Hello,
I have root disk of 18 gb and 4 other disks of 8 gb each. I want to mirror the root vol but don't have another disk of same geometry, is it possible to do so, if so please advice.
Following is my vxprint, i have already encapsulated root disk but get the following error when trying to mirror.Also is it mandatory to have the second disk in the same diskgroup i.e rootdg?
bash-3.00# vxprint -ht
Disk group: rootdg
