Where I grew up, the myth of the jackalope was pervasive. I would see this creature stuffed hanging on the wall of my local hardware store. I was always on the look out for a true living jackalope. Needless to say, I never saw a single one except those hanging on the walls of some of the local shops. As I grew up, I concluded that some talented taxidermist who would take the skull of a jackrabbit and combine it with the antlers of a small deer or antelope to create the jackalope myth.

Creating a large file
When you wish to create a very large file for test purposes, try this command:
# dd if=/dev/zero bs=1024 count=2097152 of=./test.large.file
This wil create a file consisting of 2097152 blocks of 1024 bytes, which is 2GB. You can change the count value to anything you like.

It appears that FOR loops with number ranges defined, using the format {1..10} do not work in an IBM VIO server environment even from the oem_setup_env shell which IBM prefers you stay away from in the first place. However, when you are dealing with mapping large numbers of disks to virtual SCSI hosts, you need a bit of a helping hand. For example, IBM i V6R1 and higher allow you to use non-520 Byte storage devices for disk allocation as long as the disks are presented as VSCSI through a VIO server which then formats the disks as 520 Byte disks.
