Under some conditions associated with the unclean transition to kdump, the aacraid adapters will view the array as foreign and not export it to prevent access and data manipulation. The solution is to submit a commit configuration to export the devices since this is a expected behavior when transitioning to a kdump kernel. This patch adds the aacraid.reset_devices flag and when either this or the global reset_devices flag is set, ensures that a commit config is issued and extends the startup_timeout if it is set less than 5 minutes. This attached patch is against current scsi-misc-2.6 and was unit tested on RHEL5 and 2.6.22. This is a bugfix, so this patch needs to propagate quickly.

This patch adds the aacraid.reset_devices flag and when either this or the global reset_devices flag is set, ensures that a commit config is issued and extends the startup_timeout if it is set less than 5 minutes. IF you are satisfied with this, I will submit it to the scsi list.
