IBM BladeCenter Deployment Guide
HS40 from the local media tray will work, but it is recommended that the lowres option be used for
the installation of AS2.1.
3. When booting from the remote floppy, the lowres (for RHAS2.1) or the nofb (for RHAS3.0) install
mode should function correctly. There have been intermittent instances of no keyboard response.
4. When loading Linux on an HS40, after unmounting the diskette, it is possible that EFI may replace the
“IBM Remote Disk” in the boot order, and the blade may boot into EFI instead of Linux. There is also
a problem referenced in RETAIN tip H1822293 that results in the HS40 boot order being reordered.
(http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-56325) If this occurs, follow the steps
shown on page 17 to reorder the boot sequence.
5. When a blade boots and the media tray is assigned to during boot up, the floppy drive in the media
tray is assigned as (in this example) /dev/sdc. However, since there is no diskette in the drive, we see
the following errors (beginning at READ CAPACITY FAILED):

Now, that wouldn't be the end of the world, necessarily, However, ANYTIME the KVM is switched on
the Bladecenter to/from that blade, the USB "stuff" (KVM and media tray) get re-hotplugged, for lack
of a better term, and the sdc errors are generated. They occur even after switch the media tray owner
to a different blade. The result is too many spurious errors which is making the internal support team
cranky.
Modification 1: Do not boot blade with media tray assigned in order to avoid errors when
someone takes the media tray away AND when the floppy drive is empty. NOTE: "alias floppy
off" should be added to modules.conf to avoid floppy drive errors when media tray not assigned
on boot.
