Hi If we are upgrading 10g Clusterware/ASM with 11g R2 Grid Infrastructure and if either it failed after asmca configuration or if we need to deinstall, what will happen to ASM Metadata. Can I able to start Oracle 10g clusterware /ASM by using Oracle Clusterware/ASM software along with OCR/Voting Disk and other cluster related files. TIA Sanjay
