Host-Discovered Array Structure - HP XP P9500 Reference Manual

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
Example of CUxx:
If 11 1 1 is set to CCAMap of CU=05, the value for CU05.CCAMap is
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
(page 328).
Table 142 (page 329)
Host-Discovered Array structure is one of the following:
When the YKLOAD command is used for creating the structure:
stem-name-specified-in-STEM-parameter and dad-id
When the YKSCAN command is used for creating the structure:
stem-name-specified-in-opSTEM-parameter Each REXX variable is preceded by a period (.).
