Add storage controller (HBA) info to chassis layout output

Added get_storage_controllers() function that detects SAS, SATA, RAID,
and NVMe controllers via lspci. Updated all layout functions (10bay,
large1, micro) to display detected storage controllers with their
PCI address and model info.

+# AI-Assisted Development Notes
+
+This document chronicles the development of Drive Atlas with assistance from Claude (Anthropic's AI assistant).
+
+## Project Overview
+
+Drive Atlas started as a simple bash script with hardcoded drive mappings and evolved into a comprehensive storage infrastructure management tool through iterative development and user feedback.
+
+## Development Session
+
+**Date:** January 6, 2026
+**AI Model:** Claude Sonnet 4.5
+**Developer:** LotusGuild
+**Session Duration:** ~2 hours
+
+## Initial State
+
+The project began with:
+- Basic ASCII art layouts for different server chassis
+- Hardcoded drive mappings for "medium2" server
+- Simple SMART data display
+- Broken PCI path mappings (referenced non-existent hardware)
+- Windows line endings causing script execution failures
+
+## Evolution Through Collaboration
+
+### Phase 1: Architecture Refactoring
+**Problem:** Chassis layouts were tied to hostnames, making it hard to reuse templates.
+
+**Solution:**
+- Separated chassis types from server hostnames
+- Created reusable layout generator functions
+- Introduced `CHASSIS_TYPES` and `SERVER_MAPPINGS` arrays
+- Renamed "medium2" → "compute-storage-01" for clarity
+
+### Phase 2: Hardware Discovery
+**Problem:** Script referenced PCI controller `0c:00.0` which didn't exist.
+
+**Approach:**
+1. Created diagnostic script to probe actual hardware
+2. Discovered real configuration:
+   - LSI SAS3008 HBA at `01:00.0` (bays 5-10)
+   - AMD SATA controller at `0d:00.0` (bays 1-4)
+   - NVMe at `0e:00.0` (M.2 slot)
+3. User provided physical bay labels and visible serial numbers
+4. Iteratively refined PCI PHY to bay mappings
+
+**Key Insight:** User confirmed bay 1 contained the SSD boot drive, which helped establish the correct mapping starting point.
+
+### Phase 3: Physical Verification
+**Problem:** Needed to verify drive-to-bay mappings without powering down production server.
+
+**Solution:**
+1. Added serial number display to script output
+2. User physically inspected visible serial numbers on drive bays
+3. Cross-referenced SMART serials with visible labels
+4. Corrected HBA PHY mappings:
+   - Bay 5: phy6 (not phy2)
+   - Bay 6: phy7 (not phy3)
+   - Bay 7: phy5 (not phy4)
+   - Bay 8: phy2 (not phy5)
+   - Bay 9: phy4 (not phy6)
+   - Bay 10: phy3 (not phy7)
+
+### Phase 4: User Experience Improvements
+
+**ASCII Art Rendering:**
+- Initial version had variable-width boxes that broke alignment
+- Fixed by using consistent 10-character wide bay boxes
+- Multiple iterations to perfect right border alignment
+
+**Drive Table Enhancements:**
+- Original: Alphabetical by device name
+- Improved: Sorted by physical bay position (1-10)
+- Added BAY column to show physical location
+- Wider columns to prevent text wrapping
+
+### Phase 5: Ceph Integration
+**User Request:** "Can we show ceph in/up out/down status in the table?"
+
+**Implementation:**
+1. Added CEPH OSD column using `ceph-volume lvm list`
+2. Added STATUS column parsing `ceph osd tree`
+3. Initial bug: Parsed wrong columns (5 & 6 instead of correct ones)
+4. Fixed by understanding `ceph osd tree` format:
+   - Column 5: STATUS (up/down)
+   - Column 6: REWEIGHT (1.0 = in, 0 = out)
+
+**User Request:** "Show which is the boot drive somehow?"
+
+**Solution:**
+- Added USAGE column
+- Checks mount points
+- Shows "BOOT" for root filesystem
+- Shows mount point for other mounts
+- Shows "-" for Ceph OSDs (using LVM)
+
+## Technical Challenges Solved
+
+### 1. Line Ending Issues
+- **Problem:** `diagnose-drives.sh` had CRLF endings → script failures
+- **Solution:** `sed -i 's/\r$//'` to convert to LF
+
+### 2. PCI Path Pattern Matching
+- **Problem:** Bash regex escaping for grep patterns
+- **Solution:** `grep -E "^\s*${osd_num}\s+"` for reliable matching
+
+### 3. Floating Point Comparison in Bash
+- **Problem:** Bash doesn't natively support decimal comparisons
+- **Solution:** Used `bc -l` with error handling: `$(echo "$reweight > 0" | bc -l 2>/dev/null || echo 0)`
+
+### 4. Associative Array Sorting
+- **Problem:** Bash associative arrays don't maintain insertion order
+- **Solution:** Extract keys, filter numeric ones, pipe to `sort -n`
+
+## Key Learning Moments
+
+1. **Hardware Reality vs. Assumptions:** The original script assumed controller addresses that didn't exist. Always probe actual hardware.
+
+2. **Physical Verification is Essential:** Serial numbers visible on drive trays were crucial for verifying correct mappings.
+
+3. **Iterative Refinement:** The script went through 15+ commits, each improving a specific aspect based on user testing and feedback.
+
+4. **User-Driven Feature Evolution:** Features like Ceph integration and boot drive detection emerged organically from user needs.
+
+## Commits Timeline
+
+1. Initial refactoring and architecture improvements
+2. Fixed PCI path mappings based on discovered hardware
+3. Added serial numbers for physical verification
+4. Fixed ASCII art rendering issues
+5. Corrected bay mappings based on user verification
+6. Added bay-sorted output
+7. Implemented Ceph OSD tracking
+8. Added Ceph up/in status
+9. Added boot drive detection
+10. Fixed Ceph status parsing
+11. Documentation updates
+
+## Collaborative Techniques Used
+
+### Information Gathering
+- Asked clarifying questions about hardware configuration
+- Requested diagnostic command output
+- Had user physically verify drive locations
+
+### Iterative Development
+- Made small, testable changes
+- User tested after each significant change
+- Incorporated feedback immediately
+
+### Problem-Solving Approach
+1. Understand current state
+2. Identify specific issues
+3. Propose solution
+4. Implement incrementally
+5. Test and verify
+6. Refine based on feedback
+
+## Metrics
+
+- **Lines of Code:** ~330 (main script)
+- **Supported Chassis Types:** 4 (10-bay, large1, micro, spare)
+- **Mapped Servers:** 1 fully (compute-storage-01), 3 pending
+- **Features Added:** 10+
+- **Bugs Fixed:** 6 major, multiple minor
+- **Documentation:** Comprehensive README + this file
+
+## Future Enhancements
+
+Potential improvements identified during development:
+
+1. **Auto-detection:** Attempt to auto-map bays by testing with `hdparm` LED control
+2. **Color Output:** Use terminal colors for health status (green/red)
+3. **Historical Tracking:** Log temperature trends over time
+4. **Alert Integration:** Notify when drive health deteriorates
+5. **Web Interface:** Display chassis map in a web dashboard
+6. **Multi-server View:** Show all servers in one consolidated view
+
+## Lessons for Future AI-Assisted Development
+
+### What Worked Well
+- Breaking complex problems into small, testable pieces
+- Using diagnostic scripts to understand actual vs. assumed state
+- Physical verification before trusting software output
+- Comprehensive documentation alongside code
+- Git commits with detailed messages for traceability
+
+### What Could Be Improved
+- Earlier physical verification would have saved iteration
+- More upfront hardware documentation would help
+- Automated testing for bay mappings (if possible)
+
+## Conclusion
+
+This project demonstrates effective human-AI collaboration where:
+- The AI provided technical implementation and problem-solving
+- The human provided domain knowledge, testing, and verification
+- Iterative feedback loops led to a polished, production-ready tool
+
+The result is a robust infrastructure management tool that provides instant visibility into complex storage configurations across multiple servers.

+...
+```
+
+## How It Works
+
+### PCI Path-Based Mapping
+
+Drive Atlas uses `/dev/disk/by-path/` to create persistent mappings between physical drive bays and Linux device names. This is superior to using device letters (sda, sdb, etc.) which can change between boots.
+
+**Example PCI path:**
+```
+pci-0000:01:00.0-sas-phy6-lun-0 → /dev/sde → Bay 5
+```
+
+This tells us:
+- `0000:01:00.0` - PCI bus address of the LSI SAS3008 HBA
+- `sas-phy6` - SAS PHY 6 on that controller
+- `lun-0` - Logical Unit Number
+- Maps to physical bay 5 on compute-storage-01
+
+### Configuration
+
+Server mappings are defined in the `SERVER_MAPPINGS` associative array in [driveAtlas.sh](driveAtlas.sh):
+
+```bash
+declare -A SERVER_MAPPINGS=(
+    ["compute-storage-01"]="
+        pci-0000:0d:00.0-ata-2 1
+        pci-0000:0d:00.0-ata-1 2
+        pci-0000:01:00.0-sas-phy6-lun-0 5
+        pci-0000:0e:00.0-nvme-1 m2-1
+    "
+)
+```
+
+## Setting Up a New Server
+
+### Step 1: Run Diagnostic Script
+
+First, gather PCI path information:
+
+```bash
+bash diagnose-drives.sh > server-diagnostic.txt
+```
+
+This will show all available PCI paths and their associated drives.
+
+### Step 2: Physical Bay Identification
+
+For each populated drive bay:
+
+1. Note the physical bay number (labeled on chassis)
+2. Run the main script to see serial numbers
+3. Match visible serial numbers on drives to the output
+4. Map PCI paths to bay numbers
+
+**Pro tip:** The script shows serial numbers - compare them to visible labels on drive trays to verify physical locations.
+
+### Step 3: Create Mapping
+
+Add a new entry to `SERVER_MAPPINGS` in [driveAtlas.sh](driveAtlas.sh):
+
+```bash
+["your-hostname"]="
+    pci-0000:XX:XX.X-ata-1 1
+    pci-0000:XX:XX.X-ata-2 2
+    # ... etc
+"
+```
+
+Also add the chassis type to `CHASSIS_TYPES`:
+
+```bash
+["your-hostname"]="10bay"
+```
+
+### Step 4: Test
+
+Run the main script and verify the layout matches your physical configuration:
+
+```bash
+bash driveAtlas.sh
+```
+
+Use debug mode to see the mappings:
+
+```bash
+DEBUG=1 bash driveAtlas.sh
+```
+
+## Output Columns Explained
+
+| Column | Description |
+|--------|-------------|
+| **BAY** | Physical bay number (1-10, m2-1, etc.) |
+| **DEVICE** | Linux device name (/dev/sdX, /dev/nvmeXnY) |
+| **SIZE** | Drive capacity |
+| **TYPE** | SSD or HDD (detected via SMART) |
+| **TEMP** | Current temperature from SMART |
+| **HEALTH** | SMART health status (✓ = passed, ✗ = failed) |
+| **MODEL** | Drive model number |
+| **SERIAL** | Drive serial number (for physical verification) |
+| **CEPH OSD** | Ceph OSD ID if drive hosts an OSD |
+| **STATUS** | Ceph OSD status (up/in, down/out, etc.) |
+| **USAGE** | Mount point or "BOOT" for system drive |
+
+## Troubleshooting
+
+### Drive shows as EMPTY but is physically present
+
+- Check if the drive is detected: `ls -la /dev/disk/by-path/`
+- Verify the PCI path in the mapping matches the actual path
+- Ensure the drive has power and SATA/power connections are secure
+
+### PCI paths don't match between servers with "identical" hardware
+
+- Even identical motherboards can have different PCI addressing
+- BIOS settings can affect PCI enumeration
+- HBA installation in different PCIe slots changes addresses
+- Cable routing to different SATA ports changes the ata-N or phy-N number
+
+### SMART data not showing
+
+- Ensure `smartmontools` is installed: `sudo apt install smartmontools`
+- Some drives don't report temperature
+- USB-connected drives may not support SMART
+- Run `sudo smartctl -i /dev/sdX` manually to check
+
+### Ceph OSD status shows "unknown/out"
+
+- Ensure `ceph` and `ceph-volume` commands are available
+- Check if the Ceph cluster is healthy: `ceph -s`
+- Verify OSD is actually up: `ceph osd tree`
+
+### Serial numbers don't match visible labels
+
+- Some manufacturers use different serials for SMART vs. physical labels
+- Cross-reference by drive model and size
+- Use the removal method: power down, remove drive, check which bay becomes EMPTY

+
+## Contributing
+
+When adding support for a new server:
+
+1. Run `diagnose-drives.sh` and save output
+2. Physically label or identify drives by serial number
+3. Create mapping in `SERVER_MAPPINGS`
+4. Test thoroughly
+5. Document any unique hardware configurations
+6. Update this README
+
+## Technical Notes
+
+### Why PCI Paths?
+
+Linux device names (sda, sdb, etc.) are assigned in discovery order, which can change:
+- Between kernel versions
+- After BIOS updates
+- When drives are added/removed
+- Due to timing variations at boot
+
+PCI paths are deterministic and based on physical hardware topology.
+
+### Bay Numbering Conventions
+
+- **10-bay chassis:** Bays numbered 1-10 (left to right, typically)
+- **M.2 slots:** Labeled as `m2-1`, `m2-2`, etc.
+- **USB drives:** Labeled as `usb1`, `usb2`, etc.
+- **Large1:** Grid numbering 1-15 (documented in mapping)
+
+### Ceph Integration
+
+The script automatically detects Ceph OSDs using:
+1. `ceph-volume lvm list` to map devices to OSD IDs
+2. `ceph osd tree` to get up/down and in/out status
+
+Status format: `up/in` means OSD is running and participating in the cluster.
