Hi all,

I know, I know this is trivial question.

I have tried to mount new hot swap scsi drive in IBM xSeries 226.

I have put new drive to the pocket and tried to list all new drives using

#fdisk -l

I cannot see that drive.

How to mount this drive ?

Should be something like /dev/sdc . In this server I have 3 drives (include this which should be mount). I have also restarted server. Doesnt help.


help

Looking at your out put I do not see sdc drive also. I see sda and sdb but not the third sdc. type cfdisk /dev/sdc and if nothing try fdisk /dev/sdc. one make sure the light is on for that drive. if that does not do it it is a bios problem. bios must read it then linux will see it. since it is a server and you need it up and running. put the drive in and then type as root dmesg. this will show what hardware is being loaded.and errors
if fdisk finds it then format it and use it. then it becomes sdc1. then make sure your /etc/fstab is setup to use a hot swap. that means if you pull a drive it reads the /proc and unloads the slot when loading it a drive it will load it to that slot.
so look at your /etc/fstab/ file. and edit it as needed.
and of course your actuall questionmount /dev/sdc1 this will read your /etc/fstab/ file and also your /etc/mtab file to see if it is loaded in the /proc good luck.
Also clean wiped drives are blank bios reads it but linux needs a formated file system to load the drivers for it. That is why cfdisk or fdisk must be run.
Good luck.
