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.
Configuration options
Menu option | Description | SETSRM keywords | Action line commands | EZCmd menu |
|---|---|---|---|---|
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.
