XP Disk Array Configuration Guide for Novell Netware 9

About this guide10

1 Installing and configuring Novell Netware for the XP disk array

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.

Features and requirements

Ask your HP service representative about the latest supported hardware and software.

The disk array has the following features:

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

XP10000: Up to 240 drives for up to 69.2 TB, 48 FC ports XP12000: Up to 1152 drives for up to 332 TB, 128 FC ports XP20000: Up to 240 drives for up to 69.2 TB, 48 FC ports XP24000: Up to 1152 drives for up to 332 TB, 256 FC ports

• Server support: Novell NetWare server

• Operating system support: Check with your HP representative for the current OS versions supported

by your XP disk array.

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

• Fibre Channel Adapter (FCAs): Install FCAs and all utilities and drivers. Refer to the adapter

documentation for installation details.

• (Recommended) HP StorageWorks XP Remote Web Console, HP StorageWorks XP Command

View Advanced Edition Software or HP StorageWorks XP Command View with LUN management feature for configuring disk array ports and paths.

• (Recommended) HP StorageWorks XP Array Manger.

• (Optional) Check with your HP representative for other XP software available for your system.

Fibre Channel interface

The XP family of disk arrays supports these Fibre Channel elements:

• Connection speeds of 1 Gbps, 2 Gbps, and 4 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 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.

XP Disk Array Configuration Guide for Novell Netware 11

Device emulation types

The XP family of disk arrays supports these 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 based on a CVS device. 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-x 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 determine. OPEN-L does not support CVS. Although OPEN-V is a CVS-based device, the product name in the SCSI inquiry string is OPEN-V opposed to the fixed size OPEN-[389E] devices that appear as OPEN-x-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. OPEN-V devices are designated as OPEN-V*n (without CVS).

NOTE:

For the XP24000/XP20000/XP12000/XP10000 when connected to external storage devices, HP recommends using OPEN-V as the emulation the array makes visible to the host. This allows configuration of external storage LDEVs without losing data. Using any other emulation may cause data loss in the external storage LUNs. For new deployments, OPEN-V should be chosen because some features (such as XP Snapshot or Continuous Access Journal) are only supported with OPEN-V.

Refer to Table 6 on page 35 for detailed information.

Failover

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

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 XP Remote Web Console, or XP Command View . For procedures, refer to the applicable user guide available at:

http://www.hp.com/support/manuals.

• Loading the microcode updates

• Installing and formatting devices

After these tasks are finished, use XP Remote Web Console, XP Command View, XP Command View Advanced Edition Software, or XP Array Manager to complete the remaining tasks listed below. If you do not have these programs, your HP service representative can perform these tasks for you.

XP Disk Array Configuration Guide for Novell Netware 13

Setting the host mode and host group mode for the disk array ports

After the disk array is installed, you must set the host mode for each disk array port to match the host OS. Set the host mode using LUN Manager in XP Remote Web Console (shown), XP Command View, or XP Command View Advanced Edition Software. If these are not available, the HP service representative can set the host mode using the SVP. The host mode setting for Novell Netware is 0A.

CAUTION:

The correct host mode must be set for all new installations (newly connected ports) to Novell Netware hosts. Do not select a mode other than 0A for Novell Netware. The host modes must be set for certain middleware environments (for example, Novell High Availability Server, NHAS, System Fault Tolerance, SFT III). Changing a host mode after the host has been connected is disruptive and requires the server to be rebooted.

When a new host group is added, additional host group modes (host mode options) may be configured. The storage administrator must verify if an additional host group mode is required for the host group.

Installing and configuring Novell Netware for the XP disk array14

CAUTION:

Changing host group modes for ports where servers are already installed and configured is disruptive and requires the server to be rebooted.

Setting the System Option Modes

The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Notify your HP representative if you install storage agnostic software (such as backup or cluster software) that may require specific settings.

Configuring the Fibre Channel ports

Configure the disk array Fibre Channel ports by using XP Remote Web Console (shown), XP Command View, or XP Command View Advanced Edition Software. 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. For specific values, refer to the HP StorageWorks XP LUN Manager User's Guide applicable to your array.

Fabric and connection parameter settings

When configuring the disk array, use LUN Manager in XP Remote Web Console, XP Command View, or XP Command View Advanced Edition Software to specify whether the hosts and the disk array are

XP Disk Array Configuration Guide for Novell Netware 15

connected by a fabric switch. Also, you must specify FC-AL or point-to-point in the “Mode” field of the Change Port Mode pane. The default is FC-AL.

If you are using a fabric switch, consult the switch's documentation to determine whether FC-AL or point-to-point should be used. Some fabric switches require that you specify point-to-point to get the system running.

For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide at:

http://www.hp.com/go/sandesign.

Figure 2 Arbitrated loop fabric topology example

Table 2 Fabric topology settings

Installing and configuring the host

This section explains how to install and configure Fibre Channel adapters (FCAs) that connect the host to the disk array.

Loading the operating system 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 FCA manufacturer.

Installing and configuring the FCAs

Install and configure the Fibre Channel adapters using the FCA manufacturer's instructions.

Configuring NetWare Client

NetWare 6.x

Installing and configuring Novell Netware for the XP disk array16

NetWare Client software is required for the client system. After installing the software on the NetWare server, follow these steps:

1. Open the Novell Client Configuration dialog and click the Advanced Settings tab.

2. Change the following parameters:

Give up on Requests to Sas: 180

Net Status Busy Timeout: 90

Configuring NetWare ConsoleOne

NetWare 6.x

Novell NetWare v6.x requires a tool called ConsoleOne to work in a storage environment. ConsoleOne is a free Java utility used to manage network resources. Configure ConsoleOne as follows:

1. Ensure NetWare Client software is already installed.

2. Install ConsoleOne on the NetWare 6.x server.

3. From the NetWare Client, run ConsoleOne:

z:public/mgmt/consoleOne/1.2/bin/ConsoleOne

4. Right click the Server icon, and select Disk Management Devices.

5. Scroll left to the Media tab.

6. Click Partitions, New, and select a device.

7. Click Create, click NSS pools, click New, and name the pool. The pool name and volume name

can be the same.

8. Click Create, click NSS Logical Volume, select New, name the volume, then select the pool.

9. Select Allow volume quota to grow to pool size.

10. Leave the default settings on the next page and click Finish.

Fabric zoning and LUN security

If you plan to use clustering, install and configure the clustering software on the servers.

Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes. The nodes share access to the disk array.

XP Disk Array Configuration Guide for Novell Netware 17

Figure 3 Multi-cluster environment

Within the Storage Area Network (SAN), the clusters must be homogeneous (all the same operating system). Heterogeneous (mixed operating systems) clusters are not allowed. How you configure LUN security and fabric zoning depends on the SAN configuration.

Fabric zoning and LUN security for multiple operating systems

You can connect multiple clusters with multiple operating systems to the same switch and fabric using appropriate zoning and LUN security. Note:

• 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 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.

Connecting the disk array to the NetWare server

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

1. Verifying operational status of the disk array channel 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 XP Remote Web Console (shown), XP Command View (XP arrays only), or XP Command View Advanced Edition Software to define paths (LUNs) between hosts and volumes in the disk array.

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

• Configuring ports

• Enabling LUN security on the ports

• Creating host groups

• Assigning Fibre Channel adapter WWNs to host groups

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

In XP Command View Advanced Edition Software, LUN mapping includes:

• Configuring ports

• Creating storage groups

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

For details see HP StorageWorks XP LUN Manager User's Guide or HP StorageWorks XP Command View Advanced Edition Software Device Manager Web Client User's Guide. Note the LUNs and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.

Verifying new device recognition

To verify that the NetWare system recognizes the new disk array devices:

1. In the NetWare directory, enter SERVER to get to the server console.

2. At the server console, enter LIST DEVICES to display all devices. Use the Pause key as needed.

The device number (for example, 0x000B) and device type are displayed for each device:

Example

XP Disk Array Configuration Guide for Novell Netware 19

NetWare prompt> LIST DEVICES

1. 0x000B: [V6E0-A2-D7D:0] HP OPEN-3 rev:0111

2. 0x000C: [V6E0-A2-D7D:1] HP OPEN-3 rev:0111 : :

3. Record the device number for each new device on the worksheet in “Path Worksheet” on page 33.

This information will be useful later during disk partitioning and volume creation.

4. Verify that all new disk devices are listed.

Configuring disk devices

Configure the disks in the disk array using the same procedure for configuring any new disk on the host. This includes the following procedures:

1. Creating the disk partitions

2. Assigning the new devices to volumes

3. Mounting the new volumes

4. Verifying client operations

Creating scripts to configure all devices at once may save you considerable time.

Creating the disk partitions

Before you create the disk partitions, consult the Novell documentation for confirmation about the type of partition that is available with your operating system version.

Installing and configuring Novell Netware for the XP disk array24

2 Middleware configuration

The disk array supports many industry-standard middleware products which provide host failover and logical volume management. Available host failover products for the Novell NetWare server operating system include the Novell High Availability Server (NHAS), SFT III software products, Novell Clustering Services, and Novell Multipath Support.

Logical volume management functions are included in the Novell NetWare server operating system (for example, Installation Option NetWare Loadable Module, NWAdmin).

Host failover

The NHAS and SFT III software products provide hardware fault tolerance (that is, host failover capability) for the Novell NetWare environment.

Novell Clustering Service provides fault tolerance by moving (failing over) server resources from one server to another.

If you plan to use these products with the disk array, contact your HP service representative for the latest information about support and configuration requirements.

For assistance with NHAS or SFT III operations, see the Novell user documentation, or contact Novell customer support.

Multipath failover

The XP disk arrays support NetWare multipath failover. If multiple FCAs are connected to the disk array with commonly-shared LUNs, you can configure path failover to recognize each new device path:

1. In the startup.cfg file, enter

SET MULTI-PATH SUPPORT=ON LOAD SCSIHD.CDM AEN

2. If the line LOAD CPQSHD.CDM is present it should be commented out.

Example startup.cfg

SET MULTI-PATH SUPPORT=ON LOAD ACPIDRV.PSM ######## End PSM Drivers ######## LOAD SCSIHD.CDM AEN #LOAD CPQSHD.CDM LOAD IDECD.CDM ######## End CDM Drivers ######## LOAD IDEATA.HAM SLOT=10011 LOAD CPQRAID.HAM SLOT=10019 LOAD QL2300.HAM SLOT=2 /LUNS /ALLPATHS /PORTNAMES/CONSOLE LOAD QL2300.HAM SLOT=3 /LUNS /ALLPATHS /PORTNAMES /CONSOLE ######## End HAM Drivers ########

XP Disk Array Configuration Guide for Novell Netware 25

3. Restart the server.

4. To see a list of the failover devices and paths, at the server prompt enter:

list failover devices

Example failover device path listing

Helpful Multipath commands

Other useful Multipath commands are described below.

MM Set failover priority <pathid> = <number> </insert>

This command sets the priority level for each path. The ID must be a valid path ID, and the number must be a decimal integer value in the range 1-4,000,000, with 1 being the highest priority and 4,000,000 being the lowest priority. The default value of 0 (zero) indicates that there is no priority.

The /insert option will move the priorities on all paths that were equal or lower than <number>. For example, if the paths had priorities of 1,2,3,4, and a new path is assigned a number 2 using the /insert option, then the paths that were 2, 3, and 4 are moved to 3, 4, and 5, and the new path assigned priority 2.

MM Set failover state <pathid> = <Up: Down> </setpath>

This command sets the state of the path. The ID must be a valid path ID. If the path is Up, it can be taken offline, and will not be used to switch to. Another path will be selected. If the path is offline, the path will be reactivated, if possible, and set to an Up state. The /setpath option will reselect the highest priority path that is up.

MM Set failover path <pathid>

This command moves the selected path to the one specified by the path ID. The ID must be a valid path that is up. This does not alter the priorities on the paths, and any reselection of the path may cause the path to change. A later option will be added to reassign that path to the highest priority.

MM Restore failover path device_id

This command forces the device to reselect the highest priority path that is online. The device_id must be a valid device ID.

Middleware configuration26

MM Reset failover registry

This command will delete all the failover entries in the registry, and recreate them again based on the current set of failover devices.

As a path fails, it is automatically marked as a Down (offline) path, and the next highest priority path is automatically selected. When the device is reactivated, the state is automatically reset to an Up (online) state, and again the highest priority path is selected.
