Hi,
I have a RedHat 9 system running kernel 2.6.16... The system is attached to
3 x EMC FC4700 DOE's operating as simple JBODs....
Looking at /proc/scsi/scsi, I can clearly see all the devices are visable
(see below)
However, each time RedHat boots it assigns a different device to a different
hard drive... For example, one of my CLAR18 disks in Eclosure 3 Bay 3, ends
up at /dev/sde. When I reboot, that same drive, will all of a sudden become
/dev/sdm. Needless to say with the devices flying arround like this, it is
impossibly to create any array or use any of the devices...
I have no way to know that any device will have the same name after a
reboot... Is there any way to fix this??
Thanks,
Chris.
