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

Smart Method of Enable

C:ID:L Device Exceptions(MRIE) Control Enabled Count

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

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.
