Displaying offset and length information in units of 512 bytes
To display offset and length information in units of 512 bytes
◆ Specify the -b option to the vxprint and vxdisk commands, as shown in
these examples:
# vxprint -bm
# vxdisk -b list
Specifying the -b option enables consistent output to be obtained on
different platforms. Without the
-b option, the information is output in
units of sectors. The number of bytes per sector differs between platforms.
When the vxprint -bm or vxdisk -b list command is used, the output also
contains the b suffix, so that the output can be fed back to
vxmake.
Default activation mode of shared disk groups
The default activation mode of shared disk groups involves a local in-kernel
policy that differs between platforms. This means that, 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 results
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.
