Snapview clones and ASM on VNX
Hello,
We were using Time Finder BCVs(sync/split) operations to provide our Oracle team database cloning capabilities. We are migrating that data off of the Symmetrix to the VNX. We will be using snapview clones to accomplish this. I have used clones in the past, however, those clones were related more to mount points under veritas where I would import the disk groups and remount the file systems. These source and clones are disks under ASM and so I am unsure where to go from here.
What I have done so far:
create the clone groups
added the source luns to the proper storage group
created the clone luns
syncronized and administratively fractured the clone luns
added the clone luns to the proper storage group
Here is where I need direction.
I remember from the past I do not format the clone disks presented.
So how do I get them into ASM and would I still do kpartx on them?
Many thanks!

i assume it's RedHat, probably does not matter as this is Oracle function
1) shutdown database on target host
srvctl stop database -d DBNAME
2) Dismount ASM disk group on target host
alter diskgroup DGROUP1 dismount
3) Perform VNX clone fructure
4) Remount ASM disk group on target host
alter diskgroup DGROUP1 mount
5) Start DB
srvctl start database -d DBNAME

One silly question. The OS is redhat. Do I have to run fdisk on the clone luns? I remember not having to do this using veritas, however, we weren't using RAC either. I usually use fdisk, kpartx, before adding the disk to asm, but I wasn't sure if I needed to do that. I would assume so.
Thanks again!

nope, you don't want to do that because that will destroy ASM header. You use fdisk when your provision brand new LUNs.
