AIX and Flashcopy for backups

[J1gh2]

Hi Folks

I am having difficulty setting up flashcopy on AIX and wonder if anybody out there can help. The only way I have managed to get it to work is to recreate the target volume group after the flashcopy pairs has been established. I am using the following steps from the latest Redbook (sg24575704):

1) Varyoff the target volume group
2) Establish Flashcopy pairs with No background Copy option selected (does not work with other options such as incremental)
3) chdev –l hdiskX | vpathX –a pv=clear for all hdisks and vpaths involved on the target volume
4) Exportvg target_vg_name
5) recreatevg -y flashvg vpathX vpathX

Even though I am using version 2 a lot of features are not installed so it can only copy between volumes within the same LUN (LSS). IBM could only refer me to the redbook.

I am not happy about having to exportvg and recreatevg for this to work and the fact that it only works with No Background Copy option. Basically I can`t copy to a volume that already has data on it. I would also like to set this up so that incremental changes on the source volume are copied to the target, say, at scheduled intervals.

If you have been here before, or know of another way, I would very much appreciate your help. Thanks

We had to flash a 200Gb database from one server to another. We set up Flash Copy by establishing the flash coyp pairs and having the destination volume group varied off and exported. initiate the flash then import the vg using the importvg -y <VolumeGroup> <vpath>. varyon the Volume Group
