[scient]

Hi all,

if your SAN disk belongs to another volume group than moved filesystem exists on, then you can use cplv command to move filesystems between volume groups:

[Chapter11]

assuming you can add the SAN-based hdisk to the same VG as the filesystem:

extendvg universevg hdisk42
migratepv -l booklv hdisk2 hdisk42

Substitute in your own names as appropriate.

You can do that live and hot without users knowing other than a slight i/o performance degradation.

Using the LVM and mirror copies to shuffle data around between various storage types is one of the really nice things about disk management in AIX.
