Exchange 2010 DAG and NIC Teaming | Team broke and now cluster doesn't see the box
Hello everyone,
Question for the group. We are running an Exchange 2010 DAG cluster with four boxes with active/passive DB's on each of the four boxes. We run HP boxes for Exchange and the NIC's are teamed. Now mind you, I arrived at this company well after this environment
was set up so I have inherited everything here.
What has happened is one of the four boxes had an issue after an otherwise normal reboot. We could no longer ping it. Logged into the ILO and was able to log into the server, only to discover its team NIC was messed up and our only option was to rebuild
the team NIC. So I rebuilt the team and gave it the original IP/subnet/gateway it had. The server reboots and we can ping it.
However, when I look in the EMC at Database Management, all the passive copies that were on that DB are showing Failed. Ok, so I suspend the copy and attempt to reseed. No luck. I get the error "The NetworkManager has not yet been initialized"
and it references my machine which had the bad team NIC. Curious, I go look at my Failover Cluster Manager.
Looking at the fail over cluster manager, I notice a X on the cluster and I am showing my server which had the bad team NIC being listed as down. I attempted to start the cluster service for the machine, but it did not work.
Is there something I a missing? What are my exact steps to take to get my cluster configuration working correctly again and see my box? Do I need to remove the box from the DAG, evict it from the cluster, and rejoin it again? If so, can I do this without
affecting the other three machines so users don't notice any outage?
Thanks for any help you can give!
Hi Kyle,
I am Chetan Savade from Symantec Technical Support Team & sorry to know the problem you faced because of SEP.
Symantec recommends that the Exchange server's OS always be protected by the latest available release of SEP. The Exchange server's message flow and Information Store must be protected by a dedicated mail security product, such as Symantec
Mail Security for Microsoft Exchange.
For cluster environment I would recommend to follow this article:
Installing the Symantec Endpoint Protection client to a Windows cluster server
http://www.symantec.com/docs/TECH91154
Installation best practices for Endpoint Protection on Windows servers

My
environment is as follows.<o:p></o:p>
We have 3 exchange 2010 servers.<o:p></o:p>
EX1, EX2, DREX1. All servers are exchange 2010 14.2 build 247.5<o:p></o:p>
EX1 and EX2 have two nics, one LAN and one for BACKUP <o:p></o:p>
The dag is configured to to communicate to all three.<o:p></o:p>
The IP for EX1 is 192.168.100.51 - LAN, switch A; 160.100.3.51 - BACKUP, switch B<o:p></o:p>
The IP for EX2 is 192.168.100.52 - LAN, switch A; 160.100.3.52 - BACKUP, switch B<o:p></o:p>
DREX1 is located in another network. It is in another building connected via vpn. The ip
for DREX1 is 192.170.100.51. There is no BACKUP network for this server<o:p></o:p>
(These are not the actual address, but the concept is similar)<o:p></o:p>
The dag network configuration is as follows.<o:p></o:p>
DAGNetworkDR has a subnet of 192.170.100.0/24; Network Interface of 192.170.100.51<o:p></o:p>
DAGNetwork01 (LAN) has a subnet of 192.168.100.0/24; Network Interfaces of 192.168.100.51
and 192.168.100.52<o:p></o:p>
DAGNetwork02 (BACKUP) has a subnet of 160.100.3.0/24; Network Interfaces of
160.100.3.51 and 160.100.3.52<o:p></o:p>
Last Friday, 3/7/14 something happened.<o:p></o:p>
To lead up to that, I noticed the issue because we have DPM 2010 making 15minute express
full backups of our exchange databases when I reviewed the backup jobs, the
exchange database backups using dpm2010 failed all weekend long starting at
11:00pm that Friday.<o:p></o:p>
The issue that occurred was that the database copies went to a status of Disconnected and
Resynchronizing, and after about 30 seconds, the status would show
Resynchronizing.<o:p></o:p>
All attempts to resolve this with the research methods failed. Deleting the
logs and reseeding failed, suspending, then rebuilding failed.<o:p></o:p>
Creating a new database worked, creating a database copy worked, but seeding the copy
failed. All with the same pattern, a status of Disconnected and
Resynchronizing, and after about 30 seconds, and the status would show
Resynchronizing.<o:p></o:p>
The database was mounted on EX2, and seeding to EX1
DREX1 has no issues.<o:p></o:p>
All the DAG networks were in a good status, all Green and all up. I could ping from
EX1 to EX2 and from EX2 to EX1 on both networks fine.<o:p></o:p>
In the middle of the week, about 3/12/14, we resolved the issue. We rebooted EX1, no
fix, but after rebooting EX2, it all resolved. It did a fail over to DREX1. I think it failed to do the failover to EX1. However, when it came back up, it was happy, it was reseeding slowly. After about an hour and a half, it
was all healthy.<o:p></o:p>
We thought it was all good EXCEPT, on Friday night at 11:00pmish on 3/14/14, the same
issue occurred; a status of Disconnected and Resynchronizing, and after about
30 seconds, the status would show Resynchronizing.<o:p></o:p>
The database was mounted on EX2 and seeding to EX1 again. I did not notice the
issue until I performed my review of the backup jobs again on Monday.<o:p></o:p>
Late Monday morning, my boss and I were looking at more articles, but all the same results,
delete the database copy and reseed. Which we knew would not work.<o:p></o:p>
I mentioned that it was strange because the networks were all up. What made us try the next
scenarios was just "luck" I guess. I made a statement about not remembering
which networks DAG replication took place over. Again, we have a LAN and
a BACKUP network. Bother were listed to use replication, so we decided to
disable replication over the BACKUP network in the EMC. Immediately, the
database copies switch to healthy and started seeding.<o:p></o:p>
Later that evening I enabled replication over the BACKUP network and it failed again with
a status of Disconnected and Resynchronizing, and after about 30 seconds, the
status would show Resynchronizing. I disabled the replication over the
BACKUP network and the database copy went back to healthy<o:p></o:p>
The last round of windows updates were pushed to these boxes the Friday before the
issues began, 2/28/14. I don't believe the updates to be the issue. <o:p></o:p>
Can anyone make any suggestions as to where to look? It worked with the BACKUP
network enabled to so long that is eluding me as to why the issues would start
all of a sudden. I am also confident that the switch configuration for the
BACKUP network has not been changed at all in at least 2-3 months. I am
still open to look at the config. Please help if you can.<o:p></o:p>
<o:p></o:p>
Lastly, this is more of a monitoring thing, if anyone can suggest a good way to monitor
the database copies so that I can be alerted when the status changes. We
use WhatsUpGold 16.2 to monitor the devices. <o:p></o:p>
Thanks for any future assistance.<o:p></o:p>

IanYou don't have to enable the Replication on Backup Network.
You should collapse your DAG network.

Exchange 2010 DAG backup & Transaction logs
Hi,
What is Microsoft recommended best practise for Exchange DAG group backup in an environment where there are Active & multiple (2-3) passive copies of the databases?
Is it a good practice to backup transaction logs as frequently as possible in addition to daily full backup ? This I belive will allow to restore the DB to the latest possible state
using last good full backup & transaction logs (Like restoring SQL databases)
ThanksHi,
Windows Server Backup can't backup passive copy. If you want to backup both active and passive copies, you need to use DPM or other third party.
Here is a similar thread for your reference.

Exchange 2010 dag with only 2 servers
I have my exchange 2010 running on win server 2012 R2 and I have installed another exchange 2010 server with the same FQDN and I want to configure DAG with only these 2 servers. Can I implement DAG with only 2 servers?Can the mailbox,client access and hub
transport roles still work with only 2 servers? If Mailbox and Hub transport could work it will be fine for me as CAS switchover can always be done manually.My main concern is securing data. Any article on how to implement that would be highly appreciated.
ThanksHi,
Yes, we can create a DAG with 2Servers and Each server can have upto 100 database depends upon Standard or Enterprise.

Exchange 2010 dag migration to exchange 2013 help
If I want to use the Same mailbox servers and upgrade them to exchange 2013, what is the recommended way? I have a 4 member exchange 2010 DAG.
I was thinking (where A,B,C,D are mailbox servers, A,B are in one site and C,D another active directory site):
A B -------------- C D
Remove A and C from the 2010 DAG, Format and install Exchange 2013 on both, and create a 2013 dag :
A1 ----------- C1
B ------------- D
Then move across all mailboxes from B to A1. Upgrade B and D to exchange 2013 and put them in the DAG
A1 B1 ----------- C1 D1
Does this make sense ? I am trying to do this while having as much high availability as possible during the transition. I have no extra servers so I have to use the existing server hardware.
Anand_NHi,
When you want to migrate a DAG from Exchange 2010 to Exchange 2013, you should first remove the mailbox server from the DAG in Exchange 2010 and then move mailboxes from database in this mailbox server to Exchange 2013. After all mailboxes have been migrated
to the Exchange 2013 mailbox server, when the new server is ready, it can become a member of the Exchange 2013 DAG.
Here is an article about migration DAG from Exchange 2010 to Exchange 2013 for your reference.

I downloaded 2 cds onto my ipod nano through itunes. Recently my itunes account changed for some unknown reason and now it doesn't recognize the songs from the cds. The songs are still on my ipod. I am affraid to sync now because the songs may be deleated, and I don't have the cds anymore. How can I transfer the songs from the cds on my ipod back to itunes so that I don't lose them?
What you have on your computer is your iTunes library, not your "account." The "account" you have for iTunes is your Apple ID, which you use when purchasing or downloading from the iTunes Store. If these songs came from music CDs that you imported into iTunes, those songs are not related to your Apple ID.
Recently my itunes account changed for some unknown reason and now it doesn't recognize the songs from the cds
How are they not "recognized"? Are the songs still listed in your iTunes music library, but grayed out? They no longer appear in your iTunes library at all?
If you search your computer (not in iTunes) for the song files, using one of the song names, can you find the song files? -
When I open Muse it comes up with a 'new version is available' and when I click on 'install now' it takes me to the adobe muse website where I click on the 'Download' button. It will then come up with 'Muse is downloading now'. It will then take me back to the Muse app again with the same 'install now' message. The new version has not installed, could some one please let me know the reason why it isn't installing.

How do I import an iPhoto Library (V.7.1.5) created on my old MacBook (10. 6.8) into my new Macbook pro (10.9.1) running iPhoto 9.5.1? I tried copying onto memory stick and moving to new mac, but new iPhoto doesn't recognise the library.
So what exactly did you copy over? If it's a 12 gig iPhoto Library then it sounds like the files are there. Perhaps the copy went wrong along the way.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

I saved my "users" folder to an external HD. I did erase and install on my imac. Now how do i get the accounts to open up on the fresh installation?
To move a home folder, create a new home folder, copy the contents of the old home folder into the new home folder, and then delete the old home folder. Take a look at this link, http://manuals.info.apple.com/en_US/UserMgmt_v10.6.pdf

I have prepared an 82 page book on iPhoto, ready to buy. There is a message over about half the photos saying "drag photo to place in background" as if it doesn't see the photo already there. I have spent over 20 hours getting to this point and can't bear to start over! Its a Mac 08X 10.6.8 and iPhoto 08 7.1.5. I have made other iBooks on this software and computer with no problems. Help please!
Look for a page that has a similar layout:
The one photo per page layout is the easiest to miss. Just click on a background color to remove the problem.

I downloaded an album from iTunes on my iPad and then i synced it with iTunes it doesn't show the individual songs in my library just the album which opens another window. One of the albums won't even play the music. Will only open the "booklet" for the cd but not the music. Can you help?
Hello dannugget
Normally, if the songs showed that it is purchased then it is probably already in your library. If not check out the article below to walk you through downloading your past purchases. You may also want to check to see if you have Automatic Downloads turned on so that way next time you can get your tracks without having to plug in and sync.

I purchased an audiobook in Nov 2012 using iPhone 4S and then upgraded to iPhone 5 in Dec. Now I am not seeing the audio book in purchase history in iTunes. This means I am not able to get the book in my new iPhone. Please help.
Audiobooks are currently a one-time only download from the store. If you don't have it on your computer (audiobooks go into the Books part of your iTunes library) nor on a backup, then if it's still in the store you can try contacting iTunes support and see if they will grant you a re-download : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
