What are commands to recover vdisk from snap clone ?

[Earl Einhaus]

I want to use snap clone to make a disk copy of my production database. I have that procedure down. I am looking for the steps necessary to restore from my snapclone back to the original vdisk. I realize that the snap clone is a snap shot until completetion and I have that hole there. The snap clone will not be mounted.
I caught a thread a couple of week ago in partially in regard to this, but I cannot locate it again.

Thanks

EVA snapshots and snapclones are available for use right after the creation. You can mount your vdisk and use it as a normal disk if you want, following the restrictions of the operating systems, like duplicate PVID for volume groups, domain ID for Tru64.

I want to use the snapclone as a disk backup. I would want to restore the snapeclone back to the original vdisk, not mount it.

A snapclone, once the copy is over, is a complete independend virtual disk.

You could remove the "original" from the host's presentation and present the "clone" instead.

Another possibility, depending on EVA model and controller firmware is to:
- unpresent the "original"
- turn the virtual disk into a container
- start a snapclone into this container
- present the "clone" to the host again

If you are using operating systems (OpenVMS, Tru64 Unix) / multipath software (e.g. Secure Path) that are working with Unit identifiers or LUN WWNs, you need to do additional work for a smooth operatin
