Displaying control paths
This section introduces two ways to view the control paths of the TS3500 tape library.
The TS3500 tape library has no direct SCSI connection to a server. Thus, when a server communicates with the library, it must send the communication through an Ultrium tape drive or 3592 tape drive that is designated as a control path. A control path is a logical path into the library through which a server sends standard SCSI Medium Changer commands to control a specific logical library. When you add multiple control paths to the TS3500 tape library, any single, configured logical library can be accessed by multiple servers. Additional control paths also reduce the possibility that failure in one control path will cause a loss in host communication for the entire library.
- Microsoft Windows 2000 Removable Storage Manager (RSM) does not support multiple control paths within a logical library.
- Logical libraries with a maximum number of cartridges greater than 6 887, or with shuttle stations assigned, must use LTO Ultrium 4, 3592 E05, or later tape drives as control path drives. To support more than 6 877 cartridges, Ultrium 4 control path drives require a minimum code level of 97F0. To support shuttle stations, Ultrium 4 control path drives require a minimum code level of A480 and Ultrium 5 control path drives require a minimum code level of B170.
To display control paths, use one of the following methods.
