Chapter 3: Operating the Storage System
Checking CHALLENGE RAID Storage System Status
To check storage system status, you may find it easiest to look at the storage
system cabinet to see if the amber service light is lit.
Look for two lights at the right of the disk modules (deskside storage
system) or above the disk modules (chassis in rack). The green light indicates
whether the unit is powered on; the amber light indicates a fault. See
Figure 3-1.

CHALLENGE RAID Indicator Lights
The amber service light comes on when
•
an SP is reseated
•
the CHALLENGE RAID is powered off and on
•
the battery backup unit has not finished recharging (if battery backup
unit is present in the system)
If the service light is lit, look for a disk-module fault light that is lit. Then you
can either explore status further using the raid5 command in an IRIX shell,
as explained in this section:
•
using the raid5 command
•
getting the device name with getagent
