select name, state from v$asm_diskgroup

此视图在asm实例和db 实例中都能查询到。在这两个视图中看到的state是不一样的。

asm实例中state 返回MOUNTED

db 实例中state 返回 CONNECTED
对此视图的解释：

In an Automatic Storage Management instance, V$ASM_DISKGROUP displays one row for every disk group discovered by the Automatic Storage Management instance. In a database instance, V$ASM_DISKGROUP displays one row for every Automatic Storage Management disk group mounted by the local Automatic Storage Management instance.

State of the disk group relative to the instance:

CONNECTED - Disk group is in use by the database instance
BROKEN - Database instance lost connectivity to the Automatic Storage Management instance that mounted the disk group
UNKNOWN - Automatic Storage Management instance has never attempted to mount the disk group
DISMOUNTED - Disk group was cleanly dismounted by the Automatic Storage Management instance following a successful mount
MOUNTED - Instance is successfully serving the disk group to its database clients
