Configuring VSS in a physical environment 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 pool and reserved pool for VSS. Define the virtual hosts VSS_FREE_POOL and VSS_RESERVED_POOL on the storage system with the following example WWPN: 5000000000000000 and 5000000000000001.
3. Issue the following commands to set the example WWPN of the free pool and the reserved pool:
   • ibmvcfg set vssFreeInitiator
   • ibmvcfg set vssReservedInitiator
4. Map source volumes to the physical storage by iSCSI.
5. Map the target volumes to the free pool.
