If you get the line from /etc/path_to_inst, the HBA number will be the qla driver instance number i.e
"<path>" <instance> "<driver>"

The target is whatever you want to set it to - normally start at 0 and count up from there. I havent used the qla driver before (I find the Leadville based Sun drivers far more useable) but you might also need to bind any other targets on that WWN - some drivers disable auto-discovery if you enable persistant binding.

Hi,
I'm trying to persistently bind an auto changer connected to my server over 
fiber. the reason I wanna to that because every time I reboot my server the OS 
gives a different SCSI address (see below)  which causes problems with Legato 
Networker (the backup Application) and I have to reconfigure the jukebox all 
over again which is a pain in the ass. the closest I got to solve this problem 
is by persistent binding on the HBA level. to do that I need to compile a line 
and put it in the qla.conf the syntax if this line as follows:

hba<#>-SCSI-target-id-<#>-fibre-channel-port-name="<device WWPN>";

I got the hba # from /etc/path_to_inst and the device WWPN from the command 
inquire but I couldn't get the SCS-target-id.

Could somebody help me to get the SCSI-target-id? or suggest a solution for 
this problem.

Thanks
