Hi all,

I'm experiencing problems trying to set up a multipathd config with
a EMC Clariion CX-4 Storage.

It seems that the CX4 is actually active/passive regarding SPs. My
server  has QLogic Fiber Cards. My multipath-tools version is 0.4.8.

Here is my multipath.conf :

##

## This is a template multipath-tools configuration file

## Uncomment the lines relevent to your environment

##

defaults {

                 user_friendly_names   yes

}

blacklist {

                 #devnode "*"

                 devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"

                 devnode "^hd[a-z][[0-9]*]"

                 devnode "^cciss!c[0-9]d[0-9]*[p[0-9]*]"

}

devices {

                 device {

                                vendor "DGC "

                                product "*"

That is wrong. The configuration file doesn't allow for regular expressions or wildcards. Please use the correct name ('RAID 5') here.
And 'directio' is most certainly wrong here.

What's wrong with the default setting? It should work out of the box without configuration file at all ...

Cheers,

Hannes
