        Hello all,

I migrated my server from DevFS to udev. The reason for this migration was plan
to connect this server to IBM ESS 2105 Shark SAN storage over multipath tools
from Christophe Varoqui. Everything was OK up to upgrade to udev 0.5.20. I was
in trouble to bring up my server after upgrading to this version. I randomly
miss symbolic links for my local SCSI disk in /dev after reboot. Normally I have
these symbolic links in /dev:

sda -> scsi/host0/bus0/target0/lun0/disc
sda1 -> scsi/host0/bus0/target0/lun0/part1
sda2 -> scsi/host0/bus0/target0/lun0/part2
sda3 -> scsi/host0/bus0/target0/lun0/part3
sda4 -> scsi/host0/bus0/target0/lun0/part4
sda5 -> scsi/host0/bus0/target0/lun0/part5
sda6 -> scsi/host0/bus0/target0/lun0/part6
sda7 -> scsi/host0/bus0/target0/lun0/part7
sda8 -> scsi/host0/bus0/target0/lun0/part8
sda9 -> scsi/host0/bus0/target0/lun0/part9


But sometimes (after reboot) I miss some of these links. For example: sda2, 
sda6, and etc (periodically only one symbolic link is missing). Sometime I
found all symbolic links. In any case I have all nodes in the subdirectory
scsi/host0/bus0/target0/lun0. But existence of symbolic links to these
devices is unpredictable. I am not sure if it is problem of udev or hotplug.
Do you have any idea what is wrong? There are no errors on system logs.
Many thanks in advance.

Best regards,

Marek

There was never such a version number for udev. What does:
  udevinfo -V

print?

What does:
  udevinfo -q all -p /block/sda2
  
print - "sda2" replaced whith the device name you miss the symlink for?
