IT35561: DOCUMENTATION DOES NOT MENTION THAT VMNOVRDMDISKS=YES RECREATES ALL VRDM DISKS AS THIN-PROVISIONED VMDKS, EVEN IF LUNS EXIST

APAR status

• Closed as documentation error.

Error description

• The documentation for the VMNOVRDMDISK=YES setting states that
  if the LUN for a vRDM is missing, the vRDM is restored as a
  thin-provisioned VMFS VMDK. However, this setting causes all
  vRDMs to be recreated as thin-provisioned VMFS VMDKs, including
  any vRDMs whose original LUNs are available.
  
  The product documentation needs to clarify the behavior of the
  VMNOVRDMDISKS=YES setting.
  
  The documentation for the VMNOVRDMDISKS is found in the IBM
  Knowledge Center at
  https://www.ibm.com/support/knowledgecenter/SSEQVQ_8.1.11/client
  /r_opt_vmnovrdmdisks.html
