- Problem Statement: 

How are multiple blacklist files interpreted?

- Symptoms:

N/A
              

- Troubleshooting:

There can be several blacklist files that affect the platform:
 
1.  platform-wide blacklist files and domain-specific blacklist files.

2.  ASR (Automatic System Recovery) blacklist file

3.  .postrc blacklist files

There are cases where multiple blacklist files get concatenated, and there are other
cases where only a single backlist file is used.

- Resolution:

A blacklist file is a text file which lists specific hardware resources to be
considered unusable by POST. Blacklisted components will not be probed for, tested
or configured.

The backlist file will most often be empty. It is not required to exist.

POST supports two canonical blacklist files. These
files are considered logically concatenated.  If
both files exist, both files will be read and used.

1. A platform blacklist file:
   $SMSETC/config/platform/blacklist
2. A domain specific blacklist file:
   $SMSETC/config/[A..R]/blacklist  -  [A..R] is the domain ID

The default blacklist locations can be overridden from the
hpost command line (-P) or with a .postrc directive.
When this is done, only the specified blacklist file is read.

The reserved word "none" can also be used and causes no blacklist
file to be read.

There is also an ASR (Automatic System Recovery) blacklist file.
$SMSETC/config/asr/blackist
The ASR blacklist file is populated by the esmd daemon when it
detects a failing component.
The system can be instructed not to use the ASR blacklist file
by using the 'no_asr_blacklist' .postrc directive.

Hand editing the blacklist file is discouraged.
The disablecomponent command will populate the blacklist file for you.

Examples:

disablecomponent sb2/p0  -  Will disable sb2/p0 in the platform blacklist.

disablecomponent -d a sb2/p0 - Will disable sb2/p0 in the domain A blacklist
