Hi Stefano, The instance names are now part of the ASM instance's profile, I assume the problem lies there. You can check the instance to node name mapping by viewing the profile. On my setup-four node RAC cluster with nodes rac11gr2drnode{1,2,3,4} I found this: $ crsctl stat res ora.asm -p NAME=ora.asm ... DEFAULT_TEMPLATE=PROPERTY(RESOURCE_CLASS=asm) ELEMENT(INSTANCE_NAME= %GEN_USR_OR A_INST_NAME%) ... DESCRIPTION=Oracle ASM resource ... GEN_USR_ORA_INST_NAME= GEN_USR_ORA_INST_NAME@SERVERNAME(rac11gr2drnode1)=+ASM1 GEN_USR_ORA_INST_NAME@SERVERNAME(rac11gr2drnode2)=+ASM2 GEN_USR_ORA_INST_NAME@SERVERNAME(rac11gr2drnode3)=+ASM3 GEN_USR_ORA_INST_NAME@SERVERNAME(rac11gr2drnode4)=+ASM4 ... The mapping is performed in these lines. I'm not sure if it's supported but you could try (on a test system!!!) to change the attribute GEN_USR_ORA_INST_NAME@SERVERNAME(<hostname>)=+ASMx for the hosts in question. You should probably involve oracle support, prompt them to give you their blessing and then go ahead after having taken manual OCR & OLR backups.
