We have FAS8060 running 8.3.2 CDOT. We have two stacks , Stack A have 5 shelves 30-34, Stack B has one shelf 40. They are exactly the same shelf model and speed and the disks are also the same. I want to combine them to free up the SAS port. Im guessing this will require downtime? I am thinking, re-id shelf 40 to shelf 35 then add to Stack A. I just need to know if downtime is required.
In my opinion I prefer to do a quick downtime windows
- First plan very well the new SAS and ACP cabling, send ASUP to know your old configuration, then stop applications, disable cluster and halt filer. - Wait until LOADER prompt on both nodes - Make new SAS and ACP cabling - Set new shelf ID and restart shelf to commit the change - On both nodes from LOADER prompt tipe "boot_ontap menu" - in 1-8 menu select option 5 - Validate new shelf ID change and disk showing correctly - Then halt, and boot_ontap - When filer comes online enable cluster and validate cabling
- Restart Applications
- Send new ASUP ending downtime windows.
In my opinion is the more secure and reliable way to make the work you want.
