Bug Description

Cisco M-series is a diskless server. Cisco open source snic driver is required at the install time to locate and mount the remote LUN in order for the installer to complete the OS installation.

snic-dkms package has been build and made available in https://launchpad.net/~cisco-ucs-team/+archive/ubuntu/snic-stable

MAAS 1.7.5+bzr3369-0ubuntu1~trusty1 can successfully install this server with this drivers.yaml: http://pastebin.ubuntu.com/11801974/

Install.log: http://pastebin.ubuntu.com/11801972/
Note a workaround (backup /tmp and restore it) in the /etc/maas/preseeds/curtin_userdata is required due to bug 1464442.

Additional info:
snic is open source and is accepted to upstream kernel, target 4.2.

@Samantha,

A question from Jason on this one. Why does the snic driver need to blacklist ahci?

It was a copy and paste from the hpvsa driver. Not necessary since ahci is for SATA, and snic is for SCSI.

I used this drivers.yaml (http://pastebin.ubuntu.com/11875478/) which didn't have blacklist ahci in the snic section, and the system is provisioned successfully.
