Instructions


R630 ScaleIO Ready Node HBA330 SAS controller only RDM:

  1. Identify the disk in the ScaleIO UI, and get the SDS device current path.

Example:  /dev/sdh 

  1. SSH to SVM run the following command to map /dev/sdX dev to NAA # mapping:
   ls -l /dev/disk/by-id/ |grep wwn

list disk ID

  1. Record the disk in question's scli address or NAA # (it starts with 500*). 
  2. In vCenter, select the ESXi host in question and go to Manage -> Storage -> Storage Devices.
  3. Select each disk present and inspect the Identifier field of the Properties tab (under the Device Details section) for the NAA number in question:

RDM device esxi

  1. Once identified, select the Paths tab of the Device Details section, and record the Runtime Name of the disk in question: 

RDM device esxi 

  1. ESXi Runtime name T-value numbering starts at 1, and not 0 as iDRAC's does (Example: vmhba0:C0:T2:L0).
  2. In iDRAC, go to Storage -> Physical Disks, and select the disk with the name "Solid-State Disk 0:1:X," where X is 1 less than the T-value of the disk in question's ESXi runtime name.

Example: (ESXi  vmhba0:C0:T2:L0  = iDRAC Solid-State Disk 0:1:1)
