I believe at AIX 5.3 (maybe earlier) you no longer need HACMP in order to use GPFS. I think an easier way is to NFS mount it to the second lpar. Without doing something strange I don't think it would be possible to have the volume group active in read/write at same time to multiple, but if you did it with a JFS or JFS2 file system then you'd be risking corruption of it for sure.

Sent: Friday, June 15, 2007 1:41 PM To: [email protected] Subject: Quick AIX question rooted in a z/OS concept Hi all. I know this isn't a z/OS question but I don't think any of us live in a homogeneous environment and the best way I can think of asking this AIX question is to word it in z/OS terminology. I have an application developer who wants to have 2 AIX LPARs access shared disk. He thinks he can just have me point the LUN on the SAN to both LPARs and everything will work just fine. On my "Z", I can set up GRS or a third-party competitor to this to serialize I/O requests from various LPARs/machines. Is there something in AIX that performs a similar function? I asked this of an AIX list and the response I got back was something called GPFS which they say can do this. Unfortunately it appears as though I would need to buy and activate HACMP to use GPFS. Is there something else, more of a stand-alone product like GRS that would allow me to share a disk LUN across multiple AIX LPARs without having the LPARs step on each other? Thanks and have a happy Friday.
