HORCM_CMD (out-of-band method)

For the out-of-band method, a virtual command device is used instead of a command device. By specifying the location of the virtual command device in HORCM_CMD, you can create a virtual command device.

The location where the virtual command device can be created is different according to the type of the storage system. For details about locations, see the section System configuration using CCI in the Command Control Interface User and Reference Guide.

Tip: When you specify a virtual command device, you can enter a maximum of 511 characters for each line.

Create a virtual command device on an SVP (VSP, HUS VM, VSP G1x00, VSP F1500, VSP 5000 series, and VSP One Block 85)

Specify the following to HORCM_CMD of the configuration definition file:

\\.\IPCMD-<SVP IP address>-<UDP communication port number>[-unit ID]

<SVP IP address>: Specifies an IPv4 address of the SVP. Specifying an IPv6 address is not supported.
<UDP communication port number>: Sets the UDP communication port number. This value (31001) is fixed.
[-unit ID]: Sets the unit ID of the storage system for the multiple units connection configuration. This can be omitted.

Create a virtual command device on a GUM, ESM, or AMC (VSP One Block 85, 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)

Specify the following to HORCM_CMD of the configuration definition file:

\\.\IPCMD-<GUM, ESM, or AMC IP address>-<UDP communication port number>[-unit ID]

<GUM, ESM, or AMC IP address>: Specifies an IPv4 address of GUM, ESM, or AMC. Specifying an IPv6 address is not supported. To specify the IPv4 address of ESM or AMC, specify an IP address of each controller. Do not specify a service IP address of ESM or AMC.
<UDP communication port number>: Sets the UDP communication port number. These values (31001 and 31002) are fixed.
[-unit ID]: Sets the unit ID of the storage system for the multiple units connection configuration. This can be omitted.
Note: To use GUM, ESM, or AMC, we recommend that you set the combination of all GUM, ESM, or AMC IP addresses in the storage system and the UDP communication port numbers by an alternate command device configuration. See the following examples for how to set the combination.

Use a CCI server port as a virtual command device

Specify the following in HORCM_CMD of the configuration definition file:

\\.\IPCMD-<CCI server IP address>-<CCI port number>[-Unit ID]

<CCI server IP address>: Sets the IP address of the CCI server. Either an IPv4 address or an IPv6 address can be specified.
<CCI port number>: Sets the CCI port number. Specify the port number defined in HORCM_MON in the configuration definition file of the instance running on the CCI server. If HORCM_MON is not defined in the configuration definition file, the following CCI port numbers are specified:
- When the instance number is available: a port number that is the instance number plus 31001 is specified.
- When no instance numbers are available: a port number of 31000 is specified.
[-Unit ID]: Sets the unit ID of the storage system for the multiple units connection configuration. This can be omitted.

Examples

This example shows the case of IPv4.

HORCM_CMD
#dev_name dev_name dev_name 
\\.\IPCMD-158.214.135.113-31001

This example shows the case of IPv6.

HORCM_CMD
#dev_name dev_name dev_name 
\\.\IPCMD-fe80::209:6bff:febe:3c17-31001

This example shows the case when both the in-band and out-band methods are used:

HORCM_CMD
#dev_name dev_name dev_name
\\.\CMD-64015:/dev/rdsk/*  \\.\IPCMD-158.214.135.113-31001

This example shows the case when both the in-band and out-band methods are used in an alternate command device configuration:

HORCM_CMD
#dev_name dev_name
\\.\CMD-64015:/dev/rdsk/*  \\.\IPCMD-158.214.135.113-31001
HORCM_CMD
#dev_name dev_name
\\.\IPCMD-158.214.135.113-31001  \\.\CMD-64015:/dev/rdsk/*

This example shows the case of virtual command devices in a cascade configuration (three units):

HORCM_CMD
#dev_name dev_name dev_name
\\.\IPCMD-158.214.135.113-31001
\\.\IPCMD-158.214.135.114-31001
\\.\IPCMD-158.214.135.115-31001

(VSP One Block 85, 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) This example shows the case of alternate command device configuration of the combination of all GUM, ESM, or AMC IP addresses in the storage system and the UDP communication port numbers. In this case, enter the IP addresses without a line feed.

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

An IP address and a port number can be expressed using a host name and a service name.
