13.2.2. Configuração do iniciador NVMe para os adaptadores QLogic

Procedimento

1. Instale a ferramenta nvme-cli:

   # yum instalar nvme-cli

   Copy to Clipboard Toggle word wrap

   Isto cria o arquivo hostnqn no diretório /etc/nvme/. O arquivo hostnqn identifica o host NVMe.

   Para gerar um novo hostnqn:

   #nvme gen-hostnqn

   Copy to Clipboard Toggle word wrap

2. Remova e recarregue o módulo qla2xxx:

   # rmmod qla2xxx
   # modprobe qla2xxx

   Copy to Clipboard Toggle word wrap

3. Encontre os sites WWNN e WWPN dos portos locais e remotos:

   # dmesg |grep traddr
   
   [    6.139862] qla2xxx [0000:04:00.0]-ffff:0: register_localport: host-traddr=nn-0x20000024ff19bb62:pn-0x21000024ff19bb62 on portID:10700
   [    6.241762] qla2xxx [0000:04:00.0]-2102:0: qla_nvme_register_remote: traddr=nn-0x203b00a098cbcac6:pn-0x203d00a098cbcac6 PortID:01050d

   Copy to Clipboard Toggle word wrap

   Utilizando estes valores host-traddr e traddr, encontre o subsistema NQN:

   nvme discover --transport fc --traddr nn-0x203b00a098cbcac6:pn-0x203d00a098cbcac6 --host-traddr nn-0x20000024ff19bb62:pn-0x21000024ff19bb62
   
   Discovery Log Number of Records 2, Generation counter 49530
   =====Discovery Log Entry 0======
   trtype:  fc
   adrfam:  fibre-channel
   subtype: nvme subsystem
   treq:    not specified
   portid:  0
   trsvcid: none
   subnqn:  nqn.1992-08.com.netapp:sn.c9ecc9187b1111e98c0800a098cbcac6:subsystem.vs_nvme_multipath_1_subsystem_468
   traddr:  nn-0x203b00a098cbcac6:pn-0x203d00a098cbcac6

   Copy to Clipboard Toggle word wrap

   Substitua nn-0x203b00a098cbcac6:pn-0x203d00a098cbcac6 pelo traddr.

   Substitua nn-0x20000024ff19bb62:pn-0x21000024ff19bb62 pelo host-traddr.

4. Conecte-se ao alvo NVMe usando a ferramenta nvme-cli:

   # nvme connect  --transport fc --traddr nn-0x203b00a098cbcac6:pn-0x203d00a098cbcac6 --host-traddr nn-0x20000024ff19bb62:pn-0x21000024ff19bb62 -n nqn.1992-08.com.netapp:sn.c9ecc9187b1111e98c0800a098cbcac6:subsystem.vs_nvme_multipath_1_subsystem_468

   Copy to Clipboard Toggle word wrap

   Substitua nn-0x203b00a098cbcac6:pn-0x203d00a098cbcac6 pelo traddr.

   Substitua nn-0x20000024ff19bb62:pn-0x21000024ff19bb62 pelo host-traddr.

   Substitua nqn.1992-08.com.netapp:sn.c9ecc9187b1111e98c0800a098cbcac6:subsystem.vs_nvme_multipath_1_subsystem_468 pelo subnqn.
