I've got a question regarding a brand new implementation and the way ADP has partitionned my disks. The system is a FAS2650 with 12*960GB SSD, it came with ONTAP 9.1P7 and has been upgraded to 9.2P2.
As described below (coming from the attached document, Page 43) I exepected the following layout:
But instead of that, I've noticed into the configAdvisor report that my partitions are configured like this:
Node A, disks: 0-2-4-6-8-10
Node B, disks: 1-3-5-7-9-11
(I'm only talking about root paritions, no data aggregate has been configured yet)
My question is, should I keep this configuration? I mean, in the attached document this configuration is valid for a AFF A200 system but not for FAS... I don't really know what is the impact if there's one...
My gut feeling is that integrated systems (which AFF A200 is) default to even/odd bay . But yes, I'd love to see defaults explained somewhere, including description of what "bay" disk auto assignment policy actually does.
I got an underlying question, customer wants to use Flash Pool with remaining data from these SSDs, the related documentation says:
"You cannot use SSDs that have been partitioned for root-data partitioning in a storage pool"
How can I configure FlashPool with this partitioning? Synergy tool shows a different a different root-data partitioning layout with 11*53.88GiB partition for root aggregate instead of 5*143.65GiB I had out of box...
If I understand the question correctly, the system has partitioned the SSDs, so it is probably an all-SSD or AFF config system, and there is no need for a FlashPool under this configuration. You are welcome to send me a DM with the serial number of the system and I will review what it shipped with if you wish.
The solution to repartition the disk sounds good but, what about the root partitions? Should I move it to the disk shelf HDD? Since we cannot do ADP on external disk shelves, this would lead us to "lose" multiple 8TB disks... Please find below the initial Synergy output, which I really have difficult to understand. The first one is a FAS2650 + 12*960GB SSD configuration, no shelf and matching with our disks layout:
But as soon as I add the shelf to the configuration:
In this configuration, where are located the 11*53.88GB parititions?
-> If it's on flash, how are the Flash Pools created ?
In the case of the original poster here, we have corresponded externally, and identified that the system was shipped with 9.1, then upgraded to 9.2, which does not repartition the drives to the 9.2 standard. We have identified that the most appropriate way forward is to verify there is no data present, and then wipe and repartition using option 9a then 9b from the boot menu.
