cloneable driver must be the clone driver's major number, 72. The minor

The STREAMS/UX log driver is named strlog instead of log. The special
device file is /dev/strlog. strlog provides the same functionality for logging
as described in the UNIX SVR4.2 System Files and Devices Reference, with
the exceptions described below:
• The strlog kernel utility formats binary arguments before sending messages up
the stream.
• STREAMS/UX does not provide a separate console logger or /dev/console
device. strlog does not support the I_CONSLOG ioctl. strlog prints a log
message on the console if the SL_CONSOLE flag is set.
• The HP-UX log_ctl structure does not contain a pri field. Priority and facility
codes are not supported.
