6.105 (x86 Only) Blacklisting of System Disks for Multipathing Fails on HP Smart Array (CCISS) Disk Devices

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"

This workaround is not required for HP Smart Array disks backed by the HPSA module.
