Hi,default_getuid_callout "/sbin/scsi_id -g -u -s /block/% n"remove too : the CX need a special flag passed to scsi_id if I remember ...this was mentioned in a thread about the EMC CX a few weeks ago. But I think there's also a working default setting for this in multipath (at least it works very well with the default settings here). Also check http://christophe.varoqui.free.fr/wiki/wakka.php?wiki=TestedEnvironments - I've mentioned the neccessary settings on the CX there.

defaults { multipath_tool "/sbin/multipath -v 0 -S" udev_dir /dev polling_interval 10 default_selector "round-robin 0" #default_path_grouping_policy failover default_path_grouping_policy multibus
CX300 is not a multibus-capable hardware. You should remove this directive and let the in-core defaults apply.
default_getuid_callout "/sbin/scsi_id -g -u -s /block/% n"
remove too : the CX need a special flag passed to scsi_id if I remember ...
#default_prio_callout "/bin/false" failback immediate }

Hi,
I have
upgraded from SLES9-SP2 to SLES9-SP3.
The purpose
was to fix some problems related to
OCFS2.
I have many
warnings (as you can see below) in my /var/log/messages
related to multipath (i think), indicating that the devices aren't
ready.
Maybe the
multipath.conf needs some extra
configuration (please see my multipath.conf).
The sdc and
sdd devices are disks out on the EMC.
Can anyone
help me with this problem ?
