If a single SFP shows a low vaultage, there is an electrical fault in the SFP and it should be replaced. Standard operating voltage for an SFP is 3.3V (3,300 Millivolts). This parameter is important - if the current is zero ("0.000") mAmps, the SFP in the FC switch is faulty and needs to be replaced.įor Short-Wave SFPs, normal current is typically around 7.000 mAmpsįor long wave transcievers, this value will be higher (e.g. Very cool - the ports come with a multimeter! Worth double checking when making a new connection, in case the SFPs at each end don't match or the cable isn't supported

This doesn't take patching/connector attenuation into account - if you have lots of patch points etc, this transmission distance will be smaller.Ĩ50nm will be Short Wave & Multi Mode. The cable specifications are printed on the cable. 9u is Single-Mode (the value is zero because this SFP doesn't support Single Mode), 50u is OM2/OM3/OM4 cable, 62.5u is OM1 cable. This shows the maximum supported transmission distance for the specified type of cable. Supported speeds are in Megabytes per second, so this needs to be multiplied by 10 to get the megabits (or divided by 100 for gigabits) - 800 = 8Gbps Options: 003a Loss_of_Sig,Tx_Fault,Tx_Disable monthly via "supportshow"), it will give you an excellent baseline to compare against when a fault occurs.īelow is an example of a relatively healthy port switch01> sfpshow 3 Ideally if you can capture this output regularly (e.g. This command will print stats pertaining to a particular port on the switch.

SFP (Small Form-Factor Pluggable optical/copper transciever).

FC HBA (PCI Host Bus Adapter in the server or storage).

Alternately, perhaps you have extremely high latency on just one ESX hosts with regular storage disconnections (even though the link light looks fine)Īt a high level, it is likely to be one of the following, but you don't want to go through and replace/re-seat/test each of these components: So you've hit a situation where a Fibre Channel link light has gone out and you don't know what is wrong.

Please remember to mark the replies as answers if they help and unmark them if they provide no help. My suggestion is building a new Server and migrate the data from the old one. Troubleshooting is difficult and time consuming, some of them end in reinstallation. > enable-netadaptervmq on the adapters to no avail either.īesides, there are a lot of posts about the issues caused by converting.

I've installed the latest driver still no luck. Yes it says it supports both Vmware NetQueue and MS VMQ. You may contact DELL technical support to see if it is supported. I checked the document on official website, and didn't find related information if VMQ is supported. the two servers were running vmware esxi before. Sorry for the confusion, by converting i mean reinstalling the servers with Hyper-V/Windows 2012 R2 Server Core. I am in the process of converting two Vmware ESXi servers into a Hyperv cluster.Īre you converting VMs to physical? Or VMs to VMs?
