Sun Cluster 3.3 and /etc/reboot

Posted in Sun Cluster at 10:50 am by alessiodini

Today i’m studying Sun Cluster 3.3 documentation and i read this:

8 Reboot all nodes into cluster mode.
# sync;sync;sync;/etc/reboot

i was very surprised to see the command “/etc/reboot”.
I logged into 3.3 cluster and i founded this file! I founded this is a link to halt command … mmm.
So my questions are:

1) why /etc/reboot ?
2) does sun cluster 3.3 make this link ? or not ?

I want know đŸ˜›

    this link is preset in all systems solaris.
    is not created by Sun Cluster.
    This is also the command halt -> ../usr/sbin/halt.
    I use these commands in single user mode
