Understanding Media Health Status
The status of the media device is defined by one of four values:
Status is determined for each individual S.M.A.R.T attribute by comparing its current normalized
value to a manufacturer-specified usage threshold. The
detail option lists all of the S.M.A.R.T
attributes and gives the status of each attribute. Without the
detail option, show media health
gives the worst-case status among all the device’s attributes.
Normalized values begin at their maximum (usually 100 or 254) and decrease with use of the
device, so they approach their specified thresholds from above. A warning status indicates that the
value is close to its threshold, and a critical status indicates that it has reached or passed the
threshold.
Note: Warning and critical status do not necessarily indicate any current problems; they only show
that devices are near the manufacturer’s thresholds for expected lifetime performance. When a
device reaches warning status, its detailed status should be monitored carefully.
Caution: Critical status indicates that failures are likely in the near future. It is recommended that
devices that reach critical status be disabled and replaced before they fail.
show media health
The
show media health command returns information about the health of storage media devices
on the local San Gateway.
To view information about storage media on other nodes in the cluster, use the
global option.
The show media health command returns information about the block storage media only. To
include non-storage media devices, use the
show media all health command.
ok
The device is running correctly and has plenty of expected life remaining.
unknown
The status cannot be determined.
warning A S.M.A.R.T attribute of the device is within 5% of the usage threshold
specified by the manufacturer.
critical
A S.M.A.R.T attribute is equal to or below its usage threshold. (This
indicates a high likelihood of impending failure.)
