Displaying and Enabling the MRIE Performance Setting

The MRIE performance enabled attribute indicates whether to

report exceptions according to the MRIE method, taking disk

performance into consideration. If you enable this feature,

S.M.A.R.T. reports exceptions if disk performance has not degraded;

otherwise, exception reporting stops.

The CLI allows you to do the following:

■ Display whether MRIE performance is enabled

■ Enable MRIE performance

To display the MRIE performance setting, use the disk show

smart command, as in the following example. In the example, the

Performance Enabled column contains an N for both devices,

indicating that devices (2,1,0) and (2,2,0) are not enabled for MRIE

performance.

HPN0> disk show smart

Executing: disk show smart

------ ------- ---------------- --------- ----------- ------

2:01:0 Y 6 Y N 0

2:02:0 Y 6 Y N 0

To enable S.M.A.R.T. MRIE performance, use the disk set smart

command with the /perf switch, as in the following example. The

example shows how to enable the MRIE performance feature on

SCSI device (2,1,0):

HPN0

disk set smart /perf=TRUE (2,1,0)

Executing: disk set smart /perf=TRUE (CHANNEL=2,ID=1,LUN=0)

SMART parameters on disk (2,01,0) were successfully set.

You can disable the performance feature setting the disk set

smart command’s /perf switch to FALSE. After enabling MRIE

performance, use the disk show smart command to verify the

MRIE performance setting.
