Duplicate Media Changer Devices Discovered
You may see one or more media changer devices (partitions) being
discovered multiple times. For information on why this happens, see FC
I/O Blade Internal Virtual Port for Media Changers on page 111.
To prevent this, do the following:
• Ensure that host mapping is enabled (see Enabling/Disabling FC
Host Mapping on page 113).
• Assign each media changer a unique LUN and map each one to the
appropriate host (see Configuring Host Mapping
on page 118).
Identifying Tape Drives
You can use the operator panel and the Web client user interfaces to view
information about all tape drives installed in the library. In addition, you
can identify tape drives, including the control path tape drive, in selected
partitions. The Web client also allows you to identify tape drives that are
not assigned to specific partitions. On the Web client, you can only
identify tape drives that are in a ready state.
The operator panel
Drive Information screen lists the following
information for each tape drive:
• Control path tape drive status — yes/no
•Vendor
•Model
•Type
• Serial number
• Tape drive firmware version
• Sled boot version
• Sled application version
