Manually Switching Nexus1000v Active VSM to Standby

Use this procedure to manually switch an active VSM to standby in a dual supervisor system.
BEFORE YOU BEGIN
Before beginning this procedure, you must know or do the following:
•You are logged in to the active VSM CLI in EXEC mode.

•You have completed the steps in the “Verifying that a System is Ready for a Switchover” section, and have found the       system to be ready for a switchover.
•A switchover can only be performed when two VSMs are functioning in the switch.
•If the standby VSM is not in a stable state (ha-standby), then you cannot initiate a manual switchover. You will see the following error message:

Failed to switchover (standby not ready to takeover in vdc 1)

•Once you enter the system switchover command, you cannot start another switchover process on the same system until a stable standby VSM is available.

•If a switchover does not complete successfully within 28 seconds, the supervisors will reset.

•Any unsaved running configuration that was available at active VSM is still unsaved in the new active VSM. You can verify this unsaved running configuration using the show running-config diff command. Save that configuration, if needed, as you would do in the other VSM (by entering thecopy running-config startup-config command).

SUMMARY STEPS

1. system switchover

2. show running-config diff

3. copy running-config startup-config

EXAMPLES

This example shows how to switch an active VSM to the standby VSM and displays the output that appears on the standby VSM as it becomes the active VSM.

n1000v# system switchover

----------------------------

2009 Mar 31 04:21:56 n1000v %$ VDC-1 %$ %SYSMGR-2-HASWITCHOVER_PRE_START:  
This supervisor is becoming active (pre-start phase). 
2009 Mar 31 04:21:56 n1000v %$ VDC-1 %$ %SYSMGR-2-HASWITCHOVER_START:  
This supervisor is becoming active. 
2009 Mar 31 04:21:57 n1000v %$ VDC-1 %$ %SYSMGR-2-SWITCHOVER_OVER: Switchover completed. 
2009 Mar 31 04:22:03 n1000v %$ VDC-1 %$ %PLATFORM-2-MOD_REMOVE: Module 1 removed (Serial 
number )

This example shows how to display the difference between the running and startup configurations:

n1000v# show running-config diff

*** Startup-config

EMC networker nsrvadp_save: Unable to find the VM with VM name

Application information attribute VADP_VM_NAME for client “<xyz>” is set to “<xyz.gkhan.in>”.
Trying to connect to the VM using VM name ‘< xyz.gkhan.in >’.
80398:nsrvadp_save: Unable to find the VM with VM name: < xyz.gkhan.in>.
Temporary directory ‘c:\mnt\<xyz>’ for VADP deleted.

To Solve this issue you have to:

1- While configuring Client Backup Configuration use the Virtual  Machine Name from the computer properties as it is because Virtual  Machine name is case sensitive  .

2- In the application information attribute VADP_VM_NAME= virtual machine computer name

 Note That : VADP_VM_NAME is case-sensitive. For example, if the VM host name is upper-case 

(such as MBX1), the value of VADP_VM_NAME must be set to MBX1. Also, if the name entered for VADP_VM_NAME contains spaces, the name must be contained within quotation marks (for example, VADP_VM_NAME=”this is my machine”)

4- Under Extension option

User Extension will be same as what you have given in the Virtual Fax  and SIP Alias will be same as Extension number.

4- under Assigned DID /CID

Provide your DID number  and secret as what you have given in virtual fax.

5- Click Apply and save . and now open the Extension configuration of IAX what just you have created .

and change the Requirecalltoken yes to no

Note if you will not do it your IAX Extension will not register as FAX services.

Submit and apply changes .

6- Now you can see under Fax >  Virtual FAX > Virtual Fax List

status   Running and idle on ttyIAX1

Elastix Voicemail to Email not working

I was trying to configure my Elastix voicemail to send voicemail on Email. but the email was not being delivered to the  my email address. I had configured properly my remote SMTP under mail configuration. I was able to send email from my elastix mail system and emails was being delivered to my email address.

But  Voice mail was not being delivered to users email address.

I started troubleshooting I checked the log

tail -f /var/log/maillog

I found below error message

Apr 16 01:29:26 localhost postfix/qmgr[1820]: 6B600C90A91: from=<asterisk@pockw.localdomain>, size=813, nrcpt=1 (queue active)

The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command))
Apr 16 01:29:49 localhost postfix/cleanup[1934]: 7537CC90A92: message-id=<20160415222949.7537CC90A92@pockw.localdomain>
Apr 16 01:29:49 localhost postfix/qmgr[1820]: 7537CC90A92: from=<>, size=3184, nrcpt=1 (queue active)
Apr 16 01:29:49 localhost postfix/bounce[1939]: 6B600C90A91: sender non-delivery notification: 7537CC90A92

The problem was asterisk@pockw.localdomain  which was sending voicemail to email it was not a proper email address and it was not being resolved by the DNS server as pockw.localdomain  was my server host name .

I found below article 

http://community.freepbx.org/t/change-from-email-for-voicemails/15735/3

As it says
in freepbx gui set serveremail in voicemail admin > settings to noreply@mydomainname.com

Above point I did not find in freepbx setting so I left that. and followed the next point.

edited /etc/postfix/main.cf
a. uncommented mydomain paramater in INTERNET HOST AND DOMAIN NAMES section
b. set mydomain = mydomainname.com
service postfix restart
accounts set to email voicemails as attachments are now receiving emails from noreply@mydomainname.com

Is it a bug that the postfix setting has to be manually changed?

Thats work for me it just changed the sender email address from asterisk@pockw.localdomain to asterisk@pockw.gkhan.in  but still mail was not being delivered.

Now I was getting below messge.

Apr 16 02:18:24 localhost postfix/cleanup[2354]: 143F1C90A91: message-id=<Asterisk-6-1160313698-111-2974@pockw>

Apr 16 02:18:47 localhost postfix/cleanup[2354]: 37D98C90A92: message-id=<20160415231847.37D98C90A92@pockw.gkhan.in>

Apr 16 02:18:47 localhost postfix/bounce[2359]: 143F1C90A91: sender non-delivery notification: 37D98C90A92
Apr

To resolve the issue I did the following .

I created a sub domain pockw.gkhan.in  and created a mx record pointed to gkhan.in mx record and created a email id user under  pockw.gkhan.in  as   asterisk@pockw.gkhan.in  .

Note :- All above i did it on my  Domain Cpanel .

Now the mails was being delivered successfully.

Apr 16 20:34:56 localhost postfix/cleanup[7935]: 66C17C90A91: message-id=<Asterisk-9-1233714121-111-2974@pockw>
Apr 16 20:34:56 localhost postfix/qmgr[2228]: 66C17C90A91: from=<asterisk@pockw.gkhan.in>, size=72822, nrcpt=1 (queue active)
Apr 16 20:35:21 localhost postfix/smtp[7938]: 66C17C90A91: to=<gkhanin@outlook.com>, relay=gkhan.in[173.254.220.66]:25, delay=25, delays=0.03/0.01/23/2.1, dsn=2.0.0, status=sent (250 OK id=1arU7o-0003I6-4t)
Apr 16 20:35:21 localhost postfix/qmgr[2228]: 66C17C90A91: removed

Now It was working fine and voicemail was being delivered to users email address.

I got good solution from below link on comment of Billsion . postfix-masquerade.

http://community.freepbx.org/t/solved-asterisk-does-not-respect-email-from-settings/9513

you can masquerade the sender email address to the real one which you want .which will accepted by the you SMTP server .

http://www.cyberciti.biz/tips/howto-postfix-masquerade-change-email-mail-address.html

Postfix MTA offers smtp_generic_maps parameter. You can specify lookup tables that replace local mail addresses by valid Internet addresses when mail leaves the machine via SMTP.

Open your main.cf file
# vi /etc/postfix/main.cf

Append following parameter
smtp_generic_maps = hash:/etc/postfix/generic

Save and close the file. Open /etc/postfix/generic file:
# vi /etc/postfix/generic

Make sure tom-01@server01.hosting.com change to tom@domain.com
tom-01@server01.hosting.com tom@domain.com

Save and close the file. Create or update generic postfix table:
# postmap /etc/postfix/generic

Restart postfix:
# /etc/init.d/postfix restart

When mail is sent to a remote host via SMTP this replaces tom-01@server01.hosting.com by tom@domain.com mail address. You can use this trick to replace address with your ISP address if you are connected via local SMTP.

I check with my PBX its working fine.

How to Install the noip Client on Linux

noip  provides free Dynamic DNS services  ( http://www.noip.com/remote-access) as DynDns was providing but its allow only three hostnames as free.

This guide will walk you through the installation and setup of the Dynamic Update Client (DUC) on a computer running Linux.  If you are using Ubuntu or Debian Linux please check our support site for guides on their specific setup.

If you are using Ubuntu Linux, please click here.

Installing the Client

The below commands should be executed from a terminal window (command prompt) after logging in as the “root” user.  You can become the root user from the command line by entering “sudo su -” followed by the root password on your machine.

Note: If you do not have privileges on the machine you are on, you may add the “sudo” command in front of steps (5 and 6).

1. cd /usr/local/src
2. wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
3. tar xzf noip-duc-linux.tar.gz
4. cd no-ip-2.1.9
5. make
6. make install

If you get “make not found” or “missing gcc” then you do not have the gcc compiler tools on your machine. You will need to install these in order to proceed.

To Configure the Client

As root again (or with sudo) issue the below command:

• /usr/local/bin/noip2 -C   (dash capital C, this will create the default config file)

You will then be prompted for your username and password for No-IP, as well as which hostnames you wish to update.  Be careful, one of the questions is “Do you wish to update ALL hosts”.  If answered incorrectly this could affect hostnames in your account that are pointing at other locations.

Now that the client is installed and configured, you just need to launch it.  Simply issue this final command to launch the client in the background:

• /usr/local/bin/noip2

Read the README file in the no-ip-2.1.9 folder for instructions on how to make the client run at startup. This varies depending on what Linux distribution you are running.

How to add driver in VMware ESX ISO .

While installing or upgrading VMware Vsphere servers some time we have to add the drivers in the ISO .which is not available in the  ISO .

In example I have to add Nexus 1000v VEM module in the ESXi 5.5 update 3 ISO . Which required to upgrade my ESXi 5.0 and support current running my Nexus 1000v VSM.

1- we have to get VMware Vsphere 5.5 update 3 bundle as ZIP from VMware website .

2-  Now create a folder and copy in it . in My Example I am copying in C:\Patch

3- Add ESXi offline bundle to Software Depot

Now open the VMware PowerCLI and run Below Command

PowerCLI > Add-EsxSoftwareDepot    c:\patch\ESXi510-201210001.zip

4- Now Copy the Driver Zip file in to C:\patch folder and add to the software depot

PowerCLI > Add-EsxSoftwareDepot  C:\patches\cisco-vem-v260-5.2.1.3.1.15.0-3.2.1.zip

5- Check the Driver is added to Software Depot

PowerCLI> Get-EsxSoftwarePackage  -Vendor Cisco

6- Check the Image profiles

PowerCLI> Get-EsxImageProfile

6-Now  Clone your  offline bundle image to a new image

PowerCLI> New-EsxImageProfile -CloneProfile ESXi-5.5.0-20151204001-standard -name Custom-cisco

7- Now check the vib list created in new Custom-cisco image

PowerCLI> (Get-EsxImageProfile -Name “brain-cisco”).VibList

8-  Get the name of vib added to image software depot

PowerCLI> Get-EsxSoftwarePackage -Vendor  Cisco

9- Add this vib to custom-cisco image

PowerCLI> add-esxsoftwarepackage -imageprofile Custom-cisco -softwarepackage cisco-vem-v260-esx

10- Now Export the Custom image as ISO

PowerCLI> export-esximageprofile  -imageprofile Custom-cisco  -exporttoiso  -filepath “c:imagebuilderbrian.iso”

11- Now you can compare offline base image to new Cusctom-cisco image

PowerCLI> compare-esximageprofile ESXi-5.5.0-20151201001s-standard Custom-cisco

How to get list of Virtual Machines with RDM PowerCLI
