Confirm with History Management (IM 36K10L20) in phase 9: how to load into older units, and whether a restart is really required. 2026-09-30 (phase 5): IM 36K10L35 §1.3/§5 explains the first part: event storage picks the unit by time stamp, never older than 60 units, and within the storage process's `gap_time` (ITHEEX/ITHEIX 2880 min) and, for EVENT/ITEM, `max_sample_delay` (ITHEIX 14400 min); older data needs earlier unit files (`hisdbg`, `hisrecover`, `isfrename`), `ithrecover <group> -p` and a restart. Practice in phase 9. 2026-10-01 (phase 9, verified): (1) restart **is** required — `CIENG_SCAN10S` / `CIENG_AGG` loaded at 11:54 and `CIENG_EVENT` reloaded at 11:32 stored nothing until the 12:00 restart, then stored at once. (2) The first unit of a new Event/Item or Aggregation group is dated 2 days back (= `gap_time` 2880 min), but samples loaded into that pre-restart unit (11:50, 30-Sep) were still dropped; samples inside the active unit (12:02) and inside a unit closed by a forced rollover (12:03 into unit 3,1) were stored. So: samples older than the first unit opened since the restart are dropped silently. Loading older data would need `hisrecover` / `isfrename` / `ithrecover` (not practiced).
