Hello all,

I'm trying to implement an HACMP cluster with a HDS 9570 storage array.
Levels are:
AIX 5.2 ML01
HACMP V5.1 PTF 1
HDLM 5.1-C

When a node crash, it can't release its LUN, and the second node can't
access to the VG.

At the LUN level (HDS config) there is a particular thing to do (disable
security or other) ???

Another gotchas ??

PS: 95XX series are not officialy supported by IBM/HACMP unlyke 99XX boxes

The newest HDLM drivers released some months ago supposedly fixes this
issue, i haven't tested them yet though.

There is no way to release the LUNS save for having a HDS technician
come do it onsite on the boxes! BTW - This is a driver issue which
means the 99xx boxes shares the problem :-(
