Did you try to see if the the MSA1000 is detected by BIOS when the server boots.  After the power to the system has been restored, press the Esc key to get to the Boot PROM prompt where Boot_Admin> is offered. At the Boot_Admin> prompt, type search:

Boot_Admin> search [Enter]

This will list the scsi disks

or else check this log file for SCSI devices detected


or try this

# /usr/sbin/ioscan -C disk

For further details you can refer to this article which talks about the above in detail

Perhaps the PSU for the 2/8 SAN switch (which is the MSA1000 chassis) is faulty.

I would connect the serial cable to the embedded SAN switch, 9600,8,n,1,n and login as admin (return for password so it isn't changed) type ipAddrSet and change it from  to a usable value and then connect to it with a web browser. (or you can telnet to to change the IP address if you want as long as you set your server network up for this temporarily)

Then on the web page select fabric manager zoning tool (bottom of left hand pane) and then you should see the WWID of the crossroads controller and of your HBAs. This will verify basic connectivity.

Can you experiment by plugging into the SAN switch in the working rack to test or i it in production? shouldn't cause a problem if it is zoned but could upset the SAN if not.
