From ddd474420a0b0dfeda38b6b5f83c7af751235cc3 Mon Sep 17 00:00:00 2001 From: Mike Miller Date: Tue, 13 Sep 2005 01:25:22 -0700 Subject: [PATCH] cciss: new disk register/deregister routines This patch removes a couple of functions dealing with configuration and replaces them with new functions. This implementation fixes some bugs associated with the ACUXE. It also allows a logical volume to be removed from the middle without deleting all volumes behind it. If a user has 5 logical volumes and decides he wants to reconfigure volume number 3, he can now do that without removing volumes 4 & 5 first. This code has been tested in our labs against all application software.
