We´ve to install Oracle 10gR2 RAC ( on Os solaris 5.10 with fujitsu siemens primecluster version SMAWcf-4.2A0025EKS03.

We have to place the Oracle Cluster Repository (OCR) and the Voting Disk on shared devices. We´re using NFS - files on a NetworkAppliance filer (model FAS250, Version 7.0.3P4.

All NFS - files are mounted with following options:
rw,bg,hard,intr,rsize=32768,wsize=32768,proto=tcp, forcedirectio,noac,timeo=180,vers=3

We decided to place OCR and CSS on a shared nfs file: na:/vol/oracle/data1:
OCR = /nfs/oracle/data1/oracrs/OCR
CSS = /nfs/oracle/data1/oracrs/CSS

During installation of oracle clusterware with OUI occurs the following problem:

Executing configuration script orainstRoot.sh on node1 = OK

Executing configuration script root.sh on node1 FAILED: Failed to upgrade Oracle Cluster Registry configuration.

What´s the possible reason for this failure ? What can we do to solve this problem ?

Thank you for your help in this matter !
