# opagenesmchassis

Generates a list of chassis IPv4 and IPv6 addresses and/or TCP names where the Embedded Subnet Manager (ESM) is running, in a format acceptable for inclusion in the /etc/opa/esm_chassis file. This tool uses `opagenchassis` output to iterate through all the chassis.

## Syntax

    opagenesmchassis [-u user] [-S] [-t portsfile] [-p ports]

## Options

`--help`
  Produces full help text.
`-u user`
  Performs command as `user`. For chassis, the default is `admin`.
`-S`
  Securely prompts for password for user on chassis.
`-t portsfile`
  Specifies the file with a list of local HFI ports used to access fabric(s) for analysis. Default is /etc/opa/ports
`-p ports`

  Specifies the list of local HFI ports used to access fabrics.

  Default is first active port. The first HFI in the system is 1. The first port on an HFI is 1. Uses the format hfi:port, for example:
  `0:0`

    First active port in system.

  `0:y`

    Port `y` within system.

  `x:0`

    First active port on HFI `x`.

  `x:y`

    HFI `x`, port `y`.

## Environment Variables

The following environment variables are also used by this command:

Alternatively, while editing the file, use a `vi` command to include the output such as:
