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

Transferring data between
platforms
This appendix includes the following topics:
■ Alignment value and block size
■ Default activation mode of shared disk groups
■ Disk group alignment and encapsulated disks
■ Disk group import between Linux and non-Linux machines
■ Moving disk groups between HP-UX and Linux systems
■ Migrating a snapshot volume
Alignment value and block size
On the AIX, Linux and Solaris operating systems, an alignment value of 1 is
equivalent to a block size of 512 bytes. On the HP-UX operating system, it is
equivalent to a block size of 1024 bytes.
The block size on HP-UX is different from that on other supported platforms.
Output from commands such as vxdisk and vxprint looks different on HP-UX
for the same disk group if the -b option is not specified.
Default activation mode of shared disk groups
The default activation mode of shared disk groups is a local in-kernel policy that
differs between platforms. Regardless of the platform on which the disk group
was created, the importing platform will have platform-specific behavior with
respect to activation of shared disk groups. Specifically, with the exception of
