Dell EMC VxFlex Ready Node - Create Virtual Drives with PERCCLI; Verify the Storage and Disk Controller Status

l
For ESXi-based systems using DirectPath, connect to the SVM where the SDS is installed.
l
For Linux-based systems, connect to the SDS.
4. Install the PERCCLI package:
rpm -Uvh /tmp/perccli_linux_NF8G9_A07_7.529.00.tar.gz
Results
PERCCLI is ready for use.
Create virtual drives with PERCCLI
Create virtual drives (VDs) on drives using the PERCCLI utility. You are required to perform this step before adding
drives to a VxFlex OS SDS server in the VxFlex Ready Node system.
Note: Skip this step if the server contains the HBA330 controller or if you are configuring an VxFlex Ready Node
R840 system.
When creating virtual drives, the following rules apply:
l
Create one virtual drive for each kind of drive, HDD or SSD.
l
The VDs for HDD are configured with Direct IO, write-back, and read-ahead enabled (abbreviated in PERCCLI
as RWBD).
l
The VDs for SSD are configured with Direct IO and write-through, but read-ahead is not enabled. (Abbreviated
in PERCCLI as NRWTD.)
In the following PERCCLI command, 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.
The following table lists the different drive configurations on a VxFlex Ready Node R640 or R740xd server:
Node contains
Caching options
HDD for storage NA
Mix of HDD and SSD for storage Caching not used
Mix of HDD and SSD, where some HDDs or SSDs
are for storage and others provide acceleration
RFcache
Before creating VDs, you must gather some information about the drives and devices configured on each node.
Verify the storage and disk controller status
Before creating virtual drives (VDs), verify the storage and disk controller status.
About this task
In this task, use the PERCCLI utility to perform the following tasks:
