Hi,
After testing the solution it seems not to work. Looking at the log I can see that udev is started before the root file system is in read/write mode. That means that none of my changes are taking affect. Where can I see that output of my script if it is running under udev? Does anyone has another idea how to change the zfcp WWPNs without editing system delivered scripts? Thanks!

Looking at a Redhat system here, i find that the script /sbin/zfcpconf.sh reads the configuration file /etc/zfcp.conf. This script is run from udev when the zfcp module is loaded in the kernel: # grep -r zfcpconf.sh /etc/ /etc/udev/rules.d/56-zfcp.rules:KERNEL=="zfcp_cfdc", RUN+="/sbin/zfcpconf.sh" If you wanted to change the configuration file before that step, you could add another file in /etc/udev/rules.d/ to run your script first, e.g. create a file /etc/udev/rules.d/55-local-zfcp-conf.rules with the line: KERNEL=="zfcp_cfdc", RUN+="/usr/local/sbin/update-zfcp-conf.sh" -- Christof Schmitt ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 No virus found in this incoming message.
