Shalom,

ioscan output will tell you how many HBA cards you have.

You also get the device names which you can input into fcmsutil for more information

ex: fcmsutil /dev/td0

Hi,

It depends upon the model of your server and what it can support.

Post the output from the 'model' command, i.e. :

/home/markme# model
ia64 hp superdome server SD32B

The following commands will show how many HBA Cards the system currently has configured :

/home/markme# ioscan -funNC fc

Maybe one, maybe 30. Since there are dozens of models of HP computers that will run 11.31, there is no way to tell how many you can add to your server. If you mean: how many HBAs are actually installed, use ioscan aas mentioned above.

>i want to know how many we have in our SAN Sotrage

There is no way to tell from HP-UX. You have to ask your storage administrator. The disk array(s) may be going through a SAN switch so control of the ports that are presented to your HP computer are under control of the switch.

Hi,

you could try using a product like HP Storageworks SAN Visibility( free download from HP site), which will probe your SAN for you. It then sends a report to HP and they process the contents and then send you back a Human readable report on all attached LUNS,HBA firmware versions/type,OS type,etc and even a storage map.

hope this helps

regards

Matt

Shalom again,

Check the server hardware doc at http://docs.hp.com for information on the number of HBA cards the server can accept.

If you give model information I can look it up for you.

Dear sharlon,


we have HP rx8640 model and i understood that we can have more than 1 HBA for one server and its depend, but my question is that HBA is assinged a number called WWN NUMBER and we have more than one ports on one HBA card and each ports is assigned a number called WWp number, is it right ? there is fiber cable connectivity between fiber switch and HBA ports .clarify me if i am worn .thanks for your response.

@unixuser:

Now you are going to try here?

http://forums.itrc.hp.com/service/forums/questionanswer.do?threadId=1363034

You did not mention that you are using hp-ux.

As said earlier, each port of each HBA has a WWN, like NICs have MAC addresses.

You need to deal with the port WWN.

You can have as many HBA as your servers support, up to 196 in a fully equiped superdome.

Get the device files of all installed FC HBAs:

# ioscan -fnCfc

and you get something like td0 or fcd0

and now you can get the node and port WWN:

# fcmsutil /dev/fcd0
