preffered path problem on FAStT 500

[arvibm]

Hi,

We have FAStT 500 with three enclosure(30 disks) connected between two aix servers.We have defined 4 arrays on FAStT500,3 OF THEM ARE ON raid-10 and 4rth is on RAID-5.The preffered path of one of the RAID-10 Array automatically changes to non-prffered path.Even after changing it manually to preffered path after some time it automatically changes to non-preffered path.I have checked for versions of RDAC Drivers installed on both the aix servers and the filset versions are as per the documenation.
Storage/Aix Guru's i need ur help to resolve this problem.

Regards

Hi,

The problem is resolved by upgrading fileset version of devices.pci.df1000f7.rte on one of the servers.
