Identifying the disk offset for other hosts

Determine the disk offset for hosts that are not Solaris hosts, if you have them.

Prepare the LUN for storing Oracle data, for example, by setting up raw volumes.
On the host console, enter the following command:dd if=/dev/zero of=/dev/path_to_storage bs=4096 count=1 conv=notrunc
path_to_storage is the path to the LUN on the host.

The host writes an Oracle 4K block of zeros to the storage system.
Check the SnapValidator error message displayed on the storage system console. The error message displays the offset.
Example
The following error message example shows that the disk offset is 1,048,576 bytes.
```
