Move system ( and Applications ) to a different host

[samir_24]

Hi All,

I want to move the system (and the Applications)that it contains to a different - less configuration- Machine (host).

Is there any way or tool to do this , I know that the ignite tool does not work in this case.

I want to do this because it is so difficult to install such this system again...

Can Anyone Advice.!!!!!!!!!!

Thanks in Advance.

Samir.

Ignite can do the job.

You can create a golden image or a make_tape_recovery including the volume groups of the application volume group with the database down.

Then do an interactive Ignite reocvery on the other host, changing the hostname and other details as needed to fit the situation and disk layout.

Thanks Steven for your prompt replay ..

But the H/w (Devices) - including num of processors- in the two Machines are different.

I tried something like this before and I failed ..

SEP ,

will he need to make frecovery after successful ignite recovery ????

in case of data shunks , is it will be enough?

I think he will need an intact full application backup to restore database files.

Well if your data/software is on disks that can be seen by both hosts...you could just vgexport the vg involved to a mapfile from the first host and then vgimport the mapfile into the other host.
De-activate on the first server the vg.
Activate on the second server in exlusive mode..

vgexport -vs -m /etc/lvmconf/vgname.mapxx /dev/vgname
copy this mapfile to the other host
vgchange -a n /dev/vgname on the first host
On the second host...
mkdir /dev/vgname
mknod /dev/vgname/group c 64 0x_ _ 0000
vgimport -vs -m /etc/lvmconf/vgname.mapxx /dev/vgname
vgchange -a e /dev/vgname
mount /dev/vgname

...now see if you can fire off the application..Some software is 'aware' of the server it is on, or licensed accordingly. So you may need to adjust a couple things. Check with the software provider to check on this..

HTH,
Rita


...of course if you had MC/SG you could just have 'failed' over to the other server and done it all in 1 to 2 simple commands....

Thanks Rita,

But I think that is so difficult with some Applications espacially that uses oracle DB.

And if I have a software provider , i ll install the old system from scratch.

Steven ,

You say "create a golden image " is this differ from the ignite.

And is the interactive recovery will fix the differences bet. the two hosts ?

Thanks
