8Extended Data Lifecycle
Management
Extended Data Lifecycle Management (EDLM) provides data protection
and integrity checking by scanning your tape cartridges, providing
results, and allowing StorNext® to migrate data from bad or suspect
tapes. EDLM allows you to run manual scans on any tape cartridge in the
library at any time, and performs automatic scans according to schedules
and policies that you set up.
To use EDLM, you will set up one or more dedicated partitions to be used
for scanning. These partitions are called “library managed” partitions
because they are not accessible by hosts. You can manually scan a tape
cartridge at any time, or you can set up automatic scanning schedules and
policies. Scanning takes place using “EDLM scanning drives” which are
different from regular tape drives. You cannot use regular tape drives to
perform EDLM scans.
