Emulex Driver and SAN

Emulex Driver and SAN

Post by Nuno Branc » Wed, 02 Jul 2003 23:37:17

I am having a problem with connecting a SAN to a host over a fibre channel.  

I already have one machine up and ronning with the Emulex LightPulse LP8000,
RedHat 7.3 and mounting a disk created on the SAN.

This was easy the first time, i just installed the lpfcdd driver following
instructions and when I did "insmod lpfcdd" the discs were
detected as /dev/sdb and /dev/sdc. When I try this on the new machine it
does not detect any disks but it does leave something in the
logs like:

Jul  1 10:03:09 tvprod kernel: Emulex LightPulse FC SCSI/IP 1.21g
Jul  1 10:03:09 tvprod kernel: PCI: Enabling device 03:04.0 (0116 -> 0117)
Jul  1 10:03:10 tvprod kernel: !lpfc0:1304:LKe:Link Up Event received Data:
x1 x1 x1 x0
Jul  1 10:03:13 tvprod kernel: scsi0 : HBA: Emulex LightPulse LP8000 on PCI
bus 03 device 20 irq 15
Jul  1 10:03:15 tvprod kernel: scsi: unknown type 12
Jul  1 10:03:15 tvprod kernel:   Vendor: DEC       Model: HSG80CCL        
Rev: V85F
Jul  1 10:03:15 tvprod kernel:   Type:   Unknown                          
ANSI SCSI revision: 02
Jul  1 10:03:17 tvprod kernel: scsi: unknown type 12

It says more stuff like this, I suppose this are the hosts in the fibre
switch, unfortunately, no storage device. I was able, however, to work with
2 SDLT tapes that are in the same fibre channel.

Does anyone else had this kind of trouble?

Thanks for the help.

1. Getting IP across a SAN via a Emulex HBA

    I am trying to help a customer get  a AIX TSM server working to
backup up data across a SAN via Emulex LP7000 HBA's using IP.  In other
words, I want to configure a Emulex LP7000 HBA in a AIX 4.3.3 system to
talk IP.  We have installed the latest driver from the FTP site at
Emulex (version, and it doesn't create a FibreChannel IP
adapter device, although it does create one for SCSI.
    I think the rest of the config would be straightforward once we
could get the TCP/IP traffic going across the SAN, and the Emulex card
is the key.
    Has anyone else tried this?

Thanks in advance,

John Schneider
