Installing Oracle VM Server on an HP Smart Array (CCISS) fails to blacklist system disks (they are not included in the /etc/blacklisted.wwids file). Messages similar to the following are logged in the /var/log/messages file:

multipathd: /sbin/scsi_id exited with 1
last message repeated 3 times

Workaround: Configure multipathing to blacklist the CCISS system devices by adding a new line to the multipath.conf file:

# List of device names to discard as not multipath candidates
#
## IMPORTANT for OVS do not remove the black listed devices.
blacklist {
        devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st|nbd)[0-9]*"
        devnode "^hd[a-z][0-9]*"
        devnode "^etherd" 
+       devnode "^cciss!c[0-9]d[0-9]*"    <<====
        %include "/etc/blacklisted.wwids"
}
