From d8a571135aad527e5984c8094b7977c6914f2550 Mon Sep 17 00:00:00 2001 From: Mark Haverkamp Date: Wed, 1 Feb 2006 09:30:31 -0800 Subject: [SCSI] aacraid: reduce device probe warnings Received from Mark Salyzyn. This patch sets up some device quirks surrounding arrays to inform the scsi layer that various mode pages are not supported. This reduces the severity of the complaints that show up in the logs as the array devices are enumerated.

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.
