Install Aplikasi
Install
$ sudo apt-get install open-iscsi
Pastikan ada /etc/iscsi supaya iscsiadm tidak complain
ln -s /etc/{iscsid.conf,initiatorname.iscsi} /etc/iscsi/
Edit Konfigurasi
Konfigurasi default ada di /etc/iscsi/iscsid.conf atau ~/.iscsid.conf. Buka /etc/iscsi/iscsid.conf
# vi /etc/iscsi/iscsid.conf
Set node.session.auth.username, node.session.auth.password dan parameter lainnya sebagai berikut:
node.startup = automatic node.session.auth.username = MY-ISCSI-USER node.session.auth.password = MY-ISCSI-PASSWORD discovery.sendtargets.auth.username = MY-ISCSI-USER discovery.sendtargets.auth.password = MY-ISCSI-PASSWORD node.session.timeo.replacement_timeout = 120 node.conn[0].timeo.login_timeout = 15 node.conn[0].timeo.logout_timeout = 15 node.conn[0].timeo.noop_out_interval = 10 node.conn[0].timeo.noop_out_timeout = 15 node.session.iscsi.InitialR2T = No node.session.iscsi.ImmediateData = Yes node.session.iscsi.FirstBurstLength = 262144 node.session.iscsi.MaxBurstLength = 16776192 node.conn[0].iscsi.MaxRecvDataSegmentLength = 65536
Versi minimal sekali, ubah
node.startup = manual
menjadi
node.startup = automatic
Restart
Restart open-iscsi
/etc/init.d/open-iscsi restart
Discovery Target
Jalanan discovery terhadap iscsi target host:
# iscsiadm -m discovery -t sendtargets -p ISCSI-SERVER-IP-ADDRESS
Jika iSCSI server IP address adalah 192.168.1.100, tulis:
# iscsiadm -m discovery -t sendtargets -p 192.168.1.100
atau
# iscsiadm --mode discovery --type sendtargets --portal 192.168.1.100
Akan keluar kira-kira
# iscsiadm -m discovery -t sendtargets -p 192.168.1.100 192.168.1.101:3260,3 iqn.1992-04.com.emc:cx.ckm00100900301.a3 192.168.1.102:3260,1 iqn.1992-04.com.emc:cx.ckm00100900301.b2 192.168.1.103:3260,4 iqn.1992-04.com.emc:cx.ckm00100900301.b3 192.168.1.100:3260,2 iqn.1992-04.com.emc:cx.ckm00100900301.a2
Login menggunakan perintah
# iscsiadm --mode node --targetname iqn.1992-04.com.emc:cx.ckm00100900301.a2 --portal 192.168.1.100:3260 --login
Restart iscsi
# /etc/init.d/open-iscsi restart
Cara Cepat
Login ke iSCSI target secara cepat
iscsiadm --mode node -l
Unload iSCSI target secara cepat
iscsiadm --mode node -u
Format iSCSI Volume
Seharusnya akan ada tambahan drive misalnya /dev/sdc. Gunakan /var/log/messages untuk melihat nama device:
# tail -f /var/log/messages
Jika nama device adalah /dev/sdc, masukan langkah berikut untuk membuat partisi:
# fdisk /dev/sdc
Format partisi tersebut:
# mkfs.ext3 /dev/sdc1
Mount file system:
# mkdir /iscsi # mount /dev/sdc1 /iscsi
