The operation to create a new extent on the universal device list, UDL, during the execution of crdl failed. The device name, device, offset value, offset, extent size, size, and configuration device, config, are printed in the message. If the QMCONFIG file exists, this command can fail if the file open fails; if a read on the device fails; if the file is not a configuration file; or if the file is not a normal file or a raw device (for example, a fifo file). If the file doesn't exist, the command can fail if file creation fails (for example, if the directory in which the file is to be created doesn't exist). The command can also fail if it failed to lock the configuration file; if there are no slots available in the UDL; if the extent to be created overlaps with an existing device on the UDL; if the first entry is being created and the device doesn't match QMCONFIG or the offset is not 0 or there is not enough space allocated to store the UDL and volume table of contents; or if a write fails on the device.
