Cannot mount a new SCSI disk

[hotman_x]

I add a new SCSI disk to my server(Which runs Redhat Linux 9), and "cat /proc/scsi/scsi" shows the correct information, but "fdisk -l" cannot list the new disk.

Hii hotman_x,
Welcome to Linux Forums. Sometimes linux wont detect attached harddisks. Though just check your attach harddisk has been detected by your distro

Code:

#dmesg |grep scsi

If it shows output its ok, nxt step now you need to create device nodes for the new disk.
The MAKEDEV command is used to create new device nodes.

Code:

#cd /dev
#MAKEDEV sdX /* Here X means your a, b or c depending how many number of Scsi Hdd you have though for i.e if attched Hdd is secondary Scsi you should put b */

Reboot your machine fdisk -l should show your attached HDD.

Wow ! I didn't know about Makedev command. Thanx a lot infoshirish. I am reading its manual right now.

[hotman_x]

There exists a disk file /dev/sdb, but it have not attached to any true disk. Can I still use "makedev /dev/sdb"?

I cannot access my server now. I'll try it later.
Thank you, infoshirish.

Post the output of fdisk -l and cat /proc/scsi/scsi here.

Post the output of fdisk -l and cat /proc/scsi/scsi here.

I'll post the output as quickly as possible. But I can't access my server now.

I'm sorry the MAKEDEV did not work.

Here the output:
