Thank you; I'll investigate using hotplug/udev. It's already installed, I'd just have to write a udev rule and the script.
But if hotplug gets triggered when I attach a dasd why is it only some dasd addresses get automatically enabled and appear as /dev/dasd? after I attach one while Linux is running? Is the hotplug action limited to only the dasd addresses defined on the kernel parameter line, like dasd=200-20F ? -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

Hotplug (or udev) gets triggered when you define/attach/detach a device. Although it is not the nicest way of signalling, yes you could abuse hotplug or udev to trigger an action (e.g. by defining a virtual ctc device and intercepting this with hotplug or udev). -- Mit freundlichen Grüßen / Best Regards Christian Borntraeger Linux Software Engineer zSeries Linux & Virtualization ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
