From bb08f92ebd75704e07d69bb9d8ee234d1a500b98 Mon Sep 17 00:00:00 2001 From: Mark Haverkamp Date: Wed, 1 Feb 2006 09:30:44 -0800 Subject: [SCSI] aacraid: use no_uld_attach flag Received From Mark Salyzyn. In order to support user tools accessing the array components (SMART, Mode Page information, Cache page adjustments, WWN determination, Firmware updates etc), we take advantage of the no_uld_attach flag and deprecate the code that filters Inquiries to block the requests to array components. The quirk prevents the sd layer from attaching to the components. We also took the opportunity to balance the queue depths based on the total adapter queue depth to the array devices to reduce the chances of starvation.
