I have a NETAPP 8040 running cDOT 9.1. I have 12 shelves. 8 in rack1 and 4 in rack2. The 4 in rack 2 are 1 aggregate of SSD disks.
I now want to move physically the 4 shelves in rack 2 to rack 1. I have space enough to move first all the VMs (on Hyper-V) to a LUN on volumes already stored on shelves in rack1. So the aggregate on the shlves in rack1 will be empty (or not in use)
Can i just switch of the 4 shelves in rack2, move them to rack1 and power up ?
Or do i need to shutdown the whole Netapp for this operation ? and power up when the 4 shelves of rack2 are reconnected in rack 1 ?
To my view, to do it in live and in supported way you will have to
1. destroy the AGGR.
2. un-own the disks (disk removeowner)
3. hot-remove the shelves https://library.netapp.com/ecm/ecm_download_file/ECMP1119629 page 24
4. hot-add the sehllves 1 by 1 https://library.netapp.com/ecm/ecm_download_file/ECMP1119629 page 12
With live you mean the storage keeps working with all the Hyper-V hosts (and its VMs) online during the whole operation but the 4 shelves to move of course are just powered off after the destruction of the aggregate the unassignment of the disk owner ?
it depends on whether the 4 shelves in Rack 2 are on a separate loop/stack or not.
If they are part of a bigger loop/stack then you will almost certainly have to do a complete shutdown and then move the shelves (unless you can find a way to move the shelves without disconnecting the cables).
Hope this helps.
The 4 shelves in RACK2 are of type SSD; in the first RACK i have 2 aggregates: 1 with SAS disks and another with SSD disks.
Is the recommended cabling in this configuration that the SSD aggregates of rack 1 and rack 2 are separate circuits or just 1 ?
