or imagetype options in your dsm.sys. If you set the image type to snapshot, theclient performs a snapshot image backup of file systems residing on a logicalvolume created by the Linux Logical Volume Manager, during which the volume isavailable to other system applications. If you set the image type to static, the clientwill unmount and remount the volume as read-only, so that no other applicationscan access it. If you do not specify either of these options, the client performs asnapshot image backup.For the AIX, HP-UX, and Solaris clients, selecting the Image Backup optionperforms a static or dynamic image backup depending on the image type settingof the include.image or imagetype options in dsm.sys. If the image type is set tostatic, the client will unmount and remount the volume as read-only, so that noother applications can access it. If the image type is set to dynamic, the clientperforms the image backup without making the file system read-only during thebackup. If you do not specify either of these options, the client performs a staticimage backup.|To create an image backup of your file system or raw logical volume, perform thefollowing steps:1.

However, it will allow prior image backupsof LVM1 volumes to be restored on LVM2 volumes.
