Removing the SWXRA-Yx from the Pallet
Use the following procedure to remove the SWXRA-Yx from the shipping pallet:
WARNING
Serious personnel injury may result if correct safety precautions are not taken during the removal procedure.
1. Attach the ramp to the shipping pallet by fitting the lip of the ramp into the groove on the pallet, as shown in Figure 1–3.
2. Lift the lock lever on each front caster to its up position so that the SWXRA-Yx enclosure can be moved.
Figure 1–3 Installation of Ramp on Shipping Pallet
WARNING
We recommend that three people be assigned to the task of unloading the SWXRA-Yx array from its shipping pallet. Failure to use sufficient personnel may result in personnel injury and equipment damage.
CAUTION
Do not drop the SWXRA-Yx array from a height of more than two inches, as serious structural damage can result.
3. Grasping the sheet metal base assembly, carefully lift the rear of the SWXRA-Yx enclosure over the “hump” in the center of the pallet and then roll the SWXRA-Yx enclosure off the pallet and down the ramp to the floor. If any further lifting of the
SWXRA-Yx is required, grasp the sheet metal base assembly on the side and lift it carefully.
4. Retain the shipping container and all packing materials.

Creating an Initial Controller Configuration
This chapter contains instructions for creating an initial configuration for your RAID Array Controller. It also briefly describes the CLI (Command Line Interpreter) and how to access it. The configuration steps include verifying the default configuration, adding drives, creating and initializing RAIDsets, STRIPEsets, MIRRORsets, and STRIPE MIRRORsets, identifying the storageset as a unit to the host, and verifying and recording your final configuration.
2.1
What is the CLI?
The Command Line Interpreter (CLI) is the user interface to the SWXRC–04 RAID Array
Controller. Using a connection between the controller’s maintenance port and a PC’s serial output port, the CLI can be used to view and modify the controller’s configuration. The CLI can also be used to access reports and diagnostic tools. This chapter specifies the CLI commands required to create an initial configuration for the controller.
See “Command Line Interpreter” in the SWXRC-04 RAID Array Controller User’s Guide for detailed descriptions of all CLI commands.
2.2
Accessing the CLI
Access the CLI using a PC with a terminal emulation program, such as the Microsoft
Windows Terminal program. You can also use most commercially-available communications programs.
2.2.1 Connect the PC to the Controller
Follow the steps below to connect the controller to a serial port on a PC.
1. Locate the connecting cable that came with the RAID subsystem. It has an RJ12 connector on one end and a 9-pin serial connector on the other end.
2. Plug the RJ12 connector into the jack on the controller.
3. Plug the serial connector into an available 9-pin serial port on the PC. If your PC does not have a 9-pin serial port, use the 9-pin to 25-pin adapter supplied with your
StorageWorks RAID Array 410 Subsystem. Note which serial port you used, since you will need that information in the communications program.
EK–SMRA4–IG. B01 2–1
Getting Started - RAID Array 410 for IBM AIX 3.2.5
2.2.2 Start the Communications Program
1. Start the communications program on your PC.
2. Set the communications program to use the serial port that is connected to the controller.
3. Set the communications parameters to:
•
9600 baud
•
8 bits
•
1 stop bit
•
No parity
2.2.3 Establish the Connection with the Controller
From your communication program, issue a connect command to establish a connection with the controller, and then press the Enter key. You should see the CLI prompt, which looks similar to
SWXRC>
2.3
Show Initial Configuration
The RAID Array 410 Subsystem has been preconfigured with a controller at ID0 (SCSI target 0) and a single drive logical unit D0.
Enter the following command to verify the controller’s parameters:
SWXRC> SHOW THIS_CONTROLLER FULL
The controller responds with a display similar to that shown below:

Chapter 2. Creating an Initial Configuration
Examine the display to verify the following information:
⊇
Controller SCSI target number should be 0
If the target number is not 0, use the following commands to set a SCSI target ID for the controller:
SWXRC> SET THIS_CONTROLLER ID=0
SWXRC> RESTART THIS_CONTROLLER
⊄
Cache condition should be GOOD
If the Cache condition is BAD then call your sales person for unit service or replacement of the Cache module.
⊂
Battery condition should be GOOD
If the Battery condition is LOW then allow the battery to charge with the subsystem power on for at least 6 hours. The battery must be fully charged to protect the data in the Write Back Cache. If the Battery condition is LOW after 6 hours of charging then call your sales person for unit service or replacement of the Batteries.
NOTE
The subsystem can be configured with the Battery condition LOW however the Write Back Cache cannot be initialized.
⊆ ∉
License key should be VALID
If the License key is INVALID then enter the following:
SWXRC> RUN FLS and follow the menu driven program to enable the license. You will need the WRITE-
BACK CACHE, RAID5, and MIRROR License Key page that is provided in the subsystem documentation package.
2.4
Dual–Redundant Controller Configuration
An optional controller and cache can be added to the SWXRC-04 RAID Array on the same host SCSI bus. This is called a dual-redundant controller configuration.
Dual redundant controllers offer automatic, intelligent failover of attached storage devices in the event of a controller failure. Up to four SCSI targets and 36 SCSI devices can be supported by the two controllers in a dual-redundant configuration
In a dual-redundant configuration, one terminal can set both controller configurations.
Installation procedures for the second controller can be found in Chapter 9 of the SWXRC-04
RAID Controller User’s Guide (EK-SMCS1-UG). After installation of both controllers, use the CLI to define the controllers’ parameters in the following order from a terminal connected to one controller:
Check the cache and battery conditions of the other controller using the following command:
SWXRC> SHOW OTHER_CONTROLLER FULL
EK–SMRA4–IG. B01 2–3

•
Cache condition should be GOOD
If the Cache condition is BAD then call your sales person for unit service or replacement of the Cache module.
Battery condition should be GOOD
If the battery condition is LOW, allow the battery to charge with the subsystem power on for at least 6 hours. The battery must be fully charged to protect the data in the
Write Back Cache. If the battery condition is still listed as LOW after 6 hours of charging, call your sales person for unit service or replacement of the batteries.
Set the controller SCSI target number:
SWXRC> SET THIS_CONTROLLER ID=0
SWXRC> SET THIS_CONTROLLER PERFERRED_ID=0
Enter the following command to copy parameters to the other controller – the one the terminal is not connected to:
SWXRC> SET FAILOVER COPY=THIS_CONTROLLER
SWXRC> RESTART OTHER_CONTROLLER
SWXRC> RESTART THIS CONTROLLER
Enter the following commands to verify the preceding parameters were set:
SWXRC> SHOW THIS_CONTROLLER FULL
SWXRC> SHOW OTHER_CONTROLLER FULL
2.5
Remove Default Logical Unit
The subsystem was configured at the factory with a single drive (DISK100) as a logical unit
(D0) available to the host. In order to configure the array, it is necessary to remove the logical unit. Use the following CLI command to do so.
SWXRC> DELETE D0
NOTE
The last character in the command is a zero, not the letter “oh”.
2–4 EK–SMRA4–IG. B01
Chapter 2. Creating an Initial Configuration
2.6
Add Disks to the Configuration
The CONFIG utility locates and adds disks to the controller. Run the CONFIG utility whenever you add new disks to the controller. Enter the following command to start the configuration utility. The disk numbers will correspond to the disk locations for your subsystem.
SWXRC> RUN CONFIG
The controller responds with a display similar to that shown below:
CONFIG LOCAL PROGRAM INVOKED
CONFIG IS BUILDING ITS TABLES AND DETERMINING WHAT DEVICES EXIST ON
THE SUBSYSTEM. PLEASE BE PATIENT.
ADD DISK110 1 1 0
ADD DISK200 2 0 0
ADD DISK210 2 1 0
ADD DISK300 3 0 0
ADD DISK310 3 1 0
ADD DISK400 4 0 0

ADD DISK530 5 3 0
ADD DISK600 6 0 0
ADD DISK610 6 1 0
ADD DISK620 6 2 0
ADD DISK630 6 3 0
CONFIG – NORMAL TERMINATION
In this example, the controller has located 17 new disks. Note that CONFIG did not list
DISK100 because the controller was already aware of that disk. The 3 digit number associated with each disk corresponds to Channel Number, Target Number and Controller
Logical Unit Number. The Controller Logical Unit Number will always be 0. DISK400, in this example, corresponds to the disk located on Channel 4, on controller Target 0, and
Controller Logical Unit 0. DISK510 corresponds to the disk located on Channel 5, controller
Target 1, and Controller Logical Unit 0. The following diagram shows the mapping of

2.7
Create a RAIDset
If you require RAIDsets to be available to the host as Logical Units, you must now combine disks into a RAIDset. RAIDsets must have at least three members, and can have as many as fourteen. This example creates two three member RAIDsets using the ADD RAIDSET command.
SWXRC> ADD RAIDSET RAID_SET_1 DISK100 DISK200 DISK300
SWXRC> ADD RAIDSET RAID_SET_2 DISK400 DISK500 DISK600
In this example, “RAID_SET_1” and “RAID_SET_2” are the names of the RAIDset, and they are followed by a list of disks to be included in each RAIDset. The names of the RAID sets are user selectable. Performance of your RAIDsets will be optimized if each RAIDset includes disks from different channels as shown in the example.
2.7.1 Initialize the RAIDset
Before you can put the RAIDset(s) into service, they must be initialized.
When you initialize a RAIDset, a chunksize must be specified. A chunksize is the number of blocks of data that is transferred at one time. By using the default chunksize, the controller will optimize the chunksize by selecting a number equal to the number of blocks in one track of disk data. We recommend using the default chunksize.
SWXRC> INITIALIZE RAID_SET_1 CHUNKSIZE=DEFAULT
SWXRC> INITIALIZE RAID_SET_2 CHUNKSIZE=DEFAULT
NOTE
Valid chunksizes are 16 – 682 blocks. You should use a larger chunksize for applications that make a lot of I/O requests. Use a smaller chunksize for applications that make relatively few I/O requests, but need to move large amounts of data with each request.
2.7.2 Add the RAIDset as a Logical Unit
To make a RAIDset available to the host computer, you must identify it as a host logical unit. The unit number is a one or three digit number preceded by “D”. The unit number identifies the controller’s target number and the RAIDset as the Logical Unit (LUN) connected to the target. Units identified with controller target number 0 have a single digit number which corresponds to LUN number. For example, D5 would be target 0, LUN 5.
Units identified with controller targets 1, 2 and 3 use a 3 digit number. The first digit corresponds to the controller target number, the second digit is always 0 and the third digit to the LUN number. For example, D205 would be target 2, LUN 5. You must now identify the
RAIDsets as Host Logical Units by using the ADD UNIT command.
SWXRC> ADD UNIT D0 RAID_SET_1
SWXRC> ADD UNIT D1 RAID_SET_2
This example uses the controller target of 0 (specified earlier with the
SET_THIS_CONTROLLER command) and LUN 0 and 1 as the digits in D0 and D1, since the two RAIDsets are the first and second units identified on the controller.

Chapter 2. Creating an Initial Configuration
NOTE
For the AIX operating systems, Logical Units must be sequential.
They must begin with D0 and be followed by D1, D2, D3, ..... etc.
2.7.3 Set Writeback Cache
The final step in creating the RAIDset is to enable the writeback cache. A single CLI command enables that feature for the entire RAIDset:
SWXRC> SET D0 WRITEBACK_CACHE
SWXRC> SET D1 WRITEBACK_CACHE
Where: D0 and D1 represent the host logical units of the RAIDsets described above.
2.8
Create a STRIPEset
If you require STRIPE sets to be available to the host as Logical Units, you must now combine disks into a STRIPEset. STRIPEsets must have at least two members, and can have as many as fourteen. This example creates a three member STRIPEset using the ADD
STRIPESET command.
SWXRC> ADD STRIPESET STRIPE_SET_1 DISK110 DISK210 DISK310
In this example, “STRIPE_SET_1” is the name of the STRIPEset, and it is followed by a list of the disks to be included in the STRIPEset. The names of the STRIPEsets are user selectable. Performance of your STRIPEsets will be optimized if each STRIPEset includes disks from different channels as shown in the example on page 2-5.
2.8.1 Initialize the STRIPEset
Before you can put the STRIPEset into service, it must be initialized.
When you initialize a STRIPEset, a chunksize must be specified. A chunksize is the number of blocks of data that are transferred at one time. By using the default chunksize, the controller will optimize the chunksize by selecting a number equal to the number of blocks in one track of disk data. We recommend using the default chunksize.
SWXRC> INITIALIZE STRIPE_SET_1 CHUNKSIZE=DEFAULT
NOTE
Valid chunksizes are 16 – 32768 blocks. You should use a larger chunksize for applications that make a lot of I/O requests. Use a smaller chunksize for applications that make relatively few I/O requests, but need to move large amounts of data with each request.
2.8.2 Add the STRIPEset as a Logical Unit
To make a STRIPEset available to the host computer, you must identify it as a host logical unit. The unit number is a one or three digit number preceded by “D”. The unit number identifies the controller’s target number and the STRIPEset as the Logical Unit (LUN) connected to the target. Units identified with controller target number 0 have a single digit
EK–SMRA4–IG. B01 2–7
Getting Started - RAID Array 410 for IBM AIX 3.2.5
number which corresponds to LUN number. For example, D5 would be target 0, LUN 5.
Units identified with controller targets 1, 2 and 3 use a 3 digit number. The first digit corresponds to the controller target number, the second digit is always 0 and the third digit to the LUN number. For example, D205 would be target 2, LUN 5. You must now identify the
STRIPEsets as Host Logical Units by using the ADD UNIT command.
SWXRC> ADD UNIT D2 STRIPE_SET_1
This example uses the controller target of 0 (specified earlier with the
SET_THIS_CONTROLLER command) and LUN 2 as the digit in D2, since the STRIPEset is the third unit identified on the controller.
NOTE
For the AIX operating system, Logical Units must be sequential.
They must begin with D0 and be followed by D1, D2, D3, ..... etc.
The final step in creating the STRIPEset is to enable the writeback cache. A single CLI command enables that feature for the entire STRIPEset:
SWXRC> SET D2 WRITEBACK_CACHE
Where: D2 represents the host logical unit of the STRIPEset described above.
2.9
Add Individual Disks as Logical Units
Before you can put an individual disk into service, it must be initialized:
SWXRC> INITIALIZE DISK410
SWXRC> INITIALIZE DISK510
If you require individual Disks to be available to the host as Logical Units, you must now identify the Disks as Host Logical Units by using the ADD UNIT command.
SWXRC> ADD UNIT D3 DISK410
SWXRC> ADD UNIT D4 DISK510
In this example, disks DISK410 and DISK510 were identified to the host as units D3 (Target
0, LUN 3) and D4 (Target 0, LUN 4) respectively.
NOTE
For the AIX operating system, Logical Units must be sequential.
They must begin with D0 and be followed by D1, D2, D3, ..... etc.
If a disk in a RAIDset goes bad, the controller will replace it with a disk from the Spareset, if one exists. If there is no Spareset, the RAIDset will run “reduced,” and you should replace the disabled disk as soon as possible. We recommend allocating one drive as a spareset.
If you chose to leave one or more drives as a Spareset for the RAIDset, you must now configure that in the controller. To create the Spareset, identify the drive(s) using the ADD
SPARESET command.
SWXRC> ADD SPARESET DISK610
In this example, DISK610 was identified to the controller as a Spareset.

2.10
Create a MIRRORset
If you require MIRRORsets to be available to the host as Logical Units, you must now combine disks into a MIRRORset. MIRRORsets must have at least two members, and can have as many as six. This example creates a two member MIRRORset using the ADD
MIRRORSET command.
SWXRC> ADD MIRRORSET MIRROR_SET_1 DISK120 DISK220
In this example, “MIRROR_SET_1” is the name of the MIRRORset, and it is followed by a list of the disks to be included in the MIRRORset. The names of the MIRROR sets are user selectable. Performance of your MIRROR sets will be optimized if each MIRRORset includes disks from different channels as shown in the example.
2.10.1 Initialize the MIRRORset
Before you can put the MIRRORset into service, it must be initialized.
SWXRC> INITIALIZE MIRROR_SET_1
2.10.2 Add the MIRRORset as a Logical Unit
To make a MIRRORset available to the host computer, you must identify it as a host logical unit. The unit number is a one or three digit number preceded by “D”. The unit number identifies the controller’s target number and the MIRRORset as the Logical Unit (LUN) connected to the target. Units identified with controller target number 0 have a single digit number which corresponds to LUN number. For example, D5 would be target 0, LUN 5.
Units identified with controller targets 1, 2 and 3 use a 3 digit number. The first digit corresponds to the controller target number, the second digit is always 0 and the third digit to the LUN number. For example, D400 would be target 4, LUN 0. You must now identify the
STRIPEsets as Host Logical Units by using the ADD UNIT command.
SWXRC> ADD UNIT D400 MIRROR_SET_1
This example uses the controller target of 4 and LUN 0.
NOTE
For the AIX operating system, Logical Units must be sequential.
They must begin with D0 and be followed by D1, D2, D3, ..... etc.
The final step in creating the MIRRORset is to enable the writeback cache. A single CLI command enables that feature for the entire MIRRORset:
SWXRC> SET D400 WRITEBACK_CACHE
Where: D400 represents the host logical unit of the MIRRORset described above.

If you require STRIPE MIRROR sets to be available to the host as Logical Units, you must now combine MIRRORsets into a STRIPEset. STRIPEsets must have at least two members, and can have as many as fourteen. These examples create 2, two member MIRRORsets using the ADD MIRRORSET command.
SWXRC> ADD MIRRORSET MIRROR_SET_3 DISK320 DISK420
SWXRC> ADD MIRRORSET MIRROR_SET_4 DISK520 DISK620
In these examples, “MIRROR_SET_3” and , “MIRROR_SET_4” are the names of the
MIRRORsets, and it is followed by a list of the disks to be included in the MIRRORsets.

Before you can put the MIRRORsets into a STRIPE MIRRORset, they must be initialized.
SWXRC> INITIALIZE MIRROR_SET_3
SWXRC> INITIALIZE MIRROR_SET_4
2.11.2 Create a STRIPE MIRRORset
To create the STRIPEset from the two MIRROR sets you must combine them into a
STRIPEset. STRIPE MIRRORsets must have at least two members, and can have as many as fourteen. This example creates a two member STRIPEset using the ADD STRIPESET command.
SWXRC> ADD STRIPESET STRIPE_MIRROR MIRROR_SET_3
MIRROR_SET_4
In this example, “STRIPE_MIRROR” is the name of the STRIPE MIRRORset, and it is followed by a list of MIRRORsets to include in the STRIPEset. The name of the STRIPEset is user selectable. Performance of your STRIPE MIRRORset will be optimized if each
MIRRORset includes disks from different channels.
2.11.3 Initialize the STRIPE MIRRORset
Before you can put the STRIPE MIRRORset into service, it must be initialized.

Installing the StorageWorks RAID Array 410
Software for IBM on AIX 3.2.5
This chapter describes the StorageWorks RAID Array 410 Software for IBM and the steps for installing it onto
IBM systems running AIX 3.2.5. The installation steps include organizing your system and existing files, loading the RAID software (diskette) onto your hard disk, and creating Logical Volume Groups and file systems.
NOTE
Prior to installing this software, ascertain that the RAID Controller
Write-Back Cache battery is fully charged. This is accomplished by supplying power to the RAID Controller for a minimum of 6 hours.
4.1
Installing the RAID Software for IBM on AIX 3.2.5
The procedures for installing the RAID Software for IBM on AIX 3.2.5 require you to be familiar with the System Management Interface Tool, SMIT. See the “System Management
Interface Tool” section in the System Management Guide: Operating System and Devices for more information on the use of SMIT.
Installing the RAID software on AIX 3.2.5 requires the following major steps:
•
Organizing Your System (Section 4.1.1)
•
Loading the RAID Array 410 Software onto the hard disk (Section 4.1.2)
•
Rebooting Your System (Section 4.1.3)
4.1.1
Organizing Your System
Perform the following procedures prior to installing the RAID Array 410 software:
CAUTION
DO NOT plug the SCSI cable into the RAID Array 410 connector at this time.
1. Reboot the system without the SCSI cable connected to the SWXRC-04 RAID Array
Controller. When the "console login" prompt appears, log into the system as root.
2. Ensure that the SCSI-2 Differential Fast/Wide Host Adapter, FC2416, has been installed in the system and configured by typing the following command and verifying the resulting display:
# lsparent -C -k scsi_scb -H && lsparent -C -k scsi

This command displays the SCSI adapters currently configured into the system. SCSI adapters with external SCSI expansion capability will have a -01 as the last field under the location column heading. If your system includes only one adapter with external expansion capability, then only one vscsi line will be displayed that contains a -01. If your system contains multiple adapters with external expansion capability, then multiple vscsi lines will be displayed as in the example above. If either no vscsi lines are displayed, or no vscsi line with a -01 location is displayed, then the operating system has not correctly configured the device. Recheck the hardware installation as described in Chapter 3 and retype this command.
Once you have determined that the vscsi device is configured correctly, check that the vscsi adapter with the -01 location is listed as "Available" in the status column. If the device is listed as "Defined" then the operating system has not correctly configured the device. In that case, recheck the hardware installation as described in Chapter 3 and retype this command.
3. Determine the following:
– SCSI target address of your RAID Array 410 controller configured in
Section 2.
– Number of consecutive Logical Unit Numbers (LUN’s) configured on the RAID
Array 410 controller.
4. Check for previously installed RAID software by typing:
# odmget -quniquetype=disk/scsi/SWXRC-04 PdDv
5. If you locate previously installed RAID software (previous command produces some output), delete the existing RAID software using the following commands:
# odmdelete -o PdDv -q uniquetype=disk/scsi/SWXRC-04
# odmdelete -o PdAt -q uniquetype=disk/scsi/SWXRC-04
# odmdelete -o PDiagAtt -q DType=SWXRC-04
# odmdelete -o PDiagDev -q Dtype=SWXRC-04
# odmdelete -o errnotify -q en_rtype=SWXRC-04
6. Install the BN31R-03 three-meter cable between the host adapter and the array subsystem. Route the right angle end connector end of the cable under the SWXRA-Yx
Subsystem enclosure and up through the front access hole nearest to the controller connector. Install the connector with the cable dressed to the right by firmly pushing it

Rebooting your computer
Proceed to Section 4.1.2.1 below for the media-specific instructions required to copy the distribution files from diskette.
4.1.2.1 Copying the File Archive from Floppy Diskette to Temporary Storage
Before the installation script can be run, the file archive that contains the RAID Array 410 software will need to be copied from the floppy diskette to a temporary directory. The installation script can then be extracted from the file archive and executed.
You will need approximately one MByte of temporary space to load from floppy disk.
1. Insert the RAID Array 410 software distribution diskette into the floppy drive.
2. Change the directory to a temporary storage area (/tmp). For example, type:
# cd /tmp
3. Create a directory into which the file archive can be loaded:
# mkdir swxrc
4. Change to that directory:
# cd swxrc
5. Extract the file archive from the diskette by entering the following command:
(Note: the name of /dev/fd0 may be different on your system.)
# tar xvf /dev/fd0
6. All of the files necessary to complete the RAID Array 410 Software installation have now been copied to this directory.

4.1.2.2 Executing the Installation Script
Perform the following procedure to install the RAID Array 410 software onto your system:
1. Enter the following command and press RETURN.
# ./stgwks_ra410_software_v10_aix.inst
2. The Copyright Notice and the following information should be displayed as follows:
Checking User...OK
Checking AIX Revision Level...OK
Checking for AIX patch for FC 2416 SCSI-2 Adapter...OK
Checking that SCSI-2 Adapter is installed and correctly configured
...OK
Checking for previous SWXRC software installation...OK
Checking for ODM add file...OK
Checking for ODM catalog file...OK
Once all of the checks have been successfully completed, the user will be asked about the
RAID Array 410 configuration. In order for the system to recognize the devices attached to the RAID Array 410, the Target ID (TID) and at least one Logical Unit Number (LUN) must have been created on the 410 via the Command Line Interface (CLI). The system can correctly configure the RAID Array 410 with multiple TID’s and multiple LUN’s per TID subject to the following restrictions:
•
LUN’s created for each TID must be consecutive with no gaps starting with LUN 0
•
When multiple TID’s have been created, the same number of LUN’s per TID must also have been created
•
If your computer system is equipped with two RAID Array 410 storage subsystems, the number of LUNs configured on each subsystem must be the same
•
If your computer system is equipped with multiple FC2416 Adapters, all of the restrictions above apply to each RAID Array 410 subsystem attached to each adapter
The following examples are allowable RAID Array 410 configurations as they will be correctly recognized and configured by the RS6000:
•
TID 4 and LUN 0
•
TID 4 and LUN 0 and LUN 1
•
TID 6 and LUN 0 and LUN 1 and LUN 2
•
TID 4 and LUN 0, TID 6 and LUN 0
The following examples are illegal RAID Array 410 configurations as they will not be correctly recognized and configured by the RS/6000:
•
TID 4 and LUN 5
•
TID 4 and LUN 5 and LUN 6
•
TID 6 and LUN 1 and LUN 4 and LUN 6
•
TID 4 and LUN 5, TID 6 and LUN 5

3. Answer the following prompt with the correct number of LUNs configured in your system and press RETURN.
Please enter the number of consecutive LUN's, 1..8, that have been configured on the RAID Array 410:
For the correct examples listed above, the answers to this question would be:
•
1
•
2
•
3
•
1
4. After the correct number of LUNs is entered, the installation script verifies that the answer is within the range of 1 through 8 and continues execution until the following information is displayed (Note: Processing time approximately 2 minutes):

RAID Array 410 Configuration Information name status location description hdisk3 Available 00-06-01-00 DEC SWXRC-04 RAID Array 410
This display lists the RAID Array 410 devices that have been configured into the system and recognized by the operating system.
Now that the RAID 410 is configured and the devices recognized by the operating system, the user is asked a series of questions regarding the use of those devices. Specifically, the user is asked whether to allow the script to create a default set of Logical Volume
Group(s).
The installation script determines the maximum amount of storage provided by the current set of devices attached to the RAID Array 410. The script creates a number of AIX file systems based on that size. The number of file systems created depends upon the amount of storage available. Each file system is created with the largest size possible under AIX version 3.2.5 which is approximately 2.0 GBytes. The last file system created contains the remaining amount of storage, consequently, that file system will be smaller than the others.
Once these file systems have been created, all of the usuable capacity currently installed in the RAID Array 410 will have been allocated. Therefore, it will not be possible to extend these file systems without adding additional devices to the RAID Array 410. If you wish
EK–SMRA4–IG. B01 4–7
Getting Started - RAID Array 410 for IBM AIX 3.2.5
to have the ability to extend the file systems without adding additional devices, you should answer N (No) to this question. That choice will allow you to create the Logical
Volumes and file systems with sizes smaller that those created by this script, thus allowing for future files-system extensions.
NOTE
Answering "Y" in the following step, will allow the installation script to create a default set of Logical Volume Groups, Logical
Volumes, file systems, and mount points for the devices attached to the RAID Array 410. This option is useful for users that are not familiar with the Logical Volume Manager and creation of a file system organization.
Answering "N" will cause the installation script to perform a small amount of cleanup and complete the installation, without creating any of the filesystem components necessary to utilize the RAID
Array 410 devices. This option is desirable for the user who understands how to utilize the Logical Volume Manager to tailor the file systems to their requirements.
5. Enter the answer to the following prompt and press RETURN:
Please answer Y/N (Yes or No) to the following question.
Would you now like to create the Logical Volume Group(s) that will contain the RAID Array 410 devices ?
The following messages are displayed only if the user answered "Y" to allow the installation script to create the default set of Logical Volume Group(s).
NOTE
Answering "1" in the following step will result in all of the devices listed under the “RAID Array 410 Configuration Information” display to be included in one Logical Volume Group.
Answering "2" will result in the creation of one Logical Volume
Group for each device listed under the "RAID Array 410
Configuration Information” display.
Beginning Logical Volume Group Creation...
This installation script can create two different types of Logical
Volume Groups. The script can:
1. Create a Logical Volume Group which contains all of the RAID Array
410 devices currently configured, or
2. Create one Logical Volume Group for each individual RAID Array 410 device that is currently configured.
Please specify 1 or 2:

Chapter 4. Software Installation
6. Enter 1 or 2 depending how your RAID array is configured and how you would like your storage organized and press RETURN.
7. If "1" is entered, all of the devices listed will be included in one Logical Volume Group as shown below. If "2" is entered, one new Logical Volume Group will be created for each device configured on the RAID Array 410 as shown on the next page.
All Devices Included in One Logical Volume Group
A new Logical Volume Group will be created and all of the configured
RAID Array 410 devices will be added to that group.
