Gateway System Installation
A Data Domain Gateway system that uses external storage must first connect with the external
storage. After connecting, it needs to be configured in order to use this storage.
Multiple storage array RAID configurations can be used; however, you should select RAID
configurations that provide the fastest possible sequential data access for the type of disks used.
When using a SAN-attached Data Domain Gateway system, the SAN must be zoned before the
Data Domain system is booted.
To install a gateway system:
1.
Physically install the Data Domain Gateway system. For a DD580g, see “Installation” on
page 57. For a DD560g or DD460g, see “Installation” on page 71.
2.
On the external disk array system, create the logical units (LUNs) for use by the Data Domain
system.
3.
On the external disk array system, configure LUN masking so that the Data Domain system
can see only those LUNs that should be available to the Data Domain system. The Data
Domain system writes to every LUN that is available.
4.
Connect the Fibre Channel cable from one Fibre Channel controller port on the disk array to
one of the Fibre Channel HBA card ports on the back of the Data Domain system (use only one
port on the HBA card).
5.
Connect a serial terminal to the Data Domain system. A VGA console does not display the
menu mentioned in the next step of this procedure.
6.
Press the
Power
button on the front of the Data Domain system. During the initial system start,
the Data Domain system does not know of the available LUNs. The following menu appears
with the
Do a New Install
entry selected:
New Install
1. Do a New Install
2. Show Configuration
3. Reboot
7.
Check that the LUNs available from the connected array system are correct. Use the
down-arrow key, select
Show Configuration
, and press
Enter
. The configuration menu appears
with
