ASM_LOCAL_SLOT_USAGE

Description:

Looks at the slot usage of each local page data set. The check generates an exception if the usage on any data set meets or exceeds the warning threshold.

Reason for check:

To maximize the efficiency of ASM slot management, you should keep the slot usage on all local page data sets below 30% .

z/OS® releases the check applies to:

z/OS V1R8 and later.

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change

Parameters accepted:

Yes, as follows:

When not using dynamicSEVERITY: THRESHOLD(value),
When using dynamicSEVERITY: THRESHOLD_HIGH(value), THRESHOLD_MED(value), THRESHOLD_LOW(value), THRESHOLD_NONE(value)
Note that the thresholds specified should increase in value as theSEVERITY increases, since a higher value indicates a more severe condition (higher usage of the paging data set), as shown in the following example:
```
PARM('THRESHOLD_HIGH(80%),THRESHOLD_MED(60%), THRESHOLD_LOW(30%)')
```

The variable for the parameters is as follows:

value: An integer, 0-100 indicating the warning threshold percent. It may optionally be followed by %.

Default: THRESHOLD(30%)

You can use synonyms for these parameters, as follows:

Parameter	Synonyms
THRESHOLD_HIGH	THRESHOLD_HI THRESHOLD_H
THRESHOLD_MED	THRESHOLD_M
THRESHOLD_LOW	THRESHOLD_L
THRESHOLD_NONE	THRESHOLD_NO THRESHOLD_N

PARM('THRESHOLD_HIGH(60%),THRESHOLD_MED(25%)')
