Configuration

`When you select Configuration from the EZSRM menu, you advance to the Configuration menu options.

These options provide real-time configuration reports for the storage resources in your enterprise. Upon each of the following events and actions, MainView SRM rebuilds the configuration information to continue to reflect real-time data:

  • Issuing of the Config REFRESH command
  • Issuing of the z/OS VARY command
  • Refreshing MainView SRM pools or subpools
  • Noting of SMS configuration or volume status change

To access configuration information about storage resources, you first select a resource type, such as subsystems. From the resulting list of resources, you can drill down to an individual device, such as a specific SSID. Selecting a device produces a more detailed report about the device or accesses an EZCmd menu that provides additional configuration information options.

The following table summarizes each configuration option and its corresponding SETSRM keywords, action line commands, and EZCmd menus. See each corresponding section for a description of each option.

Note

For complete keyword descriptions for the SETSRM command, see SETSRM command.

You can press F1 in the CMD column to display online Help that describes each action line command.

Groups and Pools

Advances to the GPCNFG view.

This view provides you with real-time configuration information about all storage groups, subpools, and DASD pools in your enterprise. For each storage group and pool, GPCNFG summarizes information such as the number of volumes, number of offline volumes, volume counts by SMS status, and so on. Group EZMenu (EZPOOL) summarizes the views that you can access by issuing action line commands.

View GPCNFG displays a great deal of information. Review the following notes to clarify the data shown in specific columns. For more information about these and other columns, place your cursor on the column heading and press F1 for online Help.

  • Vols Dropped

    This column shows the number of volumes that have been dropped from the pool or subpool report information. The MainView SRM Reporting component supports volumes that are defined in a combination of up to eight pool and subpool combinations. Therefore, configuration information is not correct for pools and subpools from which volumes have been dropped.

    The MainView SRM Allocation component supports volumes that are defined in an infinite number of pools and subpools; therefore, it is not affected by the Vols Dropped count.

  • VSCAN DSNs and Current DSNs

    VSCAN DSNs shows the number of data sets on the VTOC scan master file for the group; therefore, it matches the number of data sets displayed in the associated Data Set Analysis views (described in Data set analysis). This count does not include data sets that reside on volumes that have been dropped from the pool because the volume is defined in more than eight pools and subpools combined.

    Current DSNs shows the number of data sets that are in the selected group. This value shows the total from the Current DSNs field on view VOLCNFG for each volume in the group.

    The difference between values in the Current DSNs column and the VScan DSNs column results from activity that has occurred on volumes in the group since they were last scanned. See the VScan DSN Date and VScan DSN Time columns to determine when a volume in the group was last scanned and updated to the VTOC scan master collection file.

Subsystems

Volumes

Advances to the VOLCNFG view.

This view displays real-time configuration information about all of the volumes in your enterprise. Review the following notes to clarify the data displayed in specific columns. For more information about these and other columns, see the online Help. To access Help for a column, place your cursor on the column heading and press F1.

  • Owning Pools

    The MainView SRM Reporting component allows a volume to be defined in as many as eight pools (which can be a combination of pools and subpools).

    The Owning Pools and the Volser columns are highlighted if the number of pools exceeds eight. See the Vols Dropped column on the GPCNFG view for help in determining the pools that are affected.

Boxes

Advances to the BOXCNFG view.

This view displays real-time configuration information about all RAID and non-RAID control units and devices in your enterprise, as follows:

  • Supported RAID devices as a single BOX that contains multiple physical disks with multiple volumes on each physical disk
  • Unsupported RAID devices as though they were non-RAID devices, which are displayed as independent 3990/3880 control units

None

Physical Disks

Advances to the PHYCNFG view.

This view displays real-time configuration information about all physical disks in your enterprise and the volume count and total cylinders for each. The following resources are considered physical disks:

  • A physical disk within an EMC Symmetrix device

    The physical-disk identifier is one of the following combinations:

    • Symmetrix serial number, director number, and SCSI identifier
    • Symmetrix serial number and thin pool name
    • Symmetrix serial number and SRP (Storage Resource Pool) name

    Note: For information about support of EMC devices, see the MainView SRM Customization Guide .

  • A drawer within an IBM RAMAC, RAMAC2, or RAMAC3 subsystem

    The physical disk identifier is the control unit serial number and the drawer number.

  • A rank within an IBM ESS device

    The physical disk identifier is the control unit serial number and the rank identifier.

  • An RVA/STK device

    The physical disk identifier is the control unit serial number. The entire box is treated as a single physical disk.

  • Non-RAID devices

    Non-RAID devices include independent 3990/3880 control units and RAID devices not supported by MainView SRM. The physical disk identifier is the control unit serial number. The entire box is treated as a single physical disk.

Note: To appear within MainView SRM views, a volume on a physical disk must be online to the local system. EMC physical disks are the exception. All EMC physical disks appear on PHYCNFG if any volume on the owning box is online to the local system. For information about support of EMC devices, see the Customizing MainView SRM products
