actually login on the storage servers at least once

    grep node.session.auth.password /etc/iscsi/iscsid.conf

You might also need to actually login to the SAN. First make sure you

can see the SAN controllers on the network, with, for example, `chi-san-01`:

    iscsiadm -m discovery -t st -p 172.30.130.22

Then you need to login on all of those targets:

    iscsiadm -m node -T iqn.1984-05.com.dell:powervault.md3200i.6782bcb00063c6a5000000004ed6d655 --login

TODO: shouldn't this be done by Puppet?

Then you should see the devices in `lsblk` and `multipath -ll`, for

example, here's one disk on multiple controllers:

```

root@chi-node-08:~# multipath -ll

tb-build-03-srv (36782bcb00063c6a500000f88605b0aac) dm-6 DELL,MD32xxi
