Configuring Volume Shadow Copy Service using iSCSI

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

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.

   Note: Each target volume must be exactly the same size as the corresponding source volume.
