open-SCSI help on equallogic

Question

Hi. I've got an Equallogic PS4000. I can connect a Windows 2008 server using the Microsoft ISCSI initiator with no problems.

I have an AMD64 Debian Squeeze server I'm trying to connect vis open_ISCSI. I have one NIC (eth0) set on a different subnet from my primary network. I run the discovery and can see the target to which I wish I to connect, but when I try to login, I get the following:

iscsiadm: Could not login to [iface: default, target: iqn.2001-05.com.equallogic:0-8a0906-d287b050c-d14000003874ecd1-dogwoodspace, portal: 10.200.0.255,3260]:
iscsiadm: initiator reported error (4 - encountered connection failure)

I'm flummoxed as to why I'm getting this connection error and have been beating my head against my desk for three days. Any help will be greatly appreciated.

Ensure you setup the Access List on the array for the dogwoodspace volume to the IP address (or iqn name of the initiator) of the Host. This can be done in the array GUI or via the CLI.

Looking at the error message, the IP address of the host is 10.200.0.255, is this a 24bit subnet? If so, .255 is a broadcase address, and can't be used for a host.

Review the Open-iSCSI.org Software iSCSI Initiator Configuration Guide (a little dated, we are in the process of updating this link)

media.community.dell.com/.../open-iscsi-initiator-install-v1.05.pdf

Also, are you using the latest Package: open-iscsi (2.0.871.3-2squeeze1): packages.debian.org/.../open-iscsi

Sigh. This is what happens when dumb people (me) with not enough knowledge of TCP/IP try to engage in configuration. I had the group IP configured as .255. Changed it to .200 and it worked.

Thanks so much for the fast response! I should have posted yesterday.
