I thought it might worth sharing of my findings. Here is how I enabled FDMI on CentOS 6.8 with the latest / greatest drivers from HP: HPAJ764A FW:v8.02.00 DVR:v8.07.00.34.06.0-k1:

1. Enable FDMI on your FOS switch:

switchdisable configure

Configure...

Fabric parameters (yes, y, no, n): [no] yes ...

Display FDMI Host Name (yes, y, no, n): [no] yes <<<<<<<< type 'yes'

...

2. Verify the FDMI flag is enabled:

configshow -all | grep dmiHostname

switch.fdmiHostname:1

3. Issue a LIP command on FCP initiator (it could be an idea to add it to startup script):

// numbers below are system dependent, ie can start from 2, 3 etc.

for i in 1 2 3 4 ; do echo 1 > /sys/class/fc_host/host${i}/issue_lip; done;

Cheers, Vladimir

Yes, I'm after the hostname.

Apparently it fails to return utsname() structure, though running "uname" in Linux terminal works fine, my understanding these two should return the same data structure.

And doing "cat /sys/class/fc_host/host*/system_hostname" gives me empty entries for all HBAs, ie these structure are not initialized by default. Also simply changing /sys/class/fc_host/hostX/system_hostname doesn't change "FDMI Host Name", I guess it requires to re-initialize the drive to make an effect.

Here is a sample output I currently get, fetched via 'fdmishow' on Brocade 6510 running FOS v7.0.2d:

Assuming you mean HostName part - looking at current Linux kernel qla driver, it actually tries to return hostname as returned by utsname(); otherwise it falls back to using system_hostname per-FC adapter attribute. Again, in current kernel this should be exported via sysfs as

/sys/class/fc_host/hostX/system_hostname

And you should be able to set it via this sysfs attribute as well.

Hi,

I recently noticed that qla2xxx (Qlogic HBAs) driver on Linux is capable of reporting FDMI.

By default it sends "Linux-default", and I'm failing to see how to change it to actual host name as it becomes way more handy then =) Any ideas?
