Deploy Dell PowerFlex v3.6.x

To ensure that a client node always has an SDC/RF kernel driver that matches the client kernel, the SDC/RF startup script uses driver_sync.sh, a synchronization utility that fetches SDC/RF kernel drivers from a configured repository. This repository can be either the Dell repository, or a local repository in your private network.

For Ubuntu nodes with PowerFlex SDC/RF drivers:

• The driver_sync.sh script is located, by default, at /bin/emc/scaleio/.
• In the repository, a driver package tarball is located at <base_dir>/Ubuntu/<PowerFlex_version>/<kernel_version>/scini.tar.

It may be necessary to manually restart the driver/s and services on hosts/servers hosting SDCs.

In a normal work flow, an SDC/RF driver will be loaded on boot. If there is a mismatch between the version of the running kernel and the kernel against which the driver was compiled, the driver_sync.sh script will be run automatically to fetch the appropriate driver. If the script fails for any reason (for example, due to incorrect configuration) after fixing the issue with the driver_sync.sh script, the driver services must be restarted manually, as described below. Root permission is required to run the commands.
