All other disk activity is suspended while identifying
devices.
View Drive Error Counters. A blinking star in the Device Status window
in the monitor utility screen indicates errors on the device. Use the Drive
Information selection to view the type and number of errors. The error
counters are for information only. The controller takes necessary actions to
recover from errors and to kill a device with too many errors.
Display Error Counter. Display the error counter window for a device by
pressing the Enter key. The error window displays error data only for SCSI
hard drives connected to the controller channel being monitored, and does
not display information for other types of SCSI devices.
The controller automatically recovers from the following errors:
Parity error: SCSI bus parity errors during transfer.
Soft error: Check condition/data errors from the disk.
Hard error: Channel hardware related errors.
Miscellaneous: Time out errors.
Use the cursor keys to select any of the drives and press the Enter key. The
Drive Error Counters window opens and displays the accumulated count of
all the different errors mentioned above. Press the spacebar key to clear the
error statistics for the selected device. This will start the device in its current
state. A warning message will display if there is a failure in clearing the error
counters.
After a power cycle (power off, then power on), all errors in the error counter
will be reset to zero.
Broadcast

users. When this option is selected, a dialogue box opens to allow a message
to be entered. Type the message in the box and press the Enter key to send it.
After the message is sent, the dialog box disappears and the main selection
menu returns.
