Infrastructure Software

hi all,

Thanks in advance.

I have Solaris 11 express on Sunfire V250 machine. It has SAN connectivity through fibre channel. I want to configure SAN devices on my own with the help of command devfsadm.

For this I created a .so library and put that library at /usr/lib/devfsadm/linkmod/ directory. In the library I defined a variable for the structure devfsadm_create_t and a function so that it will reconfigure the devices as per my requirement (names of the logical links etc.,). After putting the library I rebooted the Solaris machine with -r option(reconfiguration reboot).

Then at boot time during execution of above said library by devfsadmd(in daemon mode only), /dev/ directory is getting busy so that it is not able to read its contents and hence the machine is taking much time to boot around 45 minutes. However, that library is working fine with Solaris 10 on the same machine.

Please help me out with possible root cause and solution of the problem.

thanks and regards,
kumar
