[Pacemaker] Software-only STONITH device

[cfk at itri.org.tw]

Hi Dejan,

Based on the information you provided, I also study the document of IBM RSA (http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-4ZVQKY ) and HP iLO (http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00553302/c00553302.pdf ). 
It seems that the minimum number of nodes required in a STONITH-enabled are 3. 

Thanks you for your help.

Hello,

I learned that IBMRSA architecture from http://www.opengear.com/SP-IBM.html.

Moreover, I also plan to study external/ipmi and ibmhmc at the same time. 

Assume I have a two-node cluster, and each node is equipped with more than one Ethernet interface.

Can I use external/ipmi and ibmhmc to set up a STONITH-enabled cluster? 

Are these connection internal independent (Ethernet interfaces of one node can't communicated with each other.) for out-of-band management (http://en.wikipedia.org/wiki/Out-of-band)?  

Thanks for your help again.

Ps: In IBMHMC redbook on http://publib-b.boulder.ibm.com/redbooks.nsf/RedbookAbstracts/SG247038.html, it seems that serial connection is still required if Figure 1-11 is referenced.

No. The closest is rcd_serial for which you need to build a
special serial cable. Otherwise, I strongly advise to obtain
either computers with some lights-out device (iLO or IBM RSA or
similar) or a PDU/UPS. Take a look here
http://www.clusterlabs.org/doc/crm_fencing.html for more
details.

Thanks,

Dejan
