Hello.
I have IBM blade, which is connected to EMC Clarion disk storage (2 FC
adapters connected to 2 FC switches, so system sees 4 paths to storage).
One lun is provided to the system. The problem is that FreeBSD doesn't
boot randomly (at least 1 attempt from 5 boots is unsuccessful). The
blade stalls and I see only blank screen.
I've tried other operating systems - OpenIndiana b148 and Ubuntu 10.10 -
each of them has booted perfectly 10 times without any issues.
I don't see any messages from boot1 stage and system is logged in to EMC
storage with only one path. When the system boots successfully, I can
see on EMC Clarion that it is connected with all paths. I've tried to
use boot0 from CURRENT - results are the same (boot fails randomly).
How can I debug this issue?
I have several FreeBSD servers with the same configuration which boot
perfectly. I tried different tricks to to achieve normal boot and all of
them worked randomly (or didn't work): some bios and FC adapter
settings, labeling all 4.2BSD partitions as unused and so on.
This time I noticed the following: if I leave my system stalling with
blank screen for ten minutes or more, it boots successfully... Does
someone have any ideas?
