RAID 1 with IDE HDD

hello all,

i am new to the RAID installation and functioning. I have just configured RAID1 on my Redhat linux 8.0 machine. I am on a Intel 845 motherboad with 2GB of RAM and have used 2 160 GB IDE.

Both the HDD are connected to the same IDE cable as master and salve. but after reading the following information at misconfigured the RAID installation

"The failure of one drive on an IDE bus often causes the malfunctioning of the second device. This can be bane if you have two IDE drives of the same RAID set attached to the same cable."

here are the some more details ------------etc-raidtab----------- raiddev dev-md0 raid-level 1 nr-raid-disks 2 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device dev-hda3 raid-disk 0 device dev-hdb3 raid-disk 1 raiddev dev-md2 raid-level 1 nr-raid-disks 2 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device dev-hda1 raid-disk 0 device dev-hdb1 raid-disk 1 raiddev dev-md1 raid-level 1 nr-raid-disks 2 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device dev-hda2 raid-disk 0 device dev-hdb2 raid-disk 1

will the following changes to theetc-raidtab file and connection the exisitngdev-hdb (Primary Slave) asdev-hdc (Secondary Master) work, or i need to reinstall the whole machine ?
