Hello.
I am using multipath-tools for sles9 sp3 ( multipath-tools-0.4.5-0.11 )
I am using the following configuration file
defaults {
polling_interval 5
udev_dir /dev
default_path_grouping_policy failover
rr_weight priorities
failback 10
}
devices {
device {
vendor "DotHill"
product "SANnet II FC"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
path_checker readsector0
path_selector "round-robin 0"
features "1 queue_if_no_path"
hardware_handler "0"
failback 10
}
}
i got 2 paths lined up to the same lun
pepper:~ # multipath -l

failover works great when i fail path 8:0
but when i reactivate it for some reason the deamon does not reinstate it.
only after i invoke
multipath -v 2
do i see the message
reinstate 8:0
which is odd since "multipath -v 2" is suppose to only print topology
can any one please help.
thanks.
