Halt On Error
The Halt On Error function causes the FastTrak controller to stop the boot
process at the FastTrak BIOS screen when there is a problem with your logical
drive.
For example, a disk drive failure causes your logical drive to go critical.
Depending on the Halt On Error setting, one of the following events will happen:
• Enabled – Your system will stop booting at this point to alert you to the
condition. Press Ctrl-F to enter the FastBuild utility and diagnose the
problem.
• Disabled – Your system will continue booting. In this case, you could use
WebPAM to diagnose the problem.

System Resources
The information in the System Resources section might be helpful for
troubleshooting purposes:
• Installed memory address and size
• The system IRQ used by the FastTrak card
• Base Addresses (advanced troubleshooting)
Logical Drive Problems
While disk drives are highly reliable, on occasion a disk drive can fail. Fault-
tolerant (RAID 1, 5, 10 and 50) logical drives go Critical when a disk drive fails.
Non-fault-tolerant logical drives (RAID 0) and JBOD go Offline when a disk drive
fails.
When a fault-tolerant logical drive goes Critical, one of two things must happen in
order to restore the logical drive to Functional status:
If a hot spare drive is available, the FastTrak Controller will automatically begin
rebuilding the logical drive with the hot spare. You must replace the failed drive,
which becomes the new hot spare.
If a hot spare drive is not available, you must replace the failed drive, after which
the FastTrak controller will automatically rebuild the logical drive.
For more information about hot spare drives, see page 45.
In either case, you must identify the failed drive so you can replace it. See the
example below.
