Configuring Volume Shadow Copy Service using iSCSI

You can use iSCSI when you configure the VSS provider in a physical environment.

Procedure

  1. Connect to the storage using CIMOM.
  2. Create the free storage pool and reserved storage pool for VSS. Define the virtual hosts VSS_FREE_POOL and VSS_RESERVED_POOL on the storage system with the following sample WWPN: 5000000000000000 and 5000000000000001.
  3. Issue the following commands to set the sample WWPN of the free storage pool and the reserved storage pool:
    • ibmvcfg set vssFreeInitiator
    • ibmvcfg set vssReservedInitiator
  4. Map the source volumes to the physical storage by iSCSI.
  5. Map the target volumes to the free storage pool.
