Note: in 4.1.x and older you are not able to remove storage from the Delphix Engine, in 4.2 and newer this capability has been added please see Device Removal. There were several critical bugs with device removal in earlier releases of Delphix so it is highly recommended to use this feature with Delphix 5.1 and higher. Known issues include:
Delphix Engine May Fail to Restart Following Device Removal (TB034)
Device Removal May Lead to Delphix Engine Crash
Device Removal if Used after Upgrade to Specific Versions May Lead to Crash
Option 1: Adding New Luns
If it is available you can add more LUNs to the Delphix Engine
Launch the ServerSetup application and log in using the sysadmin credentials.
The Delphix Server 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.
In the Storage section of the Server Setup Summary screen, click Modify.
The Expand checkbox appears next to the name of devices that have added capacity, and the Unused column indicates how much capacity is available for each device.
Select Expand for each device that you want to expand.
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 Server, and will require the assistance of Delphix Support for recovery.
Option 2: Deleting Objects to Increase Capacity
- Log into the Delphix Admin application using delphix_admin credentials.
- Select Resources > Capacity.
- Select the groups or objects you want to delete.
As you select items, you will see them added to the Total Capacity of Objects Selected for Deletion.
- Click Delete.
Listing Objects in the CLI
- Log into the Delphix CLI using delphix_admin credentials.
- Enter database.
- Enter list. You can find a list of all your dSources and VDBs here.
Listing Objects in the GUI
- Open your Delphix Engine GUI and log in using delphix_admin credentials.
- Navigate to Manage > Dashboard.
- In the Performance Management secion, you can find a list of dSources and VDBs.
Option 3: Changing Snapshot Retention to Increase Capacity
Log into the Delphix Admin application using delphix_admin credentials.
Select Resources > Capacity.
Click in the Keep Until column for the snapshot you want to edit.
Select the number of days you want to preserve the snapshot.
Click outside the column to set the change.
Option 4: Use vMotion to move to new LUNs
Use vMotion as you would normally but please be aware of the following:
vMotion of a VM can be done with the VM running or shut down. If the VDB server, the target, will be running when vMotioned, then there should be nothing at all to do on the Delphix Engine. A live vMotion is a transparent operation. If you plan to shut down the VM and vMotion it while powered off, then you would need to shut down the VDB(s) first through the Delphix Engine GUI.
