To dicover this volume
from both nodes, hopefully you are aware of these iscsi commands Just giving examples
1) First discover
if these volumes are visible 1) #
iscsiadm --mode discovery --type sendtargets --portal 10.1.40.222 (where
10.1.40.222 is IP address of iscsi ) 10.1.40.2:3260,1 iqn.2007-06.com.unisys:prov 10.1.40.2:3260,1 iqn.2007-06.com.unisys:prov-goldilocks1 10.1.40.2:3260,1 iqn.2007-06.com.unisys:p3vmware 10.1.40.2:3260,1 iqn.2007-06.com.unisys:p2vmware You can see it is showing prov,
prov-goldilocks1,p3vmware,p2vmware volumes [whichever is created] 2)Login to iscsi iscsiadm --mode
node --targetname iqn.2007-06.com.unisys:prov
--portal 10.1.40.222
.login 3)do cat /proc/partitions It should show you /sd ** 4)mount that /dev/sd* to any of cluster [it should allow
you to mount from both nodes Just read some iscsi manuals and do this [withought GUI
you can do that ..Add new resource basically related to clustering resource
which automatically Mount your shared device when cluster manager is started ) So better configure it using iscsi commands and see whether
you can mount it from both nodes [then you can add a resource about it]

linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Singh Raina, Ajeet Ya,I have now created /newshare directory
on the both scsi initiator machine(cluster nodes). I made the following entry thru
system-config-cluster: Resource >> Add New Resource
>> Filesystem Name : Sharedstorage Mount Point : /newshare Device : /dev/sda6 Option : Filesystem type : ext3 Saved the file and sent to the other
Cluster Nodes. Now What Next? How will I know if the Shared Storage is
seen through both the Cluster Nodes? Earlier I had a script called duoscript on
both the Cluster Nodes.What I had tested: I ran the script on both the cluster
nodes.I stopped few processes on one of node,suddenly other took the
responsibility. Now where should I put the script on
shared Storage(target)? Pls Help From:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Re:When I click on Resource >>

point , Select any file system which you want to create in list ,you can choose
default file system ID there .. GUI will do the rest .. From:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Singh Raina, Ajeet Anyway, I am successful in setting Up iSCSI iniatiator and Target. What I did is Created a raw partition(unformatted ) on target machine
and restarted both the machine. I put : Lun 0 path=/dev/sda6 And That Did job for me. Now I can easily see: [root@BL01DL385 ~]# cat /proc/scsi/scsi Attached devices: Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: IET Model:
VIRTUAL-DISK Rev: 0 Type:
Direct-Access
ANSI SCSI revision: 04 The “Virtual DISk” Entry confirms that. Now I am making entry in #system-config-cluster and Want to know what exact entry I need to make
here: When I click on Resource >>
File System on Cluster Tool...It asked for Mount point, Device,
Option,Name,fil My machine address is 10.14.236.134. Path where Unformatted Partition made is
/dev/sda6 As for Now, I have only unformatted
partition?Do I need to format it? Pls Help From: Singh Raina,

Is above Entry Correct? My machine Hostname is pe.logical.com. Little confused about storage.lun1 whats
that? I have now not included any incoming or
outgoing user?Its open for all. What About Alias Entry? Ok After this entry being made, I have
confusion on client side too. The Doc says You need to make Entry on

machine with IP 10.14.236.134 as Target Machine and The two Nodes 10.14.236.106
