Moving disks between EVAs

Adrian Ogden — Mon, 07 Nov 2005 11:12:22 GMT

Hi
Is it possible to export and dismount a set of disks such that they can be taken to another EVA at another site (connected via a WAN) and used as a reasonably up to date CA destination copy?

The idea being that if the amount to copy is too great (e.g. full re-sync) then the disks can be put in the local EVA , syncd then taken to the remote site.

Or even use a backup to achieve the same thing?

No. You do need to replicate.

Well if you want to have total control of your replication solution and also avoid vendor/array lock-in (meaning it will not matter what storage you use) - take a look at Veritas Solutions that HP also support. One such solution is Veritas Volume Replicator - Of course you need to be using VxVM to do this.

With VVR, you can use tapes or portable disks to create your initial copy at your replicated site. One your copy is there - then fire up VVR which will transmit the deltas (changes) either synchronously or asynchronously.

Yep, do that already on another system but if you have a lot of hosts then you don't have cross host write ordering and also a lot of managing to do.

I would like to replicate the non page file part of the boot disks as well that VVR doesn't do.
