Filled Capacity Information In addition to tracking media health and
generating reports, MLM displays a Filled Capacity bar graph on the
General Status screen. This graph shows the remaining uncompressed
storage capacity for the MLM-enabled media in the entire library or in a
specific partition. Click on the Filled Capacity bar graph to view the Media
Lifecycle Management Report screen (Figure 170 on page 300).
Note: Until a data cartridge is loaded into, threaded, and then
unloaded from a drive for the first time, its data capacity is not
included on the Filled Capacity bar graph shown on the General
Status screen.
Media Alert The Media Alert feature generates a system message when a
tape’s health is identified as poor (red) during five consecutive loads. This
message is only generated once per tape. A separate system message is
generated whenever a cartridge experiences a hard error.
Tracking Non-MLM-Enabled Media MLM tracks the basic health
information for LTO data cartridges that are not MLM-enabled. This basic
health information is based on tape log data retrieved from an MLM-
capable LTO drive (LTO-4 or later generation) when the cartridge is
ejected. The data pertinent to media health is stored in the MLM database
and used to determine the media health status (Usable or Impaired)
included in Media Lifecycle Management reports.
Figure 156 The General Status screen shows the storage capacity usage for the selected
partition.
