66Storage Foundation and High Availability Solutions support for Oracle VM Server for SPARCFeaturesTo use this vxloadm utility1 Load the vxlo driver in memory:# cd /kernel/drv/sparcv9# add_drv -m '* 0640 root sys' vxlo# modload vxlo2 Check if the driver is loaded in memory:# modinfo| grep vxlo226 7b3ec000 3870 306 1 vxlo (Veritas Loopback Driver 0.1)3 Run the vxloadm utility:# /etc/vx/bin/vxloadm4 You can now use the utility.See “Examples of using the vxloadm utility” on page 66.5 Symantec recommends once you are done using the vxloadm utility to unloadthe vxlo driver:# rem_drv vxlo# modinfo| grep vxlo226 7b3ec000 3870 306 1 vxlo (Veritas Loopback Driver 0.1)# modunload -i 226where 226 is the module ID from the modinfo | grep vxlo command.Examples of using the vxloadm utilityUse the vxloadm addall command to create device(s) mapping the variouspartition(s) contained in a VxVM volume. For example:# /etc/vx/bin/vxloadm addall vol1 /dev/vx/dsk/testdg/vol1This creates a device node entry for every slice or partition contained within thevolume in the /dev/vxlo/dsk/ and /dev/vxlo/rdsk/ directories.# ls -l /dev/vxlo/dsk/lrwxrwxrwx 1 root root 46 Sep 25 14:04 vol1s0-> ../../../devices/pseudo/vxlo@0:vol1s0,1,blklrwxrwxrwx 1 root root 46 Sep 25 14:04 vol1s3-> ../../../devices/pseudo/vxlo@0:vol1s3,2,blk

For example:# fstyp /dev/vxlo/rdsk/vol1s0ufs# mount -F ufs /dev/vxlo/dsk/vol1s0 /mntUse the vxloadm delete to remove the partition mappings of a volume. Forexample:# /etc/vx/bin/vxloadm delete vol1s0# /etc/vx/bin/vxloadm delete vol1s3Note: This vxloadm utility should only be used on volumes that are currently notin use or held open by a guest domain.The vxformat utility automatically relabels the virtual diskbacked by a VxVM volume in the guest domainThe vxformat utility provides the user the ability to automatically relabel a virtualdisk backed by a VxVM volume. This utility is meant to be executed from insidethe guest domain only.The vxformat utility is particularly useful when a VxVM volume with existingpartitions is grown in size and you need to access the new size from the guestdomain.Requirements for relabeling to succeed
