| + | ===== Windows ===== | ||
| + | Windows上有幾種作法，目前第一種作法是確定可行，第二種和第三種還在反證中或找明確文件: | ||
| + | * 與smartctl比對 | ||
| + | * 序號反轉 | ||
| + | * 使用PCI資訊 | ||
| + | 以下是我的範例:\\ | ||
| + | {{:pc:raid:megaraid:storcli_vd_win.png|}} | ||
| + | ==== smartctl ==== | ||
| + | smartctl的輸出中，有個Logical Unit Id會與SCSI NAA ID對應:\\ | ||
| + | {{:pc:raid:megaraid:smartctl_6.5_win.png|}} | ||
| + | ==== 序號反轉 ==== | ||
| + | <code> | ||
| + | 0x60030480070a14001dd43d642574735c # SCSI NA ID | ||
| + | 030480070a14001dd43d642574735c # remove 0x60，6為IEEE registered extended format | ||
| + | 5c747425643dd41d00140a07800403 # 以byte為單位反轉030480070a14001dd43d642574735c則為序號少開頭兩個0 | ||
| + | </code> | ||
| + | 序號可以到WMI中的Win32_DiskDrive中取得:\\ | ||
| + | {{:pc:raid:megaraid:wmiexplorer_win32_diskdrive.png|}}\\ | ||
| + | 假如你是使用diskid32去取序號，則是將030480070a14001dd43d642574735c字串反轉。 | ||
| + | ==== PCI ==== | ||
| + | 這方法只是推測，假如說LSI Card是在bus且有兩個virtual drive(ID為0與1)，在Win32_DiskDrive中的PNPDeviceID如下: | ||
| + | <code> | ||
| + | PNPDeviceID: SCSI\DISK&VEN_SMC&PROD_LSI2208\5&25F6E07A&1&010000 | ||
| + | PNPDeviceID: SCSI\DISK&VEN_SMC&PROD_LSI2208\5&25F6E07A&1&010100 | ||
| + | </code> | ||
| + | 尾巴的格式可能為1.0.0，也可能為010000；第一個byte應該就是bus，第二個就是fun也就是virtual drive id，第三個不重要省略。這個方法還需要測試與找明確證據。 | ||
| + | ===== Summary ===== | ||
| + | 在windows與liunx上最一致的做法，是藉由storcli與smartctl的比對，去找出VD與OS Path的對應；但要注意smartctl的GPL license與在linux上編譯執行檔參照函示庫的問題。 | ||
