Mirroring rx2620 (Itanium with HPUX 11.23)
This is a discussion on Mirroring rx2620 (Itanium with HPUX 11.23) within the HP-UX Operating System forums, part of the Unix Operating Systems category; --> Hello do you have any ideas ? I think it is different to PA-RISC Servers. Thanks Ralf...

Do you mean disk mirroring ? - Is is equal on all hpux systems. You need MirrorDisk/UX or use Vertias Volumemanger. For MirrorDisk/UX is a seperate license needed. I am not shure, but the Veritas Volume Manager bundled with hpux can do mirroring. Lars      |
