Managing a Flex System V7000 manually

If an IBM® Flex System V7000 Storage Node is not discovered and inventoried automatically, use the IBM Flex System Manager management software to discover, inventory, and manage the Flex System V7000 manually.

About this task

After a new IBM Flex System V7000 Storage Node is installed in an Flex System Enterprise Chassis, the Chassis Map in the management software web interface shows the installed Flex System V7000 and provides a link to the Launch IBM Flex System V7000 EZSetup task. Use the Flex System V7000 EZSetup wizard to complete the initial setup the storage node.

After you complete the EZSetup wizard, the management software discovers the Flex System V7000 and collects inventory automatically.

Important: When the management software discovers and manages a Flex System V7000, the management software overwrites the preexisting SSH key for the user ID superuser. After the management process is complete, you can reapply the previous SSH key.

However, you might need to use the Manage Storage Systems page in the management software web interface and the command-line interface (CLI) to manually discover the Flex System V7000 for the following scenarios:

The Flex System V7000 is not discovered and inventoried automatically.
If a canister is removed or inserted after the Flex System V7000 has been discovered and inventoried.
The Flex System V7000 was previously configured in another cluster, and the Flex System V7000 was moved from one chassis to another.
Note: If the Flex System V7000 was previously configured in another cluster, an SSH key already exists for your user credentials. If the existing key is detected, the management software is not able to access and unlock the Flex System V7000.
To solve this problem, you might have to use a different user ID (one that does not have an SSH key configured) or delete the SSH key from the user ID and request access again. See Cannot unlock IBM Flex System® V7000 Storage Node for information about solving Flex System V7000 access problems.
An IBM Flex System Manager management node is installed in a chassis that already has a Flex System V7000 installed.

Note: This documentation is specific to using the Flex System V7000 storage node with IBM Flex System Manager management software in a Flex System environment. For more information about working with external storage resources, see Managing external storage resources.

Procedure

To manage a Flex System V7000 from the management software CLI, use the command smcli manageV7000. For example, you could use the following command to manage a Flex System V7000 from the management software CLI.

smcli manageV7000 -p <password_for_superuser> -i <Flex_System_V7000_IP_address>

To manage and discover the Flex System V7000 with the Discover storage task in the web interface, complete the following steps:

From the Home page, click the Additional Setup tab.
Click Manage System Storage. The Manage System Storage® page is displayed.
Click Discover Storage.
From the Select storage device type list, select IBM Flex System V7000 and Storwize V7000.
Specify the IP address or host name for the storage node.
Upload the SSH private key for the storage node. If you do not already have an SSH private key, complete the following steps to generate the key on the management node:
1. Log in to the IBM Flex System Manager management software CLI interface with the default systems-administrator credentials (USERID is the default user name).
2. Run the following command to create the key v7000_rsa.pub in the directory /home/USERID:
```
ssh-keygen -t rsa -f $HOME/v7000_rsa
```
3. When you are prompted, enter a key passphrase. If you prefer not to have a key passphrase, type nothing and press Enter. The name and directory of the SSH key are confirmed.
From the Manage System Storage page in the web interface, click Browse and select the SSH key from the directory where you saved it.
Important: The Discover storage task in the web interface does not generate a user with the same user name as the IBM Flex System Manager management software account that you are using to complete the Discover storage task on the Flex System V7000. If the task fails, you might need to create a user on the Flex System V7000 with the same user name as the IBM Flex System Manager management software account that you are using to complete the Discover storage task. To create this user on the Flex System V7000, see Working with remote and local users in the Flex System V7000 documentation.
If applicable, type your passphrase in the Key passphrase field.
Note: The Automatically run inventory when discovering devices box is selected by default. Unless you deselect the box, the management software will collect inventory for the Flex System V7000 after it is discovered.
Click Discover.
