Waiting for device to appear...

Hi,

I have the following problem with SLES 11 SP4 on an IBM System x3650 M4
(ServeRAID M5110e 3.24):

Booting stops while trying to mount the root device, exits to shell, then if
I simply exit the shell the device mounts successfully and the boot process
continues successfully:

Setup multipath devices: ok.

Any idea what’s the cause of the problem?

Thanks,

Hi Mirko,

sounds like some timing issue. You might want to start in debug mode (i.e. by adding kernel parameter “linuxrc=trace”), so that you get more output from the setup scripts.

Hi Jens,

I tried this - but wasn’t successfull. With this kernel parameter added the
system never booted, but endlessly produces udev messages to the screen. I’m
not familiar with udev, and it was way too much messages, so I don’t know if
they made any sense or indicated errors…

There are some factors with this machine (IBM x3650 M4) which make me feel
slightly overcharged…

  • it’s my first and only UEFI system
  • bootmanager is ELILO not GRUB
  • it has many disks: 2 RAID internal controller, 5 RAID1 arrays
  • 12 multipath devices on a IBM Storwize (SAS)

Probably I missed some important setting somewhere… (?)

Thanks,
Mirko

this might be a good reason to ask for SUSE support by opening a service request - do you have an according support contract?
