Pastikan paket rpcbind atau portmapper diinstal di host Linux. Jalankan:
# rpm -qa | grep rpcbind
Tindakan ini akan menampilkan sesuatu seperti: rpcbind-0.1.6+git20080930-6.15
Jika tidak melihat apa pun, Anda harus menginstal paket menggunakan YaST atau
zypper:
Menggunakan YaST: # yast2 --install rpcbind
Menggunakan Zypper: # zypper install rpcbind
Mempelajari informasi klien NFS dari host Linux
Paket dan versi klien NFS yang disetujui Pencadangan dan DR harus diinstal di
host.
Periksa apakah layanan portmapper atau rpcbind sedang berjalan. Jalankan:
# sudo service rpcbind status
Host Red Hat RHEL 6 atau CentOS Linux akan menampilkan sesuatu seperti:
rpcbind (pid 1591) is running...
Host Linux SLES akan menampilkan sesuatu seperti:
Checking for service rpcbind running
Jika layanan rpcbind tidak berjalan di host Linux, mulai dengan:
# sudo service rpcbind start
Gunakan rpcinfo untuk mencantumkan program atau layanan RPC yang terdaftar. Portmapper
harus terdaftar dan berjalan.
# sudo rpcinfo -p
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
Periksa apakah host Linux dapat melakukan panggilan RPC ke program rpcbind dan NFS di
perangkat pencadangan/pemulihan menggunakan perintah berikut.
# sudo rpcinfo -T tcp <#vm internal IP> rpcbind
program 100000 version 2 ready and waiting
program 100000 version 3 ready and waiting
program 100000 version 4 ready and waiting
# sudo rpcinfo -T tcp <#vm internal IP> nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
Jika perintah sebelumnya menampilkan output yang ditampilkan, konektivitas NFS dari
host Linux ke appliance pencadangan/pemulihan sudah baik.
