The show media health commands display the location, media ID, model, life
remaining, and status (or health) of media devices on the local HP VMA SAN
Gateway or on all of the HP VMA SAN Gateways in the cluster. The commands
can be used in Enable and Config modes.
Understanding Media Health Statuses
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 statuses 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.
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.)
