Problem: Cannot Display the lom> Prompt Using the “#.” Escape
Sequence
Check whether the first character of the “#.” escape sequence has been changed (this
is a user-configurable value). To check the current value, type the following from the
Solaris prompt:
The information that this command displays includes the “serial escape character”.
If this is not “#”, then type the character that is currently specified and follow it
immediately with a dot.
Problem: OpenBoot PROM Initialization Aborts and the Server Will Not
Boot
If the OpenBoot PROM initialization sequence aborts and the message ‘NO
IDPROM’ is displayed when the operating system is attempting to read the serial
number and MAC address, then you are attempting to boot without a valid System
Configuration Card inserted. The System Configuration Card contains the serial
number, MAC address, and NVRAM settings for the server.
Problem: Card Not Recognised During Installation or Bootup
The Sun Fire V120 and Netra 120 servers are fitted with a System Configuration
Card. If the card moves during transit then the server will not be able to read the
card, and as a result will not boot.
If the System Configuration Card has moved during transit, follow the steps below
to make sure it is seated in the server correctly.
Note – The presence of the tie-wrap does not necessarily mean that the card is
correctly located in the reader.
1. Remove the front bezel by pushing on the clips at both ends until they release.
2. Press the System Configuration Card in as far as it will go.
3. Replace the bezel and continue installation.
For more information about the System Configuration Card, see Section 11.1,
“Replacing a Server” on page 11-2.
