the easiest way would be to use the command "sys-unconfig". The sys-unconfig command is used to restore a system's configuration to an "as-manufactured" state, ready to be reconfigured again after a reboot. The system's configuration consists of hostname, Network Information Service (NIS), domain name, timezone, IP address, IP subnet mask, and root password.

hi pressy,

thank you for your response, btw is it affect with the mirroring disk or some server configuration? of the sys-unconfig just reconfigure for network only ?

thank you

Are you using mirrors?
Check the output of "metastat", just in case
Perhaps you need some "metasync" or have some kind of error in your mirros...

Regards.

from the manpage:

sys-unconfig does the following:

o Saves current /etc/inet/hosts file information in
/etc/inet/hosts.saved.

o If the current /etc/vfstab file contains NFS mount
entries, saves the /etc/vfstab file to
/etc/vfstab.orig.

o Restores the default /etc/inet/hosts file.

o Removes the default hostname in /etc/hostname.interface
files for all interfaces configured when this command
is run. To determine which interfaces are configured,
run the command 'ifconfig-a'. The
/etc/hostname.interface files corresponding to all of
the interfaces listed in the resulting output, with the
exception of the loopback interface (lo0), will be
removed.

o Removes the default domainname in /etc/defaultdomain.

o Restores the timezone to PST8PDT in /etc/TIMEZONE.

o Disables the Network Information Service (NIS) and Net-
work Information Service Plus (NIS+) if either NIS or
NIS+ was configured.

o Removes the file /etc/inet/netmasks.

o Removes the file /etc/defaultrouter.

o Removes the password set for root in /etc/shadow.

o Removes the file /etc/.rootkey.

o Executes all system configuration applications. These
applications are defined by prior executions of a
sysidconfig -a application. (See sysidconfig(1M)). When
sys-unconfig is run, all system configuration applica-
tions are passed one argument, -u.

o Removes the file /etc/resolv.conf.

o Disables LDAP by removing /var/ldap/ldap_client_cache,
/var/ldap/ldap_client_file, /var/ldap/ldap_client_cred,
and /var/ldap/cachemgr.log.

o Regenerates keys for sshd(1M).

When sys-unconfig is finished, it performs a system shut-
down. sys-unconfig is a potentially dangerous utility and
can only be run by the super user.

hi pressy,

thank you for your advice is very helpful
