Is it possible to have different passwords for each of the devices connected into a Switch Fabric? In particular could one have separate and distinct passwords for each of the HBAs connected to a MDS 9000 Switch?

I assume you mean for the FCSP protocol? If so, then yes. I have not done it with HBA's, but I have done it with different switches. I had to give each MDS it's own username and password in the MDS configuration. For using FCSP between the switches, the username is the switch WWN.

Hope this helps,

yes I meant FCSP - whilst using DH-CHAP. What we want to do is have a number of HBAs connecting to a switch - but for a set of HBAs to have one password - and another set of HBAs to have a nnumber password. Hence we require the switch to be able to be configured with a password per port/interface.

Make sense, what I suspect you will need to do is configure each HBA PWWN as a device name along with the desired password for that HBA. As I noted, I have not done this with an HBA so I'm not 100% sure what to configure for the device name. The HBA documentation should explain how to configure the device name and password.

This is what I had to configure for my 9216 to do FCSP with a 9509.

fcsp enable

fcsp dhchap password 7 upt92161

fcsp dhchap password 7 upt92161 20:00:00:05:30:00:51:1e

fcsp dhchap devicename 20:00:00:05:30:00:51:1e password 7 upt95091

Also have to enable FCSP on the interface.

The device name in this existing

I used the term username previously, when in fact it should be deviceame.
