6.1
A 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 two partitions and has access lists that allow only two host
machines to use the RamSan.
This demonstration assumes the two HBAs and the RamSan’s Fibre
Channel ports are attached to the same fabric. In addition, this system
has 8 Gigabytes of memory.
The new configuration consists of two partitions that HBAs access using
two Fibre Channel ports in the RamSan. This demonstration assigns each
HBA a unique LUN. The example results in the following configuration:

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

LUN 1
Port 1B

•
Delete the default LUNs (see Section 6.8 )
•
Add one 6-Gigabyte LUN (see Section 6.2 )
•
Add one 2-Gigabyte LUN (see Section 6.2 )
•
Link each LUN to a Fibre Channel port (see Section 6.3 )
•
Add access lists (see Section 6.7 )
•
Set a backup mode for each LUN in a RamSan-120 (see Section 6.9 )
