Kuunza nekumisikidza SCSI disks kubva kuNAS

Mune yangu yazvino Work Center isu tine SAN iyo inoshandisa iyo a Psalms iyo nguva nenguva yandinoda kuwana kuti ndiwane kana kuisa imwe data.

Kugadzirisa uye kugovana zviwanikwa zveNAS zvatinoshandisa Mahara, iyo inotibvumidza isu kuwana maficha akagovaniswa kuburikidza CIFS, NFS, ftp o TFTP. Asi pane imwezve nzira "yekukwira" chero ipi yemapati akagadzirwa sedhisiki remuno pakombuta yedu.

Kune izvi isu tinofanirwa kushandisa iyo package kuvhura-iscsi.

Uye zvino mafaro anotanga:

1- Isa iyo yakavhurika-iscsi package

$ sudo aptitude install open-iscsi

2- Misa sevhisi:

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

3- Ita sevha yefaira /etc/iscsi/iscsid.conf uye wozozvigadzirisa.

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

4- Isa zvinotevera mune iyo faira:

node.startup = automaticnode.leading_login = Hapana node.session.auth.authmethod = CHAP node.session.auth.username = [chap_user] node.session.auth. .sendtivals.auth.username = [chap_user] discovery.sendtivals.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 nzvimbo. err_timeo.tgt_reset_timeout = 15 node.session.initial_login_retry_max = 30 node.session.cmds_max = 30 pfundo. Hungu node.session.iscsi.FirstBurstLength = 8 node.session.iscsi.MaxBurstLength = 128 node.conn [32] .iscsi.MaxRecvDataSegmentLengt h = 20 pfundo.

5- Isu tinochengetedza uye tinotangazve sevhisi kana kuitangisa:

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

6- Zvino kuti tione mavhoriyamu eSAN ataisa:

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

Mune yangu kesi zvingave:

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

7- Izvo zvazvinoita ndonyora iwo mavhoriyamu eSAN uye IQN yavo, uye inodzosera chimwe chakadai.

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

8- Ipapo isu tinosvika nemutemo:

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

Kubva panguva iyoyo, kana isu tikabata mune iyo terminal:

# fdisk -l

Tichaona kuti tichava nematanho ese kana mavhoriyamu eSAN, ayo atinogona kukwira sekunge rakaoma dhisiki kana ndangariro.

Kana tapedza, tinobvarura zvese zvatakashandisa uye kumisa sevhisi:

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