Severity: normal

Hi,

We have some servers (blade IBM HS21/HS22) with Boot On SAN on IBM DS4700 with
debian lenny amd64.
Very fine since some years. http://www.tchetch.net/wiki/debian/multipath_ibm_ds4000

Now, we want to upgrade to squeeze. The upgrade is fine but i get
multipath problem on the first stage (initrd) so i suppose there is
some problem for initrd an multipath on squeeze.
Finally the server boot (but very long time). I want to fix this behavior.

Is there somebody Boot On SAN with squeeze ?

Thank You

Guy Roussin
