Hello,

I would like known if the shelf DS14MK2 SHLF,14.0TB SATA,QS,R5 can be connected in switch fabric (brocade) ?

Why my question... the cables are fiber when i connected this shelf in controller.

No, that’s not supported.

SATA drives in a Fabric MetroCluster are only supported when they are in DS4243 shelves.

Sirs, are you sure because my switch Brocade are detected all disks of the shelf as the following below:

But, when a set my fcpadmin config in mode initiator I have the follow message:

The WAFL could not login in device because this disks is SATA in Fibre Channel ? Or we have possibility to use this shelf in switch fabric?

Obs. Remember this Shelf have SATA disks (DS14MK2 SHLF,14.0TB SATA,QS,R5) but the back module in shelf is a AT-FCX (fibre input)

Tks

Do not confuse "it is not technically possible" with "it is not supported".

My question is if it is technically possible ?

Tks for your response.

Taking advantage about this topic, I would like share other question, about this case.

We have only two fibre inputs in FAS2040 are 0a, 0b. Also I have a Brocade Switch Fibre Channel (FabricOS)

I need to connect two differents shelfs (DS14MK2 SATA and DS14MK4 FC) in head controller.

We can connect DS14MK4 FC ESH4 shelf through Fabric Switch but unfortunately can not use DS14MK2 SATA in fabric topology, that you said (it's not supported).

The only solution was connect the 0a (fabric sw brocade in zoning with DS14MK4 FC ESH4 shelf ) and 0b direct attached with DS14MK2 SATA, that is work, all disks was detected BUT i receive one strange Alert:

Sun Mar 4 15:14:13 BRT [config.BadLocalSwitch:ALERT]: Disk sw-san1:1.37 is attached to a switch. However, there are also local attached disks. This is an illegal configuration.

Sun Mar 4 15:14:13 BRT [config.BadLocalSwitch:ALERT]: Disk sw-san1:1.32 is attached to a switch. However, there are also local attached disks. This is an illegal configuration.

Sun Mar 4 15:14:13 BRT [config.BadLocalSwitch:ALERT]: Disk sw-san1:1.36 is attached to a switch. However, there are also local attached disks. This is an illegal configuration.

... this alert for all FC disks

This ALERT is normal or i need change this topology?
What are my alteranatives ?

Tks again

What makes you believe that fabric shelf attachment is supported at all? The only supported configuration is FC shelves in Fabric Metrocluster.
