Use the PRTMEDBRM TYPE(*THRESHOLD) command to produce the Media Volume
Threshold report. The Media Volume Threshold report compares actual volume
threshold information against standard threshold information to alert you
to any potential errors in your media. Each media class is evaluated separately
with summary statistics at the end of each report. You have the option of
printing only exceptions, or all volumes with exceptions.
The following should be noted about this report:
Read, write, and usage error thresholds are numbers that you should obtain
from media manufacturers. The thresholds will vary widely between media classes.
BRMS also keeps the last cleaning date and the number of uses since
the volume was cleaned.
The "*" to the right of the Expiration date field indicates that the volume has expired. The "E" indicates
the volume is in error status and the 'I' indicates the volume requires
initialization.
The Exception detail field indicates the type
of (if any) exception which has occurred. These are listed below the listed
volumes for the media class. Possible values are:
*1 - No media class found for volume.
*2 - Media has exceeded use count.
*3 - Read error threshold has been exceeded.
*4 - Write error has been exceeded.
*6 - Reorder point has been reached for this class.
