AFF A200 - single path ha

nemar07

Hi Community,

 

We have bought month ago AFF-A200 array with 12 internal disks (no additional shelves) . Engineer that cabled this array on site, cabled it wrong (SAS Cables)

 

Controller 1 0a to Controller 2 0a

Controller 1 0b to Controller 2 0b

 

Should be 0a to 0b and 0b to 0a.

 

No errors at all on SysMGR, sysconfig -a shows it as 

System Storage Configuration: Single-Path HA

 

As it has only internal disks, can it be recabled nondisruptively ?

Thanks

Hi

 

Yes, you can recable SAS cable nondisruptively , if you only have internal disks and dont have any additional shelves.

do you even need the SAS cabling on A220? with single path HA, will it affect disk failover to different controllers? Thx.

If a FAS or AFF controller with embedded storage has no additional external SAS storage shelves, the Node1 0a -> Node2 0b and Node1 0b -> Node1 0a SAS cable connections are a minor reliability enhancement to give you multipath HA connectivity for that internal shelf of drives. But, the internal path to the drives is deemed highly reliable - In fact, NetApp has stopped including the 2 x SAS cables for systems with only internal storage due to this fact.
