Hi,
I try to do a restoration from an mksysb tape of 6H1A, the restoration was successful.
But when the system rebooted, the hostname and ip addresses is lost.
Anyone can give a pointer on the reason(s) ?

Thanks,

How and when (in the life of the machine the mksysb was made on) was the mksysb made?

Could it have been made just after install before the hostname and ip address were configured?

sorry forget to mention...
it is a mksysb of another system (6C4), a production system made a few day earlier.
i have done an restoration earlier, everything was perfect.
but this time round, the hostname and ip addresses just get lost.

Thats a case where the mksysb works as designed. The IP address and hostname will only come back if the mksysb is reinstalled on the original hardware. It will identify the Ethernet adapter on your new system as having a different ethernet card and it will therefore not have the same MAC address and will not have the IP address allocated to it.

hi ross,

cannot be the case.
i have been doing it for awhile.
whenever a customer bring their mksysb tape and restore at our server, even though the model is different, we still manage to get the hostname and ip addresses intact without any problem.

there must be other answers or problems.
will someone kindly offer some other reasons.

thanks

Ross is 100% correct. I just completed a job for a client where I migrated 33 LPARs from various servers to two p595s to help them same floor space, power and cooling. All LPARs were created from their original server by MKSYSBs, but the original server had to remain up and functional until a coordinated cutover time.

The LPARs were installed via NIM, so from SMS, I define a client IP address. It is the client IP address defined in the SMS IPL menu that becomes the IP address, not what is on the MKSYSB.

Are you installing via NIM or using a CD/DVD?

i am in the DR/BC industry.
i also have been doing it for quite awhile.

Yesterday I just did another restoration from an customer's mksysb tape with the help of an OS CD (AIX 5.2 ML4)

Customer's configuration at their production:

# ifconfig -a
en0: flags=5e080863,80<UP,BROADCAST,NOTRAILERS,RUNNING, SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD,P SEG,CHAIN>

As their image is larger than 12MB, so I have to boot from OS CD AIX5.2 ML4 and then restored from it.
The server allocated for their testing is 7028-6C4, 4x1.25GHz, 8GB RAM
When the server come-up, nothing was lost, the hostname and ip address was still intact.

Anyway, thanks for the kind assistance rendered.
