scsi hard drives problems
Hi,
on Linux redhat server (6.2), i face a problem to make a copy of one scsi disk :/dev/sda to an other one /dev/sdd.
Due to a problem on the fisrt disk system disk ( the server has 3 scsi disks), on 8363MB each one, i have to change it , with an other of the same size, i want to make a whole copy disk with dd, and create a boot sector like this
dd if=/dev/sda of=/dev/sdd bs=512 count=101M
When i boot on the new system disk it's doesn't work , do you have any solution?
these are y partitions table on the two disks
root:/mnt : fdisk /dev/sdd
The number of cylinders for this disk is set to 1106.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
