How to change the disk ID's ?

[Maurice-FreeOnes]

We have 5 different 4 nodes clusters running an at the moment and almost in every cluster the disk ID's are different. For example in one they are the following when running the command "disk show":

Disk id 5.0.0, 5.0.1, etc and 7.0.0, 7.0.1, etc

When you start from scratch your disk id's are 0.0.0 or 1.0.0 (not sure or it starts at zero or one). Is it possible to change the disk ids from Disk id 5.0.0, 5.0.1, etc and 7.0.0, 7.0.1, etc into Disk id 1.0.0, 1.0.1, etc and 2.0.0, 2.0.1, etc? And if so how do you do this?

thanks for your time,

Maurice

"Disk id 5.0.0",  The first number corresponds to  Stack ID. The second corresponds  to Shelf ID, and the third number Is the bay number.

The Stack ID is auto assigned by the system. It cant be modified manually.

Hi Maurice,

Have you noticed this change recently or its something you think was misconfigured ?

The usual problem that can cause stack id change can either be cabling or a temporal duplicate shelf id

This has happened during migrations while adding new filers and taking older ones out of the stack.

Thank you, I am going to give this a try soon!

since stack id is auto assigned, so do i just need to trace shelf id and bay id to trace my disk?

As you know the the format  of disk id  is "stack_id.shelf_id.bay_number".

I just need last 2 to trace by disk?

Hi, Maurice-FreeOnes,

The first number is the automatically generated Stack ID by the system, the second number is the shelf ID, which can be modified, and the third number is the disk cage number ID. The slot number found by the disk is the slot number of that slot.
