Symptoms

Detailed description:
---------------------
After applying SRU11.3.3.6.0, our customer cannot use on-board DVD on SPARC T4.

Changes

The DVD disappeared after Update to 11.3 SRU 0.175.3.3.0.2.0 or greater

Cause

The issue is documented in :
Bug 22541794 :The physical DVD drive disappears after update

From the bug:
I looked into a T5-2 test system.
where in I could see that at level 0.175.3.3.0.1.0 DVD drive appears.
But once we upgrade to 0.175.3.3.0.2.0 DVD disappears.
From the code I can see that only bug 21425879 got integrated at
0.175.3.3.0.2.0.

Bug 21425879. has caused the regression.

The problem only happens on T4 and T5 or any platforms where the CDROM/DVD drives are now
connected using the mpt-sas driver

Solution

Fix delivered in Oracle Solaris 11.3.7.5.0 (or greater)
