Storage Foundation and High Availability Solutions support for Oracle VM Server for SPARCUsing Veritas Volume Manager snapshots for cloning logical domain boot disks91To clone the boot disk using Veritas Volume Manager snapshots1 Create a snapshot of the source volume bootdisk1-vol. To create the snapshot,you can either take some of the existing ACTIVE plexes in the volume, or youcan use the following command to add new snapshot mirrors to the volume:primary# vxsnap [-b] [-g diskgroup] addmir volume \[nmirror=N] [alloc=storage_attributes]By default, the vxsnap addmir command adds one snapshot mirror to avolume unless you use the nmirror attribute to specify a different numberof mirrors. The mirrors remain in the SNAPATT state until they are fullysynchronized. The -b option can be used to perform the synchronization inthe background. Once synchronized, the mirrors are placed in the SNAPDONEstate.For example, the following command adds two mirrors to the volume,bootdisk1-vol, on disks mydg10 and mydg11:primary# vxsnap -g boot_dg addmir bootdisk1-vol \nmirror=2 alloc=mydg10,mydg11If you specify the -b option to the vxsnap addmir command, you can use thevxsnap snapwait command to wait for synchronization of the snapshotplexes to complete, as shown in the following example:primary# vxsnap -g boot_dg snapwait bootdisk1-vol nmirror=2
