In COMSTAR the emlxs driver is only responsible for maintaining the FC link and acting as a pass-through IO driver for COMSTAR. It is not responsible for maintaining the SCSI Target or LUN’s. That is the responsibility of the COMSTAR fct and stmf drivers. If the driver is online and the link is up and you are seeing problems with LUN’s disaapearing I would suggest verifying your COMSTAR configuration using sbdadm and stmfadm. COMSTAR may have disabled a LUN or a Target for some reason and it needs to be reinstated.
If you would like me to verify the emlxs driver, you can send me the emlxs debug messages along with the stmf debug messages at the time of the problem. To obtain the complete emlxs driver debug messages just add the following line to your /kernel/drv/emlxs.conf file, reboot, recreate the problem and save a copy of the /var/adm/messages file on your host. It will contain the driver’s debug messages. You may want to empty the /var/adm/messages file before rebooting so the file is not too big. log-debugs=0xFFFFFFFF; Immediately after recreating the problem you can collect the stmf debug messages by entering the following command on the command line. It will place a copy of the stmf debug messsages into a file called stmf.log. echo “*stmf_trace_buf/s” | mdb –k > stmf.log Once both files have been collected just tar and compress the two files together and send them to me. If the files are too big for an email, then contact me by email and I can provide an ftp address for you to use.
