Special considerations
1. If clustering, then one node is chosen as the primary node . It is used to
configure both nodes in the cluster. If using remote mirroring, there is a primary
node at each site. A single node gateway is its own primary node. It is this
primary node’s IP address that is used first (for accepting the software license
agreement and “Installing the Web-based System Manager Remote Client” on
page 15). When remote mirroring, the remote site’s primary node is used first.
After Step 1 of initial configuration completes on the remote site primary node,
then you must log on to the local site primary node to complete Step 2 of initial
configuration for the entire geographic cluster.
2. You must configure your external storage on the devices before you can create
volumes on the NAS Gateway 500. You do this through standalone clients,
using the software provided by the storage manufacturer. If you need the World
Wide Port Name (WWPN) for the fibre channel host bus adapters installed in
your NAS Gateway 500, open a Web browser and enter:
http:// HostAddress /NAS500GetWWN.html
where HostAddress is the host name or IP address that is assigned to the NAS
Gateway 500 (or, in the case of a cluster, a specific node).
The NAS Gateway 500 is capable of attaching to multiple types of disk storage
devices and uses different device drivers depending on the device to which it is
attached. If you are using a device that requires the usage of the Subsystem
Device Driver (SDD) in a clustered environment, the process of configuring a
NAS volume is slightly altered. The driver must be installed before you define
any NAS volumes.
Caution: Do not perform any NAS volume configuration before installing the
SDD. You will lose your volume configuration information if you install
the SDD afterwards.
See Chapter 13, “Using the Volume Wizard,” on page 59 for information about
the SDD and how it changes NAS volume configuration.
Accepting the license agreement
You must accept the license agreement to begin the initial configuration process.
You are not able to access the WebSM Remote Client to configure the NAS
Gateway 500 until you have accepted the license agreement.
To accept the NAS Gateway 500 System Software license agreement:
1. From Windows or Linux, open a frames-capable Web browser. Enter the IP
address from the LCD panel on the front of the NAS Gateway 500.
2. A Web page for language selection is displayed. Make your language selection
and click Continue . This sets the default language that is used on the NAS
Gateway 500.
3. A Web page for the license agreement for the NAS Gateway 500 System
Software is displayed. Read the license agreement and click Accept .
4. Select a different language on the license acceptance page, if desired. This
changes the language used to display the license text. It does not change the
default language for the NAS Gateway 500.
5. After you accept the license agreement, the default html page (index.html) on
the NAS 500 Gateway is renamed to NAS500Index.html, leaving no default
page. Subsequent access to the default page results in a file listing being
