If you will execute commands by the in-band method to a command device on the storage system, specify the LU path for the command device in the configuration definition file. The command device in the storage system specified by the LU path accepts the commands from the client and executes the operation.
If you will execute commands by the out-of-band method, specify the virtual command device in the configuration definition file. The virtual command device is defined by the IP address of the SVP, GUM, ESM, or AMC, the UDP communication port number (fixed at 31001), and the storage system unit ID* in the configuration definition file. When a virtual command device is used, the command is transferred from the client or server via LAN to the virtual command device specified by the IP address of the SVP, and an operation instruction is assigned to the storage system.
* The storage system unit ID is required only for configurations with multiple storage systems.
The following examples show how a command device and a virtual command device are specified in the configuration definition file. For details, see the Command Control Interface User and Reference Guide.
Example of command device in configuration definition file (in-band method)
HORCM_CMD #dev_name dev_name dev_name \\.\CMD-64015:/dev/rdsk/*
Example of virtual command device in configuration definition file (out-of-band method with SVP)
Example for SVP IP address 192.168.1.100 and UDP communication port number 31001:
HORCM_CMD #dev_name dev_name dev_name \\.\IPCMD-192.168.1.100-31001
Example of virtual command device in configuration definition file (out-of-band method with GUM, ESM, or AMC)
Example for GUM, ESM, or AMC IP addresses 192.168.0.16, 192.168.0.17 and UDP communication port numbers 31001, 31002. In this case, enter the IP addresses without line feed (VSP One B85, VSP One B20 series, VSP E series, VSP G130, G/F350, G/F370, G/F700, G/F900, VSP G200, G400, G600, G800, and VSP F400, F600, F800).
HORCM_CMD #dev_name dev_name dev_name \\.\IPCMD-192.168.0.16-31001 \\.\IPCMD-192.168.0.17-31001 \\. \IPCMD-192.168.0.16-31002 \\.\IPCMD-192.168.0.17-31002
