Snapdrive Version 18.104.22.16819Windows Server Enterprise R2
When I try to connect to a lun everything looks like its going fine up until the last step. Then it gives me a timeout error, but the lun gets mapped and shows up fine after I restart computer manager and go back into snap drive. I can even take snapshots. It’s still there even after I restart the systems. I believe this problem can be resolved if I can increase the time out value which right now looks like its set to 120 seconds.
TimeOutValue setting used by the Host Utilities The Windows Host Utilities installer sets the disk TimeOutValue to 20 seconds for MPIO configurations and to 120 seconds for non-MPIO configurations. The installer skips this setting if Data ONTAP DSM for Windows MPIO is detected. The disk TimeOutValue parameter specifies how long an I/O request is held at the SCSI layer before timing out and passing a timeout error to the application above. The disk TimeOutValue setting for MPIO configurations changed to 20 from 60 seconds in Windows Host Utilities 5.1. This lower value improves failover performance. This parameter is set in the following Windows registry key: HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Services\Disk\ Attention: Installing the cluster service on Windows 2003 sets the disk TimeOutValue to 10 seconds. Upgrading the Emulex or QLogic HBA driver software changes TimeOutValue to 60
seconds. If cluster service is installed or the HBA driver is upgraded after you install Windows Host Utilities, use the Repair option to change the disk TimeOutValue back to 20 or 120 seconds. In the Windows Control Panel, launch Add or Remove Programs. Select Windows Host Utilities and click Change. Then click Repair to correct the TimeOutValue setting. If Data ONTAP DSM for Windows MPIO is installed, use the Repair option of the DSM installation program instead.
