HI All ,
I have one storage device Netapp and want to access lun of
Netapp through iSCSI from openfiler 2.3 which is installed on
XenSource. I followed the following steps but not able to get disk in /dev
directory.
steps on netapp:
1. df -k
Filesystem total used avail capacity Mounted on
/vol/vol0/ 8388608KB 476784KB 7911824KB 6% /vol/vol0/
/vol/vol0/.snapshot 2097152KB 10952KB 2086200KB 1%
/vol/vol0/.snapshot
/vol/iscsiLunVol/ 31457280KB 20181396KB 11275884KB 64%
/vol/iscsiLunVol/
/vol/iscsiLunVol/.snapshot 0KB 232KB 0KB ---%
/vol/iscsiLunVol/.snapshotunVol/testlun1
2. nasa> lun create -s 4g -t linux /vol/iscsiLunVol/testlun1
3.nasa> lun show
/vol/iscsiLunVol/iscsitestlun 7.0g (7526131200) (r/w,
online, mapped)
/vol/iscsiLunVol/iscsitestlun2 7.0g (7526131200) (r/w,
online, mapped)
/vol/iscsiLunVol/testlun1 4g (4294967296) (r/w,
online)
4.nasa> iscsi initiator show
Initiators connected:
TSIH TPGroup Initiator
19 1000 openfiler (iqn.1993-08.org.openfiler.01.35ef13adb6d /
00:02:3d:00:00:00)
Ok, we see the openfiler host. Let's create the initiator group, called
openfiler2.
5. nasa> igroup create -i -t linux openfiler2
iqn.1993-08.org.openfiler:01.35ef13adb6d
6. nasa> igroup show
openfiler2 (iSCSI) (ostype: linux):
iqn.1993-08.org.openfiler:01.35ef13adb6d (logged in on: e0a)
We should assign the newly created Lun to the openfiler2 hosts.
7.nasa> lun map /vol/iscsiLunVol/testlun1 openfiler2
lun map: auto-assigned openfiler2=2
The check command:
8.nasa> lun show -v
/vol/iscsiLunVol/testlun1 4g (4294967296) (r/w, online,
mapped)
Serial#: hpGBe4AZsnLV
Share: none
Space Reservation: enabled
Multiprotocol Type: linux
Maps: openfiler2=2
go back to our initator host. Now everything is prepared to access the
4GB lun. The following command makes the disk accessible from the Linux
host.
9. openfiler:~# iscsiadm -m discovery -t st 192.168.2.222
<got list of target>
10. openfiler:~# iscsiadm -m node -T iqn.1992-08.com.netapp:sn.84211978
-p 192.168.2.222:3260 --login
11. openfiler:~# tail /var/log/messages
there is no line of " Attached disk" and I couldn't find any disk as
/dev/sd*
Kindly help me in this regard.
