Weird Error while mapping SAN disks through NPIV

Hello,

While adding new Luns by using NPIV interfaces, I have errors on dmesg and syslogs
I can see clearly my new disks, the error repeats at everytime I run ioscan/insf, is this normal ?

Info :

Presumably you mean you can see your disks using the new agile DSF mechanism (i.e. under /dev/disk and /dev/rdisk) - can you see them corerctly under the legacy DSF mechanism (i.e. under /dev/dsk and /dev/rdsk) - it would be interesting to see what "ioscan -m dsf" reported (i.e. do you see all the legacy DSFs for each agile DSF?)

Never seen this error message before, but it almost suggests that the disk array isn't set up to use HP-UX's addressing scheme (i.e. for cXtYdZ -  X must be <255, Y must be <14 and Z must be <8). So what sort of disk array are you using, and have you checked it is set up correctly to serve LUNs to HP-UX?

 

If you don't use legacy DSFs at all, you could disable them using "rmsf -L" and see if that fixes your problem (although I suspect you are just masking an issue there rather than fixing it), you can always turn legacy DSFs back on later using "insf -L".
