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
