Install SDC on a Linux-based server and connect it to
PowerFlex
Install the SDC with the appropriate parameters to connect it to an existing
PowerFlex system. This procedure is relevant both for adding more SDCs to an existing system, and for adding SDCs to a two-layer system when deploying a new system.
Prerequisites
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 node
The required installation software package for your SDC's operating system (available from the zipped software packages that can be downloaded from the Customer Support site)
Secure Boot is not supported; ensure that Secure Boot is disabled in the BIOS
About this task
The following procedure explains how to manually install an external SDC on a Linux-based server. External SDCs can be deployed by the
PowerFlex Installer. For more information about adding components to an existing system, see the
Deploy Dell PowerFlex
Guide.
The steps in the procedure below are relevant for Linux RHEL/CentOS/Oracle Linux operating systems. Deployment on other operating systems require the modifications described in the following table:
OS
Modifications required
Ubuntu/OL
Before installing
PowerFlex, ensure that you have followed the required preparation procedures relating to various types of Linux operating systems.
PowerFlex component packages are delivered as TAR files. Before installing, perform the following:
Untar all the packages:
tar -xvf <tar_file>
This yields SIOB files.
Extract the DEB from the SIOB files:
siob_extract <siob_file>
The DEB file is in the following format:
EMC-ScaleIO-sdc-3.6-X.<build>.<operating_system>.X.X.x86_64.deb
You will use the extracted DEB files for the installation.
Some commands are a bit different, noted where applicable.
Steps
Install the GPG key on every server on which SDC will be installed. From the
PowerFlex installation folder, run the following command on every server:
rpm --import RPM-GPG-KEY-ScaleIO
In command line, install the SDC:
RHEL/CentOS /Oracle Linux/SLES
MDM_IP=<LIST_VIP_MDM_IPS> rpm -i <SDC_PATH>.rpm
Ubuntu (These files must be extracted before use, as described above.)
MDM_IP=<LIST_VIP_MDM_IPS> dpkg -i <SDC_PATH>.deb
where
<LIST_VIP_MDM_IPS> is a comma-separated list of all the MDM IP addresses or the virtual IP address of the MDM. Do not include
tiebreaker addresses here.
<SDC_PATH> is the path where the SDC installation package is located
To verify that the driver is loaded, the following command can be used:
SLES 15:
service sdc status
All other Linux flavors:
service scini status
Results
The SDC is installed on the Linux-based server, and is connected to
PowerFlex.
Next steps
In newly deployed systems, perform the post-deployment tasks described in this guide.
In existing systems, map volumes to the new SDCs that were added to the system.
