composed of disks. This chapter also explains how to

create RAID Group s (and the LUNs on th e RAID

groups).

Chapter 8 Explains how to use the optional Access Logix

feature software that lets you create StorageGroups on an storage system so multiple hosts can

have their own LUNs.

Chapter 9 Introduces the optional EMC MirrorView remote

mirroring feature the ability to maintain a m irrored

copy of current inform ation at a rem ote location. This

chapter also explains how to monitor the remote

mirror, mod ify the remote mirror, and perform oth er

Navisphere Management Environments 1-3


Navisphere Management Environments

Manager runs on a Microsoft Windows NT or Window s 2000 host ,

which is called a management station. It can manage storage systemsconnected to the m anagem ent station or to servers that are accessible

to the man agemen t station over a LAN (local area network). The

storage systems can connect to the servers d irectly, through hu bs, or

through Fibre Channel switches.

Servers with storage systems managed by Manager can run a

Windows operating system, NetWare, or one of several UNIX

operating systems. Servers connected to the same shared storage

system (storage system w ith the Access Logix option) can run

different operating system s. Servers connected to the same u nsha redstorage system (storage system w ithout th e Access Logix option)

must run the same operating system. A server can be connected to

both shared and u nshared storage systems.

Manager communicates with a managed storage system using either

the Host Agent (non-FC4700 series) or the SP Agent (FC4700 series).

For non-FC4700 storage systems, each server w ith a man aged storage

system m ust ru n the Host Agen t. With FC4700 storage systems, the

management station uses a separate network connection to perform

management functions. In addition to the Agent running on the host,

an SP Agent runs in each SP.

The following management environment has a Windows host that is

the man agemen t station for two FC4700 shared stor age systems

connected to servers with Fibre Channel switches. The management

station connects by LAN to the servers. The managemen t station

could also be a storage-system server. It manages the tw o Wind ows

servers and tw o UNIX servers shown .

Configuration Management

Manag er lets you configure the storage systems on local and remote

servers. Using Manager you can

Configure the Host Agents and SP Agents.

Set the configuration, mem ory, and cache p roperties for storage

systems.

Combine p hysical disks into RAID Group s and create logical

un its (LUNs) on those RAID Group s on storage systems with

RAID Group sup port; or combine physical disks into LUNs on

storage systems without RAID Group supp ort.

Mirror a LUN to a remote server using the MirrorView option

to prov ide for disaster recovery.

Change the user-defined parameters of LUNs, such as their

rebuild time and stor age processor (SP) owner.

Upd ate the Core Software and programm able read-only memory

(PROM) code that controls storage system s.

Using Manager on shared storage systems, you can

Set the access control and fair access properties for a storage

system.

Combine LUNs into Storage Group s and connect servers to

Storage Grou ps to p rovide th e servers access to specific LUNs on

the storage system.

Change the user-defined properties of a Storage Group, such as

the LUNs it contains and its nam e.

Copy a LUN at an instant in time using the Snap View option.

Fault and Problem Monitoring 1-7


Fault and Problem Monitoring

Manager lets you monitor faults and problems with storage systems

on local and remote servers. Using Man ager you can

Monitor the statu s of the storage system, ph ysical disks and oth er

compon ents that compr ise it and the Storage Groups, RAID

Groups, and LUNs on the storage system.

Monitor the status of failover softwa re on the stor age-system

servers.

To determine the status of managed storage systems, Manager

period ically polls them and records events. When a storage system is

operating normally, its icon is grey; when it has a failure, its icon isorange; and when it is in a transition state, its icon is blue. You can

expand the Equipment tree or Storage trees for a storage system todisplay its hardware components, managed hosts connected to it, its

RAID Groups, SPs, and Storage Group s, and to show wh ich of these

compon ents failed. Similarly, you can expand the Hosts tree for ahost to display the LUNs, the Storage Group , and the storage systems

connected to it, and to show w hich of these compon ents failed.

Manager Architecture

Manager commun icates with the Host Agent runn ing on the same or

other servers on the network, and also with the SP Agent running in

any FC4700 storage systems. The management station an d the remote

Agents communicate with each other over a TCP/ IP network.

In a shared storage-system environm ent, the Host Agent on a server

commu nicates with ATF or CDE, which in turn comm un icates with

the Base or Core Software runn ing in a storage system s storage

processors (SPs). All shared storag e systems hav e Fibre Chan nel

interfaces to the server, so the Host Agent uses a SCSI protocol over a

Fibre Chan nel (FC) connection to commu nicate with t he Base or Core

Software.

With FC4700 storage systems, the managem ent station u ses a

separate network connection to perform management functions. In

addition to the Agent running on the host, an SP Agent runs in each

SP. The architectural components of a shared stora ge system are

show n in Figure 1-3.

Manager Architecture 1-9


In an unshared storage configuration, the Host Agent on a servercommunicates with the Core Software running in a storage system s

storage processors (SPs), unless the server is running ATF or CDE. If

failover software is running, the Agent communicates with the

software, which in turn communicates with the Core Software.

If an u nsha red storage system has a Fibre Channel server interface,

the H ost Agent uses a SCSI protocol over a Fibre Channel (FC-AL)

connection to commu nicate with the Core Softwa re. If an unshared

storage system has a SCSI server interface, the Host Agent u ses a

SCSI protocol over a SCSI bus to commu nicate with the Core

Softwa re. The architectura l comp onents of an un shared

storage-system configuration are shown in Figure 1-4.

No storage systems with SCSI server interfaces are shared storage systems,

and only certain models of storage systems with Fibre Channel server

interfaces are shared storage systems.

Storage-System Configuration and Management

How you configure or manage storage systems with Manager

dep ends on w hether the storage systems are shared or un shared.

Shared Storage-System Configuration and Management

Before you can configure or man age shared storage systems with

Manager, you need to set up the N avisphere environment.

NOTE: Until you enable data access control for a shared storage system, anyserver conn ected to it can w rite to any LUN on it. To ensure that server s do

not write to LUNs that do n ot belong to them, the procedures below assum e

that either just one server is physically connected to the shared s torage systemor that just one server has been p owered u p since the servers were connectedto the storage system. You w ill use th is server (called the configur ation

server) to configure the storage system.

To Set Up the Navisphere Management Station

1. Install Manager on the managem ent station (Chapter 2).

2. Start Manager and select the configuration server as a host with

storage systems to manage (Chapter 2).

To Install Optional Software on an FC4700 Storage System

Install SnapView or RemoteView software on the FC4700 storage

system (Chap ter 4).

To Set Up the Host or SP Agent

The Agent you set up depends on the storage-system type:

For an FC4700 storage system - Configure the SP Agent on each SP inthe storage system (Chapter 5).

For a storage system other than type FC4700 - Configure the HostAgent on th e server (Chap ter 5).

To Configure a Shared Storage System with Manager

1. Set storage-system general prop erties, mem ory, and cacheprop erties (Chap ter 6).

2. If you w ant fair access to the storage system, set its host

prop erties (Chap ter 6).

6864 5738-001


35/413

1

Storage-System Configuration and Management 1-11


3. Enable da ta access control for the storage system (Chap ter 6).4. Enable configu ration access control for the storage system and

enable configuration access for the configuration server

(Chapter 6).

5. Create RAID Group s and LUN s in the RAID Group s (Chapter 7).

6. Connect other servers to the storage system or pow er up other

servers connected to the storage system.

7. Create Storage Group s and connect each server to its Storage

Group (Chapter 8).

8. Make the LUNs available to the server s operating system . (See

the Navisphere Server Software Administrator s or User Guide

for the server s operating system.)

9. For an FC4700 storage system with the MirrorView remote mirror

option, set up and u se remote mirrors (Chap ter 9).

10. For an FC4700 storage system w ith the SnapView sn apsh ot copy

option, set up the snap shot cache and snap shot (Chapter 10).

After you have configured a ll the storage systems connected to the

configur ation server, you can p hysically connect other servers to the

storage system, or power u p the other servers connected to the

storage system.

To Manage a Shared Storage System with Manager

1. Monitor storage-system operation and the failover softwareopera tion so you can recover from any failures (Chap ter 11).

2. For an FC4700 storage system with the SnapView op tion, if you

want to create snapshots of LUNs, set up and run a snapshot

session (Chapter 10).

3. Reconfigure Storage Group s, LUNs, or RAID Group s, if desired

(Chapter 12).

4. Ad d a server to or remove it from a shared storage system, if

desired (Chap ter 13).

5. Reconfigure storage-system hardw are, if desired (Chapter 13).

Unshared Storage-System Configuration and Management

Before you can configure or manage un shared storage systems with

Manager, you need to set up the Navisphere environment.

6864 5738-001


36/413

1



To Set Up the Navisphere Management Station1. Install Manager on the managem ent station (Chapter 2).

2. Start Manager and select Agents connected to storage systems

you want to manage (Chapter 2).

To Configure an Unshared Storage System with Manager

Manag er cannot configure storage system s without SPs (FC5000

series storage systems), that is, storage systems in a JBOD

(just-a-bunch-of disks) configuration. Man ager can on ly mon itor the

operation of FC5000 series storage systems.

The following procedure assumes that you have:

Physically connected the storage systems you w ant to man age to

their servers

Installed N avisphere CDE or ATF and N avisphere Agent on the

servers

To configu re an unsh ared storage system w ith Manager:

1. Set storage-system general prop erties, mem ory, and cache

prop erties (Chap ter 6).

2. Create RAID Group s and LUN s in the RAID Group s if the storage

system sup ports RAID Groups, or create LUNs if the storage

system does not support RAID Groups (Chapter 7).

3. Make the LUNs available to the server s oper ating system . (Seethe Navisphere Server Software Administrator s or User Guide

for the server s operating system.)

To Manage an Unshared Storage System with Manager

Only step 1 in the procedu re below ap plies to storage systems

without SPs (FC5000 series storage systems).

1. Monitor storage-system operation and the ATF opera tion so you

can recover from any failure (Chapter 11).

2. Reconfigure LUNs or RAID Groups, if desired (Chap ter 12).

3. Reconfigure storage-system hardware, if desired (Chapter 13).

Starting a Manager Session 2-5


Starting a Manager Session

Important: Until you enable data access control for a shared storage system,

any server connected to it can wr ite to any LUN on it. To ensur e that server s

do not w rite to LUNs that d o not belong to them, the procedure in this

section assumes that either just one server is physically connected to theshared storage system or just one server has been powered u p since theservers were connected to the storage system.

You w ill use th is server (called the configuration server) to send the storage

system the configuration command s that you issue from Manager on a

Navisphere management station. The Agent configuration file on each SP

(FC4700 Series) or on th e configurat ion server (FC4500 Series) mu st be set up

to give you configuration access from the management station.

Before you use Manager, the following tasks mu st be comp leted.

Any user can run a Manager session from any management station

on which Manager is installed to mon itor storage systems. How ever,

only an authorized user can use Manager to configure or reconfigure

a storage system. A user is authorized if the Agen t on the SPs

(FC4700 Series) or on the server (non-FC4700 Series) is set up w ith

configur ation access for the user, as described in Chapter 5.

CAUTION!The Agent allows more than one Manager session to access thesame storage system at the same time. As a result, two authorizedusers are able to configure or reconfigure the same storage system

at the same time, but doing this may damage the data.

Task Described in

Install the storage systems and connectthem to the servers directly or through hubsor switches.

Storage-system installation and servicemanual and hub or switch documentation.

Set up the servers whose storage systemsyou want to manage. (Setup includesinstalling CDE or ATF, if using, and installingthe host Agent.)

To Start a ManagerSession Before starting a session, make sure that all storage systems you wantto manage with this session are powered up, and that the Host Agentis runn ing on all servers connected to these storage systems.

1. Log in to the Window s management station as either

Administrator or someone who has administrative privileges.

2. From the Wind ows taskbar, follow the path below to start either

Manager or all installed Navisphere management applications:

ManagerStart Programs Navisphere versionNavisphere Manager

All management applicationsStart Programs Navisphere versionNavisphere Enterprise

3. Click anyw here in the Navisphere Manager splash screen or waitfor the screen to close automatically in 3 seconds.

The Main window opens using the values in the default

app lication configuration file. (For informa tion on the ap plication

configur ation, see th e section Window Configuration on page 3-36).

Manager first looks for the file containing the list of servers

(hosts) that were managed when you closed your last Manager

session. The default file for this list is

drive:\install_directory\Profiles\username\HostAdmin.txt

where drive is the drive and install_directory is the directory wherethe Windows operating system is installed, and username is youruser nam e.)

6864 5738-001

Starting a Manager Session 2-7


If this host file exists, Manager tries to: Extract hostn ames from the file.

Contact each server in the file to determ ine the state of the

storage systems connected to it.

For each storage system it finds, display a storage-system icon

in the Equipment an d Storage trees in each op en EnterpriseStorage dialog box in its Main wind ow.

For each server connected to a storage system tha t it finds,

disp lay a host icon in the Hosts tree in each op en EnterpriseStorage dialog box in its Main wind ow.

If the host file does not exist, the Enterprise Storage dialog boxesremain empty.

If you start Manager while an Agent is starting up, Manager may receive a

time-out error from th at Agent. If such a time-out occurs, Manager d isplays a

dialog box inform ing you of the time-out. Once the Agent is running, you can

either restart Manager or add the server to the list of man aged host s using the

Agent Selection dialog box (page 2-10).

Setting User Options for Manager

Manag er has the following options that you can set to determ ine how

it operates:

Network time out

Sets the time interval in seconds to establish a connection to a

managed storage system and to execute the operation that Manager

requested . If the time interval is exceeded , Manager term inates the

connection.

Host file path

Sets the pa th of the file where the list of hosts with man aged storage

systems is saved between Navisphere sessions.

Save file path

Sets the p ath of the file where the ap plication configuration is saved

between Navisphere sessions.

Polling interval

Sets the time interval in seconds that determ ines how often Manager

perform s a poll operation if autom atic polling for the Manager

session (backgroun d p olling) is enabled, as described next.

Automatic polling

Enables or disables background polling for the session. Backgroun d

polling maintains the polling interval counter and performs poll

operations.

When background polling is enabled, Manager automatically

requests an Agent to poll a managed storage system for updated

information only ifautomatic polling for the storage system isenabled.

If autom atic polling is enabled for a storage system, the polling

interval and the au tomatic polling priority for a storage system

determine how often Manager requests Agents to poll storage

systems. If autom atic polling is not en abled for a storage system

when a poll operation occurs, the information in the Manager s

image of the storage system remains unchanged.

When background p olling is disabled, no poll operations occur.
