Cisco UCS driver not able to get boot device when the boot device is set to other than pxe

[Pradeep Varadarajulu]

Steps to reproduce:
================

1. Enroll a UCS node.

2. By default the boot device is set to pxe.

stack@ir-cont:~/devstack$ ironic node-get-boot-device f0655b17-5327-432a-ae8d-f76cdff5c98b
+-------------+-------+
| Property | Value |
+-------------+-------+
| boot_device | pxe |
| persistent | None |
+-------------+-------+

3. Change the boot device to disk or cdrom
stack@ir-cont:~/devstack$ ironic node-set-boot-device f0655b17-5327-432a-ae8d-f76cdff5c98b disk
stack@ir-cont:~/devstack$ ironic node-set-boot-device f0655b17-5327-432a-ae8d-f76cdff5c98b cdrom

4. Get the boot device for the ironic node.
stack@ir-cont:~/devstack$ ironic node-get-boot-device f0655b17-5327-432a-ae8d-f76cdff5c98b
u'\'disk\'\n (HTTP 500)
stack@ir-cont:~/devstack$ ironic node-get-boot-device f0655b17-5327-432a-ae8d-f76cdff5c98b
u'\'cdrom\'\n (HTTP 500)

Fix proposed to branch: master

[Lucas Alvares Gomes (lucasagomes)]

This only affects the version 0.8.2.2 of the library right?

The documentation we have upstream is saying that the required version is 0.8.1.9 [1] (its pinned on this version, it's not the minimal required version).

[Gopi Krishna S (saripurigopi)]

Yes Lucas, this was due to change in the UcsSdk v0.8.2.2. will update the prerequisites.

    UCS: node-get-boot-device is failing for Cisco servers

    The UCS to Ironic key mapping for supported boot devices was changed
    in UcsSdk v0.8.2.2. As a result of that, UCS drivers are failing while
    looking at the UCS to Ironic mapping devices dict.

    This change would address this problem.
