Collect IPMI sensors, SEL and dmesg errors into audit JSON and support bundle

- audit JSON: IPMI sensor readings (ipmitool sensor) merged into hardware.sensors alongside lm-sensors data - audit JSON: IPMI SEL entries (ipmitool sel list) in hardware.event_logs with source "ipmi-sel" - audit JSON: dmesg error/warning lines in hardware.event_logs with source "dmesg" (filtered by error/warn/AER/Xid/NVRM/ECC/panic patterns) - support bundle: added ipmitool-sensor.txt, ipmitool-sel.txt, ipmitool-sel-time.txt to techdump - saa_dmi.go: fix dmiItemRE to accept SHN with parentheses (e.g. PS(4)LC for PSU fields) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Fix SAA: set CWD=/usr/local/bin; include all SAA package binaries

Mikhail Chusavitin	5b5d8609d3	Refactor nav: remove numbers from Tools/Settings, add separator and Tasks item - Remove "6." / "7." prefixes from Tools and Settings nav labels and page titles - Add a horizontal separator (nav-sep) before the Tools/Settings group - Move Tasks into the nav as a regular nav-item after the separator, replacing the separate tasks-nav-btn at the sidebar bottom - Tasks item retains the active-count badge (tasks-nav-count) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-18 17:54:54 +03:00
Mikhail Chusavitin	e7442972d1	Move session-scoped LiveCD tools from Tools to Settings Tools page now contains only NVMe Block Format and Supermicro - DMI. Moved to Settings (7): - System Install (Install to RAM + Install to Disk) - Support Bundle + USB Black-Box - Tool Check - NVIDIA Self Heal (replaces simple NVIDIA Recovery card) - Network - Services Update TestToolsPageRendersNvidiaSelfHealSection to assert the moved cards on /settings instead of /tools.

Mikhail Chusavitin	4c6daa1c5e	Add SAA binary to ISO vendor, rename card to Supermicro - DMI - Extract saa 1.5.0 (Linux x86_64) into iso/vendor/saa — baked into ISO at /usr/local/bin/saa via the existing vendor loop in build.sh - Add saa to the vendor tool loop in iso/builder/build.sh - Rename the web UI card from "SAA - DMI" to "Supermicro - DMI" - Remove the redundant description hint about saa on PATH Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-18 17:49:12 +03:00
Mikhail Chusavitin	e420888d71	Add DMI test fixtures from linuxhw/DMI and expand placeholder detection Adds board and memory parser test fixtures based on real dmidecode output from Dell PowerEdge R740xd, HPE ProLiant DL380 Gen10, and Supermicro SYS-6028R-WTR sourced from the linuxhw/DMI dataset. Extends cleanDMIValue with four additional vendor placeholder strings found in the dataset: "0123456789", "1234567890", "NOT AVAILABLE", and "TO BE FILLED BY O.E.M" (without trailing dot). Adds memory_test.go covering mixed populated/empty DIMM slots and both GB and MB size formats. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-18 16:15:20 +03:00
Mikhail Chusavitin	8149360410	Fix SAA DMI parser to match real DMI.txt format Replace the guessed pipe/key=value parser with the correct format documented in SAA User Guide 4.8.1: [Section] Item Name {SHN} = "value" // comment Handles string values (strips surrounding quotes), non-string values (UUID, hex), section headers for display names, version line, and // comments. Verified against the SAA 1.5.0 User Guide sample. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-18 15:58:02 +03:00
Mikhail Chusavitin	4262c5b798	Add SAA DMI editor to Tools page Adds a new card to the web UI Tools page for reading and editing DMI fields via SAA (In-Band). Reads current DMI configuration with GetDmiInfo, displays all fields as an editable table, and applies only the changed fields via EditDmiInfo + ChangeDmiInfo. Backs up the original DMI file to dmi-backups/ before any write, making it available in the support bundle for rollback. Also adds "saa" to the standard tool check list.

Mikhail Chusavitin	b2e177af31	Bump DCGM to 4.6.0-1 to fix broken repo dependency NVIDIA removed datacenter-gpu-manager-4-core 1:4.5.3-1 from the repository and published 1:4.6.0-1. The cuda13 and proprietary packages still declared an exact-version dependency on 4.5.3-1 core, making the old pin unresolvable.

Mikhail Chusavitin	271dadda03	Restructure web UI navigation into 7 numbered workflow stages Replace the flat menu (Dashboard, Audit, Validate, Burn, Benchmark, Tasks, Tools) with a numbered progression that guides engineers through a logical acceptance workflow: Dashboard (landing) → 1. Audit → 2. Check → 3. Load → 4. Speed → 5. Endurance → 6. Tools → 7. Settings Key changes: - layout.go: numbered nav labels, new hrefs, Tasks removed from nav and replaced with a persistent sidebar badge (polls /api/tasks every 5 s, highlights amber when tasks are active) - server.go: 301 redirects from /validate→/check, /burn→/load, /benchmark→/speed for backward compatibility - pages.go: dispatch cases for all new routes; old routes kept as fallbacks - page_validate.go: add renderCheck() — non-destructive check page with validate-mode tests only (no stress toggle, no targeted-stress/ targeted-power/pulse cards) - page_burn.go: add renderLoad() wrapper; update scope alert to reference /check instead of /validate - page_benchmark.go: add renderSpeed() (performance focus) and renderEndurance() (stability/overnight focus) wrappers - page_settings.go: new Settings page with blackbox logging toggle, NVIDIA driver reset, and build info - server_test.go: update five tests to use new route names and content expectations Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-18 11:00:02 +03:00
Mikhail Chusavitin	20766ccc76	Order nvidia-fabricmanager after bee-nvidia to fix boot race bee-nvidia.service loads NVIDIA kernel modules; without After=bee-nvidia.service fabricmanager starts before /dev/nvidiactl is ready, fails, and relies on systemd restart to recover (~38s delay on affected systems).
