14 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Installation

You and your HP service representative each play a role in installation. Your HP service representative is responsible for installing the disk array and formatting the disk devices. You are responsible for configuring the host server for the new devices with assistance from your HP service representative.

Installation 15

Features and requirements

Ask your HP service represent ative about the lat est supporte d hardware and software.

The disk array and host have the following features:

• Storage capacity. The storage capacity for each model is listed

below:

XP128: From 8 to 128 drives for up to 18 TB, 48 FC ports XP1024: From 8 to 1024 drives for up to 149 TB, 64 FC ports XP10000: Up to 240 drives for up to 69.2 TB, 48 FC ports XP12000: Up to 1152 drives for up to 165 TB, 128 FC ports

• Server support. HP-UX-supported processor

• Operating system support. HP-UX, version 10.20, 11.0, or 11i v2

with the latest patches (if any)

Before installing the disk array, ensure the environment conforms to these requirements:

• Host Bus Adapters (HBAs) Install HBAs and all utilities and

drivers. Refer to the adapter documentation for installation details.

• (Recommended) HP StorageWorks Remote Web Console XP,

Command V iew XP Advanc ed Editi on or Command View XP with LUN management feature for configuring disk array ports and paths

• (Recommended) HP StorageWorks LUN Configuration and

Security Manager XP

16 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Fibre Channel interface

The XP fami ly of disk arrays support s these Fibre Channel elements:

• (Optional) Other available XP software (some may not be supported by your array:

HP StorageWorks Business Copy XP HP StorageWorks Continuous Access XP HP StorageWorks Continuous Access Extension XP HP StorageWorks Auto LUN XP HP StorageWorks Data Exchange XP HP StorageWorks Resource Manager XP HP StorageWorks RAID Manager XP HP StorageWorks Cache LUN XP HP StorageWorks Auto Path XP HP StorageWorks Cluster Extension XP HP StorageWorks Performance Advisor XP

• Connection speed of 1 Gbps and 2 Gbps

• Short-wave non-OFC (open fiber control) optical interface

• Multimode optical cables with SC or LC connectors

• Public or private arbitrated loop (FC-AL) or direct fabric attach

• Fibre Chan nel switches

Even though the interface is Fibre Chann el, this gui de uses the term “SCSI disk” because disk array devices are defined to the host as SCSI disks.

Installation 17

Device emulation types

The XP family of disk arrays supports these device emulation types:

• OPEN-K/3/8/9/E devices: OPEN-x logical units represent disk

devices. Except for OPEN-V, these devices are based on fixed sizes. OPEN-V is a user-defined size. Supported emulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.

• LUSE devices (OPEN-x*n): Logical Unit Size Expansion (LUSE)

devices combine 2 to 36 OPEN-x devices to create expanded LDEVs larger than standard OPEN-K/3/8/9/E disk devices. For example, an OPEN-x LUSE volume created from ten OPEN-x volumes is designated as OPEN-x*10.

• CVS devices (OPEN-x CVS): Volume Size Configuration (VSC)

defines custom volumes (CVS) that are smaller than normal fixed-sized logical disk devices (volumes). (OPEN-V is a CVS-based custom disk size that you dete rmine. OPEN- L does not support CVS.)

• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS

combines CVS devices to create an expanded device. This is done by first creating CVS custom-sized devices and then using LUSE to combine from 2 to 36 CVS devices. For example, if three OPEN-9 CVS volumes are combined to create an expande d device, this device is designated as OPEN-9*3-CVS.

Failover

The XP family of disk arrays supports many standard software products that provide host, application, or I/O path failover and management.

The following are supported for HP-UX:

• HP Multi-C omputer/Serv iceGuard (MC/ServiceGuard) software for application failover

• Alternate link for I/O path failover (included in HP-UX)

• Logical volume management (included in HP-UX)

18 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

SNMP configuration

The XP family of disk arrays supports standard Simple Network Management Protocol (SNMP) for remotely managing the disk array. The SNMP agent on the SVP performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using Remote Web Console XP, Command View XP, or Command View XP Advanced Edition. Refer to the applicable user’s guide for procedures.

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, you use Remote Web Console, Command View, or Command View XP Advanced Edition to designate at least one LDEV as a command device. Refer to the app li cab le user’s guide f or information about how t o designate a command device.

Install and configure the disk array

The HP service represen tative perf orms these ta sks:

• 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 Remote Web Console, Command View, Command View XP Advanced Edition, or LUN Configuration and Securi ty Man ager to complete the remai ning t asks li sted below. If you do not have these programs, 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 must be set depending on the host you use. After the disk array is installed use LUN Manager in Remote Web Console XP (shown), Command View XP, or Command View XP Advanced Edition to set t he host mode f or e ach por t. The host mode se ttin g for HP-UX is 08.

Installation 21

For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE.

OFF: When the host scans the LUNS on the port, the disk array is represented in the d ev ice list for HP-UX.

Installation 23

Configuring the Fibre Channel ports

Configure the disk array Fibre Channel ports by using Remote Web Console (shown), Command View, or Command View XP AE. 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.

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.

24 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Fabric and Connection parameter settings

Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following table and figures. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide on the

hp.com

website.

Installation 25

Install and configure the host

This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk array.

Loading the OS and software

Follow the manufacturer’s instructions to load the operating system and software onto the host. Load all OS patches and configuration utilities supported by HP and the HBA manufacturer.

Installing and configuring the HBAs

Install and configure the host bus adapters using the HBA manufacturer’s instructions.

26 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Clustering and fabric zoning

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.

Installation 27

Fabric zoning and LUN security for multiple operating systems

You can connect multiple clus te rs of various operating systems to the sa me switch and fabric using appropriate zoning and LUN security as follows:

• Host zones must contain only homogeneous operating systems.

• Storage port zones may overlap if more than one operating system

needs to sh are an array port.

• Heterogeneous operating systems may share an XP array port if you

use Secure Manager and set the appropriate host group and mode. All others must connect to a dedicated XP array port.

• Use Secure Manager for LUN i sol at io n when multiple hosts conne ct

through a shared array port. Secure Manager provides LUN security by allowing you to restrict which LUNs each host can access.

Connect the disk array

The HP service representative connects the disk array to the host by:

1. V eri fying operational sta tus of the disk array c hannel adapters, LDEVs, and paths.

2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.

3. Verifying the ready status of the disk array and peripherals.

Defining the paths

Use Remote Web Console (shown), Command View, or Command View XP AE to define paths (LUNs) between hosts and volumes in the disk array.

This process is also called “LUN mapping.” In Remote Web Console and Command View, LUN mapping includes:

• Configuring ports

• Setting LUN security

• Creating host groups

• Assigning host bus adapter WWNs to host groups

• Mapping volumes to host groups (by assigning LUNs)

Installation 29

In Command View XP AE, LUN mapping includes:

• Configuring ports

• Creating storage groups

• Mapping volumes and WWN/host access permissions to the storage groups

For details see LUN Configuration and Security Manager User’s Guide or Command Vi ew XP Advanced Editi on Device Manag er Web Client User’s Guide. Note the LUNS and t heir ports , WWNs, ni cknames, and LDEVs for later use in verifying host and device configuration.

30 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Verifying HBA installation

After configuring the ports on the disk array, verify that the HBAs are installed properly.

Use the ioscan –f command, and verify that the rows shown in the ex ample are displayed. If these rows are not di splayed, check the host adapter installation (hardware and driver installation) or the host configuration.

Example

# ioscan -f

Installation 31

Verifying device recognition

Verify that the HP-UX system recognizes the new devices on the disk array.

If the SCSI paths were defined after the system is powered on, you must halt and restart the system to allow the system to recognize the new devices.

To verify device recognition:

1. Log in to the system as root.

2. Display the device data to verify that the system recognizes the newly

installed devices on the disk array. Use the ioscan –fn command to display the device data.

On a system with a large LUN configuration, HP-UX may not build device files on all LUNs. Enter insf –e to build all mi ssing d evice file s.

3. Enter the device data for each disk array device in a table. See “Path worksheet” on page 62.

4. Construct the device file name for each device, using the device information, and enter the file names in your table. Use the following formula to construct the device file name:

cxtydz

where

x = SCSI bus instance number y = SCSI target ID z = LUN

c stands for controller, t stands for target ID, and d stands for device. The numbers x, y, and z are hexadecimal.

SCSI bus instance number Hardware path SCSI TID LUN File name

00 14/12.6.0 6 0 c6t0d0 00 14/12.6.1 6 1 c6t0d1

5. Verify that the SCSI TIDs correspond to the assigned port address for all connected ports ( see ma pping t ables on

page 63 in Appendix B, for

values). If so, the logical devices are recognized properly. If the logical devices are not recognized properly:

• Check the AL-PA for each port using the LUN Manager software.

• If the same port address is set for multiple ports on the same loop

(AL with HUB), all port addresses except one changed to another value, and the relationship between AL-PA and TID does not correspond to the mapping given in

Installation 33

Appendix B (page 63), set a

different address for each port, reboot the server, and then verify new device recognition again.

• If unused device information remains, the TID-to-AL-PA mapping will not correspond to the mappi ng given in

Appendix B (pag e 63). Renew the device information, and then verify new device recognition again.

34 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Configure disk array devices

Disk arrays are configured using the same procedure for configuring any new disk on the host. This includes the following procedures:

1. Verifying the device files and drivers (see page 36)

2. Creating the device files (see page 38)

3. Creating the physical volumes (see page 41)

4. Creating new volume groups (see page 42)

5. Creating logical volumes (see page 45)

6. Creating the file systems (see page 47)

7. Setting the I/O timeout parameter (see page 49)

8. Creating the mount directories (see page 50)

9. Mounting and verifying the file systems (see page 51)

10. Setting and verifying the auto-mount parameters (see page 52)

The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-x devices on the disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For further information on LVM configuration, see the HP-UX user documentation.

HP System Administrator Manager (SAM) can be used instead of UNIX commands to configure SCSI disk devices. See further information.

Installation 35

appendix C (page 73) for

Verifying the device files and drivers

The device files for new devices are usually created automatically during HP-UX startup. Each device must have a block-type device file in the /dev/dsk directory and a character-type device file in the /dev/rdsk directory.

However, some HP-compatible systems do not create the device files automatically. If verification shows that the device files were not created, follow the instruct ions i n device files manually.

This procedure verifies both types of device files.

To verify that the device files for the disk array devices were created:

1. Display the block-type device files in the /dev/dsk directory using the ls –l command with the output piped to more. Verify there is one

block-type device file for each disk array device.

2. Verify that the block-type device file name for each device is correct.

3. Display the character -type device fil es in the /dev/rdsk directory using the ls –l command with the output piped to more. Verify that there is one character-type device file for each disk array device.

Creating the device files

If the device files were not created automatically when the system was restarted, use th e insf – e command in the /dev director y to create t he devic e files. After this command i s exe cuted, repea t the proced ures in the pr evious section driver.

(page 36) to verify new device recognition and the device files and

Example

# insf -e

insf: Installing special files for mux2 instance 0 address 8/0/0

: : : :

Failure of the insf –e command indicates a SAN problem.

If the device files for the new disk array devices cannot be created automatically, you must create the device files manually using the mknod command as follows:

1. Retrieve the device information you recorded earlier.

2. Construct the device file name for each device, using the device information, and enter the file names in your table. Use the following formula to construct the device file name:

cxtydz

where

x = SCSI bus instance number y = SCSI target ID z = LUN

c stands for controller, t stands for target ID, and d stands for device. The numbers x, y, and z are hexadecimal.

38 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

3. Construct the minor number for each device, using the device information, and enter the file names in your table. Use the following formula to construct the minor number:

0xxxyz00

where

xx = SCSI bus instance number y = SCSI target ID z = LUN

4. Display the driver inform ation for the system using the lsdev command.

Example

# lsdev

Character Block Driver Class

: : : :

188 31 sdisk disk

5. Enter the major numbers f or the device drivers into the t able. Y ou should now have all required de vice and driver information in the table.

6. Create the device files for all disk array devices (SCSI disk and multiplatform devices) using the mknod command. Create the block-type device f iles in the /dev/dsk directory an d the charac ter-t ype device files in the /dev/rdsk directory.

# cd /dev/dskGo to /dev/dsk directory.

# mknod /dev/dsk/c2t6d0 b 31 0x026000

Create block-type file.

File name, b=block-type, 31=major #, 0x026000= minor #

# cd /dev/rdskGo to /dev/rdsk directory.

# mknod /dev/rdsk/c2t6d0 c 188 0x026000

Installation 39

Create character-type file.

File name, c=character-type, 177=major #, 0x026000=minor #

# The character-type device file is required for volumes used as raw

devices (for example, 33 90-3A/B/ C). Th e block- type devi ce fil e is no t required for volumes used as raw devices.

If you need to delete a device file, use the rm –i command.

Creating the physical volumes

A physical volume must be created for each new SCSI disk device.

To c reate the physical volum es:

1. Use the pvcreate command to create the physical volumes with the character-type device file as the argument. Specify the /dev/rdsk directory.

Example

# pvcreate /dev/rdsk/c6t0d0

Physical volume "/dev/rdsk/c6t0d0" has been successfully created.

# pvcreate /dev/rdsk/c6t0d1

Physical volume "/dev/rdsk/c6t0d1" has been successfully created.

Do not use the –f option with the pvcreate command. This option creates a new physical volume forcibly and overwrites the existing volume. If you accidentally enter the character-type device file for an existing volume, you will lose the data on that volume.

2. Repeat step 1 for each OPEN-x device on the disk array.

Installation 41

Creating new volume groups

You must create new volume groups for the new physical volumes. If desired, you can also add any of the volumes on the disk array to existing volume groups using the vgextend command. The physical volumes that make up one volume group can be located either in the same disk array or in other disk arrays.

To allow more volume groups to be created, use SAM to modify the HP-UX system kernel configuration. See

To create volume groups:

1. Use the vgdisplay command to display the existing volume groups.

2. Choose a unique name for the new volume group (for exa mple : vg06) .

3. Create the directory for the new volume group.

appendix C (page 73) for details.

Example

# mkdir /dev/vg06

4. Use the ls –l command (with the output piped to grep to display only

the files containing “group”) to display the minor numbers for the existing group files.

# ls –1 /dev/vg* | grep group

crw-rw-rw 1 root root 64 0x0000000 Nov7 08:13 group

5. Choose a unique minor number for th e new group file in sequential order (for example, when exi sting volume groups are vg00-vg05 and the next group name is vg06, use minor number 06 for the vg06 group file).

The minor numbers are hexadecimal (for example, the 10th minor number is 0x0a0000).

6. Use mknod to create the group file for the new directory. Specify the volume group name, major number, and minor number. The major number for all group files is 64.

42 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Example In this exampl e: gro up name = vg06, maj or number of group file = 64,

minor number of existing group file = 06 (which must be unique for each volume group), and c = character.

# mknod /dev/vg06/group c 64 0x060000 :

7. Create the volume group. To allocate more than one physical volume to the new volume group,

add the other physical volumes, separated by a space.

Example

# vgcreate /dev/vg06 /dev/dsk/c6t0d0

Volume group "/dev/vg06" has been successfully created.

Volume group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf.

For Logical Unit Size Expansion (LUSE) volumes that contain more than 17 OPEN-8/9 LDEVs or more than 7043 MB (OPEN-8/9*n-CVS), use the –s and –e physical extent (PE) parameters of t h e vgcreate command. See

“LUSE device parameters”

(page 68).

If you need to dele te a volume grou p, use the vgremove command (for example, vgremove /dev/vgnn). If the vgremove command does not work because the volume group is not active, use the vgexport command (for example, vgexport /dev/vgnn).

8. Use the vgdisplay command to verify that the new directory was created.

9. Use vgdisplay –v to verify that t he volume group was created correctly. The –v option displays the detailed volume group information.

Installation 43

Example

# vgdisplay –v /dev/vg06

- - - Volume groups - - -

VG Name /dev/vg06 VG Write Access read/write VG Status available Max LV 255 Cur LV 0 Open LV 0 Max PV 16 Cur PV 1 Act PV 1 Max PE per PV 1016 VGDA 2 PE Size (Mbytes) 4 Total PE 586 Alloc PE 0 Free PE 586 Total PVG 0

44 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Creating logical volumes

Use these commands for logical volume configuration:

lvremove Deletes a logical volume.

lvextend Increases the size of an existing logical volume.

lvreduce Decreases the size of an existing logical volume.

Caution Data within the file system can be lost after execution of lvreduce.

Any file system attached to the logical volume must be unmounted before executing the lvremove command.

Example:

Any file system attached to the logical volume must be unmounted before executing the lvreduce command.

Example:

lvremove /dev/vgnn/lvolx

lvextend –L size /dev/vgnn/lvolx

lvreduce –L size /dev/vgnn/lvolx

Create logical volumes after you create volume groups. A logical volume must be created for each new SCSI disk device

To c reate logical volumes:

1. Use the lvcreate –L command to create a logical volume. Specify the volume size (in megabytes) and the volume group for the

new logical volume. HP-UX assigns the logical volume numbers automatically (lvol1, lvol2, lvol3). Use the following capacity values for the size parameter:

OPEN-K = 1740 OPEN-3 = 2344 OPEN-8 = 7004 OPEN-9 = 7004 OPEN-E = 13888

Installation 45

OPEN-L = 34756 OPEN-V = 61432

To calculate S1 for CVS, LUSE, and CVS LUSE volumes, first use the vgdisplay command to display the physical extent size (PE Size) and usable number of physical extents (Free PE) for the volume. Calculate the maximum size value (in MB) as follows:

S1 = (PE Size) × (Free PE) Logical volumes can span multiple physical volumes. Use the

diskinfo command for extended LUNs.

Example Create an OPEN-3 logical volume the size of the physical volume,

using 2344 for the size parameter. An OPEN-9 volume uses 7040 for the size parameter to create a logical volume the size of the physical volume.

# lvcreate –L 2344 /dev/vg06

Logical volume "/dev/vg06/lvol1" has been successfully created with character device "/dev/vg06/rlvol1".

Logical volume "/dev/vg06/lvol1" has been successfully extended.

Volume Group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.cof.

2. Use the lvdisplay command to verify that the logical volume was

created correctly.

46 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Example

# lvdisplay /dev/vg06/lvol1

- - - Logical volume - - LV Name /dev/vg06/lvol1 VG Name /dev/vg06 LV Permission read/write LV Status available/syncd Mirror copies 0 Consistency Recovery MWC Schedule parallel LV Size (Mbytes) 2344 Current LE 586 Allocated PE 586 Stripes 0 Stripe Size (Kbytes) 0 Bad block on Allocation strict

3. Repeat steps 1 and 2 for each logical volume to be created. You can create only one logical volume at a time. However, you can

verify multiple logical volumes at a time.

Creating the file systems

Create the file system for each new logical volume on the disk array. The default file system types are:

• HP-UX OS version 10.20 = hfs or vxfs, depending on entry in the

/etc/defaults/fs file

• HP-UX OS version 11.0 = vxfs

• HP-UX OS version 11.i = vxfs

To create file systems:

1. Use the newfs command to create the file system using the logical volume as the argument.

Installation 47

Example

# newfs /dev/vg06/rlvol1

newfs: /etc/default/fs is used for determining the file system type

mkfs (hfs): Warning -272 sectors in the last cylinder are not allocated.

mkfs (hfs): /dev/vg06/rlvol1 - 2400256 sectors in 3847 cylinders of 16 tracks, 2547.9MB in 241 cyl groups (16 c/g, 10.22Mb/g, 1600 ig/g)

Super block backups (for fsck -b) at:

16, 10040, 20064, 30038, 40112, 50136, 60160, 70184, 80208, 90232, . . . 2396176

Example

# newfs /dev/vg06/rlvol1Create file system

newfs: / etc/default/fs is used for determining the file system type

mkfs (hfs): ...

7188496, 7198520, 7208544

# newfs -F vxfs /dev/vg06/rlvol1Specify file system type

# newfs -F hfs /dev/vg06/rlvol2

2. Repeat step 1 for each logical volume on the disk array.

48 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Setting the I/O timeout parameter

Set the I/O timeout value for each disk device to 30 seconds.

To change the I/O timeout parameter:

1. Verify the current I/O timeout value using the pvdisplay command:

Example

# pvdisplay /dev/dsk/c0t6d0

This causes current values to be displayed:

--- Physical volumes --PV Name /dev/dsk/c0t6d0 VG Name /dev/vg06 PV Status available Allocatable yes VGDA 2 Cur LV 1 PE Size (Mbytes) 4 Total PE 586 Free PE 0 Allocated PE 586 [OPEN-9] Stale PE 0 IO Timeout (Seconds) default [I/O timeout value]

2. If the I/O timeout value is not 30, change the value to 30 using the pvchange -t command:

# pvchange -t 30 /dev/dsk/c0t6d0

This result is displayed:

Physical volume "/dev/dsk/c0t6d0" has been successfully changed. Volume Group configuration for /dev/vg06 has been saved in /etc/lvmconf/vg06.cof

3. V eri fy that the new I/O timeou t value is 30 seconds using the pvdisplay command:

Example

# pvdisplay /dev/dsk/c0t6d0

Current values are now displ ayed, confirming that the new I/O timeout value is 30 seconds:

Installation 49

--- Physical volumes --PV Name /dev/dsk/c0t6d0 VG Name /dev/vg06 PV Status available : Stale PE 0 IO Timeout (Seconds) 30 [New I/O timeout value]

4. Repeat the above steps for each new di sk that is connected to the system.

Creating the mount directories

Create a mount directory for each logical volume. Choose a unique name for each mount directory that identifies the logical volume.

Example The following example shows the root directory as the location for the

mount directories.

To create a mount directory for each logical volume:

1. Use mkdir with the new mount directory na me as the argument to create

the mount directory.

# mkdir /AHPMD-LU00

2. Use the ls –x command to verify the new mount directory.

# ls -x

AHPMD-LU00 bin dev device etc export

floppy home hstsboof kadb kernel lib

3. Repeat steps 1 and 2 for each logical volume on the di sk array.

50 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Mounting and verifying the file systems

After the mount directories have been created, mount and verify the file system for each logical volume.

To mount and verify the file systems:

1. Use mount to mount the file system for the volume.

Example

# mount /dev/vg06/lvol1 /AHPMD-LU00

2. Repeat step 1 for each logical volume on the disk array. If you need to unmount a file system, use the unmount command.

3. Use the bdf command to verify that the file systems are correct. The capacity is listed under Kbytes.

# bdf Filesystem Kbytes used avail %used Mounted on /ldev/vg00/lvol1 59797 59364 0 100% / : /ldev/vg06/lvol1 2348177 9 2113350 0% /AHPMD-LU00

4. As a final verification, perform some basic UNIX operations (for example file creation, cop yin g, and delet ion) on ea ch logic al device to make sure that the devices on the disk array are fully operational.

#cd /AHPMD-LU00

#cp /bin/vi /AHPMD-LU00/vi.back1

#ls -l

drwxr-xr-t 2 root root 8192 Mar 15 11:35 lost+found

-rwxr-xr-x 1 root sys 217088 Mar 15 11:41 vi.back1

#cp vi.back1 vi.back2

#ls -l

Installation 51

drwxr-xr-t 2 root root 8192 Mar 15 11:35 lost+found

-rwxr-xr-x 1 root sys 217088 Mar 15 11:41 vi.back1

-rwxr-xr-x 1 root sys 217088 Mar 15 11:52 vi.back2

Setting and verifying the auto-mount parameters

Set up and verify the auto-mount parameters for each new volume. The /etc/checklist file (which can also be cal l ed the /etc/fstab file) contains the auto-mount parameters for the logical volumes.

To set up and verify the auto-mount parameters:

1. Edit the /etc/checklist (/etc/fstab) file to add a line for each

OPEN-x device on the disk arra y . This example an d the following tabl e show the auto-mount parameters.

Example

#cp -ip /etc/checklist /etc/checklist.standard #vi /etc/checklist

/dev/vg00/lvol1 / hfs rw 0 1 # root /dev/vg00/lvol2 swap ignore rw 0 0 # primary swap : /dev/vg06/lvol1 /AHPMD-LU00 hfs defaults 0 2 # AHPMD-LU00 /dev/vg06/lvol2 /AHPMD-LU01 hfs defaults 0 2 # AHPMD-LU01

SCSI TID map for Fibre Channel adapters

When an arbitrated loop (AL) is established or reestablished, the port addresses are assigned automatically to prevent duplicate TIDs. With the SCSI over Fibre Channel protocol (FCP), there is no longer a need for target IDs in the traditional se nse.

SCSI is a bus-oriented protocol requiring each device to have a unique address since all commands go to all devices. For Fibre Channel, the AL-PA is used instead of the TID to direct packets to the desired destination.

Unlike traditional SCSI, when control of the loop is acquired, a point-to-point connection is established from initiator to target. To enable transparent use of FCP, the operating system maps a TID to each AL-PA.

The host maps SCSI protocol to Fibre Channel protocol and detects and accesses Fibre Channel-connected devices using device files (/dev/dsk/c*t*d* and /dev/rdsk/c*t*d*) in the same way as for SCSI-connected devices. The device files for Fibre Channel-connected devices are configured in a different way from SCSI-connected devices, because Fibre Channel supports 126 addresses per path while SCSI supports 16 TIDs per path.

The following table identifies the fixed mappings between the TID (drive) values assigned by the operating system and the Fibre Channel native addresses (AL_PA/SEL_ID) for Fibre Channel adapt ers. The controller number (the dks value in /dev/dsk/dks*d*l*s*) depends on the server configuration, and a different value is assigned per each column.

Disk array device emulations 71

The mapping cannot be done when these conditions exist:

• disk array devices and other types of devices are connected in the same loop

• information for unused devices remains in the server system

• multiple ports participate in the same arbitrated loop

Reference information for SAM

The HP System Administrator Manager (SAM) is used to perform HP-UX system administration functions, including:

• setting up users and groups

• configuring the disks and file systems

• performing auditing and security activities

• editing the system kernel configuration

This appendix provides instructions for:

• using SAM to configure the disk devices

• using SAM to set the maximum number of volume groups

Reference information for SAM 73

Configuring the devices using SAM

The SAM Areas window displays the system administration functions and allows you to select the desired function. The Disks and File Systems function allows you to configure new disk devices for LVM operations.

To configure the newly installed SCSI disk devices:

1. Select Disks and File Systems, then select Disk Devices.

74 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

2. V eri fy that the n ew disk array device s are displayed i n the Disk Devices

window.

3. Select the device to confi gure, select the Actions menu, select Add, and then select Using the Logical Volume Manager.

4. In the Add a Disk Using LVM window, select Create... or Extend a Volume Group.

5. In the Create a Volume Group windo w, enter the name of the new or existing volume group to assign the new device to, and then click OK twice. The Add a Disk Using LVM window now displays the volume group name.

6. Select Add New Logical Volume to open the Create New Logical Volumes window.

7. In the Create New Logical Volumes window, enter the name, size in megabytes, and mount directory for the new logical volume. Select Add, and then click OK twice.

8. Repeat steps 3 through 7 for each new disk device on the disk array.

Reference information for SAM 75

Setting the maximum number of volume groups using SAM

The HP-UX kernel specifies the maximum number of volume groups that can be created. The default is 10. You may need to change this number to accommodate new devices on the disk array. To change this number, use the Kernel Configuration function.

To change the maximum number of volume groups:

1. Select the Kernel Configuration f unction, then select Configurable Parameters.

2. In the Configurable Parameters window, select the maxvgs parameter, select the Actions menu, and then select Modify Configurable Parameter.

3. In the Modify Configurable Parameter window, enter the desired maximum number of volume groups in the Formula/Value field, and then click OK.

4. In the Configurable Parameters window, make sure that none of the parameters are selected. Then select the Actions menu, and select Create New Kernel.

5. When the configuration window opens, click Yes to create the new kernel (or click No to return to the Configurable Parameters window .)

6. When the Reboot the System window opens, click OK to move the new kernel into place and reboot the system.

78 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

LDEV Logical device. An LDEV is creat ed when a RAID group is carved into pieces

according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-L). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is o ften used synonymously wi th the t erm volume.

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 emulatio n 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 A LUN is normally associated with o nly a s ingle L DEV. The LUSE f eature

allows a LUN to be a ssociated with 1 to 36 LDEVs. Essentially , LUSE makes it possible for applica tions to access a single large poo l of storage. The LUSE feature is available when the HP StorageW orks LUN Configuration Manager product is installed.
