Ana shigo da hawa disks na SCSI daga NAS

A cikin Cibiyar Ayyuka na yanzu muna da SAN wanda kuma yana amfani da NAS wanda lokaci zuwa lokaci Ina buƙatar samun damar don samo ko sanya wasu bayanai.

Don sarrafawa da raba albarkatun NAS da muke amfani dasu KyautaNAS, wanda ke bamu damar samun damar raba manyan fayiloli ta hanyar Farashin CIFS, NFS, FTP o TFTP. Amma kuma akwai wata hanyar da za a iya "hawa" kowane bangare da aka kirkira azaman diski na gida akan kwamfutarmu.

Don wannan dole ne muyi amfani da kunshin bude-iscsi.

Kuma yanzu fara farawa:

1- Sanya kunshin bude-iscsi

$ sudo aptitude install open-iscsi

2- Tsaida sabis:

$ sudo /etc/init.d/open-iscsi stop

3- Yi ajiyar fayil din /etc/iscsi/iscsid.conf sannan a gyara shi:

$ sudo cp /etc/iscsi/iscsid.conf /etc/iscsi/iscsid.conf.origin $ sudo nano /etc/iscsi/iscsid.conf

4- Sanya mai zuwa a wannan file:

node.startup = automaticnode.leading_login = Babu node.session.auth.authmethod = CHAP node.session.auth.username = [chap_user] node.session.auth.password = [chap_password] Discover.sendtargets.auth.authmethod = CHAP gano .sendtargets.auth.username = [chap_user] Discover.sendtargets.auth.password = [chap_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 = 5 node.conn [0] .timeo.noop_out_timeout = 5 node.session.err_timeo.abort_timeout = 15 node.session.err_timeo.lu_reset_timeout = 30 node.session. err_timeo.tgt_reset_timeout = 30 node.session.initial_login_retry_max = 8 node.session.cmds_max = 128 node.session.queue_depth = 32 node.session.xmit_thread_priority = -20 node.session.iscsi.InitialR2mediaT = Noode. Ee node.session.iscsi.FirstBurstLength = 262144 node.session.iscsi.MaxBurstLength = 16776192 node.conn [0] .iscsi.MaxRecvDataSegmentLengt h = 262144 node.conn [0] .iscsi.MaxXmitDataSegmentLength = 0 Discover.sendtargets.iscsi.MaxRecvDataSegmentLength = 32768 node.session.nr_sessions = 1 node.session.iscsi.FastAbort = Ee

5- Muna adanawa kuma sake kunna sabis ko fara shi:

$ sudo /etc/init.d/open-iscsi restart

6- Yanzu dan ganin adadin SAN da muka sanya:

# iscsiadm --mode discovery --type sendtargets --portal [IP del SAN]

A halin da nake ciki zai kasance:

# iscsiadm --mode discovery --type sendtargets --portal 192.168.24.20

7- Abinda yake yi shine lissafa kundin SAN da IQN dinsu, kuma ya dawo da wani abu kamar haka:

iqn.2002-10.com.infortrend:raid.sn7817070.001

8- Sannan muna samun dama tare da umarnin:

# iscsiadm --mode node --targetname iqn.2002-10.com.infortrend:raid.sn7817070.001 --portal 192.168.24.20:3260 --login

Daga wannan lokacin, idan muka zartar a cikin tashar:

# fdisk -l

Zamu ga cewa zamu sami dukkan bangarori ko kundin SAN, wanda zamu iya hawa kamar dai shi diski ne ko ƙwaƙwalwar ajiya.

Bayan mun gama, mukan kwance duk abin da muka yi amfani da shi mu tsaida sabis:

$ sudo /etc/init.d/open-iscsi stop
