Could be just about anything.....

Can you telnet to the server ?

If not then we will start troubleshooting using the console. Do you have acces to the console.

Wait... answer question 1 before we start this long thread.

Can you access via other means? FTP? SSH?

Are you attempting to ping from the same subnet or a different one? Do you have a default router set up?

More info is definitely needed.....

I have given my IP as 10.3.93.100
and the subnet mask as 255.255.255.0

Can you ping your default route ?

show it with netstat -rn.

It should be
show it with netstat -rn.

It should be 10.3.93.x .

did you include a hop count of 1 in the default router config ?

e.g.
route add default 10.3.93.x 1

need to set it in /etc/rc.config.d/netconf to be permanent.

Do a 'lanscan'. What interfaces do you have and what is their status?

Do an 'ifconfig lan?' for the interfaces to make sure they are configured how you think they are.

Can you ping anything FROM this server?

Is there a firewall of sort installed by default? I think 11.31 may do that.

Check your default gateway entry in netconf file. It may be missing.

Check netstat -rn

Thanks

Do I have to do anything from the nwtk end...

I have only connected the DHCP cable th the server's cisco switch,.

And As I have installed an OS for a development team to use..

What are the other things I should take care of on a newly built system. As in like the system has a OS installed and a VG01 in it.

This is still the BL860c, right?

Are all 4 NICs connected to a switch? Which NIC did you configure?

Where is the other server that you trying to ping? Also inside the blade enclosure?

Well on we go with your adventure into installing Integrity blades - overall I think we can say that you were completely un-prepared for this journey, and you should feed that back to your boss. Installing and implementing blade systems can at the outset be much more complex than standalone systems - that's because so much of the config is designed to be lights-out configured through automated processes like ignite / rdp etc.

Also installing blades is a multi-disciplinary task in that knowing about HP-UX is not enough (as you've already found out).

Now you need to get networking configured - in this case your Cisco switch. This isn't a dumb little managed switch like you might buy for your home from the local electronics store, its a fully fledged managed cisco catalyst switch running IOS. Just plugging cables into it won't work - it needs to be configured - and if you want to attach it to your existing corporate LAN you need to ensure its configured in-line with the other switches in your environment (same VLANs, routing protocols etc.)

I'm guessing you have a 3020 rather than a 3120 , so a good starting point would be here:

http://www.cisco.com/en/US/docs/switches/blades/3020/hardware/quick/guide/3020GSG2.html

If it is the 3120 start here instead:

http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c01430321/c01430321.pdf

And if you need to attach it to your corporate LAN I'd think very hard about getting one of your networking colleagues involved to help you configure the switch (breaking whole networks is pretty easy when attaching badly configured switches).

In fact consider stopping your whole install process and spend your day reading the relevant installation documentation for all your blade components here:

Hello,

a) It is obvious that only one LAN cards is
configured - lan0 at IP address 10.3.93.100.

b) here is something that I have seen
on many projects. HP-UX 11.31 server
was built with Bastille at DMZ level.

What does this command say:

# bastille -l

If the network cabling is OK and it is not
the swithc issue, then I am willing to
bet that your Bastille setup is too strict.
When Bastille is set to DMZ level, then
you cannot ping the HP-UX server or
telnet, or ssh...

To "udo" the Bastille setup for the moment,
you can just do the following:

# bastille -r

I do not have the HP-UX server in front of
me at the moment (I am teaching HP-UX SNA I
so I am having a coffee break), but I guess
bastille is in
/opt/sec_mgmt/bastille/bin directory...

Cheers,

VK2COT

while doing "Express setup" using the Onboard Administrator... I get the error the IP address x.x.x.x is conflicting with already assigned IP address of the following interface:-

Interface Ipaddress Netmask
FastEthernet0 x.x.x.x 255.255.255.0

What exactly are you now trying to set up? I'm not familiar with "Express Setup".

Re: Unable to ping my server which is up and running

Grayh — Fri, 12 Sep 2008 16:06:12 GMT

Actually I am trying to configure the cisco 3020 switch so that the server can be recognized in the network..

On the left hand side of the hp ONBOARD ADMINISTRATOR "express settings" which was givben in the doc...

and i enter the Ip address and it conflicts..
