We have a linux guest that frequently encounters a kernel panic, effectively killing the box. Thankfully, we have IBM Operations Manager and can trap the HCP message and instantly reboot the box once it hits the disabled wait state. We are running the latest RHEL4 maintenance on this guest and would like to provide a dump to RedHat. How can we trigger/capture a dump when the kernel panics?
Below is the console log for this guest at the time of the panic: 07/30/2007 05:49:55 kernel BUG at mm/filemap.c:2245! 07/30/2007 05:49:55 illegal operation: 0001 Ý#1¨ 07/30/2007 05:49:55 CPU: 1 Not tainted 07/30/2007 05:49:55 Process chmod (pid: 15271, task: 000000005b94ccb0, ksp: 000000005eb1beb8) 07/30/2007 05:49:55 Krnl PSW : 0700000180000000 000000000006cf98 (generic_file_aio_write+0x60/0x134 07/30/2007 05:49:55 07/30/2007 05:49:55 Ý<000000000002ff7e>¨ sysc_noemu+0x10/0x16 07/30/2007 05:49:55 Ý<00000200000c0700>¨ 0x200000c0700 07/30/2007 05:49:55 07/30/2007 05:49:55 <0>Kernel panic - not syncing: Fatal exception: panic_on_oops 07/30/2007 05:49:55 00: HCPGSP2629I The virtual machine is placed in CP mode due to a SIGP stop from CPU 01. 07/30/2007 05:49:55 01: HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 00018A66 07/30/2007 05:49:55 CP SEND TPC3675 IPL CMS PARM AUTOCR Thanks, Kevin Morris LexisNexis, a division of Reed Elsevier Inc. z/OS System Engineering ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
