Hello Andre,
As my colleagues informed you, whenever a path goes dead, PowerPath increases the counter to inform you that at some point from the last reboot, that particular path died. The more dead/alive events occur, the higher the number in the counter.
Unfortunately, PP will not give you more specific details on when a path died or came back alive. For that, you would need to look at the system event log. Event 100 (dead) and 101 (alive) will be logged and you can take the timestamp of when does happened.
As you mentioned, the command "powermt restore" will clear the error counter manually. Another way the counters will be cleared automatically is after a server reboot.
One thing that possibly happened to caused the single path errors is due to Plug and Play. It is common for a Windows server to reset the connection after the LUN driver finishes its installation. This can happen soon after the path was presented to the server or soon after the server reboot. For more information on this, pleas see KB 90938 (https://www.support.emc.com/kb/90938/).

Hi Andre,
PowerPath would note an error if path error was seen, path dead/alive. More specific information about the error would be found in the system event log. This reporting of the error will increment if additional errors occur and will be kept in the output until the next server reboot. In your case above, there appears to have been a path error on all paths to devices from host to SPA6.

It appears to be a historical error from the GUI as the paths are now active but not sure if only reported against SP port A6.
You would have to check the system event logs to see why this error is being reported against all luns and if only against port A6
You can run a powermt display dev=all in the command prompt and with the system event logs could see why this error is being reported.
My best recommendation would be to open an SR with EMC and please get emc host grabs from host in question provided so that we may see what is the issue occurring from a host perspective.

Thanks you Priscilla and dstratton for answer.
Additionally I used the command "powermt restore" to clean the console erros.
Tks!
