All these 20 disks are qcow2 formatted .. I have created these qcow2 format disks on the nfs mounted directory.
So different issue exists with parted -l also ..

ISST-KVM-UBUNTU:20 scsi disks in a VM, fisk -l doesnot list all the
disks available
Status in “dpkg” package in Ubuntu:

Bug description:
Classification the type of defect:
==================================
DEFECT :distro
TYPE OF DEFECT:Ubuntu 14.04
Description of the defect: [[ Guest VM does not list all scsi disks
in "fdisk -l" .
1. Installed the Ubuntu Guest with 20 scsi disks ( qcow2 formatted ,
5G each , These disks are present on the nfs mount )
# uname -a
Linux ubuntu 3.13.0-23-generic #45-Ubuntu SMP Fri Apr 4 06:58:01 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
# ppc64_cpu --smt
SMT is on
2. fdisk -l doesnt list all the disks .. It lists from sda till sdh (
8 disks) . whereas sdi till sdu arent listed. All the disks are
created on the nfs mount point.
root at ubuntu:/dev# fdisk -l
The number of cylinders for this disk is set to 20480.
This is larger than 1024, and may cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software form other OSs
(e.g., DOS FDISK, OS/2 FDISK)
