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.
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.
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?
7026-6H1 is a P660, is this an lpar on this machine, I should think so. Run prtconf | more on the second system and cut and paste the top 15 lines into your reply.
I think there is no lpar on 660. You can take a backup and restore it to the other system. You have to create the lv s by yourself. After that you can use lvmirror or lvcopy. Or if you want to change the sizes of lv s you can take a backup by TSM or smt. and restore it to the other system.
OMG!
big job
can you upgrade the p660 to 5.2, to then take a mksysb and then do a migration install on to the p590 LPAR? or do you need to leave the p660 intact at 4.3? (the p590 will not support 4.3)
do the applications on the p660 run on AIX 5.2?
if you need to leave the p660 at 4.3 you will need to start from scratch for the rootvg and the applications on the p590.
