software Installation and Configuration Guide to, if necessary, create a new SAN Volume Controller cluster and to add the nodes into a SAN Volume Controller cluster.

Installing the hardware master console

If the master console hardware product option is included with the SAN Volume Controller, you must install it and perform initial hardware configuration for it.

Before you begin the installation, ensure that you have completed the following tasks:

v Important: Review and complete all of the safety checks that are detailed in the

documentation for the master console IBM eServer xSeries hardware, the keyboard, and the display.

| |

v Ensure that you have all the customer-completed information that you need,

including the configuration data table, hardware location chart, and the cable

you experience a problem with your master console, use the 2145 machine type

If and the serial number of the SAN Volume Controller node that was installed with the master console to open a hardware problem.

Perform the following steps to install the master console hardware option:

| | | |

Note: Do not install the pull-out monitor and keyboard of the master console

directly below a SAN Volume Controller node. The front panel of the node protrudes beyond the front of the rack and overlaps part of the monitor, which prevents you from being able to open it.

1. Install the master console hardware in the rack, following the hardware installation instructions that are provided by your xSeries Installation Guide and by the instructions that are provided with the mounting rails.

| | | | | | |

If there are any devices directly above and below the master console server unit, it might be very difficult to reach in and connect the cables to the back of the server after it is placed in the rack. If that is the only slot available, connect the keyboard, mouse, monitor, and Ethernet cables at the back of the master console server before installing it in the rack. Leave the other end of the Ethernet cable disconnected from the network until you are directed to connect it.

Important:

Do not follow any software installation procedures in the xSeries

Installation Guide.

2. Ensure that no cables are connected to the Ethernet ports.

3. Turn on the master console. a. Type administrator in the User ID field. b. Type passw0rd in the password field; this password applies to all required

password fields. The master console continues to start.

Note: This process can take several minutes before all services are started

and operations are completely responsive.

c. Click OK if you receive any messages that a network interface card port is

offline.

4. Check that the reference identification tag is securely fastened to the front panel of the master console. The tag indicates the machine type 2145 and the serial number of the SAN Volume Controller node that is being installed with the master console.

5. IMPORTANT: This step must be the last step that you perform on the master console before you hand over the machine to the user. It sets up the master console so that it presents a Windows license agreement screen at the next power on and then shuts down the master console.

a. Select Start → Run b. Type c:\sysprep\sysprep.exe c. Click OK. The System Preparation Tool panel is displayed. d. Select Don’t re-generate security ID. e. Select Reboot from the Shutdown Mode list. f. Click Reseal.
