I have received three answers, but the problem was the scsi terminator.
Thanks at:
Andreas Ehliar
Bismark Espinoza

their answers were:

"we had similar problems spring this year. The combination of
Solaris2.6, an enterprise 450 and extern
scsi discs requires a patch for the solaris system.
I searched my mails with the SUN-support-line an just found something
like the patch number T105362-07."

"we had this problem before, but we installed a patch to fix that.
Try to install the recommended patches."

"Check the scsi cabling and connectors. You may have a
short circuit.

You may have to disable tagged command queueing or other features
with the new disk."

Thanks .
