Issue with cfgadm

I have an issue with on T3-Lun where Veritas dont like it anymore and OS-system have issues with it too.

So I thought to unconfigure it but even that does not work

cfgadm -al | grep c17
c17::50020f230000eae0 disk connected unconfigured unkown

then I tried a

cfgadm -c unconfigure c17::50020f230000eae0 

that comes back quickly , ok I thought now I can do a

cfgadm -c configure c17::50020f230000eae0 

but get the:

cfgadm: Library error: failed to create device node 50020f230000eae0 : Invalid argument

It means that the occupant [LUN] isn't visible through the LINK, you need to either look into the cable running or check the zoning in case the cable is OK, and then look for reconfiguration.

ensure you're using the correct controller
