Creating device nodes for the z/VM recording devices

6.10 z/VM guest

You access z/VM® recording data through device nodes. Unless udev or your distribution create the nodes for you, you must create them.

If there are no device nodes, use a command of this form to create a node:

# mknod -m 440 /dev/<file> c <major> <minor>

where:

<file>: is the file name that you assign to the device node.
<major>: is the major number that was dynamically assigned to the z/VM recording device driver.
<minor>: is the minor number of the recording service for which you are creating the device node.

Example

Using the standard device names and assuming that the assigned major number is 254, you could create the device nodes like this:

# mknod -m 440 /dev/logrec c 254 0
# mknod -m 440 /dev/account c 254 1
# mknod -m 440 /dev/symptom c 254 2
