[Linux-cluster] multipath devices and Conga storage tab

[brem belguebli]

Hello Arturo,
indeed Conga doesn't seem to summarize all the /dev/sd devices to
their belonging mpath one.
A potential side effect of this being  if you have an important number
of /dev/sd devices conga will timeout without showing you any result.

I personnaly gave up using conga.

About HP-DM, there is a OS's shipped solution (on which relies HP-DM!)
called device-mapper-multipath, there's no necessity to use the HP
one.

All went good, the cluster is up, but when going to the "storage" tab, I saw 8 devices (sda, sdb...sdh). This is caused of course by having two HBA in every node (there is another 4th node that is going to access another volume on the MSA).
