This week, I had an interesting situation at a Bay Area tech company. I was supervising the install of two HP servers running Windows 2008 R2, which were sharing a HP MSA drive array. The servers were connected to the MSA using fiber optic connectors. However, after bootup and configuration of the array, the drive appeared in the Windows drive manager twice and showed only 2 tb of the available 9 tb available for use. The remaining 7 tb were seen as unusable. Well, the HP technician was on the phone with their technician troubleshooting the wiring and the hardware. I left them alone because I figured that since it was their product, they would know best how to solve the problem.
