FAS2750 - Disk assign 18 SAS to controller A and 6 SSD to controller B

aautier · ‎2018-09-06

Hi everyone,

First time posting here.

On a new FAS2750 in cluster mode 9.4P1, I would like to assign all SAS disks (18) to controller node 1 and all SSDs (6) to controller node 2.

ADP auto assign SAS to both node and create the root aggregates.

Need to partition SSD disks create a root parttition on it and migrate SAS disk to controller 1.

I'm not able to do this by myself.

Could you please help?

Many thanks

Hi there,

Partitioning your SSDs to make a root partition for controller B is not useful - it does not improve performance of the system, as the root aggregate and root volume is only used for booting the system. I recommend to leave it as is - SAS partitions booting each controller, then have a SSD data aggregate on controller B. Can you help me understand what you are trying to acheive?

Can you post the output of these two commands to assist further:

storage disk show -partition-ownership
storage pool show
storage pool show-disks

Thanks!

Hi Alex,

Thanks for your reply.

The goal is to create only two aggregates. 1 SAS and 1 SSD.

STK25_CLUSTER_NETAPP::> storage disk show -partition-ownership
Disk     Partition Home              		Owner             	   Home ID     Owner ID
-------- --------- ----------------- 		----------------- 	   ----------- -----------

Info: This cluster has partitioned disks. To get a complete list of spare disk
      capacity use "storage aggregate show-spare-disks".

18 entries were displayed.

STK25_CLUSTER_NETAPP::> storage pool show
This table is currently empty.

STK25_CLUSTER_NETAPP::> storage pool show-disks
This table is currently empty.

So if my understanding is good, I only have to move data partition from C2 to C1.

And keep the root partition on C2.

Correct me if I'm wrong.
