Just following along and thought I’d share a few things. First can you give us a more detailed picture of your network with last octet addresses? Something like this maybe:
INTERNET (Comcast Cable)
WIFI ROUTER (Linksys 1600N)
INTERNET/WAN IP: (X.X.X.X)
LAN IP: 192.168.1.1 (you can just use .1 or say .5)
LAPTOP (WIFI connection)
Wireless IP: .100
Ethernet IP: (x.x.x.x - please put the full IP you’re using)
LAN IP: (x.x.x.x - again the full IP please)
This way we can start asking question about connectivity and get some tests running. Can your laptop ping the Drobo IP? If you ping it constantly (add “-t” on command line) for say hours do you get the same drops/disconnects? What happens on the front of the FS, do the lights do anything? Do you get a good or bad status from them visually? Have you had Drobo Dashboard open while this happens?
I’ve not migrated from my FS to a new/upgrade but in the past I had to do a chassis swap just like you’re considering. For me it was like everything Drobo, just plug and play. Took each drive from my chassis and put them in the exact same slot position in the new chassis, power on and done.
Honestly I’m not sure i yet think your Drobo is the problem, something keeps telling me there is something else wrong. That said it’s a pretty damn simple setup when you’re just talking 2 devices with just a single cable between them. Pretty much 3 things that can be wrong, your computer/port, the cable, or the Drobo. I’m not sure why I think it’s something else, I’m probably wrong, just what my gut keeps thinking.
Oh and BTW someone tell me why half the migration guides below don’t have an “a” while the second half do? OMG it’s driving my OCD crazy, someone fix/change that ASAP!!!
