8.1.1.1 info subcommad

DESCRIPTION

The subcommand "info" displays the configuration information of the specified instance or all instances, and the status of the communication paths.
Instance refers to a unit of IOMP composition. Since there is only "/dev/FJSVhwr/fiomp/mse0" as the instance of the serial port for the console, omitting an instance name is equivalent to specifying it to this subcommand.

SYNOPSIS

/usr/opt/FJSViomp/bin/iompadm [-p] -c fjmse info [instance-name]

EXAMPLE

When -p option is not specified:

# /usr/opt/FJSViomp/bin/iompadm -c fjmse info /dev/FJSVhwr/fiomp/mse0
IOMP: /dev/FJSVhwr/fiomp/mse0
Element:
        /dev/fjse/0     online  active  block   ""
        /dev/fjse/1     online  standby block   ""
Node:
        /dev/FJSVhwr/mse/a
Function:
        MPmode=false
        AutoPath=true
        Block=true
        NeedSync=false

Specify the -p option:

# /usr/opt/FJSViomp/bin/iompadm -p -c fjmse info /dev/FJSVhwr/fiomp/mse0
IOMP: /dev/FJSVhwr/fiomp/mse0
Element:
        /dev/fjse/0     online  active  block   ""
-> /devices/pci@83,4000/ebus@1/FJSV,se@14, 400000:0,fjse
        /dev/fjse/1     online  standby block   ""
-> /devices/pci@87,4000/ebus@1/FJSV,se@14, 400000:1,fjse
Node:
        /dev/FJSVhwr/mse/a
Function:
        MPmode=false
        AutoPath=true
        Block=true
        NeedSync=false

"Table 8.2 Indication Synopsis" explains information output in the above examples.

[Table 8.2 Indication Synopsis]

Format	Description
IOMP: Instance Name	Identifies the IOMP Instance name.
Element: communication-path-name/status/details/access-permission ->physical-device-name (-p option)	Indicates information about the communication path that comprises the IOMP: communication path name, status, detailed status, and access permission. If the -p option is specified, a physical device name will be displayed.
Node: User-Access-Node	Identifies the configured IOMP device name available to users. "/dev/console" and user access node will be performed to access to the same device.
Function: MPmode={true|false} AutoPath={true|false} Block={true|false} NeedSync={true|false}	Indicates the IOMP features: MPmode: Simultaneous access to multiple paths AutoPath: Automatic path switching Block: Access control NeedSync: Synchronization of shared disk

The following describes the information listed in "Table 8.2 Indication Synopsis" in detail.

• status of communication path

online

The communication path is enabled to communicate.
In this case, "active" or "standby" is displayed as the detailed status.

offline

The communication path is disabled to communicate.
In this case, "stop" or "fail" is displayed as the detailed status.

unconfigured

The communication path is being detached by Dynamic Reconfiguration.
In this case, "disconnected" is displayed as the detailed status.

• detailed status

active

The communication path is enabled for communication or being used for communication.

standby

The communication path is ready for communication, but is in an idle state.

stop

The communication path is being stopped.

fail

The communication path is disabled for communication, caused by a failure.

disconnected

The communication path is being detached by Dynamic Reconfiguration.

• access permission

  The following information indicates whether incoming direct access to the communication path is permitted:

block

prohibited

unblock

permitted

• MPmode

  Indicates whether the communication path in the IOMP configuration is used at the same time. In the case of console, since only one communicating path is in an instance, "false" is displayed.

• AutoPath

  Indicates whether the communication path is switched automatically. In the case of console, "true" is displayed because the fjmse driver switches a communication path automatically.

• Block

  Indicates whether user direct access to the communication path is limited. In the case of console, since only the fjmse driver controls communication paths to prevent users access to them directly, "true" is displayed.

• NeedSync

  Indicates whether the fjmse driver needs to synchronize data of communication path. In the case of console, "false" is displayed.
