Our storage system advises to use 256 heads. Changing MAX_HEADS in cfdisk.h
to a higher number lets us use cfdisk.
Even with the change, it is not possible to use cfdisk successfully on
disks that have more than 255 heads.
from /usr/include/linux/hdreg.h:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
Your change just means that we tell the kernel to use HEADS%256 :-(
Hi,
I don't see why my change has an effect (Note I meant to say 'edit
cfdisk.c'). I have successfully partitioned a lun.
I needed to change MAX_HEADS because cfdisk would start with the option
-h 256.
I see that in hdreg.h the unsigned char has an effect, but it is not
clear how that effects me...
Could explain a bit more?
Thanks
