From 32d29776f8fe8293f7c5273624ec8fbd2b936bfa Mon Sep 17 00:00:00 2001 From: "brking@us.ibm.com" Date: Tue, 1 Nov 2005 17:02:01 -0600 Subject: [SCSI] ipr: Module parm to disable RAID 0 auto create Some ipr adapters will automatically create single device RAID 0 arrays for all unconfigured RAID capable devices found at adapter initialization time. This patch adds a module parameter to disable this behavior.
