About This Guide

Dell™ PowerVault™ Modular Disk (MD) Storage Manager software is used to create and manage multiple storage arrays. The software can be used on any host attached to the storage array, as well as on storage management stations connected to the same sub-network.

MD Storage Manager is a graphical user interface (GUI) with wizard-guided tools and a task-based structure designed to reduce the complexity of installation, configuration, management, and diagnostic tasks.

MD Storage Manager software also contains an optional event monitoring service that is used to send alerts when a critical problem with the storage array occurs and a command line interface (CLI) to access functions performed by MD Storage Manager.

This guide is intended for users who are already familiar with the basic functions of their storage array. Any differences in certain functions between supported operating systems are explained where applicable.

MD Storage Manager online help contains detailed answers to softwarerelated questions. You can access online help by clicking Help located at the top right corner of the MD Storage Manager interface. Refer to your storage array’s

About Your Storage Array

This chapter covers basic information about how to manage storage arrays from MD Storage Manager, including adding and removing arrays from the software, performing initial setup tasks, setting passwords on an array, and configuring alert notifications. For information on planning your storage array, see the Installation Guide.

Following is a list of terms that are used throughout this chapter:

• Physical Disk — Non-volatile, randomly-addressable device for storing data.

• Host —

disks.

• Host Group — Hosts that are logically associated and share access to the same virtual disks.

• Host-Agent Software — Software installed on the host that provides inband management and topology discovery.

• Logical Unit Number (LUN) — Address that identifies individual virtual disks within a storage array.

• Event Monitor — A

managed storage arrays and notifies a host or remote system when critical problems occur.

• SNMP Alert — Alert (SNMP trap) that is sent from the event monitor to an SNMP-enabled host.

System that accesses a storage array and is mapped to virtual

feature that, when enabled, monitors activity on

Access Virtual Disk

Each RAID controller in an MD Storage Array maintains an access virtual disk. The host-agent software uses the access virtual disk to communicate

management requests and event information between the storage management station and the RAID controller module in an storage array. The access virtual disk is not available for application data storage. The default LUN is 31.

in-band–managed

Storage Array 15

NOTICE: Removing or manipulating an access virtual disk can cause a loss of

management access. If you remove an access virtual disk mapping from an in-band-managed storage array, MD Storage Manager can no longer access the storage array. Do not modify the access virtual disk either in the operating system or with MD Storage Manager.

Out-of-Band and In-Band Management

You can manage a storage array in two ways:

• Out-of-band management

• In-band management

For out-of-band management, data is separate from commands and events. Data travels through the host-to-controller interface, while commands and events travel through the management port Ethernet cables.

When you use out-of-band management, you must set the network configuration for each RAID controller module’s management Ethernet port, including its Internet Protocol (IP) address, subnetwork mask (subnet mask), and gateway. If you are using a Dynamic Host Configuration Protocol (DHCP) server, you can enable automatic network configuration, but if you are not using a DHCP server, you must enter the network configuration manually.

NOTE: RAID controller module network configurations can be assigned using a

DHCP server (the default setting). However, if a DHCP server is not available and the 10-second selection period times out, the RAID controller modules use the

192.168.128.101 static IP address for controller 0. For controller 1, the RAID controller modules use the 192.168.128.102 static IP address.

For in-band management, commands, events, and data travel through the host-to-controller interface. Unlike out-of-band management, commands and events are mixed with data.

For detailed information on setting up in-band and out-of-band management see the Installation Guide.

NOTE: In-band management is not supported on systems running the Red Hat®

Enterprise Linux

3 operating system.

16 Storage Array

Adding Storage Arrays

To add a storage array to MD Storage Manager, click New in the Array Selector area. A window is displayed that allows you to choose the automatic or manual process to add a new storage array.

NOTE: Verify that your host or management station network configuration—

including station IP address, subnet mask, and default gateway—is correct before adding a new storage array using the Automatic option.

NOTE: For Linux, set the default gateway so that broadcast packets are sent to

255.255.255.255. For Red Hat default gateway to the IP address of the NIC.

NOTE: MD Storage Manager uses TCP/UDP port 2463 for communication to the

MD Storage Array.

Automatic Discovery of Storage Arrays

The Automatic Discovery process sends out a broadcast message across the local subnetwork (subnet) and adds any storage array that responds to the message. The Automatic Discovery process finds both in-band and out-ofband storage arrays.

Manual Addition of a Storage Array

Use Manual Addition if the storage array resides outside of the local subnet. This process requires specific identification information to manually add a storage array:

• To add a storage array that uses in-band management, specify the host name or IP address of the host.

When adding a storage array using in-band management with iSCSI, a session must first be established between the initiator on the host server and the storage array. For more information, see "Configuring iSCSI" in the

Modular Disk 3000i Systems Installation Guide.

Linux®, if no gateway exists on the network, set the

The host agent must be restarted before in-band management communication can be established. See "Starting or Restarting the HostAgent Software in Windows" on page 28 or "Starting or Restarting the Host-Agent Software in Linux" on page 28.

Storage Array 17

• To add a storage array that uses out-of-band management, specify the host name or IP address of each controller in the storage array.

NOTE: It can take several minutes for MD Storage Manager to connect to the

specified storage array.

Naming Storage Arrays

Each storage array should be assigned a unique name. A storage array name has a 30-character limit. All leading and trailing spaces are deleted from the name. A name can consist of letters, numbers, and the special characters underscore (_), dash (–), and pound sign (#). No other special characters are allowed.

NOTE: Avoid arbitrary names or names that might lose meaning in the future.

Removing Storage Arrays

You can remove a storage array from the list of managed arrays if you no longer want to manage it from a specific storage management station. Removing a storage array does not affect the storage array or its data in any way. Removing a storage array simply removes it from the list of storage arrays that appear in the drop-down list in the Array Selector. If a storage array is accidentally removed, it can be added again (see "Adding Storage Arrays" on page 17).

Password Guidelines

Consider these guidelines when you create a password:

• Use secure passwords for your storage array. A password should be easy for you to remember but difficult for others to determine. Consider using numbers or special characters in the place of letters, such as a 1 in the place of the letter

• For increased protection, use a long password with at least 15 alphanumeric characters. The maximum password length is 30 characters.

• Passwords are case sensitive.

• For security reasons, you can attempt to enter a password only ten times before the storage array enters a lockout state. Before you can try to enter a password again, you must wait ten minutes for the storage array to reset.

or the at sign (@) in the place of the letter a.

Resetting a Password

Perform this procedure when you have lost or forgotten your password and you need to reset it.

Connecting the Serial Cable

Changing Expansion Enclosure ID Numbers

When an MD1000 expansion enclosure is attached to an MD3000/MD3000i storage array for the first time, an enclosure ID number is assigned and maintained by the MD1000. This enclosure ID number is also shown in the MD Storage Manager, but it is not an indicator of the enclosure’s physical location. It may appear that MD Storage Manager is reporting the expansion enclosures in improper order.

You can change the enclosure ID numbers in the MD Storage Manager by clicking the To ol s menu and then clicking Change Enclosures ID Numbers. Any ID number you assign will not conflict with the enclosure IDs.

Configuring Alert Notifications

MD Storage Manager can send an alert for any condition on the storage array that requires your attention, such as the failure of a storage array component or the occurrence of an adverse environmental condition. Alerts can be sent as e-mail messages or as SNMP messages.

You can verify whether alerts are currently set by looking at the Alert status line in the Status area of the Summary tab.

Configuring E-mail Alerts

To configure e-mail alerts, click the Tools tab and then click Set up e-mail alerts. The Content Area displays two links: Configure Sender E-mail Settings and Add or Edit E-mail Addresses.

NOTE: These settings apply to all storage arrays currently managed by the

management station.
