Enable PERCCLI on a host server

Creating virtual devices with PERCCLI

Enable the PERCCLI disk utility on a VxFlex Ready Node host server.
Before you begin
Ensure that you have:
Root access to the server on which PERCCLI is to be installed
l
Internet access to enable you to download the PERCCLI utility
l
Procedure
1. Download PERCCLI from
perccli-1.17.10-1.noarch.rpm.
2. Copy the installation file, perccli-1.17.10-1.noarch.rpm, to the /tmp
folder on the node.
3. From the Linux console or via SSH, install the PERCCLI package:
rpm -Uvh /tmp/perccli-1.17.10-1.noarch.rpm
Results
PERCCLI is ready for use.
The following tasks explain how to create virtual devices (VDs) on disks using the
PERCCLI utility. You need to perform these steps before adding disks to a VxFlex OS
SDS server in the VxFlex Ready Node system.
Note
If the server contains the HBA330 controller, skip this step.
When creating virtual devices, note the following:
Create one virtual device for each kind of disk, HDD or SSD.

When DAS Cache is not used, configure the VDs for HDD with Direct IO, write-
l
back, and read-ahead enabled (abbreviated in PERCCLI as RWBD).
When DAS Cache is used, configure the VDs for HDD with Direct IO, write-
l
through, and read-ahead enabled (abbreviated in PERCCLI as RWTD).
Configure the VDs for SSD with Direct IO and write-through, with read-ahead not
l
enabled (abbreviated in PERCCLI as NRWTD).
In the PERCCLI commands that follow, the controller ID is assumed to be 0,
designated by /c0. In some cases, the controller ID may be different, which will cause
a Controller 0 not found error to be displayed. If this occurs, determine your
controller ID by running the following command:
/opt/MegaRAID/perccli/perccli64 show
The controller ID is displayed in the System Overview section of the output, in the
Ctl column.
