Raw logical volume move from HP-UX to Linux

Is it possible to move raw logical volumes from HP-UX over to Linux and still be able to access the data? I have an Informix database that I need to move from HP-UX over to a Linux server.

Re: Raw logical volume move from HP-UX to Linux

Hello Cary,

THe correct way is to backup (export) the Informix Database in HP-UX & import back into Informix Database Server Linux.

You may try to 'dd' from HP-UX into a file and 'dd' into Linux Disk(s) or LV but the Informix Database Server in Linux may be expecting a different Database Internal Format as compared to HP-UX OS.

Shalom,

No, you will not be able to access the data. LVM on Linux was a feature port. The two LVM's did not come from the same source code.

You will need to follow above instructions, export the database and then import it on Linux.

It looks like dbexport/dbimport is about the only solution. Thanks for the input.
