Hello,
I'm using Fedora Core 3, Kernel 2.6.12, with two Promise SATA Controllers.
One 4 port onboard Promise controller and one 2 port Promise PCIController.
The Kernel detects the PCI controller first and names the attached drive sda
and sdb.
The drives attached to the onboard controller are named sdc to sdf.
The current thinking is that the sdX names should be avoided, e.g., in
fstab, so that even if you add and remove drives the remaining partitions get mounted
in the same place.
The drives are not mounted.
Is it possible to change this behaviour so that the drives attached to the
onboard controller are recognised first?
Why do you care?
The machine performs disk dumps from one drive to x drives. The master-drive
must always be sda. The onboard controller is much faster then the pci controller
thus it should be used first.
The pci controller sounds broken, and software that insists that a
particular drive is always sda seems overly rigid. If you could use
more flexible names, you could create symbolic links, e.g.,
/dev/source -> /dev/sdX, /dev/target1 -> /dev/sdY, etc. (perhaps using
the S.M.A.R.T. info to track which drive ends up where).
