Extended Data Lifecycle
Management
Extended Data Lifecycle Management (EDLM) provides data protection
and integrity checking by scanning your tape cartridges, providing
results, and allowing StorNext Storage Manager to migrate data off of
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 set up an EDLM library managed partition into which
tapes are moved for scanning. Scanning takes place using “EDLM
scanning drives.” You can use EDLM for manual scans at any time and
also set up automatic scanning policies.
EDLM is typically used to check the health of data on cartridges in long-
term retention (archive or disaster recovery) that are no longer used in
normal operations. (Conversely, health information for active cartridges
is presented in the Media Integrity and Media Usage reports, which are
part of the Advanced Reporting feature.).
