Suseno" Date: Tue, 9 Dec 2025 15:06:23 +0000 Subject: [PATCH] feat: Add complete iSCSI target management to Web UI- Add iSCSI tab with full target management- Implement create/delete targets with auto-generated IQN- Add LUN (backing store) management- Implement initiator ACL management (bind/unbind)- Add real-time target listing with LUN/ACL counts- Add comprehensive iSCSI management guide- Update sudoers to allow tgtadm commands- Add tape management features (create/list/delete/bulk delete)- Add service status monitoring- Security: Input validation, path security, sudo restrictions-

Target Naming + +- Use descriptive names (drive0, drive1, changer) +- Keep names short and simple +- Use consistent naming scheme +- Avoid special characters + +### 2. TID Management + +- Start from TID 1 +- Use sequential numbers +- Document TID assignments +- Don't reuse TIDs immediately after deletion + +### 3. Security + +- Use specific IP ACLs instead of "ALL" in production +- Regularly review ACL lists +- Monitor connection logs +- Use firewall rules as additional layer + +### 4. LUN Assignment + +- Reserve LUN 0 for controller +- Use LUN 1+ for actual devices +- Keep LUN numbers sequential +- Document LUN mappings + +### 5. Maintenance + +- Regularly check target status +- Monitor disk space on backing stores +- Keep tgt service updated +- Backup target configurations + +## Integration with MHVTL + +### Device Mapping + +``` +MHVTL Device → SCSI Device → iSCSI LUN +───────────────────────────────────────── +Library → /dev/sg0 → Target: vtl.changer, LUN: 1 +Drive 0 → /dev/sg1 → Target: vtl.drive0, LUN: 1 +Drive 1 → /dev/sg2 → Target: vtl.drive1, LUN: 1 +Drive 2 → /dev/sg3 → Target: vtl.drive2, LUN: 1 +Drive 3 → /dev/sg4 → Target: vtl.drive3, LUN: 1 +``` + +### Typical Configuration + +```bash +# 1.

+# mhvtl Configuration Web UI
+
+Web-based configuration manager for mhvtl (Virtual Tape Library).
+
+## Features
+
+- 📚 Library configuration
+- 💾 Drive management (add/remove/configure)
+- đŸ“ŧ Tape generation settings
+- 📤 Export configuration files
+- 🎨 Modern UI with Adastra theme
+
+## Usage
+
+### Local Development
+
+Simply open `index.html` in your web browser:
+
+```bash
+cd web-ui
+python3 -m http.server 8080
+# or
+php -S localhost:8080
+```
+
+Then open http://localhost:8080 in your browser.
+
+### Deploy to VTL System
+
+Copy the web-ui directory to your VTL system:
+
+```bash
+scp -r web-ui/ root@vtl-server:/var/www/html/mhvtl-config/
+```
+
+Or include it in the ISO build by adding to the build script.
+
+## Configuration Workflow
+
+1. **Library Tab**: Configure library settings (ID, vendor, serial, etc.)
+2. **Drives Tab**: Add/remove drives and configure each drive
+3. **Tapes Tab**: Set tape generation parameters
+4. **Export Tab**: 
+   - Generate configuration preview
+   - Download `device.conf` file
+   - Copy mktape command for tape generation
+
+## Generated Files
+
+- `device.conf` - Main mhvtl configuration file (goes to `/etc/mhvtl/`)
+- `mktape` command - Run this to generate virtual tapes
+
+## Integration with Build
+
+To include this in the ISO build, add to `build/build-iso.sh`:
+
+```bash
+# Copy web UI
+mkdir -p "$WORK_DIR/chroot/var/www/html"
+cp -r web-ui "$WORK_DIR/chroot/var/www/html/mhvtl-config"
+```
+
+## Customization
+
+Edit `style.css` to customize colors and theme. Current theme matches adastra.id branding.
