lszdev must be modified to share the site-specific configuration information from the persistent settings. The persistent configuration array will be read and tabularized based on the site-id input from the user. This patch also accommodates the site specific information in the lszdev --info command. New information about the site-ids are integrated with the command. For example, DEVICE dasd-eckd 0.0.f001 Names : - Modules : dasd_eckd_mod dasd_mod Online : no Exists : yes Persistent : yes Sites : 1,2 ATTRIBUTE ACTIVE PERSISTENT SITE1 SITE2 cmb_enable "0" "0" "1" - eer_enabled "0" - - - erplog "0" - - - failfast "0" - - - last_known_reservation_state "none" - - - online "0" "1" "1" "1" raw_track_access "0" - - - readonly "0" - - - reservation_policy "ignore" - - - use_diag "0" - - - Each available site specific configuration will be shown as column. The "Sites" parameter in the above output indicates the available site configurations and the SITE1 and SITE2 colums indicates the detailed configuration for the respective sites.
