Why does an application server fail to detect the mapped virtual disks after being configured with the UltraPath for Windows software?
The possible causes for a virtual disk detection failure include: ? The UltraPath for Windows software is incompatible with the Windows operating system installed on the application server. ? The UltraPath for Windows software is incompatible with the storage array. ? The LUNs are mapped to the application server before being formatted. ? The bit version of the UltraPath for Windows installation package is incompatible with that of the operating system running on the application server. For example, the application server runs a 32-bit operating system but uses a 64-bit installation package. ? The application server does not detect any physical disks, so it cannot produce virtual disks. ? The driver of physical disks is not replaced. The respective troubleshooting measures to the previous six causes are: 1. Confirm that the UltraPath software is installed on its supported operating system. The UltraPath for Windows-supported operating systems are Windows Server 2008 Enterprise Edition x86 SP1 and later, Windows Server 2008 Enterprise Edition AMD64, Windows Server 2003 Enterprise Edition x86 SP1 and later, Windows Server 2003 Enterprise Edition AMD64 SP1 and later, and Windows Server 2000 SP4. 2. UltraPath for Windows only supports the storage arrays from Technologies Co., Ltd. 3. Wait until the LUNs are formatted, and then scan for them on the application server. 4. Ensure that the operating system version is compatible with the installation package. If an inappropriate installation package has been installed, uninstall it first, restart the operating system, and then install the package of the proper version. 5. Check whether the physical links are normal. If they are normal, ensure that the LUNs are normal in the storage array and successfully mapped to the application server. 6. Check that the driver of physical disks is replaced. ? If the UltraPath software is not installed, before the installation, go to the C:\windows\inf directory and open all the inf files starting with oem. In each file, search for the following keywords: MPIODisk, Detected\MPIO, and Root\HWDSM. If a file contains one of the keywords, delete this oem.inf file and its related oem.pnf file. After ensuring that none of the oem.inf files contains the keywords, you can install the UltraPath software. ? If the UltraPath software is already installed, choose Computer Management > Device Manager > Disk Drivers to view the driver information of physical disks. If the driver of a physical disk is not mpdev.sys, the driver has not been replaced. Uninstall the faulty physical disk and rescan for disks. ? During service idle hours, restart the application server.
