• Operating system support. MPE/iX Operating System, Release 7.0
Express 1 with patch MPEMX36, or Release 7.5
Before installing the disk array, ensure the environment conforms to these
requirements:
• Fibre Channel host adapters (for A-Class and N-Class only) or HVD SCSI
adapters (for Series 9x8, Series 9x9, and Series 99x system models). Refer
to the adapter documentation for installation. Use of SCSI adapters also
requires SCSI-FC Fabric Routers as described later in this document.
• (Recommended) HP StorageWorks Command View XP with LUN
management feature or Remote Control with the LUN Configuration
Manager XP option. These are used to configure disk array ports and paths.
• (Recommended) HP StorageWorks Secure Manager XP. Allows the host to
access only authorized array devices.

HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Fibre Channel interface
The MPE/iX host can use the A7895A 2 Gbps Fibre Channel HBA to
connect to the disk array. The disk array port should not use auto negotiate
to detect the speed of the host Fibre Channel adapter. Configure it "hard" to
either 1 or 2 Gbps.
Even though the interface is Fibre Channel, this guide uses the term “SCSI
disk” because disk array devices are defined to the host as SCSI disks.
SCSI-FC Fabric Router
The HP e3000 supports the A5814A-003 SCSI-FC Fabric Router hardware,
which enables an HP e3000 with HVD SCSI HBAs to connect to a disk
array with a Fibre Channel interface. The router converts data between the
SCSI I/O interface at the host server and the Fibre Channel I/O interface at
the disk array.
Device types
The HP e3000 system supports only OPEN-x device types. LUSE and CVS
device types are not supported.
Failover
The HP e3000 system supports I/O path failover for the disk arrays by
means of the MPE/iX High Availability FailOver/iX software product.
SNMP configuration
The XP family of disk arrays supports standard Simple Network
Management Protocol (SNMP) to remotely manage the disk array from the
host. The SNMP agent on the remote console PC or Command View can
provide status and Remote Service Information Message (R-SIM) reporting
to the SNMP manager on the host for up to eight disk arrays.
Installation
15
Command View does not execute on the HP e3000 and must be executed
on another supported platform (such as Windows or HP-UX).
Refer to the operating system documentation to configure the SNMP
manager on the host.
RAID Manager command devices
RAID Manager manages Business Copy (BC) or Continuous Access
(CA) operations from a host server. To use RAID Manager with BC or
CA, use Command View or LUN Configuration Manager to
designate at least one disk array LDEV as a command device. Refer
to the Command View or LUN Configuration Manager user guide
for information about how to designate a command device.
Caution
16
An LDEV designated as a command device cannot contain any MPE/iX
files or data. Create a single member volume set through the VOLUTIL
utility program. Then VSCLOSE it, SCRATCHVOL it, and convert it to a
command device.
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX

Installation
17
Install and configure the disk array
The HP service representative performs these tasks:
• Assembling hardware and installing software
• Loading the microcode updates
• Installing the channel adapters (CHAs) and cabling
• Installing and formatting devices
After these tasks are finished, you will use Command View or LUN
Configuration Manager to complete the tasks listed below. If you do not
have Command View or LUN Configuration Manager, your HP service
representative can perform these tasks for you.
Setting the Host Mode for the disk array ports
The disk array ports have Host Modes that you must set depending on the
host you use. After the disk array is installed, use Command View (shown)
or LUN Configuration Manager to set the Host Mode for each port.
The host mode setting for MPE/ix is 08.
18
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Setting the System Option Modes
The HP service representative sets the System Option Mode(s) based on the
operating system and software configuration of the host.
Configuring the Fibre Channel ports
Configure the Fibre Channel ports on the disk array using Command View
(shown) or the Fibre Parameter window in LUN Configuration Manager.
Select the settings for each port based on your storage area network
topology. Use switch zoning if you connect different types of hosts to the
array through the same switch..
Installation
19
Fibre address
In fabric environments, the port addresses are assigned automatically. In
arbitrated loop environments, set the port addresses by selecting a unique
arbitrated loop physical address (AL-PA) or loop ID for each port.
Fabric and connection parameter settings
For HP e3000 systems, set the port topology to FABRIC ON and the
connection parameter to FC-AL. This provides an NL-port on the disk
array (public arbitrated loop) and is the recommended supported topology.
20
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Install the host hardware
This section explains how to install and configure the host and host bus
adapters (HBAs) that connect the host to the disk array.
If you plan to use Fibre Channel switches to create a SAN environment,
install them according to the manufacturer's instructions.
If you plan to connect to the disk arrays using HP e3000 SCSI HBAs (HVD
required), install the required A5814A-003 SCSI-FC Fabric Routers
according to the instructions in the SCSI-Fibre Channel Router Installation
and User Guide.
When you are configuring the fabric switch for use with routers, make sure
that you configure initiator zoning. (See Jazz article “A guide to Success
with the A5814A-003 SCSI-FC Router,” referenced on page 6.)
Installing the host system
Install the host system following the HP e3000 system installation
instructions.
Installing and configuring the HBAs
Install and configure the host bus adapter cards using the HP HBA
installation instructions, driver software, and setup utilities.
When you are installing A6795A Fibre Channel HBAs on A-Class and
N-Class systems, be sure to record the I/O slot paths where you install the
cards. You will need the I/O paths of these HBAs later during the I/O
configuration procedure. For SCSI HBA installations, recording the I/O
paths is not required. You can determine those I/O later using the
MAPPER/MAPPER2 facility.
Installation
21
Fabric zoning and LUN security
If you plan to use clustering, install and configure the clustering software
on the servers.
Clustering is the organization of multiple servers into groups. Within a
cluster, each server is a node. Multiple clusters compose a multi-cluster
environment. The following example shows a multi-cluster environment
with three clusters, each containing two nodes. The nodes share access to
the disk array.
Within the Storage Area Network (SAN), the clusters may be
homogeneous (all the same operating system) or they may be
heterogeneous (mixed operating systems). How you configure LUN
security and fabric zoning depends on the operating system mix and the
SAN configuration.
22

Connect the disk array
The HP service representative connects the disk array to the HP e3000 host
by:
1. If connecting SCSI cables, shutting down and powering off the host.
2. Verifying operational status of the disk array channel adapters, LDEVs,
and paths.
3. Connecting the I/O cables between the disk array and the host. Fibre
Channel cables run from the disk array to either the host system (direct
native Fibre Channel connection), a Fibre Channel switch (fabric Fibre
Channel connection), or to an A5814A-003 SCSI-FC Fabric Router
(host SCSI to disk array Fibre Channel connection). If you use a
SCSI-FC Router, run SCSI I/O cables from the router to the host system.
4. Powering on all peripherals if they were turned off.
5. Powering on and booting up the host if it was turned off.
6. Verifying the ready status of the disk array and peripherals.
24
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Determining the paths
Use Command View (shown) or LUN Configuration Manager to map paths
between ports and volumes within the disk array. The paths (LUNs) you
create provide the host access to array devices. For detailed instructions,
refer to the Command View or LUN Configuration Manager user guide.
Write down the LUNs for later use in configuring or verifying the host.
Storage capacity per path
An important difference between MPE/iX and other operating systems
(such as HP-UX) is the determination of disk capacity on a path. MPE/iX is
very sensitive to spindle count (LUNs) per path. If this count exceeds 16
per bus or path, performance problems may result.
Installation
25
To determine the available storage capacity in a path, subtract required
system and application I/O space from the total disk capacity and divide the
result by the spindle count (number of LUNs) in the path.
If performance information isn't available, create a configuration similar to
the installation you had before migrating to the XP array, but be sure not to
exceed 16 LUNs per path. Exceeding this number may cause MPE/iX to
issue more I/O requests than the XP array can service.
26
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Load the OS software
For an existing host requiring an OS update before installing the array,
follow the instructions in the HP e3000 MPE/iX System Software
Maintenance Manual to install or to update the OS.
The OS must be MPE/iX 7.0 or MPE/iX 7.5.
If you are installing a new MPE/iX OS onto an XP disk array that will serve
as the boot disk (MPE/iX Ldev 1), refer to Appendix C. The appendix
provides for instructions on obtaining the required primary boot path of
that disk array device. Setting the primary boot path into the processor’s
PDC memory is a required first step for OS software installation.
If, however, you are installing or updating an OS not using a newly
connected XP disk array as Ldev 1, determine the primary boot path by the
normal HP e3000 methods (for example, ODE> run MAPPER or
MAPPER2 or by using fcscan).
Installation
27
Configure the disk array devices in MPE/iX
Use either the SYSGEN utility program or the IOCONFIG utility command
to perform I/O configuration of the new XP disk array devices for the
MPE/iX OS.
The SYSGEN utility allows you to prepare a new I/O configuration for the
system, but the new configuration does not take effect until the system is
rebooted.
The IOCONFIG command prepares a new I/O configuration and puts it
into effect immediately, while the system is up, without a reboot.
Both configuration utilities execute in the normal MPE/iX system
environment while the system is up and running. Therefore you must boot
and start the OS from the MPE/iX Ldev 1 boot disk before you can perform
configuration.
For a pre-existing system to which new XP disk array devices are being
added, you will already have an operable system on an existing Ldev 1 boot
disk that you can start up. For a newly installed system, boot the system
from the primary boot path just used to install the system, and start the OS
using the appropriate factory configuration group, as described in the
System Software Maintenance Manual.
Regardless of which configuration utility you choose, you must determine
the system I/O paths of the XP disk array devices’ internal LUNs in order to
add those devices to the system I/O configuration.
The procedure to determine the I/O paths depends on the I/O interface
attachment method for your system:
• Native Fibre Channel (A-Class and N-Class systems running
MPE/iX 7.5)
OR
• SCSI-FC Fabric Router (available for all systems).
28
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Follow the procedure below that applies to your system:
• "Configuring with native Fibre Channel disk array attachment"
(page 29)
• "Configuring with SCSI-FC fabric router disk array attachment"
(page 32)
Configuring with native Fibre Channel disk array attachment
For native Fibre Channel attachment of disk arrays, MPE/iX Release 7.5
provides the new fcscan utility which is capable of determining the I/O
paths (both in SYSGEN and in PDC formats) for the disk arrays. Before
fcscan can do this, the I/O paths of the Fibre Channel HBAs must first be
configured in MPE/iX, using either SYSGEN or IOCONFIG.
This is the overall procedure for configuring disk arrays with Fibre Channel
attachment:
• Boot and start the system.
• Use SYSGEN or IOCONFIG to configure the I/O paths of the Fibre
Channel HBAs. (Your recorded these I/O paths when you installed
the HBAs into the system.)
• Use fcscan -h to determine the I/O paths for the disk arrays’ N-ports
and LUNs. Using fcscan also verifies disk array device recognition.
• Use SYSGEN or IOCONFIG to I/O configure the disk arrays’
N-ports and LUNs.
After completing the I/O configuration procedure, create MPE/iX volume
sets and disk volumes on the configured XP disk array devices.
The following sample I/O configuration procedure uses IOCONFIG to
perform immediate I/O configuration and fcscan –h to determine device
paths for native Fibre Channel attachment of XP disk arrays. In this
example there are two XP disk arrays, each routed through a SAN FC
switch, and then each attached to an A6795A Fibre Channel HBA on the
server host. The procedure begins after the system has been booted and
started, and for brevity only two LUNs within each XP disk array are
shown being configured by IOCONFIG.
Installation
29
Further detailed information about determining I/O paths for Fibre Channel
disk arrays can be found in the HP e3000 Fibre Channel Mass Storage
Adapters Service and User Manual, and in the MPE/iX Release 7.5
Communicator article “Fibre Channel Device and Adapter Support on HP
e3000 Systems.”
1. With the system booted up, use IOCONFIG to configure the I/O paths
for the Fibre Channel HBAs (located at paths 0/4/0/0 and 0/6/0/0 in this
example):

Configuring with SCSI-FC fabric router disk array attachment
Configure disk array devices attached through the SCSI-FC Fabric Router
in the same way as for other SCSI disk devices. No special MPE/iX
configuration steps are required. However, before proceeding read the
guidelines in the "Jazz Router Paper" cited on page 6.
Use the MAPPER (or MAPPER2 for A-Class and N-Class) I/O mapping
utility program in the Offline Diagnostic Environment (ODE) to display the
I/O paths for the SCSI HBAs and the disk array devices (targets and
LUNs). Then use either SYSGEN or MPE/iX’s IOCONFIG utility
command and the I/O paths reported by MAPPER to perform the MPE/iX
I/O configuration of SCSI HBAs and disk Ldevs.
To configure disk array devices attached by SCSI-FC Fabric Router:
1. Boot the system to the ISL> prompt on the primary boot path.
2. Invoke the ODE (Offline Diagnostic Environment) system from the
ISL> prompt.
3. Run the MAPPER (or MAPPER2 for A- and N-Class systems) I/O
mapping utility within ODE.
Running MAPPER will verify that the disk array devices are
recognized by the host system. MAPPER should “see” and report the
presence of all of the new SCSI HBAs and XP disk array devices.
4. Locate the I/O paths for the SCSI HBAs and disk array devices in the
MAPPER output, and record the paths for later use in SYSGEN or
IOCONFIG.
5. Exit the ODE system back to the ISL> prompt.
6. Start MPE/iX on the primary boot path.
7. Run either SYSGEN or IOCONFIG to perform I/O configuration of the
SCSI HBAs for the disk array devices and the disk array Ldevs.
8. For SYSGEN, after saving the I/O configuration, you must shut down
and restart the OS to put the new configuration into effect. For
IOCONFIG, the new configuration is immediately effective without any
shutdown and reboot.

9. Use the MPE/iX VOLUTIL utility to create volume sets and volumes
on the new disk array devices.

Troubleshooting
This section describes resolutions for various error conditions you may
encounter.
If you are unable to resolve an error condition, ask your HP support
representative for assistance. See “Calling the HP support center” on
page 40.
Troubleshooting
37
Error conditions
Depending on your system configuration, you may be able to view error
messages as follows:
• View SIMs in Command View (Device Health tab).
• View R-SIMs in Remote Control XP, including reference codes and
severity levels of recent R-SIMs.
• View SIMs that generate SNMP traps on the host.
Error Condition
Recommended Action
The logical devices are not
recognized by the host.
Verify that the READY indicator lights on the disk array are ON.
Verify that fiber cables are correctly installed and firmly connected.
Verify that the target IDs are properly configured. The LUNs for each
TID must start at 0 and continue sequentially without skipping any
numbers.
Verify that the TIDs/WWNs on each bus are unique. Do not install two
devices with the same ID on the same bus.
Recheck the buses for new devices.
Verify that the disk array Host Mode is set correctly.
The host does not reboot
If you power off the host without executing the shutdown process, wait
properly after hard shutdown. three minutes to allow the disk array’s internal timeout process to
purge queued commands. If the host restarts while the disk array is
processing queued commands, the host may not reboot successfully.
Volumes cannot be created.
Verify that the disk array logical devices are correctly formatted.
Verify with the appropriate utility (MAPPER or fcscan) that disk array
devices are recognized by the host system.
Verify all components of the SYSGEN I/O configuration pertaining to
the disk arrays.

Disk array device emulations
43
Note 1:
The availability of a disk type depends on the disk array.
Note 2:
The devices are defined to the host as SCSI disk devices, even though the
interface is Fibre Channel.
Note 3:
The device capacity can sometimes be changed by the BIOS or host adapter
board. This may make actual capacity different from that listed in the table.
Note 4:
The number of blocks for a CVS volume is calculated as follows:
# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)
Example 1: For an OPEN-3 CVS volume with capacity = 37 MB:
# of blocks = (53 cylinders–see Note 5) × (15 heads) × (96 sectors per
track) = 76320
Example 2: For an OPEN-V CVS volume with capacity = 49 MB:
# of blocks = (53 cylinders–see Note 5) × (15 heads) × (128 sectors per
track) = 101760
Note 5:
The number of cylinders for a CVS volume is calculated as follows
(↑ …↑ means that the value should be rounded up to the next integer):
OPEN-3/8/9/E: The number of cylinders for a CVS volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 1024/720 ↑
Example: For an OPEN-3 CVS volume with capacity = 37 MB:
# of cylinders = ↑ 37 × 1024/720↑ = ↑ 52.62↑ (rounded up to next
integer) = 53 cylinders
OPEN-V: The number of cylinders for a CVS volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 16/15 ↑
Example: For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders = ↑ 49 × 16/15↑ = ↑ 52.26↑ (rounded up to next integer)
= 53 cylinders
OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 1024/720 ↑ × n
44
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
Example: For a CVS LUSE volume with capacity = 37 MB and n = 4
# of cylinders = ↑ 37 × 1024/720↑ × 4 = ↑ 52.62↑ × 4 = 53 × 4 = 212
OPEN-V: The number of cylinders for a CVS LUSE volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 16/15 ↑ × n
Example: For an OPEN-V CVS LUSE volume with capacity = 49 MB and
n=4
# of cylinders = ↑ 49 × 16/15↑ × 4 = ↑ 52.26↑ × 4 = 53 × 4 = 212
Note 6:
Disk array device emulations
The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not
number of cylinders. The capacity of an OPEN-V CVS volume can be
specified in MB or number of cylinders. You set the volume size using the
LUN Configuration Manager or Command View software.

Booting from the array
In order to use a native Fibre Channel-connected disk array as MPE/iX
Ldev 1 (the boot disk) to load, boot, and run the OS software, you must
know the primary I/O boot path leading to the desired LUN in the XP disk
array. The primary boot path must be set into PDC memory so that the
processor will be able to perform I/O to the disk device during system boot
operations.
You can use one of three methods to determine the primary boot path for
your disk array LUN, depending on the particular situation. These methods
are summarized at the start of this appendix and are explained in detail on
the page referred to in the summary.
Booting from the array
47
1. Existing MPE/iX 7.5 boot disk is available (page 50):
If the system already has an MPE/iX Release 7.5 OS installed on an
existing disk device (internal or external SCSI disk), use the following
procedure.
• Boot and run the OS from the existing Ldev 1 boot disk.
• Use the fcscan –h utility program for native Fibre Channel I/O path
mapping. This will give you the BOOT MENU PATH for all of the
native Fibre Channel attached disk array devices.
• Select the desired disk array LUN to be your new Ldev 1.
• Use the BOOT MENU PATH from fcscan as the primary boot path.
2. No existing MPE/iX boot disk available and disk array is direct Fibre
Channel connected (page 53):
If the system does not already have an MPE/iX Release 7.5 OS
installed, and the disk array you want to use for MPE/iX Ldev 1 is
native Fibre Channel and directly cabled to the host HP e3000 system
(no Fibre Channel switch), then use the following procedure.
• Use the MAPPER2 I/O mapping utility of the ODE (Offline
Diagnostic Environment) to display the boot menu I/O paths for all
of the LUNs of that disk array. MAPPER2 will correctly detect and
report the paths for a direct-Fibre-Channel-connected disk array.
• Boot the system from the SLT (System Load Tape) on the alternate
boot path
• Run ODE>MAPPER2.
• Select the desired disk array LUN to be your new Ldev 1, and use the
I/O path reported by MAPPER2 to be the primary boot path.
• Install the OS onto the new Ldev 1.
3. No existing MPE/iX boot disk available and disk array is Fibre Channel
switch connected (page 55):
If the system does not already have an MPE/iX Release 7.5 OS
installed and the disk array you want to use for MPE/iX Ldev 1 is
48
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
SAN-connected (through a Fibre Channel switch) to the host HP
e3000 system, then use the following procedure.
• You CANNOT use the MAPPER2 facility to determine the I/O paths
for the disk array. MAPPER2 will not be able to recognize and report
the LUNs of the disk array on the Fibre Channel switch.
• You must use web browser access via LAN to the Fibre Channel
switch to determine the I/O path to use for the primary boot path.
The remainder of this appendix gives more detailed procedures, illustrated
with actual examples, for these three methods of determining the primary
boot path and loading the OS software onto a native Fibre Channel
connected disk array.
Booting from the array
49
Existing MPE/iX 7.5 boot disk is available
If an existing MPE/iX boot disk is available, simply boot and start the
system from the existing boot disk in normal fashion.
When the system is up, run the fcscan –h command to find and display the
I/O paths for the newly connected disk array devices.
NOTE: Before you can run fcscan to find the paths for the disk array
devices, you must configure the native Fibre Channel HBAs used to
connect the disk arrays to the MPE/iX I/O system configuration. The
fcscan command depends on finding the Fibre Channel HBAs in the
existing system configuration in order to perform its search for attached
disk array devices.
Follow this procedure if you have an existing boot disk:
1. Boot and start the existing system normally from the existing boot disk.

No existing MPE/iX boot disk available and disk
array is direct Fibre Channel connected
If you have no boot disk available and the disk array is direct Fibre Channel
connected, you can use the MAPPER2 utility while the system is booted
from the SLT tape on the alternate boot path. MAPPER2 will locate and
display the boot menu I/O paths for the directly Fibre Channel attached disk
arrays. You choose the desired disk array LUN from the MAPPER2 output
to become the new MPE/ix Ldev 1 boot disk, and then use the MAPPER2
I/O path to set the system’s primary boot path for loading the OS.
Follow this procedure and example to use MAPPER2 to set the boot
path:
For brevity, only an excerpt of the MAPPER2 output is shown.

HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
No existing MPE/iX boot disk available and disk
array is Fibre Channel switch connected
If you have no boot disk and the array is connected to a Fibre Channel
switch, the MAPPER2 utility CANNOT be used to determine the I/O paths
for the disk array devices. Instead, you need to derive the primary boot path
information from the known I/O path of the A6795A Fibre Channel HBA
(recorded at hardware installation time) and the known configuration of
LUNs within the disk array (established earlier with Command View XP or
LUN Configuration Manager). Additional path information must be
obtained by LAN connection of a suitable web browser to the Fibre
Channel switch.
Primary boot path format for Fibre Channel devices
In order to form the desired primary I/O boot path for the disk array to be
used as Ldev 1, you will be combining three parts of the I/O path to make
the whole I/O path in the format required by processor PDC for boot paths:
• The part of the I/O path that belongs to the A6795A Fibre Channel
HBA, plus
• The part of the I/O path that belongs to the disk array’s Fibre Channel
interface (the N-Port), plus
• The part of the I/O path that gives the SCSI target ID and LUN
information for a LUN within the disk array.
PDC on A-Class and N-Class systems requires the following format for
combining these I/O path parts:
|-- HBA I/O Path Part --|--- FC N-Port I/O Path Part---|- SCSI LUN I/O Path Part-|
BC / BC / BC / Card . Domain . Area . Port . Bus# . Target ID . LUN
0 / 6 / 0 /
0
.
1
.
20
.
44
.

.

You should already know the HBA I/O path, recorded when the HBA
hardware was installed and also the SCSI LUN I/O path. The following
section explains how to use a web browser to determine the FC N-Port I/O
path needed to complete the whole primary boot path.
Booting from the array
55
Determining the FC N-Port I/O path
Using a web browser, navigate to the address of your Fibre Channel switch,
where you will see a display similar to the one below. Details may differ
depending on switch model and firmware level. Look for the “Name
Server” control button. In the example below, it is the third button down
from the top on the left side of the display.
Click on the Name Server button to access the Name Server display, and
the switch will present a display a name server table similar to the one that
follows:
56
HP StorageWorks Disk Array XP Operating System Configuration Guide: MPE/iX
You should already know the port number of the plug-in port on the Fibre
Channel switch where you have connected the disk array. If you need to,
trace the Fibre Channel cable from the disk array to the switch and
determine the port to which the array is connected. In the example figure
above, the disk array is connected to pors 5 of the switch. You will notice
the disk model information in the “Symbolic Name” portion of the Name
Server display, at the right on the line for Port # 5.
The Port ID column of the display has the information needed to form the
FC N-Port part of the I/O path. The Port ID is a 6-character hexadecimal
digit (3 bytes) that decomposes into the three portions (Domain.Area.Port)
of the FC N-Port part of the I/O path. Since PDC boot paths are set as
decimal numbers, these three portions of FC N-Port value have to be
converted from hex to decimal before you can use them to set the primary
boot path.
Example for Port #5, Port ID 011532
In the Name Server display above, the disk array on Port 5 has Port ID =
011532, hexadecimal. To convert this to the FC N-Port format required by
PDC, break apart the 6 digit hex number into its 3 hex bytes, and convert
Booting from the array
57
each hex byte to its decimal equivalent. The resulting three decimal
numbers become the FC N-Port (Domain.Area.Port) portion of the primary
boot path:
• 011532 hex Æ 01 15 32
• 01 hex Æ 01 decimal
• 15 hex Æ 21 decimal
• 32 hex Æ 50 decimal
so the FC N-Port portion of the I/O path is 1.21.50.
Composing the entire primary I/O boot path
You can now form the entire primary I/O boot path for PDC by combining:
• the HBA part of the path, 0/6/0/0
• the FC N-Port part of the path, 1.21.50
• your selected SCSI LUN within the disk array, for this example: 0.0.2
(bus.target.lun)
to get the complete primary I/O boot path 0/6/0/0.1.21.50.0.0.2.
Now set the system’s primary boot path to that value, and then install the
OS from the SLT tape.
When you are finished loading the OS, return to the main body of this
manual at the “Configure the disk array devices in MPE/iX” (page 28).

As it relates to MPE/iX, Ldev refers to an MPE logical device
synonymous with an MPE volume member, MPE device or LUN
created under the control of MPE/iX's SYSGEN utility program.
LDEV
Logical device. An LDEV is created when a RAID group is divided into
sections using a selected host emulation mode (for example, OPEN-9 or
OPEN-M). The number of resulting LDEVs depends on the emulation mode.
“LDEV” and “volume” are synonyms.
LUN
Logical unit number. A LUN results from mapping a SCSI logical unit
number, port ID, and LDEV ID to a RAID group. The size of the LUN is
determined by the emulation mode of the LDEV and the number of LDEVs
associated with the LUN. For example, a LUN associated with two OPEN3 LDEVs has a size of 4,693 MB.
LUSE
