AIX

Hi everybody,

I want ask if it is possible to copy all storage structure (VGs, LVs & filesystems) from one server to another. In other words, I want to move my system from old server to new one, so I want the new server exactly have the same sizes and number of VGs, LVs, & filesystems.

Thanks in advance.

From what to what? Model numbers would help.

AIX level might help too.

mksysb -m can do this, you will also need to do the non-rootvg volume groups with savevg -m

as johnf says though, the new machine must support the AIX level of the old machine, or vice versa if you need to upgrade the old machine AIX level to a later level, that the new machine supports, before the migration.

If the operating system is built up on the new system,
The things you have to do are

on the old system;
1-Unmount the filesystems
1-Varoff the vg s
2-Export the vg s
3-Remove the vpath and/or hdisk definitons from old system

on the new system;
1-Give the disks to the new system from disk management
2-Change the zoning on the SAN switch
3-If needed install SDD or MPIO and host attachment scripts
3-cfgmgr
4-Get the pvids with chdev
5-Import the vg s on one of the disks
6-Mount the filesystems


The structure is the same as the old one. All things including data. No risk of data corruption. If you give details about the systems I can help more. I can give the commands if you give the structure.

samaks,
only if the non-root vg's are on san storage, if they are on internal disks....see my last post.

I think more details should be given by aldowsary. aldowsary talks about storage and I didnt think storage would be on internal disks. By the way we have to wait the answer.

Quite correct we have to wait for an answer. He might want to move from an old 43P to a P510 for all we know. Also storage is storage whether external or internal so he needs to clarify both points! As I said in my first post from what to what?
