FAS8040 cabling with one DS4243

DangvPham — Wed, 04 Jun 2025 10:59:53 GMT

Hi experts,

I have a FAS8040 and one disk-shelf DS4243. Is that possible to connect the filers to one disk-shelf?

Any cable diagram for that connection?

Thank you so much,

Dang

Hello Dang,

Yes, you can attach the external shelf (s) in FAS8040.

You can follow review the 8040 Installation guide (page 3).

Note: DS4243 (IOM3) shelf modules are not supported on OS 9.4 and above.

Regards,

Aman

Thanks, Aman,

My issue is connecting FAS8040 to only 1 DS4243. It seems hard to find the specified diagram, also after that I stuck in LOADER Mode. Below is the error message:

It could be the wrong cable connect as I guest.

Hi Aman,

It seems my issue is connecting Dual filer FAS8040 to only one DS4243. I can't find any specified diagram for my case. So, it could be wrong cable connection as I guest. Below is the messages from my console.

Hi Dang,

You can check if the node is able to view the disks via sysconfig -v from the maintenance mode.

Also, disk show -v command can tell you if any disks are seen on the local node.

I have attached the cabling diagram, you can verify if it has been cabled this way.

Regards,

Aman
