------- Comment From hbath...@in.ibm.com 2015-02-04 19:20 EDT------- Louis & Chris, thanks for your help. The packages work as intended in both kdump & fadump modes. Couple of observations though:
1. When doing load/unload twice in succession, echo throws an error root@lop831:~# kdump-config load * fadump registered successfully root@lop831:~# kdump-config load /usr/sbin/kdump-config: line 301: echo: write error: Invalid argument * fadump registered successfully root@lop831:~# -- root@lop831:~# kdump-config unload * fadump un-registered successfully root@lop831:~# kdump-config unload /usr/sbin/kdump-config: line 323: echo: write error: Invalid argument * fadump un-registered successfully root@lop831:~# 2. While using network dump (SSH), would be nice if we can warn the user to run 'kdump-config propagate' before 'kdump-config load', if /root/.ssh/kdump_id_rsa is missing. This applies to both kdump & fadump modes Thanks Hari -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1415562 Title: [Ubuntu 15.04] Support firmware assisted dump on ppc64le Status in linux package in Ubuntu: Fix Committed Status in makedumpfile package in Ubuntu: In Progress Bug description: Starting from POWER6, the firmware now has a capability to preserve the partition memory dump during system crash and boot into a fresh copy of the kernel with fully-reset system. This feature adds the necessary support to exploit the dump capture capability provided by Power firmware. With this feature support, the production kernel will register for firmware-assisted dump using RTAS (Runtime Abstraction Service) calls and builds required ELF header which then gets exported through '/proc/vmcore' in the second kernel after crash. This feature improves Power serviceability by making it more robust compared to current kdump mechanism on Linux. Ubuntu 15.04 kernel already includes the necessary code for fadump. The only kernel change needed is to enable CONFIG_FA_DUMP in the kernel configuration. In addition, an update is needed for a script in kdump-tools package.
