HP Surestore Auto Path Virtual Array for Windows NT Installation and User's Guide

Troubleshooting 67
Troubleshooting
To troubleshoot Auto Path, you can use these troubleshooting tools:
• Event Viewer
The Event Viewer logs path failovers/recovery, disk and adapter
errors, and I/O errors.
• Windows Diagnostics
The Administrative Tools utility, accessed from the Windows Control
Panel, shows all devices connected to the Windows system.
• Windows Registry
Caution Back up the Registry before executing the Registry Editor.
The Registry shows the devices connected to the Windows system.
The Registry Editor can be used to display the devices seen at boot
time.
• Disk Administrator
Disk Administrator shows the paths that are online and offline. If all
the paths to a LUN appear to be offline, it is likely that the device is
not preformatted at the disk array level. Preformat the device, and the
Disk Administrator will see the path of the device and the remaining
paths offline.
