[jeffthc]

I have configed Antemeta on AIX5.3 ML03 by using EVA5000. Its working fine until someday it return me some error messages.

lspath output showed failed:

after that, the disk was crashed and I have to restore all the data. It happens few times already in pass 2 months. I would like to download latest driver from
http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?〈=en&cc=us&prodTypeId=18964&prodSeriesId=434395〈=en&cc=us
but nothing can be found from it.

Do you guys have any idea about this problem? and please tell me where I can download the drivers or patches. I am using:
devices.fcp.hdi.pdisk.rte 2.2.2.0 COMMITTED Antemeta pseudo subsystem disk support for IBM FC AIX 5.3

Thanks alot.
