Networking
n
In two-layer, bare metal systems, layer 1 contains SDS, MDM and LIA
components, and can use a 2-channel or 4-channel data network. Layer 2 (both
in ESXi and Linux systems) consists of SDCs only, on a 2-channel data
network.
n
The iDRAC component of each server should be configured.
n
vCenter (when used) must be configured.
l
Devices
n
On 14G servers running ESXi, NVMe SSD storage devices must be configured
as RDM. HDD and other SSD devices must be configured as DirectPath.
n
On 13G servers running ESXi, all devices must be configured as DirectPath.
Prerequisites
l
On RHEL nodes, ensure that the following packages are installed on every node:
n
libx86emu
n
hwinfo
n
perccli
n
ipmitool
n
smartmontools
n
lshw
n
sg3_utils
n
ntp
n

n
sas3ircu (copy the file to an executable path, and assign it execute
permissions)
l
Each VxFlex OS data network belongs to a unique subnet.
l
A VxFlex OS MDM virtual IP address must be configured on the two data networks
used by the SDCs.
l
All nodes (including SVM) nodes must be accessible via SSH.
Limitations
l
Nodes that were previously not successfully installed or properly configured will be
ignored during the take ownership process.
l
If the current node credentials do not match the VxFlex OS password policy,
prepare a CSV file with those credentials. The CSV will be used during the take-
