Figure 34 – Web Monitor RAID Offline

You can access the Web monitor for more specific information on which RAID is offline. An example screenshot is shown in Figure 34.

If the RAID has multiple module failures, it will be taken offline. There will be a good chance your RAID will lose its data. Please contact Texas Memory Systems to diagnose and repair your system (see Section 4.15.1 – Contacting Texas Memory Systems).

Once the RAID has been repaired (probably by replacing failed Flash modules), it will have to be re-initialized.

WARNING

RE-INITIALIZING THE RAID WILL DESTROY ALL DATA ON THAT PARTICULAR RAID.

Right-mouse click on the offline RAID icon shown in the Web monitor and select “Initialize” to start the process, or you could just left- mouse click the green plus sign in the button bar. It will take roughly 20 minutes to finalize the initialization. The RAID will not be usable while it is being initialized.

5.4 Fans

The system has two fan trays, one behind the Flash modules containing eight smaller fans, and one in front of the RAM boards containing four larger fans. These fans cool components in the system. Internal sensors report the fan spin speed. If the fan-spin speed falls out of specification, warnings are reported. If they degrade and are unusable, errors are reported.
