How to manage a DS4700 logical drive on an IBM HS21 Blade

Posted on 2009-04-10
Last Modified: 2013-11-14
Hello Everybody,
I have a HS21 Blade connected to a DS4700.
Each FC port on the Blade is connected to a Brocade SAN Switch (via 2 chassis 20 ports Brocade FC Switches)
All the connections seem to be ok, but in Disk Management Console on the Blade (Windows 2003 Server x64) i can see 4 Disks (see attached screenshot).
My question is: How do I manage the logical drive on the Blade?
The Blade is connected redudantly to the DS4700, but i have no failover.
Thank you!

So you are seeing each volume on the DS4700 four times, right?

OK thats probably because windows can see four seperate paths to the LUN. The single HBA in your server can see all 4 ports of the DS4700 and Windows assumes these are seperate volumes.

Either use IBM's fail-over software to manage the paths or the LUN masking features on the DS4700 (partitioning).

To which particular IBM software are your reffering? SAN Surfer says that the HBA drivers don`t suport failover. I would appreciate if you can be more specific.
Thank you!

The solution was to install Subsystem Device Driver DSM based on MPIO drivers for Microsoft.
