IPMI interface for fencing - RH fence agent for the Superdome blades -

[A.W.R]

Hi,

We are configuring a RedHat Linux cluster between 2 Superdome X Blades. We have been advised that we will require an IPMI interface for fencing . Is there a specific RH fence agent for the Superdome blades ?, Or do we use the native one?

Appreciate any input.

Kind Regards

Basically, any method or agent which can cutt off the shared storage access from a failed node would be a valid choice for fencing. A failed node would get removed from access to shared storage either by doing hard fencing which is nothing but powering off the node or by doing a soft fencing which normally triggers cut off to storage device only but system remains on. There is "fence_hpblade" available for RHEL6.4 and later versions [https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/Fence_Configuration_Guide/index.html#tb-software-fence-hpblade-CA]

A good introduction to fencing is here [https://access.redhat.com/solutions/15575]
