4 Software Configuration After you complete the array hardware installation, you can initialize the array and create a PS Series group with the array as the first group member. Alternately, you can add the array to an existing group. When you expand a group, capacity and performance scale automatically with no impact on users. After completing the software configuration, you can allocate storage and start using the iSCSI SAN array. See Storage Allocation on page 23.
PS4210 Installation Guide Prompt Default gateway (optional) RAID policy 4 Software Configuration Description Network address for the device used to connect subnets and forward network traffic beyond the local network. A default gateway is needed only if you want the array network interface to communicate outside the local network (for example, to allow access to volumes from computers outside the local network). The default gateway must be on the same subnet as the array network interface.
PS4210 Installation Guide 4 Software Configuration After you complete the software configuration, the array becomes a member of a group and its disk storage is available for use.
