Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

ProcedureHow to Set Terminal Concentrator Port Parameters

This procedure explains how to determine if the port type variable must be set and how to set this variable.

The port type parameter must be set to dial_in. If the parameter is set to hardwired, the cluster console might be unable to detect when a port is already in use.

  1. Locate the Sun serial number label on the top panel of the terminal concentrator (Figure 2–7).

  2. Check if the serial number is in the lower serial-number range. The serial number consists of 7 digits, followed by a dash and 10 more digits.

    • If the numbers after the dash start with 9520 or higher, the port type variable is set correctly. Go to Step 4.

    • If the numbers after the dash start with 9519 or lower, you must change the port type variable. Go to Step 3.

  3. Use the administrative console to change the port type variable to dial_in by setting the port parameters, then reboot the terminal concentrator as shown in the following example.

    The boot command causes the changes to take effect. The terminal concentrator is unavailable for approximately one minute.

    admin-ws# telnet tc_name

    (The default password is the terminal concentrator IP address)
    annex# admin
    Annex administration MICRO-XL-UX R7.0.1, 8 ports
    admin : set port=1-8 type dial_in imask_7bits Y
      You may need to reset the appropriate port, Annex subsystem or
            reboot the Annex for changes to take effect.
    admin : set port=1-8 mode slave
    admin : quit
    annex# boot
    bootfile:  <return>
    warning:   <return>

    Note –

    Ensure that the terminal concentrator is powered on and has completed the boot process before you proceed.

  4. Verify that you can log in from the administrative console to the consoles of each node.
