I am installing a fresh install of 10g on a Solaris 10g foundation. When trying to set universal installer to use the candidate partitions for ASM, the field is empty, but when I chose show all, it shows the candidates and lists them as member partitions.

The install will go no further because I can't choose any or all of the partitions as ASM candidtes.

Does anyone have a remedy that will allow me to use the cadidates partitions as my data disk group and complete the installation?

Thanks,
Altamaha

Hi,

>> When trying to set universal installer to use the candidate partitions for ASM, the field is empty, but when I chose show all, it shows the candidates and lists them as member partitions.

It's just me, but I don't trust the Oracle GUI, for the same reasons you show!

Try the native commands instead, it can be more reliable:

sql> select name, header_status, path from v$asm_disk;

Other ASM commands include:

******************************************************************
sql> alter diskgroup dgroup1 add disk '/devices/disk1a' name disk1a;

sql> alter database add disk disk2;

sql> select name, header_status, path from v$asm_disk;

If you do not have any diskgroups and need to create a new disk group:

sql> startup nomount
sql> create diskgroup dgroup2 normal redundancy
FAILGROUP controller1 DISK
'/devices/disk1a',
'/devices/disk2a',
failgroup controller2 DISK
'/devices/disk1b',
'/devices/disk2b';

Also, Aee Mike Ault's Oracle 10g Grid book for lot's of ASM command examples:

Hope this helps. . .

Thanks for the response Don, but, at present I do not have an installation, thus sql commands would not be available.

I am installing fresh from 10g CD downloaded from metalink. The ASM instance is being built during initial install, and all is well until I get to the point where I tell the installer which slices or partitions to use for storage management.

Oh . . .

Most of the installer issues I've seen deal with not having enough RAM of disk space.

Have you verified the pre-installation checklist?

Yes.. I have looked over the pre-install several times to make sure that I did not miss something... even thogh it looks like I must have if no one other than me has had this issue come up.

Hi Don,

Can you please help to understand the below query?.

Initially when there is a need to add disk in ASM on Oracle Linux system, Storage Team will provide LUN to DBA Team and DBA will create logical disks using "oracleasm createdisk command" but how to create disks on AIX system?

How to create logical disk on AIX system once got LUN from storage team?.

Regards,
Rupesh
