Enabling persistent binding

Connecting to the Storage

3. Set the lpfc_scan_down parameter as follows:

The default setting is:

lpfc_scan_down=1

Change it to zero:

lpfc_scan_down=0

4. Set the lpfc_automap parameter as follows:

The default setting is:

lpfc_automap=1

Change it to zero:

lpfc_automap=0

5. Set the lpfc_fcp_bind_WWPN parameter to the required number

of persistent binding entries.

Example:

lpfc_fcp_bind_WWPN=50060160006000ed:lpfc0t1,500601680

06000ed:lpfc0t2,50060160006000ed:lpfc1t1,500601680060

00ed:lpfc1t2

Note: The entry must be all on one line; the length of the line forces it to

wrap to multiples lines in this document.

6. Save the changes to /etc/modules.conf.

The following is an example of

/etc/modules.conf for a v2.4.x

system using the Emulex driver with persistent binding enabled:

alias parport_lowlevel parport_pc

alias scsi_hostadapter sym53c8xx

alias scsi_hostadapter1 lpfc

alias scsi_hostadapter2 lpfc

alias eth0 tlan

options scsi_mod max_scsi_luns=255 scsi_allow_ghost_devices=1

options lpfc lpfc_topology=0x02 lpfc_automap=0 lpfc_scan_down=0

lpfc_fcp_bind_WWPN=50060160006000ed:lpfc0t1,50060168006000ed:lpfc0t2,50060160060

00ed:lpfc1t1,50060168006000ed:lpfc1t2

Note: The last three lines of the example are actually all one line; however,

the length of the line forces it to wrap to multiples lines in the display.
