Question

vxdisksetup format=sliced|simple|cdsdisk ? what are the differences?

I cannot find a definition for each type of format.

cdsdisk seems straight forward, that is concantinated. So the data and partitions stay intact.

But I don't really get sliced and simple.

What I am wondering is why I can only (on 4.1) vxrootmir rootdisk when i have:
vxdisksetup -i c1t0d0 format=sliced

If I try that with with a cdisk it fails.

So todo this step I need sliced, and am not sure why.
Re-attach the mirror in the correct order according to the partition layout:
vxrootmir rootdisk
vxassist -g rootdg mirror swapvol rootdisk
vxassist -g rootdg mirror var rootdisk

Thanks!
