Is there a disk that behaves like SDA?
I examined the systems thoroughly and found the ILOM disk, a separate disk entirely that behaved like sda during the build process only. After I partitioned it (a few sentences down), the OS saw the raid that was presented from the hardware as /dev/sda and the ILOM was not visible to the OS (nor should it be).
How to make disk / dev / sda always-red hat?
It might be good for you to either use LVM, UUIDs or labels when making your partitions with your kickstart, so that your /etc/fstab will not have bare devices but either an LVM path, UUID or Label… see below…
Is the 300GB SDB the same as the SDA?
The Oracle Inc. graphical bios interface showed the mirrored 300gb drives as sdb, however, when I did the kickstart, the file had sdb, but later it registered as sda after the build!! – only after I successfully partitioned it. Where I work, we don’t always have control over what servers are purchased.
