QUESTION 531

When starting up your ASM instance, you receive the following error:




What is the cause of the error?

A. The ASM_DISKGROUPS parameter is configured for three disk groups: DGROUP1, DGROUP2, and

DGROUP3.

The underlying disks for these disk groups have apparently been lost.

B. The format of the ASM_DISKGROUPS parameter is incorrect. It should reference the disk group

numbers, not the names of the disk groups

C. The ASM_POWER_LIMIT parameter is incorrectly set to 1. It should be set to the number of disk

groups being attached to the ASM instance.

D. The ASM_DISKSTRING parameter is not set; therefore disk discovery is not possible.

E. There is insufficient information to solve this problem.

Correct Answer: D

原因是

D . ASM_DISKSTRING 参数没有设置，不可能发现磁盘

答案是:D

ASM_DISKSTRING Initialization Parameter Note: Only Automatic Storage

Management instances support the ASM_DISKSTRING initialization

parameter. The syntax for assigning a value to the ASM_DISKSTRING

initialization parameter is as follows: ASM_DISKSTRING =

‘path1’[,’path2’, …] In this syntax, pathn is the path to a raw

device. You can use wildcard characters when specifying the path.
