iSCSI Setup??

your_shadow03 · 07-11-2008, 12:26 AM

I have installed iscsi-target RHEL Machine with the following steps:

I have the following partition table:

1. I downloaded iscsi-target package and followed the process:

Code:

[root@localhost iscsitarget]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              29G  7.4G   20G  27% /
/dev/sda1             107M  9.6M   92M  10% /boot
none                  721M     0  721M   0% /dev/shm
/dev/sda3              20G   76M   19G   1% /home

Code:

#vi /etc/ietd.conf
Target iqn.2008-07.com.scsilinux:storage.disk2.sys1.xyz
        # Users, who can access this target. The same rules as for discovery
        # users apply here.
        # (no users means anyone can access the target)
        #IncomingUser joe secret
        #OutgoingUser jim 12charpasswd
        # Logical Unit definition
        # You must define one logical unit at least.
        # Block devices, regular files, LVM, and RAID can be offered
        # to the initiators as a block device.
        Lun 0 Path=/dev/sda3,Type=fileio

Saved the file.
And Then Started the service:

Code:

[root@localhost iscsitarget]# service iscsi-target restart
Stoping iSCSI target service:                              [  OK  ]
Starting iSCSI target service:                             [  OK  ]

Now, I went to setup iscsi-client on new system as:
Installed the Needed PAckage.
Pointed iscsi.conf to the target Machine.
And Then:

Code:

[root@BL02DL385 ~]# iscsi-ls
