Table 2-4 Troubleshooting RAID Problems

Symptom
Some RAID drives do not
appear on the show device d
display.
Drives on the SWXCR
controller power up with the
amber Fault light on.
Cannot access disks connected
to the RAID subsystem on
Windows NT systems.
2–14 DIGITAL Server 3300/3300R
Action
Valid configured RAID logical drives will appear as
DRA0--DRAn, not as DKn. Configure the drives by
running the RAID Configuration Utility (RCU),
following the instructions provided with the
StorageWorks RAID array subsystem.
Reminder: several physical disks can be grouped as a
single logical DRAn device.
Whenever you move drives onto or off of the
controller, run the RAID Configuration Utility to set
up the drives and logical units. Follow the
instructions provided with the StorageWorks RAID
array subsystem.
On Windows NT systems, disks connected to the
controller must be spun up before they can be
accessed.
While running the ECU, verify that the controller is
set to spin up two disks every 6 seconds. This is the
default setting if you are using the default
configuration files for the controller. If the settings
are different, adjust them as needed.
