SGI IRIX INSTALLATION
The disk array comes with all hardware and cabling required for installation.
Installation of the disk array includes these activities:
• hardware installation
• remote console and LUN Configuration Manager installation
Hardware Installation
The HP service representative performs hardware installation as specified in the disk
array maintenance manual. Follow all precautions and procedures in the disk array
maintenance manual. Check all specifications to ensure proper installation and
configuration. Hardware installation involves several tasks:
1. Assemble all hardware and cabling.
2. Load the latest microcode and service processor (SVP) updates for full Fibre
Channel support.
3. Install and format the logical devices (LDEVs) using the SVP.
Make sure to get the desired LDEV configuration information from the user,
including the desired number of OPEN-K/3/8/9/E, CVS, LUSE, and
multiplatform (Data Exchange) devices.
Caution The SGI IRIX system can only recognize up to 32 LUs (per port). Make sure to
determine the number of disk array LUs based on this restriction.
4. Install the Fibre Channel adapters and cabling.
The total Fibre Channel cable length attached to each Fibre Channel adapter must
not exceed 500 meters (1,640 feet). Do not connect any open fibre control (OFC)
type connector to the disk array. Do not connect or disconnect Fibre Channel
cabling that is being actively used for I/O. This can cause the SGI IRIX system to
hang. Always confirm that the devices on the Fibre Channel cable are offline
before connecting or disconnecting the cable.

Fabric
Connect the disk array port to the F-port of the fabric switch. Connect the host adapter
to the FL-port of the fabric switch.
Disk Array FC Port
The Fibre Channel topology parameters for each disk array Fibre Channel port depend
on the type of device to which the disk array port is connected. Determine the topology
parameters supported by the device, and set your topology accordingly. The type of
disk array port is also important. See “Configuring the Disk Array Fibre Channel
Ports” (page 16).
Remote Console PC and LUN Configuration Manager Installation
The user or HP service representative can install the remote console PC and HP
Surestore LUN Configuration Manager XP. You will use the LUN Configuration
Manager software on the remote console PC to set the host modes for the disk array
ports and configure the Fibre Channel ports. For instructions on installing the LUN
Configuration Manager software, see the product manual:
HP Surestore LUN Configuration Manager XP: User’s Guide
If the LUN Configuration Manager software is not installed, the HP service
representative can use the SVP of the disk array to configure Fibre Channel ports.
Please contact your HP account team for further information on Fibre Channel
configuration services.

SGI IRIX Installation 11
Preparing for Disk Array Device Configuration
Before the disk array is connected to the SGI system, you must perform the following
tasks:
1. Set the host mode for the disk array SCSI (XP256) and Fibre Channel ports.
2. (Fibre Channel only) Configure the disk array Fibre Channel ports.
You use the LUN Configuration Manager Remote Control software to set the host
modes for the disk array ports and configure the Fibre Channel ports.
After completing these steps, you must:
1. Shut down the SGI system.
2. Connect the disk array.
3. Restart the SGI system.

(65.6 feet).
Differential SCSI
Adapters
Do not attach the disk array to any single-ended SCSI device. Ultra-wide differential or
fast-wide differential (FWD) adapters are recommended.
The logical devices are defined to the host as SCSI disk devices, whether the interface
is SCSI or Fibre Channel.
Fibre Channel Interface
Full-speed (100 MB/s) Fibre Channel interface, including shortwave non-OFC optical
interface, multimode optical cables with SC connectors, and gigabit link modules
(GLMs). For information on supported Fibre Channel adapters, hubs, and switches,
contact your HP service representative. The total Fibre Channel cable length attached
to each Fibre Channel adapter must not exceed 500 meters (1,640 feet). Do not connect
any OFC-type connector to the disk array.
Do not connect or disconnect Fibre Channel cabling that is being actively used for I/O.
Connectivity Options
The disk array has the following connectivity options. The all-open SCSI (XP256) or
Fibre Channel SCSI (XP512) configuration will be used by most HP customers.
•(XP256 only) SCSI

SGI IRIX Installation 13
The all-open system disk array is configured with all SCSI ports.
• Fibre Channel
Fibre Channel connections are supported, using a direct connection or using HP
Surestore SCSI Bridge FC bridges, hubs, and switches.
• multiplatform
The multiplatform disk array is configured with serial Enterprise System
Connection (ESCON), SCSI ports (XP256 only), or Fibre Channel ports.
Device Types
The disk array supports two types of devices:
• OPEN-K/3/8/9/E devices
These OPEN-K/3/8/9/E devices are used exclusively by the open-system hosts.
• LUSE devices
The Logical Unit Size Expansion (LUSE) feature of the disk array enables you to
configure custom-size logical units (LUNs), which are larger than standard
OPEN-K/3/8/9/E LUNs.

Prepare the Disk Array
To install the disk array, the HP service representative performs the following tasks:
1. Assemble final hardware.
2. Load the microprogram updates for SCSI/Fibre Channel support.
3. Install the SCSI or Fibre Channel adapters and cabling.
4. Install and format the logical devices using the disk array’s service processor (SVP).
Setting the Host Mode for the Disk Array Ports
The disk array ports have special modes that must be set for certain middleware
environments; for example, IRIS FailSafe or SGI Advanced Cluster Environment
(ACE) software. Use the LUN Configuration Manager software to set the host mode
for each port.
Figure 1. LUN Configuration Manager Set Host Mode Dialog Box
The required host mode setting for IRIX operations is 00.
Configuring the Disk Array Fibre Channel Ports
You must configure the disk array Fibre Channel ports to define the Fibre Channel
parameters and port addresses. Use the Fibre Parameter window in LUN Configuration
Manager to configure the disk array Fibre Channel ports.

SGI IRIX Installation 17
1. Select the appropriate settings for each Fibre Channel port based on the device to
which the port is connected.
2. Determine the topology parameters supported by the device, and set your topology
accordingly.
3. The type of port is also important. If you plan to connect different types of servers
to the array through the same fabric switch, you must use the zoning function of
the fabric switch.
Port Address
In fabric environments, the port addresses are assigned automatically by fabric switch
port number and are not controlled by the port settings. In arbitrated loop
environments, the port addresses are set by entering an arbitrated-loop physical address
Table 1. Fabric Parameter Settings on the Remote Console PC

(AL-PA) or loop ID. Table 6 (page 48) shows the available AL-PA values ranging from
01 to EF. Fibre Channel protocol uses the AL-PAs to communicate on the Fibre
Channel link, but the software driver of the platform host adapter translates the AL-PA
value assigned to the port to a SCSI target ID (TID).
Loop ID Conflict
The SGI system assigns port addresses from lowest (01) to highest (EF). To avoid loop
ID conflict, assign the port addresses from highest to lowest (that is, starting at EF).
The AL-PAs should be unique for each device on the loop to avoid conflicts. Do not
use more than one port address with the same TID in the same loop (for example,
addresses EF and CD both have TID 0).

SGI IRIX Installation 19
Define the SCSI Paths (XP256 Only)
Use the LUN Configuration Manager feature of the Remote Control software to define
the logical unit number (LUN) mapping (SCSI-to-LDEV paths) for the devices on the
disk array. If LUN Configuration Manager is not installed, the HP service
representative configures the LUN mapping using the disk array’s SVP.
Related Information For information about LUN Configuration Manager, see the product manual:
HP Surestore LUN Configuration Manager XP: User’s Guide
To define the SCSI paths for the new devices:
1. Use LUN Configuration Manager to define the port ID and topology parameters
for each Fibre Channel port. The Fibre Channel port ID takes the place of the SCSI
TID in a Fibre Channel environment. Current implementation limits connectivity
to eight LUNs per Fibre Channel port.
2. Use LUN Configuration Manager to define the SCSI paths for each new SCSI
device. Use only available TIDs and LUNs. Do not duplicate any TIDs or LUNs
on the SCSI buses.
Caution SCSI TID 7 is usually assigned to the SCSI initiator, SCSI TID 3 is usually assigned to
the boot device, and SCSI TID 6 is usually assigned to the CD-ROM device. Do not use
the TIDs assigned to these devices for any of the disk array devices.
3. The HP service representative verifies that the status of the SCSI/Fibre Channel
adapters and LDEVs is NORMAL and checks the SCSI/Fibre Channel path
configuration to make sure that all TIDs for the host system are unique.
4. Shut down and power off the system.

Connect the Disk Array
Some SGI systems may require you to use the System Maintenance Menu to start the
system.
To connect the disk array:
1. Before connecting the disk array, you must shut down and power off the SGI server
and all peripheral devices.
a. Shut down the SGI system as usual. For example, enter
shutdown –y –g0 –i0
b. When shutdown is complete, power off the SGI display.
c. Power off all peripheral devices.
d. Power off the SGI system.
2. Connect the disk array to the SGI system.
The HP service representative installs the SCSI or Fibre Channel cables between
the disk array and the SGI system. Be sure that SCSI terminators are installed as
required.
The HP service representative must use the disk array maintenance manual during
all installation activities. Follow all precautions and procedures in the
maintenance manual, and always check all specifications to ensure proper
installation and configuration.
3. Power on the SGI system and its peripheral devices.
a. Power on the SGI system display.
b. Power on all peripheral devices. The disk array must already be on, the host
modes must already be set, and the Fibre Channel ports must already be
configured. If the host modes or Fibre Channel ports are configured after the
SGI system is powered on, the system must be restarted.
c. Confirm the ready status of all devices.
d. Power on the SGI system.
