Output similar to the following is displayed:
Controller = 0
Status = Success
Description = Add VD Succeeded
Results
The VD was created successfully.
Use PERCCLI to create virtual devices (VDs) for SSDs on a VxFlex Ready Node
server.
Before you begin
Ensure that the PERCCLI disk utility is installed.
Use this procedure both for SSD for storage and SSD to be used to provide caching
acceleration. The VDs created on SSD are configured with Direct IO and write-
through, but read-ahead is not enabled.
Procedure
1. Log in to the server.
2. Create the VD:
/opt/MegaRAID/perccli/perccli64 /c0 add vd type=raid0
drives=<EID>:<Slt> direct wt nora
Description
Create a VD that can be accelerated using the DAS Cache
utility:
/opt/MegaRAID/perccli/perccli64 /c0 add vd
type=raid0 drives=<EID>:<Slt> direct wt ra
pdcache=off
Example:
/opt/MegaRAID/perccli/perccli64 /c0 add vd
type=raid0 drives=32:6 direct wt ra pdcache=off
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
