Thanks for looking at this problem:
# cat /etc/multipath.conf
# Blacklist all devices by default. Remove this to enable multipathing
# on the default devices.

## This is a template multipath-tools configuration file
## Uncomment the lines relevent to your environment

defaults {
multipath_tool "/sbin/multipath -v0"
udev_dir /dev
polling_interval 10
default_selector "round-robin 0"
default_path_grouping_policy multibus
default_getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
default_prio_callout "/bin/true"
default_features "0"
rr_wmin_io 100
failback immediate
}
devnode_blacklist {
devnode "hd*"
devnode "fd*"
devnode "ram*"
devnode "md*"
}
devices {
device {
vendor "IBM "
product "2105 "
path_grouping_policy multibus
