How to add or remove specific drivers during the recovery using Custom Recovery Disk for Red Hat Enterprise Linux (RHEL) 6.2 As an example, according to instructions below, a RAID driver for HP Smart Array Controller B110i/B120i needs to be added manually during an installation of RHEL 6.2. In addition, an AHCI driver needs to be removed. Installation Instructions: HP Dynamic Smart Array SATA RAID Controller Driver for Red Hat Enterprise Linux 6 (AMD64/EM64T) Similarly during a recovery using Custom Recovery Disk, the RAID driver needs to be added manually and the AHCI driver needs to be removed. If the RAID driver is not added and the AHCI driver is not removed, the custom SRD detects the physical disks as not RAID but independence.
