Using SANCopy with Oracle database
I have a need to migrate Oracle databases running on HP-UX off our CX700. I was thinking I could use SANcopy for this. Unix admin has advised me that his volume groups are a mix of CX700 and CX3-80 LUNs with the filesystem residing on that LV. My question is will SANcopy work since the volume group is a mixed and how do I ensure a consistant data when the mirror is split? Thanks.

pvmove would be the perfect tool to do this, online too.

For UNIX/Oracle - Use the host-based tools. You can do the migrations online.
If you use ORACLE ASM - There's a function to move the databases to the new disks
If you use VxVM - Then you can create a mirror on the new LUNs, then break the mirror and drop the old disks
Like dynamox suggested, pvmove also if that's an option.
None of those options require any downtime.

Thank you for the answers. We did a pvmove as our Oracle team did not want to help us in any way. pvmove worked with out any problems. Thanks again.

is it NOT recommended to mix arrays on the same vg? I have not seen there this on any best practice document. But i dont mix it like this in my environment.
