Unix tip: Finding a fault when your server's shut down

February 11, 2009, 02:26 PM — 

One of the most useful commands to run when you suspect a failing component on your Sun server is showboards. Showboards will display the status of all boards in your system. With the -ev arguments, the command will provide more complete information and also tell you about empty slots. The showboards -ev command will start with a display like that shown below. In this case, you can see that the PCI I/O Board has failed (look at the next to last line in the output below).

lom>showboards -ev

Slot     Pwr Component Type                 State      Status

/N0/MB   -   Media Bay                      Assigned   Passed 

This display will be followed by a series of additional tables. For example, the memory in the system might be display in a series of lines like those below that describe its configuration:

Component         J-No.   Size      Reason                                  
---------         -----   ----      ------                                  
/N0/SB0/P0/B0/D0  J13300  512 MB                                            
/N0/SB0/P0/B0/D1  J13400  512 MB

/N0/SB0/P0/B1     -       -         DRAM DIMM Group 1 Empty
...

Additional components will be listed as well. In these top few lines of the following table, we see another reference to the failed I/O board:

Where Google Chrome security fails: the password
I heard mention that the Chrome OS will have some sort of encryption available a la bitlocker. If it's possible to encrypt personal data using another password or key, then it may have potential for very secure data.... And Ubuntu has an 'encrypt home directory' option, perhaps google should follow suit.
