ASMを使うときにASM Diskgroupが現れて、MOUNTできなくなった上に、ASMインスタンスのalert.logに以下のようなエラが現れた：
ERROR: no read quorum in group: required 1, found 0 disks
ORA-15032: not all alterations performed
ORA-15017: diskgroup “TESTDG04” cannot be mounted
ORA-15063: ASM discovered an insufficient number of disks for diskgroup “TESTDG04”
ERROR: /* ASMCMD */ALTER DISKGROUP testdg04 MOUNT
これはASM Diskgroup上の部分、Metadataメータデータにロジック損害/一致していない事情が現れたと意味している。この場合にはkfed repairでリカバリしてください （10.2.0.5バーション後)
kfed repairでうまくいかない場合には、ASM底の構造に詳しいプロ技術員が人工的にロジック損害を修復するという方法しかない。

[oracle@mlab2 trace]$ oerr ora 15063
15063, 00000, “ASM discovered an insufficient number of disks for diskgroup \”%s\””
// *Cause: ASM was unable to find a sufficient number of disks belonging to the
// diskgroup to continue the operation.
// *Action: Check that the disks in the diskgroup are present and functioning,
// that the owner of the ORACLE binary has read/write permission to
// the disks, and that the ASM_DISKSTRING initialization parameter
// has been set correctly. Verify that ASM discovers the appropriate
// disks by querying V$ASM_DISK from the ASM instance.
//
[oracle@mlab2 trace]$ oerr ora 15017
15017, 00000, “diskgroup \”%s\” cannot be mounted”
// *Cause: The disk group could not be mounted by the ASM instance either
// of an IO error or due to other reasons explained in alert log or
// trace files.
// *Action: Check for additional errors reported. Correct the error and
// retry the operation.
//
[oracle@mlab2 trace]$ oerr ora 15032
15032, 00000, “not all alterations performed”
// *Cause: At least one ALTER DISKGROUP action failed.
// *Action: Check the other messages issued along with this summary error.
