[Linux-cluster] RE: iSCSI Setup as Alternative to Shared Storage..

Thu Jul 10 09:26:40 UTC 2008

So I have the following Entry at my ietd.conf file:

# iscsi target configuration 

Target iqn.2008-10.com.logical.pe:storage.lun1
        IncomingUser 
        OutgoingUser
        Lun 0 Path=/home/vjs/sharess,Type=fileio
        Alias iDISK0
        #MaxConnections  6

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 /etc/iscsi.conf file as:

# simple iscsi.conf

DiscoveryAddress=172.30.0.28
            OutgoingUserName=gfs
            OutgoingPassword=secretsecret
       LoginTimeout=15
       DiscoveryAddress=172.30.0.28

What's the above entry means?IP??

As for My Setup I am setting up RHEL 4.0 machine with IP 10.14.236.134
as Target Machine and The two Nodes 10.14.236.106 and 10.14.236 108 as
Already been in Cluster Nodes.

Thanks for Helping me out. But You need to also Help me What Entry in
Cluster.conf I need to make after these things being completed?

I want to setup iSCSI as I am running short of Shared Storage.

In one of the Doc
http://mail.digicola.com/wiki/index.php?title=User:Martin:iSCSI it says
that :

[doc]

Install the Target 

1. Install RHEL4, I used kickstart with just "@ base" for packages.
Configure the system with two drives sda and sdb or create two logical
volumes(lvm). The first disk is for the OS and the second for the iSCSI
storage

[/doc]

My Hard Disk Partition says:

[code]

[root at bl04mpdsk ~]# fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes

255 heads, 63 sectors/track, 9729 cylinders

Since I need to make entry on:

iscsi target configuration 

Target iqn.2000-12.com.digicola:storage.lun1
        IncomingUser gfs secretsecret
        OutgoingUser
        Lun 0 Path=/dev/sdb,Type=fileio
        Alias iDISK0
        #MaxConnections  6

In /etc/ietd.conf

Should I need to make separate partition or mention ??? under Lun 0
path=??? Entry?

If you wish you can create a separate partition. Else create a file &
give the full path of the file. [e.g path=/home/test/target_file]
