EMC Host Connectivity with Emulex FC HBAs and FCoE CNAs for the Linux Environment

Editing /usr/src/lpfc/lpfc.conf
The Emulex v7.1.14 driver uses the lpfc_fcp_bind_method
parameter. When using the lpfc_fcp_bind_method parameter, the
following values will force a particular type of binding:
A value of 1 forces WWNN binding.
A value of 2 forces WWPN binding.
A value of 3 forces DID binding.
A value of 4 forces the driver to derive the binding from ALPA.
EMC recommends enabling persistent binding via WWPN; therefore,
the default value of 2 should be used.
To edit
/usr/src/lpfc/lpfc.conf and compile the persistent
binding parameters into the driver, follow these steps:
1. Please note the following requirements when enabling persistent
binding:
Only one persistent binding method can be used.
•The
lpfc_automap parameter must be set to 0.
•The
lpfc_scan_down parameter must be set to 0.
2. As stated previously, the
lpfc_scan_down parameter must be set
to 0 when using persistent binding. Search for the
lpfc_scan_down parameter in /usr/src/lpfc/lpfc.conf and
change the value from:
int lpfc_scan_down = 1;
to
int lpfc_scan_down = 0;
3. Next, the lpfc_automap parameter must be set to 0 when using
persistent binding. Search for the
lpfc_automap parameter in
/usr/src/lpfc/lpfc.conf and change the value from:
int lpfc_automap = 1;
to
int lpfc_automap = 0;
