Deploy Dell PowerFlex v3.6.x

If PowerFlex was deployed with the PowerFlex Gateway, the file already exists in the etc folder, with dummy values, and you will need to edit that file, and then copy it to the etc folder on every SDC/RFcache (RF) server in the system. The etc folder is located in:

• SDC

  Host	Path
  Ubuntu/OL	/etc/emc/scaleio/scini_sync/driver_sync.conf

• RFcache

  Host	Path
  Ubuntu/OL	/etc/emc/scaleio/xcache_sync/driver_sync.conf

The configuration of the driver_sync script is read from driver_sync.conf (an example appears below), which contains the following parameters:

Table 1. driver_sync.conf parameters

Parameter	Description
repo_address	Encodes the chosen method and address.
repo_user	Identifies the user name used when logging in to the drivers server. Required for SFTP and FTP methods.
repo_password	The FTP server login password (for user repo_user). Required for FTP method
user_private_rsa_key	Contains the path of the private RSA key file used to SFTP connection. This key file (provided by PowerFlex on installation) enables SFTP connection without a password.
local_dir	The local directory in which the downloaded SDC/RF drivers are stored. For SDC/RF clients, this value is set up during installation and doesn’t normally require a change.
repo_public_rsa_key	The path of the public RSA key of the repository server machine (also known as the host public key).
module_sigcheck	Determines whether to verify (1) or not to verify (0) the downloaded kernel drivers.
emc_public_gpg_key	A key that is used to verify signatures of downloaded drivers. Enter the path to the public GPG signing key of PowerFlex (just like the one that comes with PowerFlex LIA). This only needs to be set if module_sigcheck was set to 1.
The following parameters are used when driver_sync.sh is used to synchronize a local repository against a remote one.
sync_pattern	A regular expression that can be used to fetch several drivers at once. This parameter is not normally needed, and becomes relevant only when driver_sync.sh is used by your own private repository to fetch from a remote (e.g. Dell EMC) repository.
is_local_repo	Set to 0 (default) or omit, for SDC/RF clients. Set to 1 when driver_sync.sh is used to synchronize local repository against a remote repository. Setting to 1 will cause the fetched tar files not to be extracted.
