How to work using two hard disks------------------------


hello sir,
we had connected a second hard disk to a machine.
The machine was earlier working with one hard disk( with Redhat 7 installed).We had installed a second hard disk(with Redhat 9).While booting the BIOS has detected both the hard disks. By default the system boots with the First hard disk.But after booting I am not able to see the second hard disk. I tried using the mount command. (i.e. mount /dev/hdb)
Even I tried putting the second hard disk details in /etc/fstab.But still I am not able to use second hard disk parallely.

thanks

Using mount /dev/hdb won't work. You'll need to use /dev/hdbX, where X is a partition number. You'll also need to specify a mount point, which must be an already existing directory, and possibly the filesystem type as well. Overall, you need something like:

mount -t filesystem-type /dev/hdbX /mount/point

thanks for replying sir,
Actually I had installed Redhat 9 on one hard disk using some other machine
earlier and
Now as per new requirement I had simply fixed that hard disk
to the PC already having one hard disk with Redhat 7.

By defualt my PC is booting with the First hard disk (Redhat 7)
which is running L-DAP service.

I want to make DHCP server using second hard disk(Redhat 9).
Is it possible to use both hard disk simultaneously with LDAP service
running on one hard disk and DHCP on second hard disk.
I mean to say If the system is booted using Redhat 7 .Then can DHCP and LDAP be run parallely.and how.


thanks sir

Hi Pal

You need to boot up on redhat 7.x and go to the grub and edit it and let in know that there are two hard drives on your system and it should pick up that their is another O/S on the other hard drive..!

Hi Pal,
Im sorry but its not possible to run two OS simultaneously on the same machine, thats just impossible! One way would be to use VmWare (Virtual Machines) but thats a different story. Or do you mean that you would like to use them one at the time? only one kernel can adress the hw at the time.
Why cant you just run these services (LDAP & DHCP) on the same machine?
