The need for windows sharing..
A few days ago, I wanted to do a Oracle 12i installation on a x86 linux distribution using virtualbox. The media was available on an external hard disk, but I thought that instead of copying the 30+ G of media on unix virtual machine, why not just make it shared between [...]

A special need..
Those of you who have a need for exposing iscsi targets to other machines for discovery, but who do not want to invest in an external USB hard disk OR who do not want to have a USB external hard disk connected to a desktop 24×7, there is a better way of [...]

Preface
After playing around with some open source technologies like virtualbox and openfiler, we are finally at a point when it is possible to create your own network lab of Oracle 10gR2 RAC cluster and ASM database using iscsi targets in an external hard disk drive. The last time I checked, USB 2.0 hard disk drives [...]

A common problem…
If you are using openfiler, at some point of time, you are bound to reboot the openfiler OS/machine. After the reboot, a common problem is that openfiler forgets or loses the logical volume/volume group information.
So, as a workaround, you need to issue the following commands:
################################
# to discover the volume groups
################################
# vgscan [...]
