Solaris Live Dump

To carry out a system dump on Solaris while the server is running:

  1. Create a filesystem with sufficient space , e.g. 2Gb for a server with 8Gb of memory

  2. Configure dump to use this filesystem: dumpadm -d filesystem (this can be checked using the dumpadm command)

  3. Run savecore -L

A crash dump will be created under /var/adm/crash
