ORA-15032: 未执行全部变更操作

ORA-15017: 无法装载磁盘组 ""

ORA-15063: ASM 发现磁盘组 "" 的磁盘数目不足

 

 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.
 
 
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.
 
 
 
 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.

ASM 不mount ASM 磁盘组，因为它发现磁盘不足。由于OCR磁盘储存在ASM中，这防止Oracle集群件的CRS 启动：

(1) 这些条目与 Note:1384692.1类似

原因

但是，问题不是ASM未发现所有磁盘，而是发现重复的磁盘 （即，ASM不是仅发现了5个所需的ASM磁盘，而是发现了两倍，即10个磁盘。）

当ASM不止一次发现了同一磁盘 ，它会忽略条目（v$asm_disk.mount_status=IGNORED），所以就像是发现了不足的磁盘。

因此，ASM警报日志在实例启动序列时显示条目”ERROR: -5(Duplicate disk …” 并在之后显示磁盘不足的错误(ORA-15063)。
.
解决方案ION

注：发现重复磁盘取决于所使用的平台。

在这个情况下 (Solaris)，需要进行以下操作识别重复设备：

* 根据以前mount 所有ASM磁盘组的ASM警报日志条目的成功尝试，需要以下ASM磁盘：

NOTE: cache registered group DATASOA number=1 incarn=0xa9eac7b8
NOTE: cache registered group DATA number=2 incarn=0xaa0ac7b9
NOTE: Assigning number (1,0) to disk (/oracle_crs_install/shr_disk_links/ora_dbdsk1) <— 4 disks for DATASOA
NOTE: Assigning number (1,2) to disk (/oracle_crs_install/shr_disk_links/ora_dbdsk2)
NOTE: Assigning number (1,3) to disk (/oracle_crs_install/shr_disk_links/ora_dbdsk3)
NOTE: Assigning number (1,1) to disk (/oracle_crs_install/shr_disk_links/ora_dbdsk4)
NOTE: Assigning number (2,0) to disk (/dev/rdsk/c0t60050768018105880000000000000023d0s6) <— 1 disk for DATA

* The Grid-plug-and-play profile or <Grid Infrastructure Home>/gpnp/<hostname>/profiles/peer/profile.xml, lists the disk discovery string that will be used (along with the spfile that will be use):

DiscoveryString=”/oracle_crs_install/shr_disk_links/ora_dbdsk*,/dev/rdsk/c*23d0s6″ SPFile=”+DATA/wlsoadbt1-clust/asmparameterfile/registry.253.778542929″

* From the above, it was found that ASM was discovering It was found that

/dev/rdsk/c0t60050768018105880000000000000035d0s6 <– dupl
/dev/rdsk/c0t60050768018105880000000000000034d0s6 <– dupl
/dev/rdsk/c0t60050768018105880000000000000033d0s6 <– dupl

/dev/rdsk/c0t60050768018105880000000000000038d0s6 <– dupl
/dev/rdsk/c0t60050768018105880000000000000023d0s6
/oracle_crs_install/shr_disk_links/ora_dbdsk1
/oracle_crs_install/shr_disk_links/ora_dbdsk2
/oracle_crs_install/shr_disk_links/ora_dbdsk3
/oracle_crs_install/shr_disk_links/ora_dbdsk4

* 由于重复磁盘被识别并分离，请更改它们的设备所有者：以ASM不再发现（访问）它们的方式更改组或文件权限。
ASM可以容忍每个ASM磁盘只发现一次（不超过一次，否则会被认为是“重复的磁盘”，就可能会遇到这种情况。
