The vxformat utility automatically relabels the virtual disk backed by a VxVM volume in the guest domain

The vxformat utility provides the user the ability to automatically relabel a virtual disk backed by a VxVM volume. This utility is meant to be executed from inside the guest domain only.

The vxformat utility is particularly useful when a VxVM volume with existing partitions is grown in size and you need to access the new size from the guest domain.

Requirements for relabeling to succeed

  • The relabel succeeds only- if it can find a new cylinder size that is aligned with the start and size of each of the existing partitions.

    In case the vxformat command cannot find such cylinder size, it displays the following descriptive message and then exits:

    Cannot re-label device /dev/rdsk/c0t1d2s2 since we failed to 
find new cylinder size that's aligned with all the existing 
partitions

  • The relabel succeeds only - if the available blocks is greater than the last sector of each and every non-s2 partition.

    Otherwise, thevxformat command displays the following message and then exits:

    Cannot re-label device /dev/rdsk/c0d2s2 since the last sector of a 
non-s2 partition is greater than the available blocks
