Moving a CUCM cluster

Hi,
I have a few questions, we have a CUCM cluster, one Publisher and two Subscribers and one Voice mail server running on Linux servers from Cisco, version 6.2.
Is it possible to move the servers into a datacenter in another country and run the servers on VMware?
Can you install survilianse applications on a Cisco Linux CUCM server, like IBM's TSM?
Have anyone done this before so there is some examples on successfull moves?
Regards
Stellan Sveman

Upgrading cucm cluster

Hello everyone. I am facing an issue right now. The last weekend we upgrade our customer cucm cluster.
The cluster has 7 servers but finally we were able to upgrade 5 of the 7. 2 of them failed. I remove the servers from the publisher and turn them off. We need to reinstall the two servers but we do not have the bootable media at wich the cluster finally is working now. I am wondering if it is possible to install a 7.1.3 or another cucm version and after that upgrade to 8.6.2.22900-9.
Does any one has done this.?
Regards

No, all phones. Check out release notes:

How to know firmware version for all devices in a CUCM cluster

Hello,
We need to know the firmware version used for each one of the devices in a CUCM cluster (version 6.1)
Anybody know if we can get this info for example wit the BAT?
Thanks and regards,

You typically need to use a 3rd Party application to do this.
There are many that can do basic device information gathering, but if you are looking for a complete endpoint solution that scales to 10,000+ devices you should have a look at PhoneView from UnifiedFX (http://www.unifiedfx.com)
Thanks

Asking for advice for Jabber deployment - multi CUCM cluster\AD domains

I would like some design advice for deploying Jabber and CUPS in our company. We have 2 locations, west coast (SiteA) and east coast (SiteB). Each site have their own CUCM 7.15 clusters, Unity clusters, AD domains (trusted, but not in the same forest).
At SiteA I have setup CUPS (8.6.3.10000-20) and jabber and have it working great.
I would like to setup CUPS\Jabber for SiteB, but they need to be able to IM\call\etc to SiteA (And vice-versa).
SiteA and SiteB both have CUCM LDAP sync turned on, and LDAP directory synced with both domains (although SiteA cannot authenticate to CUCM at SiteB, and vice-versa due to the fact you can only LDAP sync authentication with one domain, CUCM user database contain users from SiteA and SiteB).
We have SIP trucks setup to pass internal calls and line status(BLF) between the trunks, and can communicate via internal extensions just fine.
The problem I’m running into is my jabber-config files uses the EDI directory – which can only look at one domain, so I cannot search the other domain. I believe changing to UDS fixes this, but I understand it would require me to upgrade both CUCM clusters to 8.6.2 - unless I’m mistaken.
I’m aware the desktop sharing will not work until CUCM is upgraded to 8.6.1 or 8.6.2.
I’m wondering if anyone has any advice, or can confirm I’m on the right track. Thanks in advance!

The thing that's important to understand is how CUP and Jabber build the XMPP URI. The URI has a left- and right-hand side; the left is the username while the right is the XMPP domain. CUP uses the LDAP attribute specified in CUCM's LDAP System page, sAMAccountName by default, for the left-hand-side. The right-hand side is the FQDN of the CUP cluster. Jabber must use the same values as CUP when displaying search results. Take note that nowhere in this process does the entire XMPP URI originate from the directory source.
In your case you have two separate CUP clusters in two separate domains. This won't work because when a user searches for a contact in the directory using Jabber, the client will build the XMPP URI as [email protected]. Even if you got the other domain's user objects into the search results the right-hand-side of the URI would be wrong and the presence subscription would never succeed since the other cluster is in another domain. As such your first task must be to move the CUP clusters into the exact same fully-qualified DNS domain. Once this is done you can use Inter-Cluster Peering to build a larger XMPP network in which all users have the same presence domain. If you intend to do Inter-Domain Federation in the future this must be your public DNS domain, not your internal active directory domain. If you use a non-public DNS domain TLS handshake will never succeed for inter-domain federation requests.
Once you have Inter-Cluster Peering in place you can use Active Directory Lightweight Directory Services (the new name for ADAM) to front-end both forests. Both CUCM clusters would need to import the full list of users representing both domains and the sAMAccountNames must be unique across both domains.
Finally, you can instruct Jabber to use UDS and query it's local CUCM cluster which will be able to return a search result from both domains. Since the CUP clusters are peered in the same domain the XMPP URI can be built properly, the presence subscription can be routed to the correct cluster, and life will be good.
By this point hopefully it's clear that EDI won't cut it since it would be limited to only returning search results from the local forest.
Please remember to rate helpful responses and identify helpful or correct answers.

Limit of CSR's or UCCE users per CUCM cluster?

Well my math and lack of documentation compete always, so trying to find max number of CSR's one can have, I understand it depends on ucce/ICM environment.
A cucm cluster with 8 subscribers fully loaded hw etc and moderate CSR skill sets and average number of queues:
Some others came up with around 2000 csrs max if we were to poppulate on whole cluster nothig but ucce users or csrs.
Is this limitation because of PG or CTIOS or what? if its due to PG can we have 2 PG's or total of 4 pg's (A and B sides) will this double CSR capacity to 4000?
As you may know capacity of cucm is 30K+ for users and devices.
Thoughts, facts or CCBU advice?
Thanks,
Baseer

If you using CTIOS as your desktop client you can run two PIMs on a CM PG for a max count of 4,000 agents. Unfortunately, if you are using CAD as your desktop client you are limit to a single PIM and I believe an agent count of 1,000 agents. CAD is very dense in relation to CTIOS. Also, if you plan on using a high number of mobile agents you need to count your agents with a heavier load. For CAD, 1 mobile agent translated to 1.7 agent load and CTIOS I believe is 1.3 agent load.
My understanding on the limitiations is with the code in the jtapi interface on the PG. While UCM CTI manager can process a higher agent count the jtapi interface on the PG cannot.
My two cents.

CUCM Cluster "Partition Unalligned" Issue Resolution by PCD (Prime Collaboration Deployment)

Dear all,
I will test soon (asap i got bootable 9.1.2 software) to solve "partition unalligned" issue with CUCM Cluster version 9.1.2.11900-12.
In my opinion, we can solve this issue with PCD as migrate unalligned cluster to a new cluster with same version.
Do anybody test it before?
What is your opinions?
Best Regards,
Mesut

Hi Aman,
As i found out, correct answer should be "migration to 9.x unsupported by CPD" for CUCM version 9.X.
But just imagine, you have 8 servers in a cluster at version 10.X with Partition Unalligned issue. Is PCD not a good alternative to DRS to solve this issue while migrating to a new cluster with PCD?
Best Regards,
Mesut

Moving CUCM Cluster from 7.1.5 to 10.5 and migrating P2V

Community - What I am looking for is advice from those who have actually done it! Reading about sex and having sex are two different subjects. I am finding relevant docs on the CISCO site, some are contradictory. One doc on CISCO Prime Deployment says yes to CUCM 7.1.5 and another says no. We know the standard "refresh" upgrade process, cop files and that entire drill. What we are looking for is comments from those who have done it before! Our Cluster is mixed MCS servers with CUCM PUB and SUB at Version 7.1.5. Unity/UCCX at 8.0.2 with no HA (don't ask). We want to end up with BE6000 and have UCCX in HA mode on Version 10.5 (10.6)! So what do you think, Migrate all in cluster to a common base like 9, then migrate to VM and upgrade? Or try to do it some other way.
All Comments welcome and very appreciated!

@Jamie I think we eliminated PCD as a strategy. We see this as following the usual upgrade process and assume we will be taking multiple steps. Step one would be to get all on a common version and we are thinking 8.5. At that point we could do the P2V and then upgrade to 10.5 on ESXi. We need to create some HA for Unity and UCCX, but will do that after we get to 10.5. Hopefully we can upgrade the CUCM Publisher, during which time the rest of the cluster will be operational? Put Pub back online as 8.5 and then do the subscriber. Again, we think UCCX and Unity will be operational on PUB as we upgrade SUB. Once on CUCM 8.5 we will then schedule maintenace windows to upgrade Unity and UCCX. At that point we have a cluster on 8.5 ready for P2V. We do that migration and when all are on ESXi, we do the upgrade to 10.5 and add in a HA server for UCCX and Unity. How does that sound? As we really dont want phones rebooting and downloading firmware, we will do that ahead of time, but are researching the level we should get them to before the 8.5 upgrade.
@Amn thanks for the link. We have been reading all we can on the CISCO site, and are really seeking out those who have done this and can share experience.
Thanks to all who comment.

VM will not boot after moving using Failover Cluster Manager - "a disk read error occurred......"

My current Configuration:
3 node cluster, using clustered shared storage and about 22 VM's.   The Host servers are running 2012 Data Center while all guest are running 2012 Standard. The SAN is EqualLogic and we are using HIT Kit 4.5.
I have a CSV that is running out of space, so I created another CSV so that I could move some of the VM's to a new home.    I tested this by creating a test VM, and moved it successfully 3 times.     I then moved an actual
LIVE VM and while it seemed to move ok, it will now not start.   The message is "a disk read error occurred Press ctrl+alt+del to restart".     I moved the test VM and it failed as well.
I have read several things about this, but nothing seems to relate to my specific issue.   I have verified that VSS is working and free of errors as well.    From the Settings menu for the VM, if I select "Inspect" the drive,
the properties all look fine.    It is a VHDX and both the current file size and maximum disk size seem correct.
The VM's were moved using the "move - virtual machine storage" option within Failover Cluster Manager.
Suggestions?
Thanks.

Lets see if I can answer all of those and I appreciate the brain storming.   This really needs to work, correctly.
1. The Storage is moving.
2.   VM's and SAN are on same device.
3. No, my Clustered Shared Volume, CSV, is out of room, (more one that later)
4. No, I actually have 2 sans grouped together.   However, I'm moving the VM', form one CSV to another CSV on the Same san. EqualLogic PS 6110 is the one I am trying to move VMS around on, and the other SAN not involved in any way except
for it is in a SAN group is an EqualLogic PS6010.
5. No error During move, it took about 5-10 minutes, no error messages.   Note, I did a test and it worked GREAT 3 times.   Now both a live VM, and the test VM are doing the same thing.
6. No, the machine is not to large.   The test making was a 50 gig drive, just 2012 standard installed with updates.   The live VM was a 75 gig VM that was my Trend Micro Server, or anti-virus host.
7. Expand the existing SCV?   Yes I should be able to, but there is an issue there.   The volume was expanded correctly, Equallogic sees the added space, Fail Over cluster manager sees the added space, however disk manager only
sort of does.    When looking at disk manager, there are 2 areas that tell you a little bit about the drive.   The top part and then the bottom part.   The top part only shows 500G, the original size, while the bottom part
says that it is 1 TB in size.   I call Dell's technical support and after they looked at it I was told by the technician that they had seen this a couple of times and the only way to fix it was to move all the VM's to another CSV and delete the troubled
CSV.   I thought about adding more space to the troubled CSV, but its on a production server with about 12 VM's running on it and I did not want to take a chance.   The Trend VM was running on CSV-1 and working fine.
I must admit that the test VM, was on CSV-2.    I moved the Test VM from csv-2 to csv-3 back and forth several times with no errors.   The Trend Server was on CSV-1 and was moved to CSV-3, however it failed. Again, I then moved
the test VM from CSV-2 to CSV-3 and it failed the same way.   I could not test the "TEST - VM" on csv-1 due to csv-1 not having enough space.
8.   I did disable the network from the VM to see if that mattered it did not.
9.   I have not yet had a chance to connect the VHDX to a new VM, but I will do that in about an hour, hopefully.    Once I am able to test that suggestion I will post the results as well.
Again, thanks for all the suggestions and comments, as I had rather have lots to look at and try.   I hope I answered them well enough.

CUCM Cluster with MCS-7845-I4

Hi,
I am doing a CUCM design for a customer with MCS-7845-I4 servers. We are building a Central solution with CUCM,CUPS, UCCX and Unity Connection.
There will be 4 CUCM servers. All gateways (about 40) will be H323, each with 1 E1 for PSTN. All gateways will have DSP for conferencing and Codec. MoH will be enable on CUCM. G.729 cross the WAN. G.711 to access Unity and UCCX from all sites configured with Regions to avoid codec issues.
The solution should support 2500 phones in phase 1.
My plan for Phase 1 is as follows:
1. Publisher/TFTP
2. Sub 1 - Sub 2(Primary and Failover)
3. Sub 3 - Sub 4(Primary and Failover)
4. Sub 2 and Sub 4 will be MoH
5. Sub 2 and Sub 4 will be backup for Media processing such as Conferencing. They will aslo Annuciator etc. This means I wont enable Cisco IP Voice Media Streaming App service on Pub, Sub1 and Sub 2
6. CTI manager will be enable on all subscribers
Question: Should I use backup TFTP on lets say Sub 2, what is your best experience?
The solution should support 8000 phones in phase 2.
My plan for Phase 2 is as follows:
1. Publisher
2. A separate TFTP server
Rest as Phase 1.
Question: Should I use backup TFTP on lets say Sub 2, what is your best experience? Can I manage phase 2 with Phase 1 design?
Any feedback would be much appreciated regards the total design, maybe you have a better design solution, maybe I have missed something here.
Br,
Mattias

Hi mattias,
It really looks like you've done your homework here
My one comment is on the need for "dedicated" TFTP servers;
TFTP Server
The TFTP server performs two main functions:
•The serving of files for services such as MoH, configuration files for devices such as phones and gateways, binary files for the upgrade of phones as well as some gateways, and various security files.
•Generation of configuration and security files. Most files generated by the Cisco TFTP service are signed and in some cases encrypted before being available for download.
The TFTP service can be enabled on any server in the cluster. However, in a cluster with more than 1250 users, other services might be impacted by configuration changes that can cause the TFTP service to regenerate configuration files. Therefore, Cisco recommends that you dedicate a specific server to the TFTP service in a cluster with more than 1250 users, with Extension Mobility, or with other features that cause configuration changes.
The TFTP server is used by phones and MGCP gateways to obtain configuration information. There is no restriction on the number of servers that can have TFTP service enabled, however Cisco recommends deploying 2 TFTP servers for a large cluster, thus providing redundancy for TFTP service. More than 2 TFTP servers can be deployed in a cluster, but this can result in an extended period for rebuilding of all TFTP files on all TFTP servers. When configuring the TFTP options using DHCP or statically, you can normally define an IP address array (more than one IP address) for a TFTP server. Therefore, you can assign half of the devices to use TFTP server A as the primary and TFTP server B as the backup, and the other half to use TFTP server B as the primary and TFTP server A as the backup. To improve performance on dedicated TFTP servers, you can set service parameters to increase the number of simultaneous TFTP sessions allowed on the server.
When upgrading a Unified CM cluster, Cisco highly recommends that you upgrade the TFTP servers after the publisher and before any other server, also allowing additional time following the upgrade for the TFTP server to rebuild all the configuration files. Either use the typical Cisco TFTP - BuildDuration time or use the real-time monitoring tool to monitor the Cisco TFTP - DeviceBuildCount until it stops incrementing. This upgrade order ensures that any new binaries and configuration changes are available before the upgrade of other services in the cluster. If you are manually adding a specific binary or firmware load for a phone or gateway, be sure to copy the file to each TFTP server in the cluster.
Cisco recommends that you use the same hardware platform for the TFTP servers as used for the call processing subscribers.

Moving Physical SQL Cluster into Virtual SQL Cluster based on Hyper-V Failover

Hello All............I have a SQL Cluster based on Physical Hardware that has Three-3 instances as well. I have setup a Hyper-V Failover Cluster (2012 R2) and have built Virtual/Guest SQL Cluster (2012 R2) upon it. Now, I intend to move
the instances/databases from Physical SQL Cluster to Virtual SQL Cluster.
1. Is this supported? If so, I would appreciate any guidance on it?
2. Is P2V of SQL Cluster supported in Hyper-V Failover Cluster based on Windows Server 2012 R2?

Hi Sir,
Please refer to the following blog regarding moving SCCVM SQL database to another SQL server:

But it seems that is a migration of system center production , I would suggest you to post the question to system center forum ：

Unable to Migrate VM's after moving from older cluster

Hello Everyone,
I have migrated 4 VM's from a 2008R2 SP1 failover cluster to a 2012 R2 failover cluster. The migration went off without a hitch, at least until I tried to live migrate one of the VM's to another node in the cluster. Below is the error I
get when attempting to live migrate the VM:
Cluster resource 'Virtual Machine Configuration TutorTrac' of type 'Virtual Machine Configuration' in clustered role 'TUTOR' failed. The error code was '0x2' ('The system cannot find the file specified.').
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.
The volume which stores the VHD's for the VM's can be migrated to all the nodes without incident. Does anyone know if this is a common problem? Does it have a "common" solution?
Thanks

Hi Sir,
1) You need to validate your cluster using cluster validation feature in-side Failover Cluster Manager. For doing this it would be better if you can bring all your cluster resources (VMs) down as it will validate all the resources and doing this in production
will result of service down. Validate all the cluster nodes for recommended all tests.
2) Make sure that within your Hyper-V manager on all cluster nodes you are keeping the Virtual Networks names same, ,like on your Hyper-V if you have created server_network for one of your virtual network for VM then this name should be same on all nodes
in the cluster.
3) Also for your VM make sure that ISO file is not attached when you trigger live migration, as if the cluster will not try to find it as shared between all nodes or on the destination node then it will through an error during live migration.

Elton Ji

Moving db to cluster

i have a customer that wants to move the sql db from sccm to a cluster,
i have the procedure how to do this, but the question is: what about the collation that is required for sccm?
if the sql cluster has not the correct collation, can we create a new instance and define the collation there, I thought collation is a sql server setting?

if the sql cluster has not the correct collation, can we create a new instance and define the collation there, I thought collation is a sql server setting?
Collation is set per-instance but can also be set per DB -- it is not a system wide system. I would highly recommend that if they go down this route they create a separate instance no matter what though so that resources (like memory) can be allocated specifically
and separately to the ConfigMgr DB and that the sysadmin requirement of the site server's computer account does not become an issue (note though the site server requiring local admin permissions on all systems/nodes in the cluster hosting the SQL instance
will most likely become an issue here though).
I'm with Garth here also -- doing this only provides on-paper benefits while increasing complexity, negatively affected perf, and not truly increasing availability.

Adding a new subscriber in CUCM 9.1.2 cluster cause all device reset

I am on CUCM version 9.1.2 ,whenever i add the subscriber /upgrade the subscriber to Cluster ,all the registered devices drops .
Not sure why ,In Cisco Documentation ,it never stated this bug in 9.1.2 service release notes.
However , In 9.1.1 mentioned about this in important notes.
CSCub12922: Adding a new subscriber causes device reset
After you install a new node in an existing cluster, all phones that are registered to the cluster are reset.
Anyone experienced ? or aware about this bug?
Is this the case going forward in any version after 8.X? for subscriber addition to cluster will reset the devices?
Thanks
Manoj

Hi Manoj,
As per the following bug
https://tools.cisco.com/bugsearch/bug/CSCub12922/?reffering_site=dumpcr
Symptom:
Add new subscriber to existing 8.x CUCM cluster cause all device reset
Conditions:
Adding a new subscriber to existing 8.x CUCM cluster cause all device reset due to database update. Issue recreated in lab when "Prepare Cluster for Rollback to pre 8.0" set to both true & false. The symptom and logs are the same in each scenario
This is not a bug. The condition is applicable only to CUCM 8.6 and higher releases. Whenever a node is added to CUCM cluster , from CUCM 8.6 onwards , the phones belonging to that Call Manager group will be automatically restarted
Workaround:
None
So, this applies to all 8.6+ releases of cucm.
