urgent help needed in configuring X1151A
for RAC requirements I have to configure this card to use the interface name of ce1 but I have tried changing slots and puting /etc/hostname.ce1 file out there but it fails .. it always comes up as ce0.
my question is : How can I cofigure this card to come up as ce1 ? in the other box I had to do nothing .. i just placed the /etc/hostname.ce1 file with hostname and it works perfect.
can you please email me a copy of your response at sahmad43@hotmail.com ?
thanks
Sami

Don't post the same question to multiple forums.
http://forum.sun.com/jive/thread.jspa?threadID=110516
(plus this thread we are viewing right now)
... neither of which is in a forum for cluster configurations, by the way.
You'll never be certain where the correct answer might appear.
Perhaps that other system,
(which you never provided any details about)
already has an entry in its path-to-inst file for a ce0 interface.
Thus the new card could be configured as its next-available instance, and the installation error actually exists over there.

For the discussion in this forum thread, the path-to-inst file
can be though of as a repository of every device path
for every lump of hardware that was ever installed to a system.
It tells Solaris where to find the devices, along their communication interconnect paths.
Thus a device driver can know where to sends its commands
and where to listen for any return signalling responses from the device.
Issues can arise if a device was successfully installed to a path,
such as when a PCI card is installed to a particular slot,
and that card gets moved to another slot.
The path-to-inst file will "remember" the old path, in case you return the card.
No software structures need to be re-built when it reappears in its old slot position.
The former functionality is maintained if ever needed again.
The new position initiates a new entry into the file,
such as when there are two of the same cards instead of the original solitary card.
For your circumstances, there's got to be something in the computer's configuration
that can isolate the data streaming to IP address #1 ( such as for ce0 )
from whatever data might need to go through the other IP address ( such as for ce1 ).

My suggestion for you is to use the devfsadm command.
Review its man pages.
Decide how you want the computers to be configured -- probably using ce0 on both.
devfsadm -C will purge out stale entries and rebuild the path-to-inst file.
A reconfiguration reboot, such as might result from a boot -r,
only appends new device instances to the file.
There's no cleanup, or 'housekeeping', done to it.
