Introduction to the Sun Blade Zone Manager

This section covers the following topics:

• Sun Blade Zone Manager Overview
• Supported ILOM Interfaces
• Zoning Configuration Overview
• Supported Hardware and Firmware Configurations

Sun Blade Zone Manager Overview

The Sun Blade Zone Manager handles the SAS-2 storage assignments for the Sun Blade Modular System CPU blades, storage devices, and NEMs. The Zone Manager runs on the chassis monitoring module (CMM) and communicates to the storage resources over Ethernet links between it and the SAS-2 expanders on the storage blades and the NEMs.

Zone Manager allows storage devices from a storage module installed in the chassis to be assigned to a server blade. Storage devices can be assigned to more than one server module (blade) in the case of a cluster.

Currently, Zone Manager is only available for the Sun Blade 6000 Modular System.

Supported ILOM Interfaces

The Sun Blade Zone Manager is available in the Sun Blade 6000 Modular System CMM SW 3.0.10 or later, which includes ILOM 3.0.10 and later.

You can access the Zone Manager through either the ILOM web interface or command-line interface (CLI). The web interface and the CLI are functionally equivalent, but the web interface has some additional ease-of-use features.

This section covers the following topics:

• Accessing Zone Manager Using the Web Interface
• Accessing Zone Manager Using the CLI

Accessing Zone Manager Using the Web Interface

The Sun Blade Zone Manager is accessible through the CMM ILOM Storage tab. It provides two options for setting up the storage configuration:

• Quick Setup enables you to choose from four different zoning configurations to set up the initial zoning.
• Detailed Setup enables you to create or change the zoning configuration by individually selecting blades and storage devices.

The following example shows one of the configurations available through Quick Setup.

See Creating the Chassis Storage Access Configuration Using Quick Setup for more information on Quick Setup.

Detailed Setup enables you to make changes to the zoning configuration that you set up in Quick Setup or to make individual assignments of storage devices to server blades. The following example shows drives being selected for removal from the server blade assignment.

Drives HDD4-HDD7 are selected and highlighted in blue. When the configuration is saved, these storage devices will no longer be associated with the server blade in Slot 1.

For more information on changing a zoning configuration using Detailed Setup, see View and Modify the Chassis Storage Configuration Using the Web Interface.

Accessing Zone Manager Using the CLI

The command-line interface (CLI) provides access to the zoning for blades and storage devices through the /STORAGE/sas_zoning namespace.

When zoning is enabled, blades and NEMs that are SAS-2 capable will be displayed as targets under /STORAGE/sas_zoning. For example:

Storage devices installed on a storage blade are shown as targets of the storage blade. For example, if BL9 is a storage blade installed in Slot 9, the storage devices installed on this blade are shown as follows:

You can access and modify the zoning configurations either through the server blade or the storage blade. Either method has the same result.

Zoning Configuration Overview

The following topics provide an overview of the zoning configurations through the CLI:

• Zoning Commands
• Assigning Storage to a Server Blade
• Assigning a Server Blade to Storage

Zoning Commands

You can assign storage to a server blade or a server blade to a storage device. Either method produces the same result.

When you are assigning storage devices to a server blade, use the following command:

-> set add_storage_access=/CH/BLn/HDDn

Where BLn is the storage blade, HDDn is a hard disk drive installed on the storage blade.

Optionally, you can assign multiple storage devices to a blade in the same command line by separating storage devices with a comma. For example:

-> set add_storage_access=/CH/BLn/HDD0,/CH/BLn/HDD1

When you are assigning a server blade to a storage device, use the following command:

-> set add_host_access=/CH/BLn

Where BLn is the server blade that you are assigning the storage device to.

Assigning Storage to a Server Blade

Before a server blade has a storage device assigned to it, no targets are displayed under the blade. In the following example, BL0 is a server blade in Slot 0.

The following command assigns the HDD0 installed on the storage blade in chassis Slot 9 to the server blade installed in Slot 0.

-> set add_storage_access=/CH/BL9/HDD0

After a storage device is assigned to a server blade, the storage device appears as a target under the server blade. For example:

Assigning a Server Blade to Storage

Before a storage device has a blade assigned to it, no targets are displayed under the storage device. In the following example, HDD0 is a storage device installed on a storage blade installed in Slot 9 of the chassis.

The following command assigns server blade in Slot 0 to HDD0 on storage blade 9:

-> set add_host_access=/CH/BL0

After a server blade is assigned to the storage device, the server blade appears as a target under the storage device. For example:

For detailed instructions on creating and modifying zoning, see the following procedures:

• Creating the Chassis Storage Access Configuration
• Viewing or Modifying the Chassis Storage Access Configuration

Supported Hardware and Firmware Configurations

The following sections describe the hardware and firmware configurations to support the Sun Blade Zone Manager:

• SAS-2 Capable Hardware
• Additional System Requirements

SAS-2 Capable Hardware

All of the following hardware in the chassis must be SAS-2 capable in order to be recognized by the Sun Blade Zone Manager:

• Server blades with SAS-2 REMs
• Network express modules (NEMs)
• Storage blades

If a storage module or server blade is not SAS-2 capable, it is not included in the Zone Manager configuration. The web interface acknowledges the presence of the blade, but it is labeled as a “non SAS-2” device. The blade is not displayed at all in the CLI if it is not SAS-2 enabled.

SAS-2 devices, except for CPU blades, must be powered on to be recognized by the Zone Manager. In addition, SAS-2 devices in a failed state might not be recognized by Zone Manager. Refer to your platform ILOM Supplement documentation or platform Administration Guide for information on detecting component faults.

Additional System Requirements

• Your Sun Blade 6000 Modular System must have a PCIe 2.0 compliant midplane. For more information on determining this, refer to the Sun Blade 6000 Modular System Product Notes.
• Your Sun Blade 6000 Modular System must have software release 3.2.1 installed. This release includes the minimum CMM ILOM firmware version (3.0.10.15a), which supports SAS-2 and includes the Sun Blade Zone Manager.
• You must have already installed your SAS-2 supported components (server module with SAS-2 REM, SAS-2 NEMs, and SAS-2 storage modules).
• Your SAS-2 NEM must be at a firmware version level that supports zoning. Check your NEM Product Notes for version information and available updates.
• You must have already performed initial setup and configuration of your CMM ILOM and planned your connection method (web browser or CLI) as described in Chapter 2 of this document.

Creating the Chassis Storage Access Configuration

There are three options for creating chassis storage access: the web interface using Quick Setup, the web interface using Detailed Setup, and the CLI. You can also use a backup zoned configuration by recovering the configuration as shown in Recovering Zoning Configurations.

Quick Setup is a wizard for automating the process of creating an initial chassis storage access configuration for SAS-2 compliant CPU blades. Quick Setup is only available through the ILOM web interface. There is no Quick Setup equivalent for the CLI.

This section covers the following topics:

• Creating the Chassis Storage Access Configuration Using Quick Setup
• Creating the Chassis Storage Access Configuration Using Detailed Setup
• Creating a Chassis Storage Configuration Using the CLI

Creating the Chassis Storage Access Configuration Using Quick Setup

The Quick Setup option through the ILOM web interface enables you to choose from four different configuration options to zone the blades and storage devices in the chassis.

This section covers the following topics:

• Quick Setup Options
• Use Quick Setup to Create an Initial Chassis Storage Configuration Using the Web Interface

Quick Setup Options

There are four options available for Quick Setup described in the following topics:

• Option 1: Assign per Individual Disks
• Option 2: Assign per Adjacent Individual Disks
• Option 3: Assign per Storage Blade
• Option 4: Assign per Adjacent Storage Blade

Option 1: Assign per Individual Disks

This option uses a round-robin algorithm to assign disks to hosts. Ownership of disks is spread evenly across available storage modules.

This option is best for fault tolerance where the failure or removal of a single storage module will not bring down an array.

Option 2: Assign per Adjacent Individual Disks

This option equally divides the number of storage devices among the server blades. All servers are assigned as close to the same number of disks as possible.

Instead of assigning the storage in a round-robin fashion among all available storage blades, the storage is assigned from storage blades that are adjacent to the server blades. If there are no storage blades adjacent to the server blade, then the nearest possible storage blade is used.

This is a good option to use if you have more server blades than storage blades, and want to have an equal number of storage devices assigned to each storage blade.

Option 3: Assign per Storage Blade

This option looks for servers (starting at Slot 0) and assigns the closest available storage module. If there are seven servers and three storage modules, only the first three servers will be assigned a storage module.

This option is best to use when there are an equal number of storage blades and modules or more storage blades than modules. Otherwise, some server blades will not be assigned to any storage device.

Option 4: Assign per Adjacent Storage Blade

This option looks for servers with storage modules in adjacent slots and one per server. If the server does not have a storage module in an adjacent slot, it is not assigned any storage.

This option works best when there are an equal number of storage blades and server blades, and each server blade has a unique storage blade installed adjacent to it.

Before You Begin: Ensure that your chassis configuration meets the requirements in Supported Hardware and Firmware Configurations.

1. Access the Sun Blade Zone Manager. See Accessing the Sun Blade Zone Manager.

2. In the Sun Blade Zone Manager section, click the Quick Setup button.

A warning message appears.

3. Click OK if you are willing to overwrite any existing zoning.

The Quick Setup screen appears.

Note that any HDD slots that do not have a storage device installed are labeled “empty.” These slots are not included in the Quick Setup configuration.

4. Choose one of the Quick Setup options.

See Quick Setup Options for explanation of each option.

After you make the selection, the screen shows the color-coded zoning assignments between the CPU blades and storage devices (HDDs). Although the Sun Blade Zone Manager assigns the NEM0 and NEM1 External SAS connections, these connections are not officially supported.

5. Click the Save button to save the configuration.

See Saving the Chassis Storage Access Configuration for more information on what happens when you save the configuration.

6. Back up the configuration.

See Backing Up the Storage Access Configuration.

Creating the Chassis Storage Access Configuration Using Detailed Setup

You can use the New Assignments option in Detailed Setup to manually create the chassis storage access configuration.

Before You Begin: Ensure that your chassis configuration meets the requirements in Supported Hardware and Firmware Configurations.

1. Access the Sun Blade Zone Manager.

See Accessing the Sun Blade Zone Manager.

2. In the Sun Blade Zone Manager section, click the Detailed Setup button.

The following message appears if you do not have a chassis storage configuration set up.

3. Do one of the following:

• If you want to continue with the Detailed Setup setup, click Cancel.

Clicking Cancel will open the Detailed Setup page.

• If you want to set up the original configuration in Quick Setup, click OK.

Clicking OK will open the Quick Setup page. See Creating the Chassis Storage Access Configuration Using Quick Setup for more information on Quick Setup.

4. Click the New Assignments button.

5. Click on a server blade and then click on the HDDs to be assigned to the server blade. Alternatively, select more than one server blade for the assignment.

Note that any HDD slots that do not have a storage device installed are labeled “empty.” These slots cannot be assigned to a server blade.

Caution - If you assign an HDD to more than one server blade, ensure that the server blade is enabled for multipathing. For more information see Assign Multiple Server Blades to a Storage Device Using the Web Interface.

Although the Sun Blade Zone Manager can assign them, NEM0 and NEM1 External SAS connections are not supported at this time.

6. Click Save to save the configuration.

See Saving the Chassis Storage Access Configuration for more information on what happens when you save the configuration.

7. Back up the configuration.

See Backing Up the Storage Access Configuration.

Creating a Chassis Storage Configuration Using the CLI

You can create a chassis storage configuration either by assigning storage to a server blade or assigning a server blade to a storage device. Either method provides the same results.

Before You Begin: Ensure that your chassis configuration meets the requirements in Supported Hardware and Firmware Configurations.

1. Access the Sun Blade Zone Manager.

See Accessing the Sun Blade Zone Manager.

2. Use one of the following methods to create a chassis storage configuration:

• Method 1: To assign a storage module device to a server blade, use the following commands:

-> cd /STORAGE/sas_zoning/BLn
-> set add_storage_access=path_to_storage_device

Where BLn is a server blade and path_to_storage_device is the path to the storage device that you want to assign to the blade. For example, /CH/BL1/HDD0.

• Method 2: To assign a server blade to a storage device:

Use the following command:

-> cd /STORAGE/sas_zoning/BLn/HDDn

Followed by:
-> set add_host_access=path_to_blade_server

Where BLn is a storage blade, HDDn is a storage device installed on the storage blade, and path_to_blade_server is the path to the server that you want to assign to the storage device. For example, /CH/BL0.

The following examples show how to use these commands to set up zoning between storage devices on a storage blade in Slot 1 and a server blade in Slot 0.

• Method 1 - Command examples for assigning storage module devices to a server blade:



Command	Description
-> cd /STORAGE/sas_zoning/BL0	Use the cd command to access the host server blade that will be assigned storage.
-> set add_storage_access=/CH/BL1/HDD0	Assign HDD0 of the storage module in blade Slot 1 to the current host.
-> set add_storage_access=/CH/BL1/HDD0,/CH/BL1/HDD1	Assign multiple devices in a single command line. Use the full path to the device and separate each device with a comma (no space).
-> show /STORAGE/sas_zoning/BL0 Targets: 0 (/CH/BL1/HDD0) 1 (/CH/BL1/HDD1)	Use the show command to confirm assigned devices to the current host.



• Method 2 - Command examples for assigning a server blade (BL0) to storage module devices (BL1/HDD0).



Command	Description
-> cd /STORAGE/sas_zoning/BL1/HDD0	Use the cd command to access the storage module device (in this case BL1/HDD0).
-> set add_host_access=/CH/BL0	Assign the current device (HDD0) of the storage module to the host in blade Slot 0.
-> show /STORAGE/sas_zoning/BL1/HDD0 Targets: 0 (/CH/BL0)	Use the show command to confirm assignment of the current device.

3. Back up the configuration.

Saving the Chassis Storage Access Configuration

This section lists important considerations when saving a new or modified storage access zoning configuration and describes the actions that occur when a storage access zoning configuration is saved.

This section covers the following sections:

• Important Considerations About Saving the Zoning Configuration
• Saving a New or Modified Storage Access Configuration

Important Considerations About Saving the Zoning Configuration

When you save a storage access configuration, keep the following in mind:

• The configuration information is saved with the SAS-2 NEMs and storage blades. Changes in zoning hardware configurations can result in loss of the zoning configuration. Back up the configuration immediately after saving it. See Backing Up the Storage Access Configuration.

Refer to the storage blade or NEM documentation for further information on the effect of hot-plugging these components.

• The Zone Manager windows must remain open during the entire Save operation. If the Zone Manager window is closed while the Save operation is in progress, only the portion of the configuration that was processed before the window was closed will be preserved.
• Do not remove or power cycle any of the components included in a zoning assignment while a Save operation is in progress. The zoning configuration will not save properly.

Saving a New or Modified Storage Access Configuration

You can save a new or modified storage access configuration using either the ILOM web interface or the CLI.

• From the web interface: Press the Save button after making the storage access assignments in the Quick Setup or Detailed Setup screens.
