6.1A example LUN configuration

This section summarizes how to change the system memory configuration from the default factory configuration to a new configuration, which consists of four partitions and has access lists that allow only four host machines to use the RamSan.

This demonstration assumes the four HBAs and the RamSan’s Fibre Channel ports are attached to the same fabric. In addition, this system has 16 Gigabytes of memory.

The new configuration consists of four partitions that HBAs access using four Fibre Channel ports in the RamSan. This demonstration assigns each HBA a unique LUN. The example results in the following configuration:

6

To change from the default configuration to the one described above, perform the following steps:

Delete the default LUNs (see Section 6.8 )

Add two 6-Gigabyte LUNs (see Section 6.2 )

Add two 2-Gigabyte LUNs (see Section 6.2 )

Link each LUN to an Fibre Channel port (see Section 6.4 )

Add access lists (see Section 6.7 )

Set a backup mode for each LUN in a RamSan-320 (see Section 6.9 )
