We have recently bought a SAN to replace our old EMC disk array. As the first part of this project I will have to migrate data to the new SAN for a single HP-UX 11.0 server. VG00 on the Server is the only VG on the intenal disks, and on the other VG's we have lv's containing both filesystems and raw data.
I feel the only way to move all of this data is to use the dd command, and I'm not sure if I will need to do a vgexport/import?
Has anyone done this before, or does anyone know what the best plan would be to achieve migration?
Thanks, Alan

SolutionMirroring may be the solution (some conastraint anyway).
MirrorUX is required of course

Re: SAN Implementation
Then you can use lvol mirror's to copy the data.
So vgextend and lvextend then do a lvreduce from the old san disks for all the lvols in a vg.
Then do a vgreduce and the data should be on the new SAN.
