Eclipse™ 2640 SAN Router Administration and Configuration Manual
Configuring R_Ports for mSANs
Table 3-1 R_Port Parameters
Parameter Description
Role The values are Fabric Manager or Non-principal. When a new Fibre
Channel switch is connected and introduced to an existing fabric
through use of the R_Port, an election process is initiated to determine
which switch in the new fabric shall be the
principal switch . To avoid
duplicates, the principal switch is responsible for assigning and
coordinating allocation of Domain IDs to every other switch in the
fabric. The SAN Router will never become the principal switch.
If switch needs to be rebooted, the role displays as “Available after
reset.”
Preferred domain
ID The Preferred Domain ID is the default domain ID for an R_Port on the
SAN Router in question. An Eclipse 2640 SAN Router can have 12
R_Ports, each with its own unique Domain ID. The connected Fibre
Channel switches would considers each R_Port as an individual Fibre
Channel switch. The fabric may assign a different ID if necessary.
This ID is a one-byte hexadecimal field used as part of the Fibre
Channel Port ID address, which is maintained by the mSNS in the
mSAN. The allowed range depends on the Interconnection Mode
setting described below.
• For Brocade mode: 1 to 239. 126 and 127 are reserved.
• For Open Fabric1.0 mode: 1 to 29. 30 and 31 are reserved.
• For McDATA Fabric 1.0 mode: 11 to 29. 30 and 31 are reserved.
Use SANvergence Manager or the CLI to set this parameter. To avoid
potential problems with certain fabric topologies, the following domain
ids are not allowed:
Current domain
ID You cannot set this parameter. The current domain ID is the value that
the domain ID is currently set to. The Current Domain ID is 0 for
R_Ports that are not active.
Status You cannot set this parameter. It indicates the status of this R_Port. For
more detailed information on the Status parameter, refer to the R_Port
status table in the
SANvergence Manager User Manual .
Fabric Manager
Port WWN You can not set this parameter. This is the world wide name (WWN) of
the Fabric Manager R_Port for the FC SAN.
Interconnect
mode Use SANvergence Manager to set this parameter. This is the
interconnection mode to this fabric. Modes are:
• Open Fabric 1.0 - Use for fabrics that are connected to third- party
FC switches that support the FC-SW E_Port implementation.
• McDATA Fabric 1.0 - Use for fabrics that are connected to McDATA
switches that support this McDATA native mode.
• Brocade - Use for fabrics that are connected to Brocade switches.
