Funny disk name

Hi All,

We added 3 new draws today and we noticed one of the draws had funny device names shown on the partner node. The node itself is displaying the correct names. Contacted support and was told to halt both filers and restart the draw in question before bringing the filers back. I'll like to avoid doing this for obvious reasons.  Does anyone know how we can workaround this issue?

Thanks.

Re: Funny disk name

Such names are seen in case of duplicate shelf id. Verify that shelf has unique id. And yes, to change SAS shelf id you need poser cycle it.

Re: Funny disk name

We did have duplicate shelf ID and that was fixed and the new draw was power cycled but not the controllers. Any solutions of not having to halt both filers to fix this?

Re: Funny disk name

You could try takeover/giveback (which is in effect rebooting controller). But in general changing shelf configuration is twilight zone where everyone tends to be on the safe side and say it must be done offline.

Re: Funny disk name

Thanks for that, I'll give that a go.

Re: Funny disk name
