Verification of hardware configuration

摘要

A method for verifying an input/output (I/O) hardware configuration is provided. Data from an input/output data set (IOCDS) is extracted for building a verification command. The IOCDS contains hardware requirements that define at least software devices associated with a logical control unit (LCU). The verification command is processed. The verification command includes a software device address range associated with a logical control unit (LCU) of the I/O hardware. The LCU utilizes a first logical path. The software device address range utilizing the first logical path is compared with an existing software device address range utilizing at least one additional logical path. The verification command is accepted if the software device address range and the existing software device address range match.

1. A method for verifying an input/output (I/O) hardware configuration, comprising:
starting an initial program load (IPL) and sending an establish logical path (ELP) command; verifying the ELP is for a logical control unit (LCU); extracting data from an input/output configuration data set (IOCDS) for building a verification command, the IOCDS containing a plurality of hardware requirements that define at least a plurality of software devices associated with the LCU, a collection of characteristics for each of the plurality of software devices, and an indication as to whether one of the plurality of software devices is one of off-line and online at the IPL; processing the verification command including a software device address range associated with the LCU of the I/O hardware configuration, the LCU utilizing a first logical path; and comparing the software device address range utilizing the first logical path to the LCU with an existing software device address range utilizing at least one additional logical path to the LCU and verifying the first logical path is established for the LCU.
