配置linux iSCSI target

1.配置iscsi-initiator-utils包

[root@ora10g Server]# rpm -ivh iscsi-initiator-utils-6.2.0.868-0.7.el5.i386.rpm 
warning: iscsi-initiator-utils-6.2.0.868-0.7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing...                ########################################### [100%]
   1:iscsi-initiator-utils  ########################################### [100%]
[root@ora10g Server]# 

2.扫描设备,发现还需要安装iscsi-target

[root@ora10g Server]# iscsiadm -m discovery -t sendtargets -p 192.168.20.128:3260
iscsiadm: can not connect to iSCSI daemon (111)!
iscsiadm: can not connect to iSCSI daemon (111)!
iscsiadm: Cannot perform discovery. Initiatorname required.
iscsiadm: Discovery process to 192.168.20.128:3260 failed to create a discovery session.
[root@ora10g Server]# 

3.去sf.net下载iscsitarget包进行编译

[root@ora10g Server]# 
[root@ora10g Server]# cd /softdb/
[root@ora10g softdb]# ls
