stor2rrd : I like define PORT alias for DS8800

Hi expert
I defined storage-list.cfgin
DS8870_iOPA:DS8K:IBM.2107-75ZZ261:xxxxxxxxxxxxxxxxxxxxx

and I defined in alias.cfg these port alias
PORT:DS8870_iOPA:0000:AIX1_B
PORT:DS8870_iOPA:0001:WIN1_B
PORT:DS8870_iOPA:0002:OTH1_D
PORT:DS8870_iOPA:0003:SVC_B

I run load.sh and I waited 30 minutes

I like to see in the Port->Item instead of 0000 AIX1_B but I see 0000

Why ?

Thanks
Emilio
