Confused with entries in /etc/hostname.<interface> file...

Hi.. Every one,

I have servers installed with solaris 10.We have configured our servers for IPMP and we have respective entries in /etc/hostname.<interface> for every physical interface.
for example one of the file contains :

Code:

# more /etc/hostname.ce6
super-ce6 netmask + broadcast + group accgrp deprecated -failover up addif super-dummy netmask + broadcast + deprecated up

Can any one explain me what these entries do...????

What is the purpose of " addif " and " -failover " also why two " up "
are used.

Code:

o/p of ifconfig -a :
 
# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
ce5: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 3
        inet 10.66.23.112 netmask ffffff00 broadcast 10.66.23.255
        ether 0:14:4f:67:cb:d3
ce6: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 4
        inet 10.66.22.74 netmask ffffff00 broadcast 10.66.22.255
        groupname accgrp
        ether 0:14:4f:69:c2:c8
ce6:1: flags=1040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4> mtu 1500 index 4
        inet 10.66.22.108 netmask ffffff00 broadcast 10.66.22.255
ce6:2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
        inet 10.66.22.64 netmask ffffff00 broadcast 10.66.22.255
ce10: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 2
        inet 10.66.22.84 netmask ffffff00 broadcast 10.66.22.255
        groupname accgrp
        ether 0:14:4f:69:c2:e0

 
o/p of more /etc/hosts:
 
# more /etc/hosts
10.66.22.64     super  loghost 
10.66.22.74     super-ce6
10.66.22.84     super-ce10
10.66.22.108    super-dummy
10.66.23.112    super-ce5

Thanks in Advance.....

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
