server reboot

hi all,

for a reboot of sun box for patch installation i would like to know where do the reboot logs apart from /var/adm/messages and patch run messages would be available,

i would like to know the sequence of messages logged in the file like
requesting the users to log out
sending a shutdown message to all the connected users
dismounting the file system
then rebooting the system in single user mode
how would the network interfaces be affected not allowing anybody to telnet to the server ( as it is in single-user mode)
how the reception of ICMP packets are disabled for the time-being?
patch installation instructions ...

do all the sequence be logged in unison consequently as the work proceeds?

Hope i am clear with the question.

Thanks for your reply in advance.

Rebooting should send messages to your console - if you use some type of console connected to the system's serial port, then any logging would be found in that (example: my servers use conserver software - it logs anything going to the console in a log file set up via that software).

You can look at the man page for shutdown, boot, and init for info on the sequence - I didn't actually find anything that explains it (althought that may be due to the fact that there is no generic sequence since different servers boot up differently due to the hardware involved (E10K versus E4500 versus Netra).
