Hi guys,

How are you?

I am new at Ansible and doing some great stuffs until now.

I have those variables:

asm\_disks:

- { device: ‘sdc’, asm\_disk\_name: ‘ASM\_GRID01’, asm\_diskgroup: ‘GRID01’, asm\_redundancy: ‘NORMAL’, separator: ‘,’ }

- { device: ‘sdd’, asm\_disk\_name: ‘ASM\_GRID02’, asm\_diskgroup: ‘GRID01’, asm\_redundancy: ‘NORMAL’, separator: ‘,’ }

- { device: ‘sde’, asm\_disk\_name: ‘ASM\_GRID03’, asm\_diskgroup: ‘GRID01’, asm\_redundancy: ‘NORMAL’, separator: ‘’ }

- { device: ‘sdf’, asm\_disk\_name: ‘ASM\_DATA01’, asm\_diskgroup: ‘DATA’, asm\_redundancy: ‘EXTERNAL’, separator: ‘’ }

- { device: ‘sdg’, asm\_disk\_name: ‘ASM\_FRA01’, asm\_diskgroup: ‘FRA’, asm\_redundancy: ‘EXTERNAL’, separator: ‘’ }

- { device: ‘sdh’, asm\_disk\_name: ‘ASM\_REDO01\_01’, asm\_diskgroup: ‘REDO01’, asm\_redundancy: ‘EXTERNAL’, separator: ‘,’ }

- { device: ‘sdi’, asm\_disk\_name: ‘ASM\_REDO01\_02’, asm\_diskgroup: ‘REDO01’, asm\_redundancy: ‘EXTERNAL’, separator: ‘’ }

- { device: ‘sdj’, asm\_disk\_name: ‘ASM\_REDO02\_01’, asm\_diskgroup: ‘REDO02’, asm\_redundancy: ‘EXTERNAL’, separator: ‘,’ }

- { device: ‘sdk’, asm\_disk\_name: ‘ASM\_REDO02\_02’, asm\_diskgroup: ‘REDO02’, asm\_redundancy: ‘EXTERNAL’, separator: ‘’ }

I need to do something like this:

A loop to concatenate the asm\_disk\_name variable using comma (,), I know that I need to use join(‘,’)

The challenge is:

I need to concatenate all of asm\_disk\_name using comma breaking by asm\_diskgroup. So, for example: when loop changes from REDO01 asm\_diskgroup to REDO02, I need to register in another variable.

My expected output:

redo01:  
‘ASM\_REDO01\_01’,‘ASM\_REDO01\_02’

redo02:

‘ASM\_REDO01\_01’,‘ASM\_REDO01\_02’

How can I do that?

Thank you!

Marcus

Hello and welcome!

This is an interesting problem to try and solve, but I think it's a  
topic better suited for the Ansible Users[0] mailing list as this list  
is meant for discussion about the development of Ansible itself and  
not that of playbooks or general Ansible use.

Thank you and happy automating! 🙂
