Formatting Disk using DiskPart

Quite a while i’ve not post about Hyper V content.

Let look into several command that you should execute when formatting disk. Wait, won’t it be easy using Computer Management snap in to format a disk.

Well, you’re right but…you will not have Computer Management when Hyper V host machine is install with Server Core version.

Hope this command come to handy when you format a disk either local or iSCSI LUN presented to Hyper V host.

1. Execute Diskpart command.

image

2. Execute List Disk to view the disk available on the Hyper V machine

DISKPART > List disk

image

3. We are going to format disk 3. Execute select disk 3 to select disk 3.

DISKPART > Select disk 3
DISKPART > List disk

image

* indicated disk 3 is selected.

4. If the disk status is offline. Type

DISKPART > online disk

5. View the attribute of the disk. Make sure the disk read-only is not set to Yes.

DISKPART > attribute disk

image

If mark as Read-Only. Key in below command:

DISKPART > attribute disk clear readonly

6. Create primary partition using the entire disk volume.

DISKPART > create partition primary
DISKPART > list partition

image

7. Assign a drive letter

DISKPART > Assign letter =K

image

8. Quick format a disk with NTFS file format

DISKPART > format fs=ntfs quick

image

That’s all. Easy and simple. This is my last post for 2010. Wishing everyone “Happy New Year 2011”.

BMR on Windows Server 2003 using DPM

image
For those who has deployed DPM 2010, you would like to do Bare Metal Recovery on Windows Server 2003 and Windows Server 2008. You would be able to do BMR on Windows Server 2008 using DPM 2010 once you have install Windows Backup Features.
Now, how about Windows Server 2003?
Well, you can’t use DPM 2010 to do BMR for Windows Server 2003. For those who still want to do BMR, you need to separately download SRT on Microsoft Technet- DPM 2007 software. The size is around 341MB and you need to install on Windows Server 2003 operating system.
You can’t install together with DPM 2010 which resides on Windows Server 2008 R2 as this is unsupported.

The installation of SRT (System Recovery Tool) is quite straight forward and configuration is easy as well.
Note:- More information about SRT, please refer to http://technet.microsoft.com/en-us/library/bb808871.aspx

If you want to do BMR on cluster server, you need to apply the following hotfix:- http://support.microsoft.com/kb/947788

Here is some basic configuration that you need to perform.
1. Open DPM System Recovery Tool Console
2. Connect to Active Directory domain with valid domain authentication.
3. Create a schedule that you want the SRT to do recovery set.
Note: – SRT has it own recovery set and different from DPM recovery.
4. Add Computer into the schedule and create recovery set. The computer should be running Windows Server 2003. DPM SRT agent will automatically install into target computer. You need to make sure File and Printer Sharing is enabled.
Wait until the recovery set is complete and is successful.
5. Create a Client Boot Disk (SRTBootClient.iso) from DPM SRT Console.

Recovery
1.Make sure the original machine is down and offline.
2.Insert and boot from Client Boot Disk on new VM. (I’m using VM to test perform recovery. The VM must running legacy Network Adapter)
3. Wait to get IP address configuration or configure the ip address.
4. Open Recovery Center on SRT VM and select the computer that you want to recover. Select Rollback system options.

image

Follow the wizard to complete the recovery.
5. Recovery in progress.

image

Once complete, a HTML report will be displayed and target machine has rebooted.
Note:- The target machine should has identical hardware especially hard disk size should be bigger than original machine.

Recover Exchange 2010 Mailbox using DPM 2010–Part 1

This section is breaking down into three sections:
Part 1 – Scenario 1 and 2 (This section).
Part 2 – Scenario 3
Part 3 – Scenario 4 (coming soon)

Now let look into how to recover Exchange 2010 Mailbox.
To backup
Use Protection tab and create a protection group. The wizard will guide you to complete the step. The only thing that you should take note is ese.dll and eseutil.exe need to copy to C:\Program Files\Microsoft DPM\DPM\bin folder. If you did not, you will get below error message.

2

Enable eseutil.exe on
  • Both log and database when your exchange server is stand alone server
  • Log only when exchange is running DAG.
To recover
1. Create a Recovery database. Using Exchange Management Console (EMS), enter below command

3

New-mailboxdatabase –recovery –name RDB1 –server servername

To View the database
Get-Mailboxdatabase

Now, here got different scenario of recovery. Let look into the most common first before we go deep.

Scenario 1
1. User account and Mailbox deleted
Recovery not possible unless you recovery the user account first using System State recovery. Each user account has unique SID and you can’t create the same name of user account because the the system will create a new SID.

Scenario 2
1. User account and Mailbox account is still intact (not deleted) but message has deleted and the user would like to recover.
a) Set RDB1 as overwrite
Go to Exchange console > Organization Configuration > Database Management > Select RDB1 > Right Click > Properties > Maintenance tab > Tick This database can be overwritten by a restore.

5

2. Mount RDB1. Use EMS
“Mount-Database RDB1”

3. Use DPM to recover a mailbox. Example: Test1.
Before that, make sure you have created several recovery point. You cannot restore from the latest recovery point. Once you have done that, login to Test1 account and delete some email.

6

The status is listed “Online” mean the mailbox is still intact.
7

Select Recover to an Exchange Server database
8

Select Exchange Server which consist of Recovery Database- RDB1
9

Complete the wizard to finish the recovery.
4. Use EMS, to check recovery has transfer to RDB1
Get-MailboxStatistics –Database RDB1'

10

5. Use EMS, to recover mailbox from RDB1
Restore-Mailbox –Identity Test1 –RecoveryDatabase RDB1

11

6.Check that email message has restore using OWA.
This completed Part1- Basic recovery of mailbox when Mailbox is still intact.

Update DPM 2010 with QFE rollup

I just came back from Sri Lanka which completed a DPM project. During my project, i has updated the DPM 2010 to the latest QFE rollup. This QFE rollup has released on Nov 2010.

To download:- Click here

Installation of QFE rollup is quite simple and you need to restart the DPM server after patching the server.

Update from DPM Administrator Console
Once the server has restart, go to Management > Agents tab to upgrade the rest of the protected server agents. The new agent version will be upgraded to 3.0.7706.00.










Manual update installation
1. Navigate to C:\Program Files\Microsoft DPM\DPM\agents\RA\3.07706.0

32 bit- i386\1033\DPMAgentInstaller_KB2250444.exe
64 bit- amd64\1033\DPMAgentInstaller_KB2250444_AMD64.exe

The above path is also the new path for those who's perform manual agent installation.

DPM Service Failed When Erasing a Tape

Issue:-











1. I've checked the event log and found the following event


Log Name: Application
Source: MSDPM
Date: 12/20/2010 4:43:55 PM
Event ID: 943
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: Secret
Description:

The description for Event ID 943 from source MSDPM cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Unable to connect to the DPM database because the database is in an inconsistent state.


Problem Details:


<__System>19228712/20/2010 8:43:55 AMDpmThreadPool.cs163TrueDBCorruptionExceptionMore than one MediaPool reported for same Media aa1f597b-41d1-418d-b730-530c4f9efeb3Microsoft.Internal.EnterpriseStorage.Dls.DB.DBCorruptionException: More than one MediaPool reported for same Media aa1f597b-41d1-418d-b730-530c4f9efeb3

at Microsoft.Internal.EnterpriseStorage.Dls.Engine.CCoreServices.TriggerMediaEraseJob(CCoreServices* , _GUID mediaId, _GUID jobId, tagSAFEARRAY** exceptionResult)


2. Ran the following query and found it returns more than one row

prc_Global_MM_ArchiveMedia_GetMediaPool 'aa1f597b-41d1-418d-b730-530c4f9efeb3'

3. According to Microsoft PSS, they have checked in their internal database and found it is a bug in DPM 2010 which is still under investigation. The workaround to fix the problem is to run the following command:

a) Backup the database
DPMBackup.exe -db

Note:- the command is at C:\Program Files\Microsoft DPM\DPM\bin

b) Copy the DPMDb.bak into another location

Note:- the original backup database is located in C:\Program Files\Microsoft DPM\DPM\Volumes\Shadow Capy\Database Backups

c) Execute below command
SetSharedDpmDatabase -RemoveDatabaseSharing

Note: the command is at C:\Program Files\Microsoft DPM\DPM\Setup

d) Open DPM Administrator Console.

4. After the command succeeded, we perform detailed inventory on the tape library, it succeeded. Then we tried to erase a tape, DPM service did not crash and the job is in progress. Meanwhile, I create a new protection group to backup something to tape; the job was also in progress.

A bug...Gosh..

Should I do Teaming or MPIO on iSCSI NIC?

 

Some people confused when set high availability for iSCSI NIC.

Well, i dont blame them. Let get back to the question

Should I do teaming or MPIO on iSCSI NIC?

If you choose NIC Teaming, then answer is wrong !!!

No, NIC teaming is not supported on the iSCSI interface. Please see more info below:

Public: Network card that is used for connectivity with external clients. NIC Teaming is fully supported on this interface. See Network adapter teaming and server clustering for additional information.

Private: Network card that is used for internal cluster communication. NIC Teaming is NOT supported on this interface.

SAN: Network card that is used for communication to the storage device. NIC Teaming is NOT supported on this interface. Instead use Microsoft Multipath I/O (MPIO) or multiple connections per session (MCS per iSCSI specification) to achieve fault tolerance

Clarification taken from http://www.microsoft.com/windowsserver2003/technologies/storage/iscsi/iscsicluster.mspx

So since now you’re clear here is simple configuration that you should do on setting high availability on iSCSI NIC.

1. Configure iSCSI NIC 1 and iSCSI NIC 2 an ip address

2. Execute iscsicpl command and click “Quick Connect” to connect to iSCSI storage.

You will be able to see the LUN which has presented to your server

3. Select the LUN and click Connect. Do remember to select Enable Multipath and set to use iSCSI NIC 1

Repeat same process for all LUN.

4. On Server core, install MPIO feature

ocsetup MultipathIo /norestart

This will install MPIO feature and will not restart the server

5. Claim all iSCSI attached storage for MPIO

mpclaim -r -i -d "MSFT2005iSCSIBusType_0x9"

The server will restart . After restart, you can execute MPIOCPL.

You will see a new device hardware ID (MSFT2005iSCSIBusType_0x9) in the MPIO Devices tab

6. Now add a second path to each LUN and leave the default Round Robin Load Balancing.

Go to iSCSI Initiator, select the LUN and click Properties

7. Click Add Session > Tick enable Multi path > Click Advanced and select the iSCSI NIC 2.

8. Once complete, click Devices and select MPIO button. You will see two path on the LUN which has set to Round Robin.

9. To verify, execute

mpclaim –s –d

To view all LUN which has claimed in the MPIO

10. To verify MPIO policy according to disk #,

mpclaim –s id <disk #>

Now you have successful learn on how to set high availability on iSCSI NIC.

HP NIC Teaming on Server Core

 

Well, I'm a bit sceptical when deploy anything in Server Core at the first place.

As an additional tool from previous post:- http://www.ms4u.info/2009/12/managing-server-core-easy-or-hard-way.html

If you would like to do teaming on DELL Server, please refer to http://www.ms4u.info/2010/02/install-broadcom-advanced-control-suite.html

How about HP NIC Teaming?

1. Go to hp website and navigate to hardware driver.

2. Locate HP NCU (Network Configuration Utility) , download and install into Server Core

3. Then simply start hpteam.cpl from c:\program files\hp\ncu and do the usual GUI based configuration.

Is that simple? Never guess that NCU is working in Server Core.
