    In Solaris 11, yes this is possible. However, the open source community has not implemented it
    yet, AFAIK.

I know I can disable to the temp alert for that module but I don’t want to disable it for all disks, just these new Seagates.

    You can unload disk-transport altogether as a workaround. The root cause is a bug in
    the Seagate firmware introduced in version 3 of their firmware. A fix is in the works
    for version 4, available RSN.
