Heya,
I think you should just try an empty multipath.conf, only put the
blacklist in. The EMC CX needs pp_emc as prio callout for example. The
defaults within multipath should just work.
Also make sure your failovermode and arraycommpath are both set to 1. A
few hints are mentioned on
http://christophe.varoqui.free.fr/wiki/wakka.php?wiki=TestedEnvironments
Please fill in if you find something that's missing there.
Best regards,
Bernd Zeimetz

Hi all,
I am trying to setup our server so that we have fabric failover from
the san. However my file sytem comes up read-only when I pull a cable
for testing.
I am using the following:
SLES 10
multipath-tools-0.4.6-25.8
q-logic 2342 dual port hba
emc cx600 san
(4) McData DS-24 switches (2 for fabric a and 2 for fabric b)
/etc/multipath.conf has the following entries:
xen2:~ # grep -v "#" /etc/multipath.conf
defaults {
udev_dir /dev
polling_interval 10
selector "round-robin 0"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout /bin/true
failback immediate
}
devnode_blacklist {
device {
vendor SEAGATE
product ST973401LSUN72G
}
}
multipaths {
multipath {
wwid 360060160f06109004352b218eb51da11
alias capsprod
path_grouping_policy failover
path_checker readsector0
path_selector "round-robin 0"
failback immediate
}
}
Can someone point me in the right direction to get this resolved?
