HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Installation

1

Installation

Installation of the HP StorageWorks Disk Array XP is performed by your

HP service representative and you. The HP service representative installs the disk array and formats the disk devices. You configure the host server for the new devices with assistance from the HP service representative.

11

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Fibre Channel interface

The XP48, XP128, XP512, XP1024, and XP12000 disk arrays support these 1 Gbps and 2 Gbps Fibre Channel interfaces:

• 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 fabric direct attach

• Fibre Channel switches

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.

Device emulation types

The disk arrays support the following device emulation types:

OPEN-x 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) allows you to combine 2 to 36 OPEN-x devices to create expanded

LDEVs larger than standard OPEN-x disk devices. For example, an

OPEN-x LUSE volume created from ten OPEN-x CVS 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 determine. 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 expanded device, this device is designated as OPEN-9*3-CVS.

Installation

13

Failover

The disk arrays support many standard software products that provide host, application, or I/O path failover and logical volume (storage) management.

SNMP configuration

The disk arrays support standard Simple Network Management Protocol

(SNMP) for remotely managing 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. To configure the SNMP manager on the host, refer to the operating system documentation.

RAID Manager command devices

RAID Manager manages Business Copy (BC) and/or Continuous

Access (CA) operations from a server host. To use RAID Manager with BC or CA, you must use Command View or LUN Configuration

Manager to designate at least one 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.

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 for AIX is OF.

Installation

19

Install and configure the host

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.

Supported HBAs

Supported HBAs include the IBM FC6227, IBM FC6228, and IBM

FC6239.

To check whether the drivers are installed:

Example (FC 6227)

1. Use the lslpp command to display the drivers currently installed on the system.

# lslpp -l | grep df1000f7

2. Check the list for the required two drivers:

For the IBM FC 6227 HBA, the following drivers are required:

devices.pci.df1000f7

devices.fcp.disk

If the drivers are displayed, you do not need to install the drivers.

If the drivers are not displayed, install the drivers by using the installp command or SMIT.

20

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Example (FC 6228)

1. Use the lslpp command to display the drivers currently installed on the system.

# lslpp -l | grep df1000f9

2. Check the list for the required two drivers:

For the IBM FC 6227 HBA, the following drivers are required:

devices.pci.df1000f9

devices.fcp.disk

If the drivers are displayed, you do not need to install the drivers.

If the drivers are not displayed, install the drivers by using the installp command or SMIT.

To check the firmware level:

The HBA should have the proper version of firmware installed.

Example

1. Use the lsdev command to display the device object.

# lsdev -Cc adapter

2. Use the lscfg command to display the firmware level.

# lscgfg -vl fcsX fcsX is the fiber devids object (typically fcs0). The field “Devices

Specific.(Z9)” shows the installed firmware revision of the HBA.

To install the drivers using the AIX command line:

1. Insert the IBM drivers CD.

2. Use the installp command to install the drivers.

Example

# installp -a -dlpfc.installp all

3. Use the lslpp command to verify that the drivers are installed on the system.

4. Configure the new devices by rebooting the system with the

shutdown –r command or using the cfgmgr command to run

Configuration Manager.

Installation

21

To install the drivers using SMIT:

1. Insert the IBM drivers CD.

2. Start SMIT.

8. Check installation summary result (SUCCESS).

9. Press F10.

10. Use the smit devinst command to configure the devices.

22

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

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.

Installation

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.

23

Fabric zoning and LUN security for multiple operating systems

Environment

Standalone SAN

(non-clustered)

Clustered SAN

Multi-Cluster

SAN

By using appropriate zoning and LUN security, you can connect multiple clusters of various operating systems to the same switch and fabric:

• Host zones must contain only homogeneous operating systems.

• Storage port zones may overlap if more than one operating system needs to share 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 isolation when multiple hosts connect through a shared array port. Secure Manager provides LUN security by allowing you to restrict which LUNs each host can access.

24

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Connect the disk array

Connect the disk array to the host as follows:

1. The HP service representative verifies operational status of the disk array channel adapters, LDEVs, and paths.

2. The HP representative connects the Fibre Channel cables between the disk array and the fabric or host.

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

Installation

25

Defining the paths

Use Command View (shown) or LUN Configuration Manager to create paths (LUNs) between hosts and volumes in the disk array, also called LUN mapping. LUN mapping includes these tasks:

• Configuring ports

• Setting LUN security

• Creating host groups by operating system and setting their host modes

• Assigning host bus adapter WWNs to host groups.

• Mapping volumes to host groups (by assigning LUNs).

For details, see the Command View or LUN Configuration Manager guide.

HP recommends that you note LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.

26

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Verifying disk array device recognition

Verify that the host recognizes the disk array devices:

1. Log into the host as an administrator (root).

2. If the disk array LUNs are defined after the IBM system is powered on, issue a cfgmgr command to recognize the new devices.

3. Use the lsdev command to display system device data and verify that the system recognizes the newly installed devices.

# lsdev -Cc disk

The devices are listed by device file name. All new devices should be listed as “Available.” If they are listed as “Define,” you must do more configuration before they can be used.

Example

(Fibre Channel)

Example

#lsdev -Cc disk hdisk0 Available 10-60-00-5, 0 16 Bit SCSI Disk Drive hdisk1 Available 10-60-00-6, 0 16 Bit SCSI Disk Drive

The example shows that Device hdisk0 is installed on bus 60 and has

TID=5 and LUN=0.

4. Record the device file names for the new devices. You will use this information in changing the device parameters.

5. Use the lscfg command to find out the AIX disk device’s corresponding array LDEV designation.

# lscfg –vl hdisk3

In this example, the emulation type, LDEV number, CU number and array port designation should all be displayed for disk device hdisk3.

Installation

27

Configure disk array devices

Configure the disk array devices in much the same way you would configure any new disk on the host. Creating scripts to configure all devices at once may save you considerable time.

Changing the device parameters

When the device files are created, the system sets the device parameters to the system default values. You may need to change a few of those values for each new OPEN-x device:

• read/write (R/W) timeout value

• queue depth

• queue type

The recommended queue depth settings may not provide the best I/O performance for your system. You can adjust the queue depth setting to optimize the I/O performance of the disk array

.

To show the device parameters using the AIX command line:

At the command line prompt, enter lsattr -E -l hdiskx, where hdiskx is the device file name.

Example

# lsattr –E -l hdisk2

To change the device parameters using the AIX command line:

1. Change the parameters as follows:

To change the R/W timeout parameter, enter:

chdev –1 hdiskx –a rw_timeout='60'

To change the queue depth parameter, enter:

chdev –l hdiskx –a queue_depth='x'

Installation

Example

where x is a value from the above table.

To change the queue type parameter, enter:

chdev –l hdiskx –a q_type='simple'

This example changes the queue depth for device hdisk3:

Example

# lsattr –E –l hdisk3

3. Repeat these steps for each OPEN-x device on the disk array.

Tip

The lsattr command also shows other useful information, such as LUN ID of the mapped LDEV, worldwide name of the disk array FC port, and

N-Port ID.

Another useful command for determining the slot position and port worldwide name of the HBA is the lscfg –v –l hdiskx command.

To change the device parameters using SMIT:

1. Start SMIT. (Optional) For an ASCII session, use the smit –C command.

Example

# chdev –l hdisk3 –a queue_depth='2'

2. Verify that the parameters for all devices were successfully changed.

Mounting and verifying the file systems

Mount the file systems and verify that the file systems were created correctly and are functioning properly.

To mount and verify the file systems:

1. Mount the file system. Enter:

mount mount_point_name

Example

# mount /vg01

2. Repeat step 1 for each new file system.

3. Use the df command to verify the size of the file systems. The capacity is listed in 512-byte blocks. To list capacity in 1024-byte blocks, use the

df –k command.

Example

# df

File system 512-blocks free %Used Iused %Iused Mounted on

/dev/hd4 8192 3176 61% 652 31% /

/dev/hd2 1024000 551448 46% 6997 5% /usr

/dev/lv02 14401536 13949392 4% 16 1% /VG02 (OPEN-9)

4. Verify that the file system is usable by performing some basic operations

(for example, file creation, copying, and deletion) on each logical device.

Example

# cd /hp00

# cp /smit.log /hp00/smit.log.back1

# ls -l hp00

–rw-rw-rw- 1 root system 375982 Nov 30 17:25 smit.log.back1

# cp smit.log.back1 smit.log.back2

# ls -l

-rw-rw-rw- 1 root system 375982 Nov 30 17:25 smit.log.back1

-rw-rw-rw- 1 root system 375982 Nov 30 17:28 smit.log.back2

# rm smit.log.back1

# rm smit.log.back2

38

Installation

5. Use the df command to verify that the file systems have successfully automounted after a reboot. Any file systems that were not automounted can be set to automount using the SMIT Change a Journaled File

System screen.

If you are using HACMP or HAGEO, do not set the file systems to automount.

Example

# df

File system 512-blocks free %Used Iused %Iused Mounted on

/dev/hd4 8192 3176 61% 652 31% /

/dev/hd2 1024000 551448 46% 6997 5% /usr

Troubleshooting

If you encounter an error condition, see

“Error conditions” on page 42

for recommended actions.

If you are unable to resolve an error condition, ask your HP support representative for assistance. See

“Calling the HP support center” on page 44 .

41

Error conditions

Error Condition

The logical devices are not recognized by the host.

Recommended Action

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 LUSE devices are not intermixed with normal LUNs on the same port.

Verify that the maximum number of LUSE devices per port has not been exceeded.

Verify that the disk array Host Mode is set correctly.

The host does not reboot properly after hard shutdown.

If you power off the host without executing the shutdown process, wait 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.

Verify that the disk array logical devices are correctly formatted.

Physical volumes cannot be created.

Logical volumes cannot be created.

Verify that the volume capacity for OPEN-x volumes is not greater than the maximum capacity allowed. See the Device Emulations

Appendix.

Verify that the capacity of the volume group is not less than the total capacity of the partitioned logical volume.

42

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Error Condition Recommended Action

A file system is not mounted after rebooting.

Verify that the host was restarted correctly.

Verify that the file system attributes are correct.

The disk array performs a self reboot because the disk array was busy or it logged a panic message.

Reboot the host.

The disk array responds “Not

Ready” or the disk array has displayed “Not Ready” and timed out.

Contact HP.

The host detects a parity error.

Check the HBA and make sure it was installed properly.

Reboot the host.

The host hangs or devices are declared and the host hangs.

Make sure there are no duplicate disk array TIDs and that disk array

TIDs do not conflict with any host TIDs.

Troubleshooting

43

Calling the HP support center

If you need to call HP customer support, provide as much information about the problem as possible, including the circumstances of the error or failure and the exact content of any error messages.

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.

Disk array device emulations

51

52

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 =

Notes for disk parameters

1. The value of pc is calculated as follows: pc = nc

nt

ns

The nc of OPEN-x CVS corresponds to the capacity specified by SVP or remote console.

The CVS size of OPEN-x is specified by capacity (megabyte), not by number of cylinders.

The number of cylinders of an OPEN-x CVS volume can be obtained by the following calculation (

↑ ↑ means round up to integer).

The number of cylinders =

(specified capacity in megabytes from

SVP or remote console)

×

1,024 / 720

↑ .

Example

When 37 MB is specified for an OPEN-3 CVS volume from SVP, the number of cylinders of the OPEN-3 CVS can be calculated as follows:

37

×

1,024 / 720 = 52.62

52.62

= 53

The OPEN-3 CVS volume has 53 cylinders.

2. The value of pa must be equal to or more than 131,072.

3. The number of cylinders of a Logical Unit Size Expansion (LUSE) composed of OPEN-x CVS volumes corresponds to the capacity specified by the SVP or the remote console. CVS size of

OPEN-x is specified by the capacity (megabytes), not by the number of cylinders. The number of cylinders of the OPEN-x CVS volume can be obtained by the following calculation (

↑ ↑

means round up to integer):

The number of cylinders =

(specified capacity in megabytes from

SVP or remote console)

×

1,024 / 720

↑ ×

n where n is the number of concatenated volumes for LUSE.

62

HP StorageWorks Disk Array XP Operating System Configuration Guide: IBM AIX

Example

When 37 MB is specified for the OPEN-3 CVS volume and the four volumes are concatenated, the number of cylinders of the OPEN-3

CVS can be calculated as follows:

37

×

1,024 / 720

↑ ×

4 =

52.62

↑ ×

4 = 53

×

4 = 212

The LUSE for the OPEN-3 CVS volume has 212 cylinders.

Host bus adapter.

Hewlett-Packard Company.

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.

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 OPEN-

3 LDEVs has a size of 4,693 MB.

Logical Unit Size Expansion, a feature which logically combines LDEVs so they appear as a larger LDEV. This allows a LUN to be associated with 2 to 36 LDEVs. LUSE allows applications to access data requiring large amounts of disk space.

Open Fibre Control.

A general term describing any one of the supported OPEN emulation modes (for example, OPEN-L).

Operating system.

Physical address.

“Path” and “LUN” are synonymous. Paths are created by associating a port, a target, and a LUN ID with one or more LDEVs.

A connector on a channel adapter card in the disk array. A port passes data between the disk array and external devices, such as a host server. Ports are named using a port group and port letter, for example, CL1-A.
