Mirroring Disks in Veritas Volume Manager

[nitinkgoud]

Hi guys,
I need to mirror volumes using VVM.
How ever the volumes are present on both the disks.
eg
volume V1 is on disk D1 and V2 is on D2.
Now i need to move V2 to D1 and mirror D1 and D2.
Now my question is will VVM generate error message if there is insufficient space on D1?
or will i loose data?

please help.

You would not lose data, vxvm would say something like 'not enough space to mirror nnnnnnn block volume'.

But you can check beforehand whether you have enough space on the disks using vxdg free. vxprint -vA would show you the sizes of the volumes on your system in blocks. Blocks in vxvm are 512 bytes.

You don't need to "move" V2 to D1, you can just mirror V2 to D1, and mirror V2 to D2.
