Manually install the Storage Data Client (SDC) with the appropriate parameters to connect it to an existing PowerFlex system. This procedure applies to adding more SDCs to an existing system and adding SDCs to a two-layer system during initial deployment.

Before you start, ensure that you have:

• The virtual IP address or MDM IP address of the existing system. If an MDM virtual IP address is not in use, obtain the IP addresses of all the MDM managers.
• Login credentials for the intended SDC host.
• The required installation software package for the operating system of the SDC (available from the zipped software packages that you can download from the Customer Support site).
• A GUID string for the SDC. Tools that are freely available online can generate these strings. The GUID must conform to OSF DCE 1.1. The expected format is xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where each x can be a digit (0–9) or a letter (a–f).

Note: This procedure requires two server reboots.

To manually install an external SDC on an ESXi server using the ESXCLI command-line interface:

1. Install the SDC on an ESXi 7.0.x server:
   1. Copy the SDC file to the tmp directory on the local datastore on the host.
   2. Use SSH to connect to the host and run the following command: 

    esxcli software vib install -d /tmp/sdc-3.5.1100.101-esx7.x.zip --no-sig-check

3. Reboot the MX server node.

2. Run the following command to set the IP address of the MDM: 

esxcli system module parameters set -m scini -p "IoctlIniGuidStr=<XXXXXX> IoctlMdmIPStr=<LIST_VIP_MDM_IPS> IoctMdmPasswordStr=<ip>-<password> bBlkDevIsPdlActive=1 blkDevPdlTimeoutMillis=60000"

3. Perform another reboot.
4. Ensure that the driver is loaded:

vmkload_mod -l | grep scini

Output similar to the following indicates that the driver is loaded: 

scini 2 808

The SDC is installed on the ESXi server and is connected to PowerFlex. You can now create and map volumes to the compute nodes.
