• 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, the
Drive Settings
screen displays both the requested and the actual FC
topology connection mode and interface speed. If FC drives are not
connected to the host, the negotiated actual settings appear on the
screen as “unknown.”
The paths to open the appropriate screens are as follows:
• From the Web client, select
Setup > Drive Settings
.
• From the operator panel, select
Setup > Drive Settings
.
Working With Control Paths
The control path tape drive is used to connect a partition to a host
application.
The library automatically assigns control paths when you set up
partitions. You can modify the control path at any time. Table 5 describes
how these control paths are assigned and how to change them.
Caution: LTO-5 Fibre Channel tape drives can be configured for
speeds of up to 8 Gb/s. If they are configured for
8 Gb/s, you should connect them directly to a host
and not to an FC I/O blade, because the FC I/O blade
only allows speeds up to 4 Gb/s. If you connect an
LTO-5 Fibre Channel tape drive to an FC I/O blade,
you must configure the tape drive speed to 4 Gb/s or
less.
Note:
On the Web client, the
Drive Settings
screen displays tape
drive information in tables. Bold column headings in the tables
can be sorted. For example, selecting the
Location
column
heading will sort by location coordinates.
