Before you begin

Before you initiate a VTOC scan, update the following parameters in your SMMSYSxx member to conform to your shop standards:

Parameter	Default	Description
VSCAN_OINDX=	BMC AMI Ops	Specifies the prefix name of the VTOC Scan collection data set
VSCAN_OUNIT=	SYSALLDA	Specifies the direct access device type of the VTOC Scan collection data set
VSCAN_OVOL=	None	Specifies the volume serial number of the VTOC Scan collection data set
VSCAN_OPRI=	50	Specifies the primary allocation size in cylinders for the VTOC Scan collection data set
VSCAN_OSEC=	50	Specifies the secondary allocation size in cylinders for the VTOC Scan collection data set
VSCAN_TUNIT=	SYSALLDA	Specifies the device type for the VTOC Scan temporary data set
VSCAN_TVOL=	None	Specifies the volume serial number for the VTOC Scan temporary data set
VSCAN_TPRI=	100	Specifies the primary allocation size in cylinders for the VTOC Scan temporary data set
VSCAN_TSEC=	50	Specifies the secondary allocation size in cylinders for the VTOC Scan temporary data

Important

Once initiated, the VSCAN command runs to completion. The only way to stop VSCAN is to initiate a shutdown of the entire SVOS address space.

To initiate a VTOC scan

Type the following command, where svosstc is the name of your SVOS address space:/F svosstc ,SVOS VSCAN,SUF=IV
This command initiates a VTOC Scan using the filter member SMVSCFIV (suffix IV). Filter member SMVSCFIV specifies to scan the IVPPOOL volumes and update the VTOC Scan master collection data set.
The data set name that contains the scan output is indicated in a message that appears in the SVOS job log in response to this command.
Under DASD Analysis on the EZSRM Menu, select Data Set Management to advance to the Data Set Management menu.
Under Data Set Aging, select Age Distribution to access a pop-up menu.
Select by HLQ to advance to the DSSRAD view, which shows all high-level qualifiers for data sets on the volumes in the IVPPOOL. A summary of data set ages is given for each HLQ.
Select a number in the Age 1 DSNs column to see the data sets that have the high-level qualifier in the first age range.Age-range values are specified in SMMSYSxx VSCAN_AGEx keywords. If these keywords were not specified, all data sets appear in AGE RANGE 1. If all data sets appear, consider taking the following steps:
1. Add the VSCAN_AGEx keywords to SMMSYSxx. For example, VSCAN_AGER1=1VSCAN_AGER2=7 VSCAN_AGER3=14You can define up to nine ranges.
2. Refresh the SMMSYSxx member.
3. Reissue the VSCAN command.
