Chapter 3 CLI Commands

(config) disk error-handling

To configure how disk errors are handled and to define a disk error-handling threshold on a WAAS

device, use the disk error-handling global configuration command. To return to the default

error-handling threshold, use the no form of this command.

disk error-handling {reload | remap | threshold number}

no disk error-handling {reload | remap | threshold number}

Syntax Description

Defaults error-handling threshold number: 10

Command Modes global configuration

Device Modes application-accelerator

central-manager

Usage Guidelines To change the default threshold, use the disk error-handling threshold global configuration command.

Specify 0 if you never want the disk drive to be marked as bad.

If the specified threshold is exceeded, the WAAS device either records this event or reboots. If the bad

disk drive is a critical disk drive, and the automatic reload feature (disk error-handling reload

command) is enabled, then the WAAS software marks the disk drive as bad, and the WAAS device is

automatically reloaded. After the WAAS device is reloaded, a syslog message and an SNMP trap are

generated.

By default, the automatic reload feature is disabled on a WAAS device. To enable the automatic reload

feature, use the disk error-handling reload global configuration command. After enabling the

automatic reload feature, use the no disk error-handling reload global configuration command to

disable it.

Examples The following example shows how to configure five disk drive errors for a particular disk drive (for

example, disk00) as the maximum number of errors allowed before the disk drive is automatically

marked as bad:

WAE(config)# disk error-handling threshold 5

reload Reloads the disk if the system file system (SYSFS) on disk00 has problems.

remap Sets the disk to attempt to remap disk errors automatically.

threshold number Sets the number of disk errors allowed before the disk is marked as bad

(0–100). The default is 10. A value of zero indicates that the disk should

never be marked as bad.
