From 28c1741736ff3f5069b1bff906d6c1574ddcd2f6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Klaus=20K=C3=A4mpf?= Date: Fri, 19 Jan 2024 01:55:38 +0100 Subject: [PATCH] Add ModeSense page 0x25 (DEC special function control page) (#1412) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add ModeSense page 0x25 (DECSpecialFunctionControlPage) VAXServer 3100 (CPU KA41-E) console firmware issues ModeSense(6) page 0x25 when probing for disks. A disk won't be recognized if this returns an error. The DEC SCSI specification[1], section 8.5 documents this page.
