Setup Guide

Setting Up a Dell SC5020 and SC5020F Storage System (continued)
To add capacity to an SC5020 storage system, you can connect up to sixteen SC400, eight SC420, or three SC460 expansion enclosures. To add capacity to an SC5020F storage system, you can connect up to eight SC420F expansion enclosures.
A maximum of 222 physical drives are supported in an SC5020 and SC5020F storage system.
NOTE: If the storage system is installed without expansion enclosures, do not interconnect the back-end SAS ports on the storage controllers.
Power on the components of the Storage Center in the
following order:
1. Plug in and power on the network switches, routers, or
other standalone components.
2. Plug in and power on the expansion enclosures that are
connected to the storage system.
NOTE: When powering on expansion enclosures with
spinning hard drives (SC400, SC420, and SC460), wait
approximately three minutes for the drives to spin up
before powering on the storage system.
3. Power on the storage system by pressing the power
switches on both power supply/cooling fan modules to
the ON position.
CAUTION: Do not power off the storage system until
it can be discovered with the Dell Storage Manager
Client. During the initial power up, the storage system
might take up to twenty minutes to boot completely.
The Dell Storage Manager Client provides access to the initial setup wizards. The
wizards help you remotely discover and configure storage systems.
NOTE: The initial setup wizards are only supported on 64-bit
operating systems.
Install and Start the Dell Storage Manager Client
1. Log in to the Dell Digital Locker at www.dell.com/support/software, register your
storage system, and download the Windows or Linux version of the Dell Storage
Manager Client.
2. Install the Dell Storage Manager Client on the host server. To discover and
configure a Storage Center, the software must be installed on a host server that
is located on the same subnet as the storage system. For host setup, the client
does not have to be on the same subnet as the storage system.
3. To start the software on a Windows computer, right-click on the Dell Storage
Manager Client shortcut and select Run as administrator.
To start the software on a Linux computer, execute the command ./Client
from the var/lib/dell/bin directory. The Dell Storage Manager Client
welcome screen opens.
Discover and Configure Storage Center Wizard
1. Click the Discover and Configure Uninitialized Storage Centers link. The
Discover and Configure Storage Center wizard opens.
2. Follow the steps in the wizard to discover and configure Storage Centers.
3. For Fibre Channel installations, the deployment wizard provides the storage
controller WWNs for zoning requirements. When prompted, create the two
required zones for each fault domain.
Configure Fibre Channel Zoning
For Fibre Channel switches, configure zoning to make the Storage Center visible to
the host servers. Using the switch software, create a zone for each HBA connected
to the switch. In the zone, include only one HBA WWN and all of the virtual WWNs
of the storage controller I/O ports connected to that switch. This is referred to as
single initiator/multiple target zoning. For hosts, you can obtain the WWNs from the
operating system or using the switch software.
