Chapter 6. Maintaining and Administrating Red Hat Enterprise Virtualization Hypervisors
6.1. Enabling kdumps
/datapartition of the storage on the RHEV Hypervisor host. When installing a RHEV Hypervisor host, ensure there is sufficient persistent storage space for kdump files. The size of the kdump file is proportional to the amount of RAM installed on the host. For a system with 32GB of RAM, a Hypervisor requires a
/datapartition of at least 32GB plus additional space for RHEV specific data (approximately 512MB).
- Access a Linux, UNIX, or similar operating system with SSH and the
scpcommand installed. The
scpcommand has the following format:
- This example copies all kdump files to the
/tmp/RHEVkdumpsdirectory on the local system. Use the administrator (root) username and password configured during RHEV Hypervisor installation. Replace the example hostname,
rhevh.example.com, with a valid IP address or hostname for the RHEV Hypervisor.
$ scp -r root@
- Once this procedure completes you can delete all the original kdump files on the Hypervisor. Log into the Hypervisor as root and execute the following.
# rm -rf /data/core/*
