UCSManagerでのSysRqの送信方法

[jiro.tobimasu]

UCS Managerにおいて、物理サーバ上のRed Hat Linuxが無応答になった際に、

SysRqを送信し、kernel Panicを発生させて情報取得をしたいと考えています。

UCS Managerにおける操作時に、物理サーバ上のRed Hat Linuxに対し、

SysRqを送信する方法はありますか？有る場合には方法を教えてください。

-------------------------------------------------------------

In the UCS Manager, when Red Hat Linux on the physical server becomes unresponsive,

I think it sends a SysRq, you want to get the information by generating a kernel Panic.

When operating in UCS Manager, for Red Hat Linux on the physical server,

Is there a way to send SysRq? Please tell me how in some cases.

==========================================

You can configure server for sysrq ( soft lock up )  and hardware NMI ( hard lock up )

## Sysrq

https://access.redhat.com/knowledge/solutions/2023

## Add these kernel parameters to /etc/sysctl.conf for hardware NMI

kernel.panic_on_unrecovered_nmi=1

kernel.unknown_nmi_panic=1

When server freezes

1)  Try sysrq key strokes to generate core dump

2)  If it is not responding to key strokes, generate hardware NMI interrupt from UCSM CLI

scope server x/y

diagnostic-interrupt

commit-buffer

From GUI
