basic SAN setup

I put a Qlogic HBA inside a diskless Proliant dl360 g4 server, and the HBA connects to a EVA fibric switch which connects to some drive array.  The other administrator has setup a chunk of diskspace with LUN 1.  

I try to install win2k3 on this diskless server.   It recognizes the HBA driver I specified.  However, when it tried to access the diskspace, it pop up this message - the harddisk containing the partition or free space you choose has a logical unit number greater 0.  There your computer's startup program cannot gain access to the disk.  Setup cannot install windows on this disk.  

Anyone has any ideas how can this be resolved?

In the HBA BIOS you have to set the boot LUN to be the same as the LUN the storage is presented as. If you set it differently then you will get this error message. You also have to enable boot BIOS enabled of course, that's off by default as well as the boot LUN not being set.


tried those already.  But will double check.

Perhaps they have the host OS set wrong, can easily change it using CV EVA.

Please check the blocksize  in your stroage system . Try 512 bytes

Booting over the san is a very complicated process and does not always work well.

Most folks would recommend that you have the os installed on a local disk, and use the san disk for your data.

If you get it working, please let us know.

You're right there Arthur, especially with Windows. Install using SCSIport driver, patch OS to the hilt and then change to storport driver. What a load of messing about.

Andy, I'm not sure if you are being sarcastic or not.  

I just know that many folks never get their machines to boot from a san even when they follow the instructions to the letter.

No, I wasn't being sarcastic Arthur, it is sometimes hard to get boot from SAN to work.
