Appendix
A
Transferring data between
platforms
This appendix contains notes on considerations for data transfer between
operating system platforms with different inherent characteristics.
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
HP-UX, importing a shared disk group will result in the volumes being active
and enabled for shared-write. In the case of HP-UX, the shared volumes will be
inactive and require other actions to activate them for shared-write operations.
