Hello. select header_status, path, name from v$asm_disk; HEADER_STATUS PATH NAME ------------ ------------------------------ -------------------- MEMBER /dev/rdsk/c6t4d0s6 MEMBER /dev/rdsk/c5t1d0s6 DATA_0000 MEMBER /dev/rdsk/c5t1d2s6 ORAFLASH_0000 Notice that /dev/rdsk/c6t4d0s6 does not have a name. Question is, how do I drop this disk from the diskgroup? I cannot use alter diskgroup data drop disk '/dev/rdsk/c6t4d0s6'; That is incorrect syntax. I need the name. Any ideas? PS: I tried (guessed) with name data_0001 but it gives error saying data_0001 not part of diskgroup DATA. Regards, NMK. -- //www.freelists.org/webpage/oracle-l
