connectivity problem after mksysb install on different host

hi,
i have a p550 running oracle other aix 5.3 on full partition system and we need to create a backup server with the same config on another p550 with lpars . i used a mksysb install to install one of the lpar. but after install i 'm not able to ping the new install lpar even when i tried to change the ip address with smit tcpip on en0. i'm able to login trough the HMC . last solution i tried it's to reinstall the lpar with an Aix 5.3 dvd. but i faced the same connectivity problem

I'm rather sure that due to changed hardware location codes ent0 (en0) is no longer available to your system.

You should have got a new interface, probably ent1.

Check with

lsdev -Ccadapter

and use the entx (enx) interface which appears as "Available" to define your IP address.

You'll see that ent0 is still there, but does appear as "Defined".

If the above is not the cause for your issue:

- Is the LPAR's network connected over VIO (l-lan)?

If so, did you specify the correct VLAN ID for the virtual adapter while configuring the LPAR (HMC or IVM)?

- Or does the LPAR use real adapters?

If so, did you attach the correct slot and is the adapter in this slot indeed physically connected to the network?

my LPAR's use real ethernet adapter ( allow as desired) . and it's physically connected to network ( i got the server with an aix 5.3 installed on it and after connect it to the network and config the adapter it was running smoothly before i run my mksysb install).
the output for lsdev -Cc adapter is :

[ root@training2.serv2 / ]lsdev -Cc adapter
ent0 Available 01-00 2 ports Gigabit Ethernet-SX PCI-Express adapter (14103f03)
ent1 Available 01-01 2 ports Gigabit Ethernet-SX PCI-Express adapter (14103f03)fcs0
ent2 Available logical hosts ethernet port (lp-hea)
fcs0 Available 00-08 FC adapter
fcs1 Available 00-09 FC adapter
lhea0 available logical hosts ethernet port (lp-hea)

right !! i think it's an issue with config on HMC. but i got an mksysb copy ( of the faulty LPAR's) from backup team , i reinstall it , and everything is ok now. please give me more information about LHEA for further maintenance. thank.

I think you should read this first, in order to get a basic understanding of what HEA actually is:
http://publib.boulder.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/iphat/iphathea.htm

And here is a fine Redbook on that topic:
http://www.redbooks.ibm.com/redpapers/pdfs/redp4340.pdf

(IVE is the old, now obsolete term for HEA)

Should you have further questions afterwards, please don't hesitate to ask!
