You can display disk group attributes with the V$ASM_ATTRIBUTE view and the ASMCMD lsattr command. For an example of the use of the V$ASM_ATTRIBUTE view, see Example 6-1. For information about the lsattr command, see "lsattr".
Disk group attributes can be set with the ATTRIBUTE clause of the ALTER DISKGROUP or CREATE DISKGROUP SQL statement and the ASMCMD setattr and mkdg commands. For information about the setattr and mkdg commands, see "setattr" and "mkdg".
You can also set disk group attributes with Oracle ASM Configuration Assistant (ASMCA). For information about managing disk groups with ASMCA, refer to "Managing Disk Groups with ASMCA".
