Uninstalling Fluid Cache For DAS

Use Dell OpenManage Server Administrator or the fldc tool to disable caching on the back end disks.

1. To disable using fldc, at the prompt, run the command: fldc --disable --disk=<disk_name>

NOTE: Run this command for each configured disk.

2. Remove all cache devices from the cache pool. To remove a PCIe SSD, run the command: fldc --remove --

ssd=<ssd_name>

NOTE: Run this command for each configured disk.

3. Run the command: rpm -qa | grep DAS to get the Fluid Cache for DAS package name.

4. Use the rpm -e command to remove the Fluid Cache for DAS package from the server. For example, run the

command: rpm –e <extract_package_name>

5. Optionally, you can remove the /opt/dell/fluidcache directory to remove all components of Fluid Cache for DAS from

your installation. At the prompt, run the command: rm -rf /opt/dell/fluidcache

NOTE: If you attempt to reinstall Fluid Cache, you may see a warning message that advises that you have had

a previous configuration. You cannot clear that warning and install FluidCache unless you remove the

FluidCache directory. Remove the FluidCache directory after you are sure that all data previously managed by

Fluid Cache is secure.

Fluid Cache for DAS is now uninstalled.
