今天在为ASM添加磁盘组添加磁盘扩展空间时,遇到以下错误
-
SQL> alter diskgroup data add disk '/dev/rhdisk12';
-
alter diskgroup data add disk '/dev/rhdisk12'
-
*
-
ERROR at line 1:
-
ORA-15032: not all alterations performed
-
ORA-15075: disk(s) are not visible cluster-wid
-
看一下 ORA-15032 和ORA-15075 的错误解释
-
[oracle@mhxy162 ~]$ 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.
-
//
-
[oracle@mhxy162 ~]$ oerr ora 15075
-
15075, 00000, "disk(s) are not visible cluster-wide"
-
// *Cause: An ALTER DISKGROUP ADD DISK command specified a disk that could
-
// not be discovered by one or more nodes in a RAC cluster
-
// configuration.
-
// *Action: Determine which disks are causing the problem from the
-
// GV$ASM_DISK fixed view. Check operating system permissions
-
// for the device and the storage sub-system configuration on
-
// each node in a RAC cluster that cannot identify the disk.
ORA-15075 提到'
Check operating system permissions for the device' ,可以通过gv$asm_disk 查看。记得修改/dev/rhdisk12文件的属组为grid:oinstall
-
ls -l /dev/rhdisk12
crw------- 1 grid oinstall 24, 12 8月23 15时06 /dev/rhdisk12
