Hello Laurence,
I'm using the following multipath.conf file for the tests I run:
defaults {
user_friendly_names yes
queue_without_daemon no
}
blacklist {
device {
vendor "ATA"
product ".*"
}
}
devices {
device {
vendor "SCST_BIO|LIO-ORG"
product ".*"
features "3 queue_if_no_path pg_init_retries 50"
path_grouping_policy group_by_prio
path_selector "queue-length 0"
path_checker tur
}
}
blacklist_exceptions {
property ".*"
}
Bart.
