Tests performed on a backport to kernel version 2.6.18 of this driver with a
Linux initiator system:
- Verified that the kernel module ibmvstgt loads and initializes successfully
and also that the client connected after loading.
- Verified that virtual disks configured in scst_vdisk were discovered by
the client.
- Performed IO stress testing on the device.
- Performed basic I/O performance testing. With a RAM disk as target linear
direct I/O throughput was above 2 GB/s and a 4 KB random I/O test resulted
in more than 10000 IOPS (without any caching of DMA mappings in the target).
Both initiator and target were a dual core POWER6 LPAR.

- Verified that all virtual disks configured in scst_vdisk were discovered by
the client after rescanning the SCSI bus.
- Verified that after unloading and reloading ibmvstgt and after client
recovery that the initiator devices were functioning normally.
- Verified that after a client reboot ibmvscsic reconnected with the target
and that the target devices were again usable.
