** Deprecated - Cisco UCS Python SDK - Deprecated** - Page 3

Note: Due to the changes in the naming convention of the APIs in the SDK release 0.7.1, scripts written using SDK release 0.6.x need to be modified to make it work with SDK release 0.7.1. Also this version is not compatible with IMC Plugin 0.9.1 for Nagios.

With Python version 2.7.9 and above, python embedded the certificate validation.

In case of any issues with ssl protocol or certificate validation issue, you can run the below method before importing UcsSdk as a workaround.

def sslWorkaround():

isVerifyCertificate = False

if not sys.version_info < (2, 6):

from functools import partial

import ssl

ssl.wrap_socket = partial(ssl.wrap_socket, ssl_version=ssl.PROTOCOL_TLSv1)

if not sys.version_info < (2, 7, 9) and not isVerifyCertificate:

ssl._create_default_https_context = ssl._create_unverified_context

The workaround is working !

Thanks a lot Rahul,

Kind regards

I have below code:

from UcsSdk import *

from UcsSdk.WatchUcsGui import ConvertToPython

ucsm_ip = 'x.x.x.x'

user = 'admin'

password = 'xxxxxx'

if __name__ == "__main__":

try:

handle = UcsHandle()

handle.Login(ucsm_ip, user, password)

ConvertToPython()

handle.Logout()

except Exception, err:

print "Exception:",str(err)

import traceback,sys

print '-'*60

traceback.print_exc(file=sys.stdout)

print '-'*60

it return error :

Traceback (most recent call last):

File "test.py", line 10, in <module>

ConvertToPython()

File "/usr/lib/python2.6/site-packages/UcsSdk/WatchUcsGui.py", line 1223, in ConvertToPython

lastUpdatedFile = files[0]

IndexError: list index out of range

what's wrong here??

akalambu@cisco.com · ‎09-17-2015

am able to use the ConvertToPython for most APIs

But when i create a service profile template that results in List Index out of range and the below exception.

Traceback (most recent call last):

File "ucs_main.py", line 8, in <module>

Any thoughts?

robimath · ‎10-20-2015

IS there a git location from which i can download the existing scripts using the SDK ?

tocao · ‎11-04-2015

If you can give us some simple examples,that would be great.

like how to list all the severs, all the hbas, etc.

Can you tell me how to do that? Thanks.

robimath · ‎11-09-2015

Is there any plans to add os login handles to SDK ?

How do I save the value of a given attribute of an object?

I have read a ComputeBlade object with

uBlade = u.GetManagedObject(None, ComputeBlade.ClassId(), {ComputeBlade.SERIAL:thisSerial})

I can print the contents of my uBlade Object with WriteObject(uBlade), and can see, that its attribute "AssignedToDn" has value "org-root/org-VmWare/ls-VmWareSP01".

I want to save the value of this attribute to use it to get the Service Profile with this Dn.

Normally in Python, this should be done with

myAssignedToDn = uBlade.AssignedToDn or

myAssignedToDn = getattr(uBlade, 'AssignedToDn')

However this yields the error "AttributeError: 'list' object has no attribute 'AssignedToDn'"

(I tried all combinations of Upper and Lower Case for attribute "Ucs" with same result)

So how do I get the value of attribute "AssignedToDn" for my uBlade Object?

jmunk · ‎12-05-2015

Let me add, that I have imported everything from UCS SDK, and "assigned" type Compute Blade to the variable I use to store the UCS Blade MO:

from UcsSdk import *

uBlade = ComputeBlade()

I have been looking around in the User Guide for UCS Python code, where You extract an attribute from a MO Object, and cannot find any.

ragupta4 · ‎12-06-2015

Hi Jesper,

Which version of python sdk are you using?

Thanks

Rahul

jmunk · ‎12-06-2015

Got this answer from the Cisco BU through Cisco DK, which works!

> GetManagedObject() always returns a list of elements of the class listed in the request, even if there is only one element.

> This guarantees consistency in the return type, whether your request returns one or multiple elements.

>

> In your case, uBlade is thus a list of ComputeBlade, probably containing a single element, given that you seem to be filtering using a serial number.

>

> Try changing this line:

> uBlade = u.GetManagedObject(None, ComputeBlade.ClassId(),

> {ComputeBlade.SERIAL:thisSerial})

> To this :

> uBlade = u.GetManagedObject(None, ComputeBlade.ClassId(),

> {ComputeBlade.SERIAL:thisSerial})[0]

===============

Rahul (CC’ing Lars Granberg at Cisco DK, whom I have also asked this question)!

I am using 0.8.3 which is the newest on UCS communities (https://communities.cisco.com/docs/DOC-37174)

To my error description I will add, that when I do a “print uBlade” (where uBlade is my Class ComputeBlade Instance), I get “[<UcsSdk.UcsBase.ManagedObject instance at 0x0000000008A23848>]”, so my variable has class “ManagedObject”, but possibly not Class “ComputeBlade”

Below is my complete script for Your information

print uBlade

getattr(uBlade,'ComputeBlade.UCS')

#assocSpDn = uBlade.assignedToDn # <= This is where it fails. I show a number of commands here, which all fails

#assocSpDn = uBlade.ASSIGNED_TO_DN

assocSpDn = uBlade.Ucs

#assocSpDn = uBlade.UCS

#assocSpDn = uBlade.ucs

print "assocSpDn "+assocSpDn

updatedUBlade = u.SetManagedObject(uBlade, ComputeBlade.ClassId(), {ComputeBlade.USR_LBL:thisBladeUserLabel})

if updatedUBlade:

print "Blade after Update:"

WriteObject(updatedUBlade)

if uSp:

WriteObject(uSp)

else:

print "assocSp with Dn "assocSpDn" not found"

you can skip the Python certification validation :

handle.Login("x.x.x.x", username="xxxx", password="xxxx",noSsl=True, port=80, dumpXml=YesOrNo.TRUE)

Hi SDK Dev ,

When I try to get the MO’s using the OutCOnfigs.GetChild() attribute on the ConfigResolveDn instance it gives attribute error .

AttributeError: ExternalMethod instance has no attribute 'OutConfigs'

The same works for ConfigResolveChildren or ConfigResolveClass . Can you help ?

Thanks

Robin

My code:

crc = handle.ConfigResolveDn(parentDn, YesOrNo.TRUE,True)

if (crc.errorCode == 0):

for child in crc.OutConfigs.GetChild():

bootorder = child.Order

boottype = child.Type

Output :

Any ideas on when the next version of the Python SDK will be released?

arusrini · ‎03-18-2016

Amir,

The next version of theUCSM SDK is already out and is here: Cisco Ucs Python SDK - ucsmsdk (0.9.0.0)
