This section describes an example of the configuration and readers are expected to refer to the Veritas Access Appliance and Everpure FlashArray product documentation for definitive and specific installation, administration, and configuration details.
The deployment example walks through the configuration of the Access Appliance as an NFS offload target for FlashArray as shown in Figure 10.
Figure 10 - Configuration Used in this Example Deployments
Outline of the steps involved in this example include:
- Configuration and storage provisioning of the Access Appliances as an NFS target.
- Configuration of FlashArray to utilize the Access Appliance as an NFS target.
- Validation of configuration by conducting a send to NFS and retrieval of snapshot from the Access Appliance.
ACCESS APPLIANCE STORAGE CONFIGURATION AND PROVISIONING
In this example, the Access Appliance graphical user interface (GUI) and command-line (CLI) is utilized to provision the storage. It is assumed that the Access Appliance has already been installed and connected to the same network as the FlashArray. Summary of steps to configure and provision Access Appliance as an NFS target involves the following:
-
Modify the permissions of share to have a user id and group id of 1000
CONFIGURE STORAGE POOLS
Step 1) Using a web browser, login to the Access Appliance graphical user interface: https://<consoleIP>:14161 . Click on “Go to Homepage”.
Step 2) Click on Infrastructure on left pane. Select the number of disks or volumes to be added to storage pool and click “Add to Storage Pool”.
Step 3) Select “Add to new storage pool”and enter a Storage Pool Name, i.e. ppool and click Next. On next screen, click Finish.
Step 4) Check the Activity icon, the clock on top and click on “Show All Recent Activities”. Wait until pool creation succeeds.
ENABLING NFS
Step 5) Click on Settings and in Share Services Management panes, click slider to right to enable NFS.
Step 6) Select KNFS to use Kernel NFS and click Start.
Step 7) Once complete, you will see that NFS is set to ONLINE.
CREATION OF FILE SYSTEM TO EXPORT AS NFS SHARE
Step 8) On left pane, click on File Systems and select Create File system in the page view.
Step 9) A wizard pops up and then follow wizard. Click Next.
Step 10) Enter name,file system type of CFS, size of the file system, then just use the defaults of simple layout and block size of 8192. Click on Select Storage Pool.
Step 11) Select the storage pool created in previous steps (i.e. ppool).
Step 12) Click Nextand then click Finish. Click on clock iconon top of page and wait for the creation of file system to succeed.
Step 13) Click Shares on left hand side and then click Provision Storage as an NFS Share.
Step 14) Select “Storage for NFS”.
Step 15) Select the file system created in previous steps, for instance, “va-nfs”.
Step 16) Set the pathname of the form “/vx/<file system name>”. Expand Options and select Read Write and Synchronous and click on “Set”. Click on Next.
Step 17) Review the summary details and click Next and Finish. Then, click on clock iconand wait for export of share to finish.
MODIFICATION OF NFS SHARE PERMISSIONS
Step 18) FlashArray requires a specific user and group (1000, 1000) to be able to write into the share. Thus, the ownership would need to be modified on the file system that will be exported as an NFS share. To modify the ownership, ssh onto one of the nodes to enter to the Access Appliance command-line interface (CLI). (NOTE: This is different from the Access cluster CLI). Once you enter the CLI, get into the Support and then the Maintenance views. Enter password as instructed and elevate to get into the bash shell of the Access Appliance. From here do a chown of file system as shown below. In this example, /vx/va-nfs was modified with user id and group id of 1000 which maps to user tomcat and admin in the Access Appliance. The “tomcat” user is not used within the Access Appliance.
