How should the crashkernel parameter be configured for using kdump on HPE DL384 Gen12?
Environment
- Red Hat Enterprise Linux (RHEL) 9.4
- Hewlett Packard Enterprise (HPE) ProLiant DL384 Gen12
Issue
The HPE DL384 Gen12, an NVIDIA Grace Hopper-based server, failed to generate the vmcore both locally and over NFS when running kdump
Resolution
To successfully generate the vmcore locally or over NFS when running kdump, a specific crashkernel value of 'crashkernel=2G' needs to be manually configured, rather than using the default setting of 'crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M'.
