All, I'm getting the following error when trying to add a 3 Tb ASM disk under 11.2.0.3 ASM on REL 5.3: ORA-15099 disk <disk-name> is larger than the maximum size of 2097152 bytes Looks like it may be bug 10072750 or 6453944.8... Has anybody run into this? Is there a patch or workaround? The patch set notes for 11.2.0.3 say this is supposed to be fixed. Thanks very much for any help, Jerry-- //www.freelists.org/webpage/oracle-l
