68Storage Foundation and High Availability Solutions support for Oracle VM Server for SPARCFeatures■The relabel succeeds only- if it can find a new cylinder size that is aligned withthe start and size of each of the existing partitions.In case the vxformat command cannot find such cylinder size, it displays thefollowing descriptive message and then exits:Cannot re-label device /dev/rdsk/c0t1d2s2 since we failed tofind new cylinder size that's aligned with all the existing partitions■The relabel succeeds only - if the available blocks is greater than the last sectorof each and every non-s2 partition.Otherwise, thevxformat command displays the following message and thenexits:Cannot re-label device /dev/rdsk/c0d2s2 since the last sector of anon-s2 partition is greater than the available blocksExample of using the vxformat utilityUse the vxformat command to relabel the virtual disk. For example:# /etc/vx/bin/vxformat c0d1s2rawpath: /dev/rdsk/c0d1s2Old disk capacity: 2097000 blocksNew disk capacity: 4194000 blocksDevice /dev/rdsk/c0d1s2 has been successfully re-labeled.Please use prtvtoc(1) to obtain the latest partition table informationIf the underlying device size has not changed, the vxformat command displaysthe following message without changing the label. For example:# /etc/vx/bin/vxformat c0d1s2Old disk capacity: 2343678 blocksNew disk capacity: 2343678 blockssize of device /dev/rdsk/c0d2s2 is unchangedOracle VM Server for SPARC featuresSFHA solutions support the following features for Oracle VM server for SPARC.Guest domain migrationThe guest domain migration feature is supported for cold, warm, and livemigrations by Storage Foundation with both deployment models:■Split Storage Foundation stack

Thisadjustment of the label needs to be done carefully.Split Storage Foundation stack modelFigure 4-1 illustrates the split Storage Foundation stack model with Oracle VMServer for SPARC logical domains.
