NOTE: The SAN package may have an updated release of the emlxs /qlc drivers (also known
as the Leadville drivers). See the HP SPOCK website:

Installation Notes for Emulex lpfc Drivers
The following notes apply when connecting to a Solaris host that utilizes an Emulex HBA with an
lpfc driver:
The default or as installed parameter settings will allow the host to connect in either direct
or fabric modes.
Direct Connect
Configured by editing /kernel/drv/lpfc.conf and then running the udated_drv utility. On
versions of Solaris earlier than version 9, you have to manually reboot the host server to update
the host with the modified driver configuration settings.
Fabric Connect
Configured by editing /kernel/drv/lpfc.conf and then running the udated_drv utility. On
versions of Solaris earlier than version 9, you have to manually reboot the Solaris host to update
with the modified driver configuration settings. The sd.conf file is read by the SD driver at boot
time, so supporting entries for new LUNs must exist prior to the last server reboot.
Add entries to the /kernel/drv/sd.conf file between the boundary comments generated by
the Emulex driver package during installation.
# Start lpfc auto-generated configuration -- do NOT alter or delete this line
name="sd" parent="lpfc" target=0 lun=0;
name="sd" parent="lpfc" target=0 lun=1;
...
name="sd" parent="lpfc" target=0 lun=255;
# End lpfc auto-generated configuration -- do NOT alter or delete this line
A line is required for each LUN number (pre 6.20 driver requirement). For fabric configurations,
entries must be made for all target LUNs that will be exported from the HP 3PAR StoreServ Storage
to the Solaris host. These entries can be restricted to the Emulex lpfc driver only, so a useful strategy
is to add entries for all possible LUNs (0 to 255) on target 0. Testing at HP did not reveal any
noticeable increase in server boot time due to the probing of non-existent LUNs.
WARNING! Installing version 6.21g of the lpfc driver for Solaris may be significantly different
than in previous releases. Follow the driver instructions precisely as instructed for initial installation.
Failure to follow the proper installation steps could render your system inoperable.
