實驗環境：falcon存儲設備作服務器，redhat作客戶端
IPStor控制檯
首先掛載光盤，安裝iscsi相關的rpm包
[root@localhost ~]# mkdir /data [root@localhost ~]# mount /dev/cdrom /data mount: block device /dev/sr0 is write-protected, mounting read-only [root@localhost data]# cd /data/Packages/ [root@localhost Packages]# ll iscsi* -r--r--r-- 66 root root 670688 Oct 31 2012 iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm [root@localhost Packages]# rpm -ivh iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm warning: iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY Preparing... ########################################### [100%] 1:iscsi-initiator-utils ########################################### [100%] |
設置iscsi服務開機自動啓動
[root@localhost Packages]# chkconfig --level 35 iscsi on [root@localhost Packages]# chkconfig --level 35 iscsid on [root@localhost Packages]# chkconfig --list | grep iscsi iscsi 0:off 1:off 2:off 3:on 4:on 5:on 6:off iscsid 0:off 1:off 2:off 3:on 4:on 5:on 6:off |
向服務器192.168.188.129發送請求
此時服務器並未發現該設備

此時要開啓控制檯，在控制檯上掃描新設備，添加客戶端，即可
爲iscsi目標分配SAN資源：
然後爲客戶端分配資源
我們最終可以分配到3塊san資源
重新啓動服務，並再次發送請求，可以看到19e6f857b0b1-0已經找到

查看分區，多出了sdb，sdc，sdd，此次連接成功。
