The boot parameter of the controller card is defined.
Results
You have verified that the disks are in the UGood (unconfigured, but good) state and that the controller card boot
parameter is set to on. You can now create virtual drives.
Create virtual drives for an HDD using PERCCLI
Use PERCCLI to create virtual drives (VDs) for HDDs on a VxFlex Ready Node server. The devices can be used as part
of a Storage Pool or to provide caching.
Before you begin
Ensure that the PERCCLI disk utility is installed.
About this task
You need to create one VD for each HDD. The VDs for HDDs are configured with Direct IO, write-back, and read-ahead
enabled.
Procedure
1. Log in to the server.
2. Create a VD that can be accelerated using a utility such as RFcache, or that will not be accelerated at all:
/opt/MegaRAID/perccli/perccli64 /c0 add vd type=raid0 drives=<EID>:<Slt> direct wb ra
pdcache=off
Example:
/opt/MegaRAID/perccli/perccli64 /c0 add vd type=raid0 drives=32:6 direct wb ra
pdcache=off
where
<EID>
and
<Slt>
are the Enclosure ID and Slot ID values, identified in a previous step.
Output similar to the following is displayed:
Controller = 0
Status = Success
Description = Add VD Succeeded
Results
The VD was created successfully.
Create virtual drives for SSD using PERCCLI
Use PERCCLI to create virtual drives (VDs) for SSDs on a VxFlex Ready Node server.
Before you begin
Ensure that the PERCCLI disk utility is installed.
About this task
Use this procedure both for SSD for storage and SSD to be used to provide caching acceleration. The VDs created on
SSDs are configured with Direct IO and write-through, but read-ahead is not enabled.
Procedure
1. Log in to the server.
