RN2120 advertised storage, iSCSI volume, diagnostics
I've got a RN2120 with 4x 4TB disks loaded. Firmware was updated earlier in the week to 6.9.3. RAIDar finds it OK, tells me everything is fine and the available Diagnostics complete without error. I can login to it OK and all seems well. However, maybe it isn't configured correctly or there is some other issue because....... 1. In the iSCSI screen I can create a group but when I try and create a new LUN it reports that the max size available is just 8TB. I would expect that if I only had 3 drives but I have 4 of them. 2. No matter what LUN I create, it doesn't actually seem to get created. Well, nothing is ever displayed put it that way! Could this be down to a setting I've missed, a drive reporting that it's healthy when it isn't? Are there any proper system diagnostics tools around? Thanks in advanceSolved1.9KViews0likes8Comments
Nighthawk routers should have backdoor diagnostics
So, Nighthawk developers, a suggestion: Have an independent thread in the firmware, simple, clean, with a UDP socket open, that can dump router diagnostics to Genie, Up, other tool. Do NOT Use HTTP, AJAX, etc. Would be highly useful if Admin console unresponsive, a router hang that affected function, but left the router running and semi-functional. Could dump router config, transceiver status, BSSIDs, any critical data.21KViews2likes3CommentsRAIDar diagnostics reporting "Volume swap is 100.00% full"
RAIDar diagnostics is reporting that "Volume swap is 100.00% full", what does this mean and should I be concerned?
