Good to remember:

What space reservation is

Data ONTAP uses space reservation to guarantee that space is available for completing writes to a LUN or for overwriting data in a LUN. When you create a LUN, Data ONTAP reserves enough space in the traditional or FlexVol volume so that write operations to those LUNs do not fail because of a lack of disk space on the storage system. Other operations, such as taking a Snapshot copy or the creation of new LUNs, can occur only if there is enough available unreserved space; these operations are restricted from using reserved space.

What happens when space reservation is disabled

You can create LUNs with space reservation enabled or disabled. If you disable space reservation, write operations to a LUN might fail due to insufficient disk space and the host application or operating system might crash. When write operations fail, Data ONTAP displays system messages (one message per file) on the console, or sends these messages to log files and other remote systems, as specified by its /etc/syslog.conf configuration file.

See How to use individual commands for information about creating LUNs with space reservation enabled or disabled.

What fractional reserve is

Fractional reserve controls the amount of space Data ONTAP reserves in a traditional or FlexVol volume to enable overwrites to space-reserved LUNs. When you create a space-reserved LUN, fractional reserve is by default set to 100 percent. This means that Data ONTAP automatically reserves 100 percent of the total LUN size for overwrites. For example, if you create a 500-GB space-reserved LUN, Data ONTAP by default ensures that the host-side application storing data in the LUN always has access to 500 GB of space.

You can reduce the amount of space reserved for overwrites to less than 100 percent when you create LUNs in the following types of volumes:

• Traditional volumes
• FlexVol volumes that have the guarantee option set to volume

If the guarantee option for a FlexVol volume is set to file, then fractional reserve for that volume is set to 100 percent and is not adjustable.

For detailed information about how guarantees affect fractional reserve, see How guarantees on FlexVol volumes affect fractional reserve.

How the total LUN size affects reserved space

The amount of space reserved for overwrites is based on the total size of all space-reserved LUNs in a volume. LUNs that do not have space reservation enabled are not included in the total LUN size. For example, if there are two 200-GB LUNs in a volume (400 GB total), and the fractional_reserve option is set to 50 percent, then Data ONTAP guarantees that the volume has 200 GB available for overwrites to those LUNs (400 GB total * 50% = 200 GB).

Note
Fractional overwrite is set at the volume level. It does not control how the total amount of space reserved for overwrites in a volume is applied to individual LUNs in that volume.

Command for setting fractional reserve

You use the following command to set fractional reserve:

vol options vol-name fractional_reserve pct

pct is the percentage of the LUN you want to reserve for overwrites. The default setting is 100. For traditional volumes and FlexVol volumes with the volume guarantee, you can set pct to any value from 0 to 100. For FlexVol volumes with the file guarantee, pct is set to 100 by default and is not adjustable.

Example

The following command sets the fractional reserve space on a volume named testvol to 50 percent:

vol options testvol fractional_reserve 50

How space reservation settings persist

Space reservation settings persist across reboots, takeovers, givebacks, and snap restores. A single file SnapRestore® action on a volume maintains the fractional reserve setting of the volume and the space reservation settings of the LUNs in that volume. A single file SnapRestore of a LUN restores the space reservation setting of that LUN, provided there is enough space in the volume.

The Active Directory Migration Tool version 3.2 (ADMT v3.2) simplifies the process of migrating objects and restructuring tasks in an Active Directory® Domain Service (AD DS) environment. You can use ADMT v3.2 to migrate users, groups, service accounts, and computers between AD DS domains in different forests (inter-forest migration) or between AD DS domains in the same forest (intra-forest migration). ADMT can also perform security translation (to migrate local user profiles) when performing inter-forest migrations.

System Requirements

• Supported Operating Systems: Windows Server 2008 R2
• ADMT can be installed on any computer capable of running the Windows Server 2008 R2 operating system, unless they are Read-Only domain controllers or in a Server Core configuration.
• Target domain: The target domain must be running Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2
• Source domain: The source domain must be running Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2
• The ADMT agent, installed by ADMT on computers in the source domains, can operate on computers running Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2.

For me it was AD permissions. Go to AD and find the mailbox in question.
Properties > Security > Advanced. Check the box to allow inheritable
permissions from parent. Let AD replication.

It support various remote management services like RDP, VNC remote control, SSH , RLogin and other host access.

The mRemote concept basic ideal is to reduce the system resources and cluttering up windows taskbar.

Meanwhile, user can easily run multiple instance connection to their remote terminal on a single application with multiple tabbing support.

To create the script, follow these steps:

1. Start Notepad.
2. Copy and paste the following code into Notepad:

   @echo =========  SQL Server Ports  ===================
   @echo Enabling SQLServer default instance port 1433
   netsh firewall set portopening TCP 1433 "SQLServer"
   @echo Enabling Dedicated Admin Connection port 1434
   netsh firewall set portopening TCP 1434 "SQL Admin Connection"
   @echo Enabling conventional SQL Server Service Broker port 4022
   netsh firewall set portopening TCP 4022 "SQL Service Broker"
   @echo Enabling Transact-SQL Debugger/RPC port 135
   netsh firewall set portopening TCP 135 "SQL Debugger/RPC"
   @echo =========  Analysis Services Ports  ==============
   @echo Enabling SSAS Default Instance port 2383
   netsh firewall set portopening TCP 2383 "Analysis Services"
   @echo Enabling SQL Server Browser Service port 2382
   netsh firewall set portopening TCP 2382 "SQL Browser"
   @echo =========  Misc Applications  ==============
   @echo Enabling HTTP port 80
   netsh firewall set portopening TCP 80 "HTTP"
   @echo Enabling SSL port 443
   netsh firewall set portopening TCP 443 "SSL"
   @echo Enabling port for SQL Server Browser Service's 'Browse' Button
   netsh firewall set portopening UDP 1434 "SQL Browser"
   @echo Allowing multicast broadcast response on UDP (Browser Service Enumerations OK)
   netsh firewall set multicastbroadcastresponse ENABLE
   

3. Save the file as a .txt file by using the following name: OpenSqlServerPort.txt
4. Rename the OpenSqlServerPort.txt file to the following: OpenSqlServerPort.bat

Before you run the OpenSqlServerPort.bat script, you must copy the script to the computer which has the firewall and then run the script on that computer. To run the script, follow these steps:

1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, use the cd command to navigate to the folder in which you saved the OpenSqlServerPort.bat file.
3. To run the OpenSqlServerPort.bat script, type OpenSqlServerPort.bat at the command prompt, and then press ENTER.
