==================================
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@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)
