Table 147 (page 328) shows the Host-Discovered Array Index structure. The prefix for the name of the Host-Discovered Array Index structure is one of the following: • When the YKLOAD command is used for creating the structure: HCC.HDA. • When the YKSCAN command is used for creating the structure: stem-name-specified-in-ARRAYS-parameter Each REXX variable is preceded by a period (.). Table 147 Host-discovered Array Index Structure REXX variables Description 0 n1 SerialNum Number of storage systems (number of n) Serial number of a scanned storage system DADID Device Address Domain ID Prefix Value specified to stem-name for Host-Discovered Array structure, excluding the trailing period. CUMap CUxx2 CCAMap Map information acquired from CU number Map information acquired from CCA CDEVMap Command device map information 1 Created for each SN (storage system serial number), thus index information for each device connected to the host is created. 2 Created for each CU, thus the device index information is created for each defined CU (CU number). The xx in CUxx is a hexadecimal value. Example of CUMap: For CUMap, 1 is assigned to the area that conforms to the CU number. When defined CU number is 00, 01, 03, and 05, the value for CUMap is 11 1 1. Example of CCAMap: For CCAMap, 1 is assigned to the area that conforms to the CCA. When defined CCA is 01, 02, 05, and 06, the value for CCAMap is 11 1 1. Example of CUxx: If 11 1 1 is set to CCAMap of CU=05, the value for CU05.CCAMap is 11 1 1. stem-name is fixed so that the YKLOAD command and the YKSTORE command can access the structure. Host-discovered Array Structure The Host-Discovered Array structure is created by using one of the following methods: • Executing the YKLOAD command to load copy groups, so that the disk configuration definition file will be converted to the Host-Discovered Array structure. • Executing the YKSCAN command, so that the scanned information will be converted to the Host-Discovered Array structure with a prefix specified in the STEM parameter. The YKSTORE command saves the Host-Discovered Array structure to the configuration file. NOTE: You can use the YKDROP command to drop the REXX variables in any Host-Discovered Array Structure that was loaded by using the YKLOAD command. The information in the Host-Discovered Array Index structure is used for referring to the Host-Discovered Array structure. For the structure, see "Host-discovered Array Index Structure" (page 327). 328 Data Objects
