Chapter 10: Path Failover
Configure Control Path
Quantum Scalar i6000 User’s Guide 373
4 From the Control Path (CP) Type drop-down list, select Advanced
Control Path Failover (HP) .
5 Select the primary control path drive from the CP column.
6 Select one or more drives from the CPF column. These drives will be
the failover drives.
7 Click Finish . An Operation in Progress dialog box appears.
8 The control path and control path failover drives are configured.
Advanced Control Path Requirements
To configure drives for advanced control path, you need the following:
• A Storage Networking (SNW) License must be installed on the
library (see Enabling Licenses on page 125).
• All drives must be licensed for SNW (see License Drives for Path
Failover on page 359).
• The drives must be IBM LTO-5 or later Fibre Channel drives.
• The tape drives must be connected to an Ethernet Expansion Blade.
• The tape drives must NOT be connected to an FC I/O blade.
• The tape drive topology must be set to Point-to-Point (see
Configuring Fibre Channel Drive Speed, Topology, and Loop ID on
page 202).
• The driver supplied by IBM must be installed on the host(s).
Configuration Guidelines
When a logical library partition’s media changer control path is
configured via a control path drive, the library control path is hosted by
the drive’s physical FC port and uses the same World Wide Port Name
(WWPN) associated with the selected tape drive. While the tape drive
(SSC device) responds as LUN 0 at the WWPN, the partition media
changer (SMC device) responds as LUN 1 at the WWPN.
For example, consider such a drive configured to host the library control
path. A switch could detect the tape drive as LUN 0 with WWPN
500308c0:9e2c3001 and detect the media changer as LUN 1 with
WWPN 500308c0:9e2c3001 also via switch port 1:
