Hello, Gurus
I'm doing POC for Customer trying to deploy SAP. Trying B440M2 2x VIC1280 boot directly from NetApp 3240 via FC.
Prepared 450GB lun 0 on FAS3240, mapped it OK. In UCS service profile for B440M2 created boot policy to boot from lun 0.
Installation GUI SLES 4 SAP 11 SP3 from ISO detected lun 0 fine, installation gone fine, but, when system goes to reboot from disk it won't boot
with just "grub hard disk error". UCSM 2.2.1(d).
Is it working config ? Or, smth should be done to make B440 boot SLES from lun 0 with OS just installed.
Rgds, Yuri

When your installation detects the lun, and installs ok, it means, that FC zoning, and lun mapping/masking is ok.
Boot fails: something might be wrong with your boot policy ?
Can you please post your boot policy ? and the vhba's of your SP ?
Btw.
- is this classical SAP or HANA ?
- did you check
This section describes how to install Red Hat Enterprise Linux (RHEL) or SUSE Linux Enterprise Server (SLES) on a bootable SAN LUN logical disk or RAID volume using Cisco UCS Manager GUI and the KVM Console.

Wdey, ur right ! Found wrong lun id in the boot policy (BP).
Was 0 in BP, 4 in NetApp.
What I did:
- Changed LUN id to 0 on NetApp.
- Correctly interpreted Steps 5 & 6 of http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/os-install-guides/linux/b_B-Series_Linux_Install.pdf
just adding boot:linux pci=nomsi mpath into Boot section at the bottom of SLES ISO graph starting screen.
- Executed installation
The server installed and booted off the NetApp Lun JUST FINE !
Thanks, Wdey
