Ultra 4 unresponsive after 10 minutes case#18114989
My Ultra 4 has been working perfectly for some time but today It suddenly became unresponsive and disappeared off the network. It did not show up in Raidar and I could not access the admin screen via...
Be advised that moving your disks from one brand of NAS to another will result in total loss of the data as the drives will be wiped, initialized and the volume set up. This is also true when moving from one platform to another (ReadyNAS currently has 3, Sparc, x-86 and ARM). The only way to preserve your data is to solve the problem or move the drives into another chassis of the same platform.
At noon on Mar 11, you thought you had solved the problem and then moved it back to it's normal position at which point you again lost connection. If this were mine, I would either go back to the connections and conditions you had in place then, or do a direct connection. At that point if you recover access to the unit I would first update your backup of all the data. This will at least give you something to fall back on.
The direct connection is a basic diagnostic test. You eliminate all the network components except for the single cable connecting the PC to the NAS. You will need to use a known good cable or if the direct connection does not seem to work, several different cables.
I had a problem with a brand new NVX over a year and a half ago. I had a network configuration that worked just fine with my NV+ and I added the NVX. I could copy files to it, but it would not allow me to copy files back. As the result of assistance of several members (including mdgm as I recall) I set up a direct connection and determined there was absolutely nothing wrong with my NVX. I had purchased a gigabit switch when I had the NV+ to increase the throughput, replacing a Netgear FS105. Once I removed the gigabit switch and restored the FS105, I could copy and retrieve files just fine (although at reduced speed because of the switch limitation). I ordered and currently have a Netgear GS108 switch in that position and everything is good.
You have a number of switches in your network and unless you have a lot of devices, six switches seems like a very complex arrangement. If you have that much equipment, you must have a lot of cables as well. Once you solve your problem, you might want to invest in a cable tester. You can get one for around $20 from Newegg. Cables can and do go bad. Break one of the 8 small wires as it comes out of the plug and it will not work.
