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 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:
Figure 6-2: Reconfigured LUN Mapping
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-325 (see Section 6.9 )
