Error Threshold for Drives
A new limit for driver errors can be set. Once the limit is reached, the drive is removed
from any redundant sets to which it belongs and put into the failed set.
Errors counted are medium and recovered errors - there is no need to add hardware
errors to this count as the drive fails immediately if a hardware error is encountered.
A set of CLI commands is provided that sets the threshold value and resets the error
counters for the drives. This is needed due to the persistent nature of these counters.
Since the layered application parsing of the CLI output should not be disturbed, a
separate SHOW command is included to see the threshold value.
CLI Syntax
CLEAR_ERRORS DRIVE_ERRORS
Enter the DRIVE_ERRORS command exactly and completely. This command clears
the error count, from non-volatile memory, for all devices on the system, setting each
to a value of 0. The current value of a devices error count is seen through VTDPY.
SET DRIVE_ERROR_THRESHOLD=<value>
Enter the DRIVE_ERROR_THRESHOLD command exactly and completely. This
command sets the threshold error to a value that determines when a drive will be
removed and placed in the FAILEDSET. The options for the command are any
number ranging from 0 to 999 with a value 0 shutting off the functionality. The user
can also input DEFAULT to receive the default error threshold of 700. The entered
value is placed into Non-Volatile memory and as such is persistent through failovers
and reboots.
SHOW DRIVE_ERROR_THRESHOLD
This command shows the current value of the drive error threshold for the controller.
The output is as follows
Drive Error Threshold: <value>
