Managing Disk Arrays
The server’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.
A single drive fault should not cause data loss; but remember: the drive array is degraded and
no longer has storage redundancy. Hence, another disk failure may 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, and the server be taken off line while the RAID array is rebuilt.
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 as shown below. 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 51
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 > System > RAID Status
to
launch the Array Configuration Utility.
Figure 39 – GUI Drive Fault Indication
The
RAID Maintenance
window (Figure 43, page 107) 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.
