Managing Disk Arrays

The MAXX-2420-EX’s Disk Array Configuration Utility provides tools for monitoring and
managing the disk array. Monitoring and troubleshooting programs automatically check the
array, report problems and provide access to RAID status information and service options.
If up to two drive faults should occur, it should not cause data loss; but remember that the drive
array is degraded and no longer has fault tolerance. Hence, another disk failure will cause a
complete loss of data and system failure. After a drive failure it is strongly recommended that at
the earliest time diagnostics be performed.

Error Notification and Repair

The server will notify users in the event of a fault by flashing the front panel DRIVES light. A
flashing DRIVES light can be triggered by a variety of conditions. A failure condition will also be
indicated in the Image Server GUI in the status bar, on the bottom of the screen and highlighted
in yellow ( Figure 43 ). A GPIO Output can be programmed to activate upon a RAID or system
fault. This can be used to activate a warning lamp or alarm. Refer to Page 52 for more
information on programming GPIO events. A drive fault can be trigged by a variety of
conditions. The first step in response to an error warning is to open the RAID CHECK
STATUS

window from the On-Screen Start Menu. Click Start > RAID Status to launch the

RAID Array Configuration Utility.

Figure 43 - GUI Drive Fault Indication


The RAID Maintenance window (Figure 47, page 108) displays the current status of the RAID
controller and all disks connected to the RAID system. On inspection, you will find the array in
one of the following states:

OK, indicated by "OK" for Array Unit 0 and all Ports (drives);
Initializing, indicated by "Initializing" on the Array Unit 0 status line;
Degraded, indicated by "Degraded" on the Array Unit 0 status line;
Verifying, indicated by "Verifying x%" on the Array Unit 0 status line.
Rebuilding, indicated by "Rebuilding x%" on the Array Unit 0 status line.
