savecore { [ -c ] [ -d ] [ -f ] } DirectoryName SystemName
The function of the savecore command is to save a system dump and is usually run at system startup.
The savecore command checks to see that you have a recent dump and that there is enough space to save it. The system dump is saved in the DirectoryName/vmcore.n file, and the system is saved in the DirectoryName/vmunix.n file. The n variable is specified in the DirectoryName/bounds file. If this file does not exist, it is created with a default of 0, and the n variable uses this value. With each subsequent dump, the n variable is increased by 1.
If the system dump was from a system other than /unix, the name of the system must be supplied as SystemName.
Note: The savecore command saves only the current dump and the dump prior to the current one.
-c | Marks the dump invalid (not recent), but does not copy it. |
-d | Copies only the dump. It does not copy the system. |
-f | Copies the dump even if it appears to be invalid. |
