Managing the AMASS File System

IBM

Step 1.

When the AIX operating system was installed, a

 

 

dump device is automatically configured. The

 

 

default on most models is /dev/hd7.

 

Step 2.

When the system panics, it automatically dumps

 

 

information to the core file and the LEDs on the

 

 

front of the processor display “0c9.”

 

Step 3.

After information has been dumped, the LEDs flash

 

 

“888.”

 

 

For additional information on system-initiated

 

 

dumps, refer to the IBM Problem Solving Guide and

 

 

Reference manual.

Step 1.

Create a directory called /dir where the core files

 

 

can reside. Make sure there is plenty of disk space to

 

 

contain this directory because the size of the dump

 

 

depends on the amount of memory in the system and

 

 

can be quite large.

 

Step 2.

Modify the system startup file with a call to

 

 

savecore as described for the appropriate

 

 

operating system below:
