A few warnings for folks running RHEL4/GFS on HP BL25p blades:

- update your firmware to the latest version on BL25p blades, or  
kernel 2.6.9-34.0.1smp (x86_64) will hang on boot (this is GFS/cluster  

- if you update one member of the cluster with the new fenced and  
reboot it (with other members being on with old fenced), once the new  
member comes back, others will go all weird and drop out of the  
cluster, followed by a panic on OOPS if you try to reboot them; the  
cluster won't work that way at all; best do them all at once (i.e.  
schedule downtime)

I found out the hard way... (i.e. nothing in fenced release notes about this).
