Adding FlashSystem 9x00 to a Storwize V7000 system

If you have an existing Storwize® V7000 system, you can add a control enclosure to the system. When the is added, the new system configuration adopts the attributes and supported features of the system, such as IBM FlashCore® Module support.

Before you begin

Update the code level of the enclosures in the Storwize V7000 system. You must update the Storwize V7000 system to the same code level as the control enclosure. For information on updating the system, see the Updating the system topic.

You must ensure that the Storwize V7000 system has licenses for all licensed functions. Additionally if the Storwize V7000 system manages externally virtualized storage, then the licenses for this capacity must be converted to storage capacity units (SCU) or terabyte licenses. Your sales team can help you with this process.

In addition to these licenses, both systems support encryption through an optional license. The support is the same, but if the Storwize V7000 system has an encryption license, the control enclosure must also have a license before it is added to the Storwize V7000 system. To activate an encryption licenses on the control enclosure, see the topic on activating the encryption license.

About this task

The existing Storwize V7000 system must include only models 2076-524, 2076-624, and 2076-724 control enclosures with the same code level as the control enclosure.

There must be fewer than four control enclosures in the existing system. (The maximum for both Storwize V7000 and systems is four control enclosures.)

If your IBM® Service Support Representative (SSR) is aware of your intent to add the to an existing system, the SSR installs the control enclosure for you, but does not initialize a system on it.

Procedure

To add a control enclosure to an existing Storwize V7000 system, complete the following steps:

If your Storwize V7000 system is currently licensed for compression, you must change the compression value to 0 before adding the control enclosure.
On the Storwize V7000 system, you can change the setting in the management GUI by completing these steps:
1. Select Settings > System > Licensed Functions.
2. On the Licensed Functions page, change the current setting for Compression to 0.
3. Click Apply Changes.
On the command-line, you can also issue the following command:
```
chlicense -compression 0
```
Ensure that the control enclosure is zoned correctly and is part of the same storage area network (SAN) as the Storwize V7000 system. The SSR installs the and completes cabling; however, you must complete all SAN configuration prior to installation and update the network planning sheets.
In the management GUI, select Monitoring > System. On the System -- Overview page, select Add Enclosure. When a new enclosure is cabled correctly to the system, the Add Enclosure action automatically displays on the System -- Overview page. If this action does not appear, review the installation instructions to ensure the new enclosure is cabled correctly. You can also add a new enclosure by selecting Add Enclosure from the System Actions menu.
Complete the instructions in the Add Enclosures wizard until the control enclosure is added to the system.

What to do next

After the control enclosure is added to the Storwize V7000 system, several post-installation tasks can be necessary to fix potential configuration issues.

Verify that system attributes have updated to the status of the system as a system by completing these steps:
1. In the management GUI, select the help icon and select About and verify the following attributes to ensure the system is now identified as a system:
  - Product name:
  Other system attributes also change, such as Call Home prefix and support site URLs, when the control enclosure is added to the Storwize V7000 system. These changes are expected but might seem confusing unless you are aware of them. Any system that has control enclosures is considered to be a system.
2. If you did not have any external virtualization licenses on the Storwize V7000 system, then no additional updates to license settings are necessary.
3. If you did have external virtualization licenses on the Storwize V7000 system and contacted your sales team for setting that converted enclosure-based licenses to capacity-based licenses, use those values to update the license settings on the system. In the management GUI, select Settings > System > Licensed Functions or use the chlicense command.
