How to mount LUN to linux host

to mount the lun to linux host do the following.
after creating the mapping view and adding the linux's initiator to the mapping.
go to linux and and scan for iscsi targets,
run the followings command to start iscsi and scan for luns.
1. /etc/init.d/iscsi start
Check iscsi status : /etc/init.d/iscsi status
restart iscsi : /etc/init.d/iscsi restart

Scan for target ip: iscsiadm -m discovery -t st -p x.x.x.x (where x.x.x.x is the ip of storage link connected to host)
Login iscsi target: iscsiadm -m node -t <IQN> -p x.x.x.x (where iqn is the initiator of storage and x.x.x.x is storage's ip)
if this login command doesn't work then do this to login all targets connected to that host: iscsiadm -m node -l

once this is done, check for the lun, and format it, Follow the procedure given below.
1. fdisk -l (to check the lun)
2. fdisk /dev/sdb (where /dev/sdb is your newly created lun, it can appear with any name)
then enter by this sequence
3. n>p>1>default>default>w (input these when fdisk asks you to input parameters)
after this, run again
4.fdisk -l
now /dev/sdb will appear as /dev/sdb1
now run
5. mkfs.ext3 /dev/sdb1
when its completed, your lun will be ready to mount
make a directory anywhere by
6. mkdir /test (where test is the name of new directory where we want to mount the lun)
Now you can mount
7. mount /dev/sdb1 /test
That's it. you are good to go, lun should be mounted now.
you can create a sample file by running following
touch hello.txt

Let me know if this solves the problem. Thanks

Hi, umairyaqub

The following is the suggestions on troubleshooting:

Storage:

1)       Confirm the port is configured with IP and it is in link-up status.

2)       Confirm the LUN/LUN group has been configured.

3)       Confirm the host/host group has been configured.

a)         Confirm the initiator has been created and the status is online. The IQN can be obtained from Linux OS.

b)         Confirm the storage is able to ping to the server OS.

                         i.              Login into storage using cli

a)         User: admin

b)         Password (Default): Admin@storage

                       ii.              Change to developer mode - change user_mode current_mode user_mode=developer

                      iii.              Change to minisystem

 

                      iv.              Ping to the server OS using the interface that is configured with the IP 192.168.7.5

 

4)       Confirm the mapping is done.

 

 

Switch:

1)       Confirm the switch configuration on port is correct:

If bond port is configured:

 

 

 

Host:

1)       Confirm that the server is able to ping to storage service IP and gateway.

 

l  If storage service IP is not ping-able, the possible causes are as below:

ü  Wrong cabling

ü  Switch configuration error

  Route is not configured

  VLAN is not configured

ü  Host network configuration error

  Gateway is not configured

  IP is not configured

ü  Storage service port configuration error

  Default route is not configured

  IP is not configured

 

2)       Confirm the configuration of iSCSI Initiator

a)         Make sure the iSCSI initiator package is installed. Try to run iscsiadm to check.

                         i.              If it is not installed, attach the Linux ISO and install the rpm file for iscsi-initiator-utils.

                       ii.              Then obtain the iscsi iqn - vi /etc/iscsi/initiatorname.iscsi

                      iii.              Once obtain the initiator, add the initiator in storage.

                      iv.              Then discover the storage - iscsiadm -m discovery -t st -p 192.168.7.5 -l

                       v.              Rescan the disk - rescan-scsi-bus.sh

                      vi.              Then fdisk –l to scan the disk, normally the new added disk is named as /dev/sdb

                    vii.              Then convert the drive to file system and mount to the system

Thank you.
