persistent binding for autochanger

Hi,
I'm trying to persistently bind an auto changer connected to my server over SAN. 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 Networker and I have to reconfigure the jukebox all over again, which is a pain in the back. 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=" ";

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

    I used lputil years back and id obtained was via inquire command (scsidev@b.t.l). Depending on OS, you can use OS tools as well to get same information.

    2 is bus or your lpfc... 9 is target. I never used qlc so can't be sure of exact configuration parameters, but following link seems to give an answer to your questions:

    But I thought in Solaris 10 you could use alias to control port (thus port could change)?

    the numbers in bold is the one keeps changing
    scsidev@2.9.3:ADIC Scalar i2000 402A|Autochanger (Jukebox),
    /dev/scsi/changer/c2t500308C001C398B3d3

    the system OS is solaris 10
    Is 9 my SCSI id is this case?
    Is there any thing else I need to make all right other than putting this line in qlc.conf?
    Is there documents that explain this issue more?

    Thanks for the your response
