SUMMARY: How to change the number of the pseudo devices?

We had to increase the number of the pseudo devices but couldn't. The
solution of this problem is to set the variable pt_cnt in /etc/system:

set pt_cnt=<value>

Don't follow the book Solaris 2.3 Administering Security, Performance,
and Accounting. It states, that you have to set this variable by

set tune:pt_cnt=<value>


Finally, you HAVE to reboot by 'boot -r' to force the system to rebuild
the /dev and /devices directories.

Many thanks to

Colin Campbell <>

who helped me to find the 'boot -r' trick.
