From 404d9a900b5bc83a3780ec337ca6fdcb04b766c0 Mon Sep 17 00:00:00 2001 From: Mark Haverkamp Date: Wed, 10 May 2006 09:12:48 -0700 Subject: [SCSI] aacraid: adjustable timeouts Received From Mark Salyzyn Add the ability to adjust for unusual corner case failures. Both of these additional module parameters deal with embedded, non-intel or complicated system scenarios. Aif_timeout can be increased past the default 2 minute timeout to drop application registrations when a system has an unusually high event load resulting from continuing management requests, or simultaneous builds, or sluggish user space as a result of system load. Startup_timeout can be increased past the default 3 minute timeout to drop an adapter initialization for systems that have a very large number of targets, or slow to spin-up targets, or a complicated set of array configurations that extend the time for the firmware to declare that it is operational. This timeout would only have an affect on non-intel based systems, as the (more patient) BIOS would generally be where the startup delay would be dealt with.
