This topic describes adding and expanding storage devices after initial configuration. Delphix recommends expanding existing storage whenever possible; if it is not possible to expand Delphix recommends adding new LUNs of equal size to the existing storage pool.
Note for VMware Hypervisor (vSphere)
It is usually not necessary to reboot the Delphix Engine to add/expand storage if you're using vSphere.
If you followed the guidelines for adding your initial storage using all 4 virtual SCSI controllers, the Delphix Engine will see new storage without a reboot. On the other hand, if your new storage is leveraging a new virtual SCSI controller, you will need to reboot the Delphix Engine to detect the new storage. See Virtual Machine Requirements for VMware Platform for more information.
- Launch the ServerSetup application and log in using the sysadmin credentials.
- In the Storage section of the Server Setup Summary screen, click Modify.
- The Delphix Engine should automatically detect any new storage devices.
If a newly added storage device does not appear in in the Storage section of the Server Setup Summary screen, click Rediscover.
- Select Expand for each device that you want to expand.
The Expand checkbox appears next to the name of devices that have added capacity (in other words, the underlying LUN has been expanded), and the Unused column indicates how much capacity is available for each device. Newly-added devices will have a drop-down in the Usage Assignment column. Set the Usage Assignment to DATA for newly-added devices that you wish to add to the storage pool.
- Click OK.
WARNING: DO NOT REMOVE A CONFIGURED STORAGE DEVICE
Do not remove a configured storage device or reduce its capacity. Removing or reducing a configured storage device will cause a fault with the Delphix Engine, and will require the assistance of Delphix Support for recovery.
