I am creating a cloning script to automate a minimalistic installation of Cent OS 5.5 on about 100 workstations of various hardware and age (2-10 years). The workstations are all either IDE or SATA.
I am currently developing the script and testing it on VMs (ESXi 4) with virtual IDE disks. In the initrd I have commented out scsi_mod.ko, sd_mod.ko & scsi_transport_spi.ko, and it seems to work just fine for booting a VM that uses an IDE disk. The problem is that I don't have easy access to the physical workstations and there are no virtual SATA disks for ESXi, so I cannot test with SATA disks.
Are the above SCSI modules needed on a workstation that only has a SATA disk? Are any SCSI modules needed for SATA disks (with a stock CentOS 5.5 kernel)?
