sysdumpstart Command
Purpose
Provides a command line interface to start a kernel
dump to the primary or secondary dump device.
Syntax
sysdumpstart { -p | -s [ -f ] }
Description
The sysdumpstart command provides
a command line interface to start a kernel dump to the primary or secondary
dump device. When the dump completes, the system halts. Use the crash command to examine a kernel dump. Use the sysdumpdev command to reassign the dump device.
During a kernel dump, the following values can be displayed
on the three-digit terminal display as follows:
0c0 |
Indicates that the dump completed successfully. |
0c1 |
Indicates that an I/O occurred during the dump. This value only applies
to AIX 4.2.1 or later. |
0c2 |
Indicates that the dump is in progress. |
0c4 |
Indicates that the dump is too small. |
0c5 |
Indicates a dump internal error . |
0c6 |
Prompts you to make the secondary dump device ready. This value
does not apply for AIX 4.2.1 or later. |
0c7 |
Indicates that the dump process is waiting for a response from the
remote host. |
0c8 |
Indicates that the dump was disabled. In this case, no dump device
was designated in the system configuration object for dump devices. The sysdumpstart command halts, and the system continues running. |
0c9 |
Indicates that a dump is in progress. |
0cc |
Indicates that the system switched to the secondary dump device after
attempting a dump to the primary device. This value only applies to AIX 4.2.1
or later. |
You can use the Web-based System Manager Devices
application (wsm devices fast path) to run this command.
You could also use the System Management Interface Tool (SMIT) smit sysdumpstart fast path to run this command.
