QUESTION 169

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

Sql> Startup Pfile=?/dbs/init+asm.ora ASM instance started

Total System Global area 104611840 bytes

Fixed Size 1298220 bytes

Variable Size 78147796 bytes

ASM Cache 25165824 bytes

Ora-15032:not all alterations performed

Ora-15063:asm discovered an insufficient number ofdisks for disk group "DGROUP3"

Ora-15063:asm discovered an insufficient number ofdisks for disk group "DGROUP2"

Ora-15063:asm discovered an insufficient number ofdisks for disk group "DGROUP1"

In trying to determine the cause of the problem, we issue this query:

Sql> Show parameter asm

NAME TYPE VALUE

------------------------------------ ----------- -------------------------_

Asm_allow_only_raw_disks Boolean FALSE

Asm_diskgroups string DGROUP1, DGROUP2, DGROUP3

Asm_diskstring string

Asm_power_limit Integer 1

Asm_preferred_read_failure_groups string

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 has 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 is 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.
