Linux上iSCSI配置

1.修改配置文件
修改/etc/iscsi.conf文件，增加以下配置(还有很多参数可以配置):
DiscoveryAddress=172.16.35.228 TargetName=iqn.1987-05.com.cisco:test2 |
2.启动iscsi
[root@test2 ~]# /etc/init.d/iscsi start Checking iscsi config: [ OK ] Loading iscsi driver: [ OK ] Starting iscsid: [ OK ] |
3.观察日志
Nov 8 15:25:33 test2 kernel: iscsi-sfnet: Loading iscsi_sfnet version 4:0.1.11-1 Nov 8 15:25:33 test2 kernel: iscsi-sfnet: Control device major number 254 Nov 8 15:25:33 test2 iscsi: Loading iscsi driver: succeeded Nov 8 15:25:38 test2 iscsid[9664]: version 4:0.1.11 variant (12-Jan-2005) Nov 8 15:25:38 test2 iscsi: iscsid startup succeeded Nov 8 15:25:38 test2 iscsid[9668]: cannot make connection to 172.16.35.228:3260: Connection refused Nov 8 15:25:38 test2 iscsid[9668]: Connection to Discovery Address 172.16.35.228 failed Nov 8 15:25:39 test2 iscsid[9668]: cannot make connection to 172.16.35.228:3260: Connection refused Nov 8 15:25:39 test2 iscsid[9668]: Connection to Discovery Address 172.16.35.228 failed Nov 8 15:25:40 test2 iscsid[9668]: cannot make connection to 172.16.35.228:3260: Connection refused |
如果你看到如上错误，那么你需要启用NetApp的iSCSI支持并创建相应卷组。
4.配置好Netapp
此时日志显示:
Nov 8 15:43:38 test2 kernel: iscsi-sfnet:host0: Session established Nov 8 15:43:38 test2 kernel: scsi0 : SFNet iSCSI driver Nov 8 15:43:38 test2 kernel: scsi: unknown device type 31 Nov 8 15:43:38 test2 kernel: Vendor: NETAPP Model: LUN Rev: 0.2 Nov 8 15:43:38 test2 kernel: Type: Unknown ANSI SCSI revision: 04 |
这显示主机已经发现了iscsi设备
在dmesg输出中也可以看到这个信息
SCSI subsystem initialized iscsi-sfnet: Loading iscsi_sfnet version 4:0.1.11-1 iscsi-sfnet: Control device major number 254 iscsi-sfnet: Loading iscsi_sfnet version 4:0.1.11-1 iscsi-sfnet: Control device major number 254 iscsi-sfnet:host0: Session established scsi0 : SFNet iSCSI driver scsi: unknown device type 31 Vendor: NETAPP Model: LUN Rev: 0.2 Type: Unknown ANSI SCSI revision: 04 |
5.查看设备信息
此时可以使用iscsi-ls等命令查看相关Lun信息
[root@test2 etc]# iscsi-ls ******************************************************************************* SFNet iSCSI Driver Version ...4:0.1.11(12-Jan-2005) ******************************************************************************* TARGET NAME : iqn.1992-08.com.netapp:sn.84192734 TARGET ALIAS : HOST ID : 0 BUS ID : 0 TARGET ID : 0 TARGET ADDRESS : 172.16.35.228:3260,1 SESSION STATUS : ESTABLISHED AT Tue Nov 8 15:43:38 CST 2005 SESSION ID : ISID 00023d000001 TSIH 101 ******************************************************************************* |
