Control Path Failover (CPF) and Data Path Failover (DPF) support for the TS7600 ProtecTIER Deduplication Solutions, V3.3.6

This topic details the Control Path Failover (CPF) and Data Patch Failover (DPF) that are supported by the emulated IBM library models.

Before you begin

Setting CPF/DPF within the IBM tape device driver is described in the IBM Tape Device Drivers Installation and User's Guide located on the following Web site: https://www-304.ibm.com/support/docview.wss?rs=577&uid=ssg1S7002972.

By default, Data Path Failover is always enabled on the emulated IBM library models and requires no feature code.

By default, CPF is also enabled on the emulated IBM library models. However, when troubleshooting host connectivity issues, you might be asked to disable CPF.
