Change Management Functions
A few change management commands are describe in this section. For complete
details of change management, refer to “Performing Change Management
Operations” in the Multiprotocol Access Services Software User’s Guide.
Describe Load Images
At
Boot config
>
, type describe 2216. The Product ID, microcode version number,
release number, maintenance number, PTF, Feature, and RPQ numbers and the
date of the operational software image are displayed.
Describe Config Images
At Boot config
>
, type describe config. For each configuration file that is loaded,
its bank, internal location (for example, CONFIG 1), version, and level is displayed.
Disable Dumping
The IBM 2216 can be set up to dump the contents of memory to permanent
storage in the unlikely event of a complete system failure. If dumping is enabled,
using this selection will cause the IBM 2216
not to dump to disk.
To disable dumping, type talk 6 or t 6 at the * prompt, press Enter, and then type
disable dump memory or dis dump at the
Config
>
prompt. You will see the
message:
System memory dump function disabled successfully.
Enable Dumping
This command enables the dumping of memory without intervention from anyone in
the event that the IBM 2216 has a catastrophic error. The IBM 2216 will dump
memory onto the hard disk. Once a successful dump has been taken, the IBM
2216 attempts to restart. Depending upon the failure of the IBM 2216, it cannot
always restart. In this case, you should restart it manually and call a service
person who will dial into the IBM 2216 to determine the nature and the causes of
the failure.
Before you can enable dumping, you must first enable system rebooting. To
enable system rebooting, enter the following commands at the
Config
>
prompt.
enable reboot-system
enable dump-memory
Finally, to enable dumping, type t 6 at the * prompt, press Enter, and then type
enable or ena at the
Config
>
prompt. You will see the message:
System memory function enabled successfully
The default state is to have dumping enabled.
Erase Files
The IBM 2216 has a DOS file system structure with user access files in the /sys0
and /sys1 banks. The contents of these banks are the operational software load
images and the configuration files. Note that the following rules apply to erasing
files from the IBM 2216:
¹
Image files that are not ACTIVE can be overwritten anytime
¹
ACTIVE image files cannot be erased
¹
ACTIVE configuration files cannot be erased
