WebPAM User Manual

A non-fault tolerant logical drive—RAID 0—goes offline when a disk drive is

removed or fails. Since the logical drive is not fault tolerant, the data stored in the

disk array is no longer accessible.

If one disk drive fails, all of the data on the logical drive is lost. You must replace

the failed drive. Then, if the logical drive had more than one disk drive, delete the

logical drive and re-create it. Restore the data from a backup source.

When a Disk Drive Fails

The following will occur when a disk drive fails or goes offline:

• The FastTrak Controller’s audible alarm, if enabled, will sound

• The SuperSwap Status LED changes from green to red

• WebPAM reports the condition in Tree View, with popup messages and, if

Event Notification is set up, email messages

• If you have a RAID 1 or a 3-drive RAID 5 logical drive with a hot spare drive

properly configured, the logical drive will automatically rebuild itself using the

spare drive

In the example above, amber ! icons appear over the FastTrak, Controller,

Logical Drive View and Logical Drive icons. Click on the Logical Drive View or

Logical Drive icons to verify the condition of the logical drive.

In this example, the Status is Critical and Background activity is Idle. This

indicates that there is no automatic rebuild, so you must take action to restore the

logical drive:

1. Identify the failed disk drive.

2. Replace the failed disk drive.

3. Rebuild your logical drive.
