Thanks in advance for putting up with my newbie question.

Re: Why all the partners?

It means you have the dual-controller setup & these three disks are owned by the other controller.

So it looks like it has been configured for an 'active-passive' tandem where the controller you are looking at does the actual job, whilst the partner owns minimum number of disks (3) and take ownership only if the controller 1 fails.

The other option is to split disk ownership more or less evenly & run some workloads on both controllers.

Does it make sense?

Re: Why all the partners?

Yep, makes sense, thank you!

Re: Why all the partners?

Filer View dispalys disks which are owned by controller which you logged (data, partity, dparity, spare), and disks owned by second controller (partner). If you logon to second controller you will see that 0c.00.2, 0c.00.4, 0c.00.6 are data, parity parity, others are partner disk.

Best Regards,

Marcin

Re: Why all the partners?

Makes sense, sortof..er I guess I am not fully understanding then why all the other disks are partners as well?
