World Wide Name

[Sandra R.]

How do you find on Hp server? Thanks

[Michael Tully]

# ioscan -fnkC | grep td
Use the /dev/td0 etc to get the in put for this.
# /opt/fcms/bin/fcmsutil /dev/td?

[Dave Hutton]

On the new servers we just got in had it printed on a sticker on the card itself. You can see it without cracking the case of your server though. Otherwise:
#fcmsutil /dev/td0


Vendor ID is = 0x00103c
Device ID is = 0x001029
XL2 Chip Revision No is = 2.3

N_Port Node World Wide Name = 0x50060b00001e74cf
N_Port Port World Wide Name = 0x50060b00001e74ce
Driver state = ONLINE
Hardware Path is = 0/0/10/0/0

Hi Sandra,

To detrmine the WWN of your fibre channel adapters do the following:

1) ioscan -fnC
Look under the "I" column for instance number. Then this will be combined with the driver "td" for the next command

2) fcmsutil /dev/tdX
Where X=td instance. The output of this will give you the WWN in the "N_Port Node World Wide Name = " line.

HTH,
Jeff

Hi Sandra,

To detrmine the WWN of your fibre channel adapters do the following:

1) ioscan -fnC fc
Look under the "I" column for instance number. Then this will be combined with the driver "td" for the next command

2) fcmsutil /dev/tdX
Where X=td instance. The output of this will give you the WWN in the "N_Port Node World Wide Name = " line.

HTH,
Jeff

fcmsutil would show you this.

/opt/fcms/bin/fcmsutil /dev/devname should give you the world-wide name

-USA..

[Jeff Schussele]

Sorry for the double posts. I left the "fc" out of the ioscan command in the first.

Dumb of me not to mention, but if your contemplating zoning, the number your after is the port world wide name.

Vendor ID is = 0x00103c
Device ID is = 0x001028
TL Chip Revision No is = 2.3
PCI Sub-system Vendor ID is = 0x00103c
PCI Sub-system ID is = 0x000006
Topology = PTTOPT_FABRIC
Local N_Port_id is = 0x021900
N_Port Node World Wide Name = 0x50060b000007b455
N_Port Port World Wide Name = 0x50060b000007b454
Driver state = ONLINE
Hardware Path is = 0/0/6/0/0
Number of Assisted IOs = 13025470
Number of Active Login Sessions = 1

fcmsutil Will output the WWN

/opt/fcms/bin/fcmsutil /dev/[device file driver]


-- you can find the device driver with:

/usr/sbin/ioscan -fnC lan or

/usr/sbin/ioscan -fnC fc (fibre)

[Sandra R.]

Thanks a bunch guys!

Hi,

The device name is really dependent on what cards you have. For tachyon type cards, it is /dev/td*, for simple fiber channel mass storage it is
/dev/fcms*

So you do a "ll /dev/td* /dev/fc*' to find out the devices and then run fcmsutil or tdutil on them.
