Reason:
Setting the sysparm CARTCALC to the value N or allowing it to use the default value N, turns off the query to the device for the device capacity. This causes the value in the sysparm CARTFEET to be used to set the cartridge capacity. Having sysparm CARTCALC set to N can cause under-utilization of tape cartridges. It may also cause unnecessary I/Os to be performed on a tape if the calculated capacity is greater than the actual capacity, because an attempt may be made to fit a data set that is too large for the remaining tape space by wasting time and resources. This exception will be cleared when this check runs again after the job causing the exception is changed and runs, or after the job statistics are older than the number of days specified in the AGE parameter for this health check. The default value for the sysparm CARTCALC will be changed to Y with the next release of CA Disk.
Action:
Find out why the sysparm CARTCALC is set to N. Consider setting it to Y, if the sysparm has been set to the default value N. Consider setting the sysparm CARTCALC to Y and setting sysparm CARTPRCT to a value other than 100%, if the objective is to force CA Disk to either over or under utilize the tape cartridges.
