LVM mirroring using different LUN size-from small Vdisk to bigger Vdisk
Has anyone faced with this situation? Please advise.
I have 01*700GB Vdisk in an OLD Storage (EVA400).
Now I have to migrate all data from the OLD Storage to a new Storage (EVA8100).
Can I migrate from 01*700GB (EVA4000) to 02*400GB (EVA8100)?
Any help much appreciate!

But I do not want to use pvmove!
Do you have another solution?

Re: LVM mirroring using different LUN size-from small Vdisk to bigger Vdisk
Can you tell how is your 01*700GB (EVA4000)disk is being used now!!
Also whether 02*400GB (EVA8100) disks will be in same configuration like your 01*700GB (EVA4000)disk is?
Taking backup and restoring is another option.
