Veritas Storage Foundation Portable Data Containers: Cross-Platform Data Sharing 5.0.1 Administrators Guide, HP-UX 11i v3, First Edition, November 2009

■ Type the following command:
# vxdg flush diskgroup
This rewrites all labels except sectors 7 and 16.
To forcibly rewrite the AIX coexistence label in sector 7 and the HP-UX coexistence
label or VxVM ID block in sector 16
■ Type the following command:
# vxdisk -f flush disk_access_name
This command rewrites all labels if there exists a valid VxVM ID block that
points to a valid private region. The -f option is required to rewrite sectors 7
and 16 when a disk is taken offline due to label corruption (possibly by a
Windows system on the same fabric).

■ Changing the alignment of a disk group during disk encapsulation

Changing the alignment of a disk group during disk encapsulation
If you use the vxdiskadm command to encapsulate a disk into a disk group with
an alignment of 8K, the disk group alignment must be reduced to 1.
