Chapter 3 Configuring Your LibrarySetting Tape Drive ParametersScalar i500 User’s Guide 85• Auto (NL) — Auto-configure trying N-Port first (default)• The requested interface speed can be set to Auto (default), 1 Gb/s,2 Gb/s, 4 Gb/s, or 8 Gb/s (depending on drive type).• If the requested FC topology and speed settings are not supported,the next appropriate settings are negotiated. On the Web client, theDrive Settings screen displays both the requested and the actual FCtopology connection mode and interface speed. If FC drives are notconnected to the host, the negotiated actual settings appear on thescreen as “unknown.”Notes About Point to Point:- You can use Point to Point if the tape drive is connectedvia a switch.- You can use Point to Point with HP drives if the tapedrive is connected to a host.- You cannot use Point to Point if the tape drive isconnected directly to a host.- You cannot use Point to Point if the tape drive isconnected to an FC I/O blade.- You must use Point to Point if the tape drive is beingused for control path failover (see Configuring ControlPath Failover on page 151) or data path failover (seeConfiguring Data Path Failover on page 156). If a tapedrive is being used for control path failover or data pathfailover, you cannot change its topology from Point toPoint to anything else.Caution: LTO-5, LTO-6, and LTO-7 Fibre Channel tape drivescan be configured for speeds of up to 8 Gb/s. If theyare configured for 8 Gb/s, you should connect themdirectly to a host and not to an FC I/O blade, becausethe FC I/O blade only allows speeds up to 4 Gb/s. Ifyou connect an LTO-5 Fibre Channel tape drive to anFC I/O blade, you must configure the tape drivespeed to 4 Gb/s or less.Note: On the Web client, the Drive Settings screen displays tapedrive information in tables. Bold column headings in the tablescan be sorted. For example, selecting the Location columnheading will sort by location coordinates.
