Create a new RSE

$ rucio-admin rse add QOS-A-PIC
Added new deterministic RSE: QOS-A-PIC

Add protocol about RSE (endpoint:port//prefix)

$ rucio-admin rse add-protocol --hostname xrootd.pic.es --scheme root --prefix '/pnfs/pic.es/tape/' --port 1094 QOS-A-PIC

Add attribute on RSE

$ rucio-admin rse set-attribute --rse QOS-A-PIC --key QOS --value A
Added new RSE attribute for QOS-A-PIC: QOS-A

List RSE with QOS=A

$ rucio list-rses --expression 'QOS=A'
QOS-A-PIC
