Hello, when we try to create a new volume in openstack, everything is alright, but when we try to create an instance with cinder from image, the mesage below appears.

in ssh.py, _run_ssh.py will fail if the ssh session has been closed, which can happen on a heavily loaded environment. In our patched version of the 3parclient, I moved my retries to 2 and reinitialize ssh if the session is dead, like this: (see next entrry)

The following exception occurs when attempting to attach a volume to a 3PAR that has VLUNs with no hostnames. This could happen if volume or volume set were exported to direct ports. The client's getHostVluns needs to take this into account.

I'm currently working with a legacy code that expects LUN==0, but I cannot make 3PAR storage create such VLUN mapping from WSAPI.

I believe this is not a 3PAR box limitation, as I CAN make one from CLI:

cli% createhost testhost
Setting default host persona 2 (Generic-ALUA)
cli% createvv default testvv 1G
cli% createvlun testvv 0 testhost
Warning: Host testhost has no active paths.  Template may be created but no active VLUNs will be created.
cli% showvlun -v testvv
Active VLUNs
no vluns listed

VLUN Templates
Lun VVName HostName -Host_WWN/iSCSI_Name- Port Type
  0 testvv testhost ----------------       --- host
---------------------------------------------------
  1 total

As you can see in the result, VLUN mapping can be created with Lun==0 from CLI.

OTOH, here's what happens from WSAPI:

In [3]: cl.createVolume("testvv", "default", 1024)
In [4]: cl.createHost("testhost")
In [9]: cl.createVLUN("testvv", 0, "testhost")

So WSAPI thinks "lun" is missing when lun==0. And when I change it to 1, it passes:

In [10]: cl.createVLUN("testvv", 1, "testhost")
Out[10]: 'testvv,1,testhost'

Is there any limitation in creating VLUN with LUN==0, or is this a WSAPI issue?

on pypi there are releases for 4.2.4 and 4.2.5 but the corresponding git tags are not here.

Curl command fails on v3

Against v1, api running on the array which supports v3/v1 , the same payload works

What we have found further is , the password text has to be send in a JSON string array format

There was chaos in calling exceptions. request() in http.py is using requests.exceptions.x which are not being called in inheritance order. This causes failure in exception raise.

Hi Team,
Is there any command or any way to get the recent 3-par storage alerts Via python-3parclient ?

Thanks
Sunny

Detach volume issue a series of rest commands, one of the delete request is missing WSAPI SessionKey which results in 403 invalid session key from WSAPI and leaves the session dangling.

When the FC Driver is initialized on an 3PAR array where the iscsi ports are offline or not there, we get the following error on HPE 3PAR Docker Volume plugin error.

MountVolume.SetUp failed for volume "sc1-90ad0972-9ce0-11e9-85b5-566f4fb90000" : mount command failed, status: Failure, reason: HPE Docker Volume Plugin Mount Failed: ('Initialize Connection Failed: connection info retrieval failed, error is: ', 'pop from empty list')

When a volume is in use, it cannot be deleted and an HTTPConflict excpetion is raised. API Documentation should add this along with the other exceptions.

body variable is not defined when useHttpDelete is set to false and removeFromTarget is set to true.
Line https://github.com/hpe-storage/python-3parclient/blob/master/hpe3parclient/client.py#L3748 will give error.

In _set_key_value(), the following code utilizes only first entry of VFS and ignores other 3 possible VFS entries (if set):

        elif key == 'vfsip' and value:
            # Expand the sub-fsips like in getfsip.
            interface = self.gettpdinterface()['getfsipInd']
            dictionary[key] = self._create_member(interface, value[0])

The WSAPI version on primera is now 1.10.0. Which since the 'minimum' version is 1.5.0, means that the code thinks the minimum version is not met and breaks any attempt at a creation of a compressed lun. Please fix ASAP

Can you please tell me what am I doing wrong?

Contrary to what the docstring says, debug logs cannot be disabled:

    def set_debug_flag(self, flag):
       """
       This turns on/off http request/response debugging output to console

And if we enable debug logs on the client on initialization via the debug parameter then SSH logs will not be enabled.

Current documentation for deleteVLUN needs to be corrected.

It is documented to be a str formatted with node:slot:port, but the code is expecting a dictionary with keys "node", "slot", "cardPort"

The client is ignoring errors returned by a 3Par array when requested manila actions cannot be performed. It's necessary to set "hp3par_debug = True" in manila.conf to see the errors that 3Par is returning.

Customer ran into issue with default SSL lib using in httplib2, it's a known defect for along time and doesn't look to be fixed soon, the customer had to change httplib2 to use ssl.PROTOCOL_TLSv1.

We should use requests lib instead of httplib2, some of openstack has already moved to this version.
The customer has requests==2.3.0 in there envrionment

I'm trying to embed JSON-encoded string (for operational reasons) in a comment field, and API call is failing with a HTTP 500 error.

Here is a CLI example which passes without an error:

cli% createhostset -comment {["some", "json", "data"]} fooset
cli% showhostset -d fooset
Id Name   Members Comment
46 fooset --      ["some", "json", "data"]

At this point, I can successfully read above hostset info over WSAPI:

In [28]: cl.getHostSets()
Out[28]:
{'members': [{'comment': '["some", "json", "data"]',
   'id': 47,
   'name': 'fooset'}],
 'total': 1}

However, when I try to do the same thing (= create a hostset over WSAPI), it fails.
It seems either "[" or "]" is causing this, but any printable chracters up to 255 characters should be supported as stated in the documentation (CLI reference, createhostset command).

In [32]: data = '["some", "json", "data"]'
In [33]: cl.createHostSet("fooset", comment=data)

HTTPInternalServerError: Internal Server Error (HTTP 500) 1 - internal server error

As the error is HTTP 500, could this be an issue with the WSAPI server running on a 3PAR box?

There's an bad indentation in setQOSRule at line :

            cmd.append('vvset:' + set_name)

If only max_io is defined, the "cmd" generated looks like
setqos -io 12345
and is incorrectly interpreted by 3par array.

def setQOSRule(self, set_name, max_io=None, max_bw=None):
        cmd = ['setqos']
        if max_io is not None:
            cmd.extend(['-io', '%s' % max_io])
        if max_bw is not None:
            cmd.extend(['-bw', '%sM' % max_bw])
            cmd.append('vvset:' + set_name)
        result = self._run(cmd)

Is there a way to encrypt the user and password for authentication?

Hi

i might be dumb, but I cant find a way to promote a snapshot using this API. I can do it manually in the web interface of the 3par, but I miss the automation here.

Is it a missing function in the API, or did I overlook something?

Greetings

When creating vLUN using autoLUN option an error is thrown:

hpe3parclient.exceptions.HTTPConflict: Conflict (HTTP 409) 99 - invalid operation: LUN number and persona capability conflict

This is caused in specific cases:

1. host persona VMware 11 is used
2. LUN IDs 0-255 are used.

Root cause is introduction of PE LUN for host persona VMware 11 (LUN ID). Since HPE didn't provide a fix yet for 3PAR OS, we would like to as for enhancement of 3PARclient code in following way for autoLUN option.

1step.
autoLun = True
lun=0
maxAutoLun=0

if receive error "Conflict (HTTP 409) 99 - invalid operation: LUN number and persona capability conflict" ignore error and continue 2step

2step.
autoLun = True
lun=257
maxAutoLun=0

thanks,
Miro

Please update to 4.2.5

We are looking to use openstack cinder for managing our 3PAR storage server(s).

While setting up a PoC environment I appear to be unable to setup peer-persistence. We are using SYNC mode for our volumes, and I am able to successfully create remoteCopyGroups and sync replicated volumes through cinder (and thus the 3parclient). I do not see any code in neither Cinder driver nor the 3parclient to support adding a new RCG to the list of groups enabled for Peer Persistence.

Is this functionality available in any way? Should we be solving this differently (i.e. some kind of default configuration on the 3PAR to have RCG's by default peer-persistent), or was this particular feature just not implemented? We can implement the feature in cinder if necessary, but I would prefer to be able to at least use the upstream 3parclient.

Thank you in advance for any feedback/pointers you can provide.

Hi

the code of findVolumeSet hardcodes to only return the first result of volumesets to which a volume is exported.
3Par allows to export to many vvsets and there are situations where this must be (say, VM live migration with VM storage on 3Par volumes, clustered filesystems, ...).

There should be a way to have all vvsets listed in which a volume exists.

When a user vlan tags iscsi ports on 3par systems this driver can't find the port information required to connect initiators and fails out. I've attached a file with the ouput of the showport and showport -iscsivlan commands from the 3par system I have under test and the cinder debug logs and error:

hp3par_client_error_iscsi_port_vlans.txt

I'm willing to write the update for this feature. I wanted to have some discussion around the way the owners would prefer to see it done. I see two options:

1. Add a self.ssh.run('showport -iscsivlan') to the getPorts() method, massage the output into an array of port objects similar to what it gets from the api call, and append it to the members key of that object. Or,

2. Add a hp3par_iscsi_vlans_enabled=true flag to cinder_override.conf and create tie-ins to getPorts() to only return the output of one command or the other.

I think I'd prefer 1 since it would let people use vlans without any extra work being done by the end user. I'm open to additional options as well.

Hello,

I had to disable the code below to use it because of Invalid 3PAR WS API. My systemVersion is 3.1.3.202

181 # try:
182 api_version = self.getWsApiVersion()
183 # except Exception:
184 # pass
185 # msg = ('Either, the 3PAR WS is not running or the'
186 # ' version of the WS is invalid.')
187 # raise exceptions.UnsupportedVersion(msg)
188
189 # Note the build contains major, minor, maintenance and build
190 # e.g. 30102422 is 3 01 02 422
191 # therefore all we need to compare is the build
192 # if (api_version is None or
193 # api_version['build'] < self.HP3PAR_WS_MIN_BUILD_VERSION):
194 # raise exceptions.UnsupportedVersion(
195 # 'Invalid 3PAR WS API, requires version, %s' %
196 # self.HP3PAR_WS_MIN_BUILD_VERSION_DESC)

getVLUN(volumeName) method receives a volume name as its unique parameter and is described in the API as

    Get information about a VLUN.

    :param volumeName: The volume name of the VLUN to find
    :returns: VLUN

This description seems to imply that a volume can only have one associated VLUN which frequently is not the case (a volume can be exported to one or several hosts or one or several hosts sets).
Indeed, in its implementation, this method gets the list of VLUNs matching the volumeName but only returns the first one (on purpose, as stated by the comment "Return the first VLUN found for the volume"):

Related note: as this library does not expose WSAPI's filtering support, the only current way to get an actual list of the VLUNs of a volume is to use getVLUNs() to get ALL the volumes and filter it client-side.

There seems to be a problem recently added to the hp3parclient package which is preventing an error message from being placed in the log. Instead of the intended message, we see a message about an exception being thrown.

Details follow:

This is the function that works. It is located in /usr/local/lib/python2.7/dist-packages/hp3parclient/client.py at around line 175. Git branch says this is Juno.

def init(self, api_url):
self.api_url = api_url
self.http = http.HTTPJSONRESTClient(self.api_url)
api_version = None
self.ssh = None
try:
api_version = self.getWsApiVersion()
except Exception:
msg = ('Either, the 3PAR WS is not running or the'
' version of the WS is invalid.')
raise exceptions.UnsupportedVersion(msg)

    # Note the build contains major, minor, maintenance and build
    # e.g. 30102422 is 3 01 02 422
    # therefore all we need to compare is the build
    if (api_version is None or
       api_version['build'] < self.HP3PAR_WS_MIN_BUILD_VERSION):
        raise exceptions.UnsupportedVersion(
            'Invalid 3PAR WS API, requires version, %s' %
            self.HP3PAR_WS_MIN_BUILD_VERSION_DESC)

This is the function that doesn’t, located in the same place. Git branch says this is master.

def __init__(self, api_url, debug=False):
    self.api_url = api_url
    self.http = http.HTTPJSONRESTClient(self.api_url)
    api_version = None
    self.ssh = None

    self.debug_rest(debug)

    try:
        api_version = self.getWsApiVersion()
    except Exception as ex:
        ex_desc = ex.get_description()
        if (ex_desc and "Unable to find the server at" in ex_desc or
                "Only absolute URIs are allowed" in ex_desc):
            raise exceptions.HTTPBadRequest(ex_desc)
        else:
            msg = ('Error: \'%s\' - Error communicating with the 3PAR WS. '
                   'Check proxy settings. If error persists, either the '
                   '3PAR WS is not running or the version of the WS is '
                   'not supported.') % ex_desc
            raise exceptions.UnsupportedVersion(msg)

    # Note the build contains major, minor, maintenance and build
    # e.g. 30102422 is 3 01 02 422
    # therefore all we need to compare is the build
    if (api_version is None or
       api_version['build'] < self.HP3PAR_WS_MIN_BUILD_VERSION):
        raise exceptions.UnsupportedVersion(
            'Invalid 3PAR WS API, requires version, %s' %
            self.HP3PAR_WS_MIN_BUILD_VERSION_DESC)

The line causing the error is the if statement within the except statement.

if (ex_desc and "Unable to find the server at" in ex_desc or
"Only absolute URIs are allowed" in ex_desc)

The problem seems to be that in order of operations, and is evaluated before or, so the second time python checks for a string in ex_desc, an exception is thrown because ex_desc is NoneType.

Hi,

I am using this library for communicating to the array over web-service/REST APIs.
in a case, when I try to get a volume for knowing its information, i'm not able to get the volume's details.
The data responded to me is "None"

Then I checked at array side & checked using CLI , the volume is present on the Array.

Can someone please let me know what could go wrong? this is really serious problem for me.

Hi there,

When I use client.deleteVolume(name=volume_name) I encountered below failure.
I tried to find the root cause and found that it was because I want to store the exception into a variable in the catch block and the exception's str throw an exception.

code snippet:

try:
	cl.deleteVolume(name=vv_name)
except Exception as e:
	message = "failed to remove virtual volume, name=%s, error=%s. " % (vv_name, e)

Traceback (most recent call last):

Uninstalling an old client : If the older HP3PARClient was installed on the system already it will need to be removed. Run the following command to remove it:
$ sudo pip uninstall hp3parclient

The correct package name
$ sudo pip uninstall python-3parclient

There is no application set adding for the volume in the python-3parclient. Any idea how to do the task in python?

Hi,
we have a python script that pulls volume capacity information from the 3Par arrays to be stored in InfluxDB. The script worked fine with the old hp3parclient on our 3par 7400s and 8450 until the 3par 8450 was upgraded to 3.3.1.460 (MU3)+P50 .
If I ran the script now, it returns values up until a point where it give this response:
Unable to get volume capacity
Internal Server Error (HTTP 500) 1 - internal server error

the actual call that fails (values in <> not shown for privacyreasons):
REQ: curl -i http://:8008/api/v1/volumes -X GET -H "Accept: application/json" -H "X-Hp3Par-Wsapi-Sessionkey: " -H "User-Agent: python-3parclient"

Anyone encountered this? Anything changed in that OS version that changes API behavior?

With the release of the new client, the following error message is constantly logged:

/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/connectionpool.py:768: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.
See: https://urllib3.readthedocs.org/en/latest/security.html
InsecureRequestWarning)

Currently there is now way to suppress this warning, making the log file bogged down with these messages. There should be a an override flag that allows you to willingly disabled these log messages.

Hi,

From WSAPI v1.5 you can query the internal System Reporter database.
Please add support for the SR commands to python-3parclient.

Thx,

Pete

Hi.

I'm now trying to develop software on top of hp3pardata API, and noticed it won't work with Python3.
Even the following simplest code fails with a TypeError:

#!/usr/bin/python
# -*- coding: utf-8 -*-
import hp3parclient
from hp3parclient.client import *
cl = HP3ParClient("http://172.16.4.161:8008/api/v1")

The root cause was that httplib2.request() method now returns a 'bytes' object instead of a 'string' due to a change in Python3 (I'm using Python 3.3). This broke JSON parser when 'bytes' object is passed.

Quick fix is to turn HTTP response body back into string as I posted in #11 .

We have proven there is no problem on the system. In the same time we executed the command in a different way, the output was always complete. The problem does not occur for 4-node systems.

Function getting the data:

def get_data_ssh(array, cmd_list, severity_rc):

    cl = ssh.HPE3PARSSHClient(array, username, password, conn_timeout=timeout_ssh)

    try:
        cl.open()

    except paramiko.ssh_exception.SSHException:
        print('CRITICAL: Login to {} via ssh failed '.format(array))
        print(os.linesep + 'Process runtime: ' + str(time.time() - start_time) + ' seconds')
        exit(severity_rc)

    data = cl.run(cmd_list)
    cl.close()
    return data

When an array has huge number of volume(s) the GET call takes lot of time to return the information. For which 3PAR has a solution to return the information in chunks. Just a thought that it will be great to have feature.

PS: I will be grateful if I can help in accomplishing this.

There's an "L" missing to "urllib" line 34

try:
# For Python 3.0 and later
from urlib.parse import quote

# Fall back to Python 2's urllib2

Looks like the ssh pool removal forgot something:

Once Debug is enabled each different exception should be returned in addition to 3PAR WS not running or WS is invalid

1. wrong IP
   a. RESP BODY:Unable to find the server at 99.99.99.999
2. No_proxy entry for array
   a. RESP BODY:(503, 'Service Unavailable')
3. bad uri format
   a. RESP BODY:Only absolute URIs are allowed. uri = bad/api

On slow SSH connections both parsers, default and multi-line, fail because the responses are somewhat different than what they expect:

• We don't get the initial stdin dump of the commands we've sent before the first prompt.
• We get empty prompts with no command, as if we had entered an additional enter key.

Fixing the default parser would be more complicated, but the multi-line one should be able to support these cases.
