10 "SEAGATE ST360057SSUN600G" 0A25 <================== Newer firmware
11 "SEAGATE ST360057SSUN600G" 0805

Changes

Replaced a bad disk with a new disk.

Cause

The new disk comes with latest firmware.

Solution

<Bug: 13796177> DRIVE FIRMWARE CHECKHWNFWPROFILE -C STRICT ALL DRIVES ARE NOT IDENTICAL

Extract:

0A25 is a higher firmware versions than 0805.
So, we may leave the disk, with the current firmware version. As long as we are equal or higher than the minimum firmware version, we are fine.
CheckHWnFWProfile basically compares the disk firmware versions with the hardcoded values, this might be the reason why we are seeing the errors, which can be ignored at this time.
When you upgrade your exadata, all disks will get the latest firmware.
