Re: [suse-oracle] SLES11 and RAC 10.2

Hi,
   I was wondering if anyone has had a chance to run Oracle 10g (10.2)  
RAC on SLES11?
   Has anyone run into any sort of IO related problems?

   We've  run into some issues with fdisk and partitioning luns .. got  
around that with cfdisk, but now we are running
   into a few issues restoring a standby database and I'm concerned it  
could be because of the original weirdness we saw with fdisk.
   We've always used fdisk in the past with SLES10,SLES9, but the luns  
were always less than 1TB. Now the luns are about 1.8TB each.

   thank you.
