I have Blade servers booting off DS4700 arrays. I'm sure the procedure is the same for DS4800s.
Make sure you do the following: 1. Enable the HBA cards. Press F-1 while the server boots up to get into BIOS. 2. Configure the FC HBAs on the server after above step is done. (Ctrl-Q in my case for QLogic HBAs) 3. Create the fiber zones. (I use QLogic Sansurfer app for this step) 4. Define the host or hostgroup from the Storage Manager app. 5. IF you have multiple FC paths from the server to the storage, enable only the path you want to make primary. 6. Boot from CD/DVD and type "boot text mpath" Once you get to the stage where you need to select device to install OS, make sure to select /dev/mapper/XXX. Following is the explicit warning from RedHat docs: WARNING: Any devices of the form /dev/dm-n are for internal use only and should never be used. 7. Once OS is installed and server rebooted successfully, you can re-enable your other FC paths to the storage array and start testing your fail-over scenarios. HTH. Redhat on-line docs are very comprehensive. > On Thu, Feb 18, 2010 at 5:15 PM, madunix <[email protected]> wrote: >> Does anyone have directions on how to do boot from SAN DS4800 >> connceted to IBM bladecenter server >> unsing RHEL5.4 64bit...i have to build it for our production. any tips >> or links or documents ?...etc >> it would be really appreciated. > > Never got it to work with multi-path and don't think anyone has. > Single path works using both RDAC and native multipath. > > The threads you want are on IBM's site - sorry I don't have links.
