Re: New ASM diskgroups not registered as a service in Grid Infrastructure

Martin,
You are right its early in the morning its ASM_DIskgroups not asm_diskstring i believe once you create the database that uses the new diskgroup if using dbca it should automatically add the resources if using manually you will need to add the database using srvctl and the discovery process will create the dependencies

Hi Fuad,

we are talking about GI 11gR2 here.

Usually, each existing diskgroup is represented as, for example, a GI service ora.ORADATA.dg. On 6 of my other systems, it works this way. This entry is created, as soon as I create the DG with asmca or SQL*PLUS.

But on this particular box, it does not work this way, instead, the new DG is added to ASM_DISKGROUPS parameter. But I want to install a 11gR2 database, which has to establish dependencies to diskgroups. Obviously, I have continous problems with such an incomplete setup.

IMO, the ASM_DISKSTRING parameter is the pattern for scanning devices, not managing diskgroups.

Thank you
Martin
